     FIELD 
     Embodiments described herein relate generally to an electronic apparatus, a program recommendation system, a program recommendation method, and a program recommendation program. 
     BACKGROUND 
     An electronic apparatus which receives and records a program provided by a broadcaster or a distributor and plays back the program according to a request from the user, such as a recording device (hereinafter referred to as a client device or a user) connected to a television receiver or a monitor (display) device, for example, is capable of acquiring a variety of types of information via a network such as the Internet. 
     The client device (user) is capable of recording a number of programs. Further, the user (client device) can access a variety of databases via the network. For example, the user is capable of acquiring characters, main content, and the like (names of main solo performers and group performers in a music program, for example) of a recorded program from a database (external service/server) on the network on the basis of the program name (program title), broadcasting station (channel name), and broadcast date and time of the program. 
     A television receiver which prompts the user to record or view a program on the basis of information provided by the network, however, requires the user to enter a variety of elements, such as inputting a keyword and setting a genre, in a process of specifying a program desired by the user. 
     Even after it becomes possible to specify the name of a group that appears in the program, in order for the user to specify an individual belonging to the group and to be prompted to record or view the program desired, a special input (setting) approach or a complex combination is required in inputting a keyword, setting a genre, or the like.

     DETAILED DESCRIPTION 
     Various embodiments will be described hereinafter with reference to the accompanying drawings. 
     In general, according to one embodiment, an electronic apparatus comprising a group specifying module configured to specify a cluster group including clusters in content being played back, an access module configured to access a collection of arbitrary cluster groups relevant to the cluster group specified by the group specification module, a search module configured to searching for content specified by a cluster group included in the collection accessed by the access module, and a content presentation module configured to present a result of search by the search module. 
     Embodiments will now be described hereinafter in detail with reference to the accompanying drawings. 
       FIG. 1  is a conceptual diagram illustrating connection among an electronic apparatus  101  as a user (client device), a network connected to the electronic apparatus  101  via a data controller  111 , such as the Internet  11 , and at least one server or a server group (external service mechanism)  1001  positioned on the Internet  11 . The external service mechanism  1001  may also be referred to as a cloud service (program community), for example. The data controller  111  may be embedded in the electronic apparatus  101 . 
     The electronic apparatus  101  is a digital television broadcast receiver (hereinafter referred to as a television set) capable of receiving and playing back a program, for example.  FIG. 1  shows an example in which a USB hard disk device  202 , which records a predetermined program under the control of a recording device  201  or the television set  101 , is connected to the television set  101 . 
     When equipped with a recording function, the television set  101  is capable of creating a list of recorded programs stored in the television set  101 , recording device  201 , or USB hard disk device  202 . When not equipped with a recording function, the television set  101  is equipped with a home server function in which the television set  101  functions as a database capable of creating a list of recorded programs stored in the recording device  201  or USB hard disk device  202 . 
     The television set  101  may be any device equipped with a user interface, a wireless or wired communication function (short-distance wireless communications via Bluetooth [registered trademark], for example, communications with the outside via a network [the Internet], or the like), a function of receiving a broadcast, a processing function of processing a received broadcast, i.e., a program, a program output function of outputting the program, a storage (recording) function, or the like. Examples of such devices include a personal computer (PC) equipped with a function of receiving a broadcast, a video display device (monitor device) connected to a video recording device (recording device) including a broadcast receiving device, and a portable device equipped with a broadcast receiving function. The term broadcast includes a broadcast that is provided by a broadcaster (broadcast station) as electromagnetic waves propagating through space, and a broadcast that is distributed by a distributor via a cable or a network such as an Internet Protocol (IP) network. A broadcast includes video, speech, and/or music, for example, and provides a program of a certain time (broadcast time) unit in succession or for a predetermined period (of time). A program will also be referred to as content or a stream. The term video includes a moving image, a still image, text (information represented by characters and symbols represented by coded strings), and an arbitrary combination thereof. 
     The external service mechanism  1001  includes a history server (preference information database) 1, EPG server (database) 2, calendar/channel data server (database) 3, relevant program database (server) 4, data provision server (metadata server) 5, and the like. The history server 1, relevant program database 4, and EPG server 2 are managed by the manufacturer (maker) of the television set  101  or a contractor therefor, or prepared and managed by a company independent from the manufacturer of the television set  101 , for example. The data provision server 5, on the other hand, is usually prepared and managed by a metadata creation mechanism (metadata creation company), for example. 
     The history server 1 stores the user&#39;s preferences, for example, information on programs viewed by the user or recorded programs played back by the user, i.e., a history (log data) and the like. The history server 1 obtains information such as an access history of sites accessed by the television set  101 , information on payment for goods purchased on an accessed site, purchased tickets of a concert or the like, and accommodation arrangement, for example. Data transfer between the television set  101  and the history server 1, i.e., supplying (transmitting) information from the television set  101  to the history server 1 and acquiring (receiving) information by the television set  101  from the history server 1, is managed by the data controller  111 . 
     The data controller  111  manages data transfer between the television set  101  and external service mechanism  1001 , i.e., each of the history server 1, EPG server 2, calendar/channel data server 3, relevant program database 4, and data provision server 5. The data controller  111  further performs a recommendation process (has a function as a recommendation processing engine [RE]) in which the data controller  111  receives recommendation from the user and processes the received recommendation as preference information. 
     The data controller  111  further controls connection and data transfer between an arbitrary site (web page) positioned on the Internet  11  and the television set (user)  101 . The data controller  111  may be positioned between the television set  101  and the network (Internet  11 ), or positioned inside the cloud service  1001  (arbitrary position between external service mechanisms 1, . . . , N). 
     The EPG server 2 obtains information on a program received by the television set (user)  101  independently from direct reception by the television set  101 , generates a database on the basis of the obtained information, and stores the generated database. 
     The calendar/channel data server (database) 3 stores the broadcast data and time of a program scheduled for recording by the user, the name of a regional broadcast station (channel) on which a broadcast can be received (viewed/recorded) by the user, or a channel name provided by a distributor, the broadcast schedule of other stations, the broadcast time of which partially overlaps with the broadcast time of the program scheduled for recording by the user, rebroadcast information (including a program scheduled for recording by the user), and the like. 
     When the user sends a predetermined operation input (control instruction) to the television set  101  via a remote control unit (operation input part/portable device) while the user is viewing a program or playing back a recorded program, the relevant program database 4 extracts programs and data relevant to the program viewed by the user or the program scheduled by the user that is stored in the history server 1 on the basis of a variety of types of data provided by the data provision server 5 and stored in the relevant program database 4, as will be described later. 
     The data provision server 5 stores a variety of types of information relevant to the above-described programs, i.e., information that is prepared and managed by a metadata creation mechanism (maker) that handles metadata and can be extracted as a keyword received from the user (television set)  101  or the history server 1, or the user&#39;s preferences stored in the history server 1, for example, program information on the program viewed by the user or the program scheduled for recording by the user, a “keyword” included in the program, or information registered by the user. 
     The television set  101  stores a cloud application (HTML/JS/CSS), an example of which is shown in  FIG. 2 , as firmware of the CPU (processor)  121  included in the television set  101 , in order to access the Internet  11  via the data controller  111 . The cloud application may be acquired as an application that can be operated by the CPU  121 , or stored in a storage medium or the like in advance. 
       FIG. 2  illustrates an overview of the cloud application (HTML/JS/CSS). 
     The cloud application (HTML/JS/CSS)  103  includes “Controller”  104  which manages processing of a key event (core event), for example, “View”  105  which manages the screen display, “model”  106  which manages information acquisition from an arbitrary server (external service mechanism  1001 ) 1, . . . , N connected via DTVMW (path to and from a browser [Internet  11 ]) or the Internet  11  and operation of the television set  101 , and the like. The television set  101  further includes: a cloud module (CESI)  107  configured to transfer data to and from the history server 1, EPG server 2, and relevant program database 4 via a network, i.e., extract a recorded program containing information that matches information relevant to information featured in the program currently being viewed or the recorded program currently being played back by the user by referring to information stored in the data provision server 5; a data processing (record and playback) module  108  configured to record and play back a program, search for a program, a scene, or a keyword (product), and the like; an operation input part (remote control reception unit)  109  configured to receive an instruction input from an operator (user), and the like. The operation input part  109  may be a portable device equipped with a predetermined application (software) such that an operation of the television set  101  can be controlled, for example, such as a tablet device or a multi-function communication device (smartphone). 
     The television set  101  transmits the IP address of the television set  101 , preference information, information featured in the program being viewed or the recorded program being played back, and the like to the relevant program database 4 and history server 1 via the data controller  111  and the Internet  11 . 
     As the examples in  FIGS. 4A to 4D  show, the relevant program database 4 acquires metadata stored in a metadata creation company, i.e., the data provision server 5, extracts a recorded program containing information matching information featured on the program currently being viewed or the recorded program being played back by the user on the television set  101  or information relevant to the program, and provides the television set  101  with information on the extracted program. The relevant program database 4 reflects the user&#39;s preferences specified by a recommendation process. Extraction of a program (scene) can be performed such that a variety of scenes included in the program, for example, a program in which the group “SAB” or members Miss “BCD”, Miss “EFG”, or Miss “HIJ” of the group individually appears, can be extracted. In this case, the program (scene) of the group “SAB” can be extracted by either including or excluding “SA” or “AB”. When the group “SAB” is set as a keyword, however, the inclusion of “SA” or “AB” reduces the failure of extraction, but also increases the extraction of “ABx” and “xSA” (where x is an arbitrary character, number, symbol, or the like), which is not necessarily highly relevant to “SAB”, as noise. In order to reduce the extraction of noise, it is important to set exceptional conditions, which, however, requires knowledge and time and trouble. The keyword and genre used in specification of a scene included in a program and the above-described “SAB”, Miss “BCD”, Miss “EFG”, Miss “HIJ”, “ABx”, and “xSB” will be referred to as [clusters] in a community which will be described later. The community will also be referred to as a [cluster group]. 
       FIG. 3  illustrates an exemplary configuration of the relevant program database according to the embodiment. 
     A description will now be given on functions provided by the relevant program database 4. In the description that will be given below, by interposing the data controller  111  during transfer of data between the television set (user/client device)  101  and relevant program database 4 or metadata server (data provision server) 5, each of information provided (transmitted) by the user (television set  101 ) to the data provision server 5 and information provided by the data provision server 5 to the user (received by the user), a corresponding keyword, and the like can be accumulated in the history server 1. 
     &lt;Command (WebAPI) Processing&gt; 
     The relevant program database 4 acquires a variety of types of data, which will be described below, from the metadata server 5, and provides a recorded program list server stored in the television set  101  (may be stored in a recording device  201  or a USB hard disk  202 ) with the acquired data. Examples of the variety of types of data include “scene information”, “relevant program data”, and the like. 
     &lt;Acquisition of “Scene Information” List&gt; 
     A “scene information” list of a program matching conditions specified by the user (television set)  101  is acquired. When a plurality of “scene information” lists of the program matching the specified conditions exist, all the lists are acquired. When a “scene information” list that matches the conditions does not exist, a notification is made to that effect. 
     &lt;Acquisition of “Program List” Including “Scene Information” List&gt; 
     A “program list”, which gives a list of programs including a “scene information” list that matches the conditions specified by the user (television set)  101 , is acquired. 
     &lt;Acquisition of List of &lt;Scene Information&gt; Lists&gt; 
     A “list of scene information lists”, which is a list of “scene information” lists registered in a program specified by the user (television set)  101  is acquired. 
     &lt;Acquisition of Scene Information List (ID Specification)&gt; 
     A list of “scene information” of a specified ID is acquired from the “list of scene information lists”. 
     &lt;Search for “Scene Information”&gt; 
     A “scene information list” containing “scene information” that matches specified search conditions is acquired. In the search conditions, an arbitrary keyword entered by the user can be specified. 
     &lt;Acquisition of “Scene Information” Based on User&#39;s Preferences&gt; 
     Metadata or the like matching “scene information”, i.e., a “keyword” based on the user&#39;s preferences managed by the history server 1 is acquired. 
     &lt;Metadata Acquisition Process&gt; 
     Metadata provided by the metadata server 5 is acquired. 
     The metadata provided by the metadata server 5 is acquired using WebAPI provided by the metadata server 5. 
     &lt;“Scene Information” Generation and Transmission Process&gt; 
     “Scene information” is generated or extracted as “relevant program data” on the basis of metadata acquired from the metadata server 5, and the “scene information” is transmitted to the television set  101 . 
     A description will be given below on a process to be performed during generation of “scene information”. 
     (A) Assignment of Program Information 
     The television set  101  transmits the following: 
     (a) Program name (or identification information such as a program ID); 
     (b) Program broadcast date and time; and 
     (c) Channel number 
     The metadata server 5 searches a database in the metadata server 5 on the basis of the (a) program name, (b) program broadcast date and time, and (c) channel number received from the television set  101 , and when an appropriate program in which one or more items of “scene information” are registered exists, the one or more items of “scene information” of the program are generated, and then transmitted to the television set  101 . 
     When a plurality of appropriate programs exist, the metadata server 5 transmits all the candidates to the television set  101 . 
     When no appropriate programs exist, the metadata server 5 transmits a notification to the television set  101  to that effect. That is, the television set  101  transmits identification information (the program name, program broadcast date, channel number, and the like) of the program to the metadata server 5, and receives “scene information” corresponding to a scene of the program from the metadata server 5. 
     (B) Search for “Scene Information” 
     The database in the metadata server 5 is searched for metadata information matching the search conditions received by the television set  101 , and a “scene information” list containing the appropriate metadata information is transmitted to the television set  101 . The metadata to be searched for includes program broadcast history data, product data, shop data, and TV and broadcast history data, and the like shown in  FIGS. 4A ,  4 B,  4 C, and  4 D. 
     (C) Generation of Scene Information 
     “Scene information” is generated by associating the broadcast history data, the product data, the shop data, and the TV ad broadcast history data stored in the database of the metadata server 5 with the “scene information”. There are cases where product information and shop information do not exist in one item of “scene information”. There are also cases where a plurality of items of product data and shop data are associated with one item of “scene information”. 
     (D) Extraction of Relevant Program Data 
     The relevant program database 4 sets the search conditions such that information matching information relevant to information featured in the program currently being viewed or the recorded program being played back by the user on the television set  101  can be extracted from a recorded program recorded and stored by the recording device  201  (or the USB hard disk device  202  [television set  101 ]) from the database in the metadata server 5. 
     That is, the relevant program database 4 extracts metadata that is relevant to or can be associated with information on recorded programs stored in the television set  101 , recording device  201 , or USB hard disk device  202  as a recorded program list and information on the program currently being played back by the user from the metadata server 5, and generates a database on the basis of the metadata and stores the database such that the user (television set  101 ) can access the database. 
     In a state in which the television set  101  (user), recording device (recorded program list database/home server)  201 , and data controller  111  described above are connected to the cloud service  1001  (or connected to the cloud service  1001  after start of viewing or playback), by positioning a cursor on an “automatic recording” button  501  on a cloud menu [Home] screen display shown in  FIG. 5A  of a program currently being broadcast and viewed or a cloud menu [My Page] screen display shown in  FIG. 5B  and pressing an enter button (of a remote control device), or causing a screen display of a program being played back (viewed) shown in  FIG. 5C  to display a menu screen by operating a remote control device, selecting “automatic recording”, and pressing the enter button, an “automatic recording community” screen display  511  shown in  FIG. 5D  is displayed. “Automatic recording”, which uses the “automatic recording community”, can be achieved by registration by the user in a “cloud service (TimeOn)” (subscription to “program community” by the user), which will be described below. 
     The cloud service (TimeOn) includes services that allow the user to use an “automatic recording community” and participate in (register in) a “program community”, create (and change and add) a “program community” as a master, acquire [points] added for creation, change, and addition of the “program community”, set “automatic recording” by registering in the “program community”, and the like, as shown in  FIG. 5D . The cloud service (TimeOn) also allows the user to perform “highlight scene playback”, for example, based on a “highlight scene playback” screen display shown in  FIG. 5H . 
     By selecting an arbitrary program from the “[Program Community ([cluster group])” screen display shown in  FIG. 5D  and turning on “Register/automatic Recording” button (turning on the enter button by positioning a cursor on a bar display), settings for automatic recording (recording of programs in a list made by the community by registering in “automatic recording community ([cluster group])”) are completed. It is also possible to make settings on an upper limit on the recording time per day from a setting screen for setting the upper limit, as shown in  FIG. 5E , or to make settings on the range of channels to be recorded (regular [terrestrial] broadcasting/BS broadcasting/CS broadcasting) from a setting screen for setting the range of channels, as shown in  FIG. 5F . The upper limit setting screen display shown in  FIG. 5E  and the channel range setting screen display shown in  FIG. 5F  can be arbitrarily displayed in response to a request for a setting screen display at the time of user registration in the “cloud service (TimeOn)” (subscription by the user to “program community ([cluster group])”) or a screen display (setting screen display) at predetermined timing made in accordance with a remote control operation by the user. 
     The programs recorded using the “automatic recording community ([cluster group])”, i.e., the “automatically recorded” programs are displayed on the television set  101  as an “automatic recording list” shown in  FIG. 5G  (as described above). The “automatically recorded” programs can be linked with (referred to from) a “highlight scene playback” screen display ( FIG. 5H ), which will be described later. 
       FIG. 6  illustrates an exemplary procedure of registration (setting) in an “automatic recording community ([cluster group])”, which achieves “automatic recording”. 
     The procedure starts by uploading a log of the “program name”, “genre”, “personal name (performer&#39;s name)”, “keyword”, and the like of the program being viewed. The program being viewed may be either a program currently being broadcast (on the air) or a recorded program (S 61 ). 
     When the user selects “Cloud menu service” by a remote control operation, a “program community” relevant to the program being viewed is displayed (S 62 ). 
     When an “automatic recording service” is selected from the “program community” in the “cloud menu service” screen display, a list of programs is displayed as candidates for “automatic recording”. In this case, the latest list of programs included in the selected [program community ([cluster group]) is displayed as the list of programs as candidates for “automatic recording” (S 63 ). 
     The programs displayed as candidates for “automatic recording” in the list are set (scheduled) as programs for “automatic recording” in a target television set. 
     For example, when the user wants to record all of a program community ([cluster group]) [A] for programs in which Mr. A appears, a program community ([cluster group]) [B] for programs in which Mr. B appears, and a drama ranking community ([cluster group]) [C], and there are two television sets that can be used for recording, the communities [A] and [C] can be set to “automatic recording” in the first television set [TV1], and the community [B] can be set to “automatic recording” in the second television set [TV2], for example. 
       FIGS. 7A to 7C  illustrate an overview of settings necessary for achieving “automatic recording”. 
     Basically, “automatic recording” can be set by [Account creation (for the first time only)] and [Log in] (S7A1) shown in  FIG. 7A , registration in a “program community” (S7A2), and setting of “automatic recording” (S7A3). 
       FIG. 7B  illustrates an example in which user A performs [Account creation] in the first television set [TV1], registers in a “golf” program community, for example, and sets “automatic recording”. 
     It is thereby possible for the cloud service server to recognize (detect) that user A has registered in (subscribed to) the “golf” program community, and turn on (set) the “automatic recording” in the first television set [TV1]. 
       FIG. 7C  illustrates a case where user A logs in to the second television set [TV2] with the account same as used in the first television set [TV1] and registers in a program community ([cluster group]), but “automatic recording” is not set. 
     In this case, the second television set [TV2] is capable of displaying the community registered in the first television set [TV1] and turning on (setting) “automatic recording” in the second television set [TV2]. 
       FIGS. 8(   a ) to  8 ( d ) illustrate an example of setting “automatic recording” in a plurality of television sets. 
     Basically, “automatic recording” can be set by [Account creation] (S8A1), [Log in] (S8A2), registration in “program community ([cluster group])” (S8A3), and “automatic recording” setting (S8A4) shown in  FIG. 8(   a ). The [account creation] (S8A1) is required only for the first time, and the procedure usually starts from [Log in] (S8A2). 
       FIG. 8(   b ) illustrates an example in which user A (Taro Tokyo) performs [Account creation] in the first television set [TV (A)] (S8B1), performs [Log in] with the created account (S8B2), registers in a “golf” program community ([cluster group]) (S8B3), for example, and sets “automatic recording” from registration settings of the program community on the first television set [TV (A)] (S8B4). 
       FIG. 8(   c ) illustrates a case where user A logs in to the second television set [TV (B)] with the same account as used in the first television set [TV (A)] (S8C2) and the program community registered in the first television set [TV (A)] is displayed as the program community (S8C3). Since the account has already been created in the first television set [TV (A)], creation of a new account is not required (S8C1). 
     Thereby, “automatic recording” is set from registration settings of the program community on the second television set [TV (B)]. That is, the second television set [TV (B)] is capable of displaying the community already registered in the first television set [TV (A)] and turning on (setting) “automatic recording” of the second television set [TV (B)] (S8C4). 
       FIG. 8(   d ) illustrates a case where user A logs in to the third television set [TV (C)] with the same account as used in the first television set [TV (A)] (S8D2), and the program community registered in the first television set [TV (A)] is displayed as the program community (S8D3). Since the account has already been created in the first television set [TV (A)], creation of a new account is not required (S8D1). 
     Thereby, “automatic recording” is set from the program community registration settings on the third television set [TV (C)]. That is, the third television set [TV (C)] is capable of displaying the community registered in the first television set [TV (A)] and turning on (setting) “automatic recording” of the third television set [TV (C)] (S8D4). 
     That is, as shown in  FIGS. 8(   a ) to  8 ( d ), when the user logs in to a plurality of television sets with the same account, connection is automatically made to a registered [program community ([cluster group])]. That is, one “program community” can be registered in a plurality of television sets. In this case, “automatic recording” of the “program community” can be performed only on a television set in which “Register” is set. In other words, in order to achieve “automatic recording” in a plurality of television sets, the [program community] should be registered in each of the television sets. 
       FIGS. 9A and 9B  illustrate an example of [clusters] and a [cluster group] used in “automatic recording”, which uses a [program community]. 
       FIG. 9A  illustrates an example of basic data ([clusters] and a [cluster group]) of a program 1. 
     As shown in  FIG. 9A , the program name, broadcast channel, broadcast time range, and the like, which are unique to the program exist as a variety of [clusters] of the program 1. Examples of the [clusters] also include information on the presenter, performer, co-star [1], co-star [2], . . . , and co-star [n] (where n is an arbitrary number), and television advertisement (TV ad) information (such as the sponsor [company name] and product) of the program. Even with a program having the same program name, the information such as the presenter, performer, co-star [1], co-star [2], . . . , and co-star [n], and the TV ad information may be changed according to factors such as the broadcast timing (every week/specific date and time [XX Spectacular]/rerun program). 
     The basic data ([clusters]), on the other hand, includes non-changing data. For example, in a case where the program 1 is a drama program, information such as the writer, director, scriptwriter, and genre of the program is such basic data. 
     Examples of such basic data further includes information as to whether the program 1 being broadcast is Episode 1 or Episode 2, for example, the performer, the scenery (photography location), a vehicle (maker) that appears in the program, the costume worn (maker) by the performer, the program music, and the composer, for example. Further, combined basic data, formed of a combination of the above-described individual items of basic data, also exist. 
     Such data may accompany information (program identifying information) on other programs containing the same basic data. 
     When the program 1 is a music program, and when at least one (group) of the performers belongs to a group and an independent performance time is allocated to at least one of the members of the group (members of the group are performers [co-stars]) too, for example, if the group “SAB” and the members of the group Miss “BCD”, Miss “EFG”, and Miss “HIJ” individually appear on the (same) program, [clusters] exist for each of the group and the members. For example, when Miss “BCD” and Miss “EFG” form another group, the group is identified as a further independent [cluster]. Even when the group “SAB” does not appear and only Miss “BCD” and Miss “HIJ” appear, Miss “BCD” and Miss “HIJ” are identified as independent [clusters]. A collection (group) of one or more [clusters] can be referred to as a [cluster group]. 
     Sorting or classification (grouping) of a variety of types of data ([clusters]) is presented by way of illustration in  FIG. 9A , and is not necessarily limited to the illustrated system. For example, link information (or [clusters] grouping regulations) may be described such that all the files are formed as an integral data file and relevant data is linked between relevant data items ([clusters]). When a [cluster group] including a special [cluster] that should be “always included (never excluded)” is created, for example, the [clusters] grouping regulations (link information) are efficient for preventing lack of such a special [cluster]. The [cluster] grouping regulations are also useful for grouping in which the above-described group “SAB” is excluded and only Miss “BCD”, who is a member of the group, is extracted. 
       FIG. 9B  illustrates an example of association routes, i.e., elements of grouping when [cluster groups] are created using the above-described variety of types of data files when a viewer and another viewer are associated (grouped). 
     For example, an association route ([cluster group]) G1 represents a group in which a part or all of basic data 1 of a program 1 viewed by a viewer 1 is the same as a part or all of basic data of a program 5 viewed by a viewer 5. 
     A route ([cluster group]) G2 represents a group in which a part or all of basic data 1 of a program 3 viewed by a viewer 3 is the same as a part or all of the basic data of the program 5 viewed by the viewer 5. A route ([cluster group]) G3 illustrates that a program 2 viewed by a viewer 2 and a program 5n viewed by the viewer 5 are the same. Similarly, a route ([cluster group]) G4 illustrates that the program 3 viewed by the viewer 3 and a program 4n viewed by the viewer 4 are the same. 
     The association routes ([cluster groups]), i.e., grouping at the time of creation of [cluster groups], can be achieved by information stored in a recorded program list server stored in the relevant program database 4, history server 1, and television set  101 , and registration (participation) in an “automatic recording community ([cluster group])”, for example. 
       FIG. 10A  illustrates an example of [clusters] and [cluster groups], i.e., basic information ([clusters]) relevant to a program and [cluster groups], each formed by associating individual [clusters] of the program or other programs with one another. 
     As shown in  FIGS. 9A and 9B , each program includes basic data, i.e., a variety of [clusters]. Accordingly, the program 1, program 2, program 3, and program 4, including AD1 ([cluster]), for example, which exists as basic data of the program 1, can be associated with one another. The association of the programs 1, 2, 3, and 4 shown in  FIG. 10A  will be referred to as a [cluster group] CG11, for example. The above-described [cluster group] CG11 can also be referred to as a [program community]. 
     The program 4 can be removed from the [cluster group] CG11 by a combination with a [cluster group ([program community]) CG21, which is centered of the performer [2], for example. It is also possible to search for programs 11 and 12, for example, on the basis of a combination with a [cluster group] CG101 defined by a [cluster group] CG12 of a program in which the performer [1] appears in a program 1 and a [cluster group] CG121 in which a genre [1] is set as a [cluster], with a central focus on the performer [1] who appears in the program 1. 
     In the example of  FIG. 10A , when the two performers [1] and [2] are the members of the group SAB, by setting another member of the group SAB, for example, the member [41] as a [cluster], the programs 51 and 52 in which the member [41] appears can be searched for on the basis of the [cluster group] CG41, into which programs in which the member [41] appears are grouped. Further, the programs 21 and 22 ([cluster group] CG122), in which a performer [21] appears, can be searched for on the basis of the [cluster group] which sets the program 51, in which the member [41] appears, as a [cluster]. Thereby, association between the [cluster group] CG121 including the genre [1] and performer [21] is found. It is thus possible to find that the performer [21] appears in a plurality of programs of the genre [1], which cannot be found by a combination of the performer [1], performer [2], and AD1. At the same time, it becomes possible to associate performer [2] with performer [21] by the genre [1], and to ascertain existence of the program 31 in which performer [2] and performer [21] appear. 
     In the example of  FIG. 10A , when a program 101, which is a program on another channel (station), for example, is extracted by a combination of a [cluster group] CG21, which sets the performer [2] as a [cluster], and a [cluster group] CG31, which sets a member [31] as a [cluster], the program 4, which has been removed using the [cluster group] CG21, which sets performer 2 as a [cluster], from the [cluster group] CG11 which sets AD1 of the program in which performer 1 appears as a [cluster], can be arrived at from the [cluster group] 111 which sets the performer [11] as a [cluster]. 
     Thus, according to formation of [cluster groups] (combination of [clusters]), two or more approaches (search methods) can be taken for one program. At the same time, since the program 52 can be searched for on the basis of the [cluster group] CG21, in which the performer [2] is set as a [cluster], the [cluster group] CG41, in which the member [41] of the group SAB is set as a [cluster], can be found. 
     That is, it becomes easy for the user to find, from [clusters (basic data)] of a program in which at least one member of the group SAB appears, other programs in which other members of the group appear as solo or in group of two or more, by registering (participating) in a [cluster group (program community)]. This indicates that other programs in which the group SAB does not appear but at least one of the members of the group appears can be searched for on the basis of the [clusters (basic data)] of a program in which anyone of the group SAB appears. 
     By registering (participating) in the [program community (cluster group)], selecting an arbitrary [cluster], and tracing a [cluster group] to which the [cluster] belongs, inputting a keyword and a variety of settings as narrow-down conditions, for example, becomes essentially unnecessary. 
     Thus, a [program community] can be provided for each of a [cluster group] centered of an arbitrary [cluster], another [cluster group] centered of another [cluster], yet another [cluster group] which shares one or more common [clusters] of the [cluster group], and the like. 
     By using the program community ([cluster group]), it is possible to prevent extraction of “SA”, “AB”, “ABx”, or “xSA” (where x is an arbitrary character, number, symbol, or the like), for example, which is similar to a program in which the group “SAB” and Miss “BCD”, Miss “EFG”, and Miss “HIJ”, for example, who are the members of the group, appear as solo or in group of two or more, as noise. 
     In this case, by registering in an arbitrary [cluster group], i.e., a [program community], it is possible to view relevant scenes such as “idol highlights” and “gourmet highlights” merely by selecting the “program community”. As a matter of course, when “automatic recording” is set, a relevant program can be automatically recorded. That is, the need of a user who “never wants to miss a program that the user is interested in” can be filled by registering in a [program community] and setting “automatic recording” such that an arbitrary number of programs associated with the registered [program community] are recorded “automatically”. For example, in a “late-night anime” program community, late-night anime programs are recorded one after another, and in a “favorite entertainer” program community, programs in which the entertainer appears are recorded one after another. As a matter of course, when the above-described upper limit is set in relation to a recording capacity, programs are automatically recorded within the range of the upper limit. 
     The need of a user who “tentatively wants to check out popular programs” can be filled by setting “automatic” recording in a [program community] for “popular programs”, “new programs”, and the like and finding an “interesting program and/or genre” which the user has not known, for example, even if the user does not have a favorite program genre or a favorite entertainer in particular. 
     By thus registering in the [program community] including [clusters] or [cluster groups] and setting “automatic recording”, the complicated procedure for scheduled recording of obtaining information on popular programs from rankings on the Internet, features of magazines, conversation with friends, and the like, and then searching for a program from program listings and scheduling the program, for example, can be replaced with a simple recording procedure (of setting automatic recording). 
     Further, the user is not requested, as much as possible, to directly enter information that is to be a target for a program search, for example, keywords such as the name of an entertainer, the name of a group, and appearance information of individual members of the group, and the genre of the program. That is, even when the user wants to record a specific performer, program, or the like, inputting characters and settings specifying whether to “include” or “exclude” something, for example, will be unnecessary merely by searching for the [program community]. 
     Thereby, when the group “SAB” and Miss “BCD”, Miss “EFG”, and Miss “HIJ”, who are members of the group individually appear on the (same) program, or when the group “SAB” does not appear and only Miss “EFG” and Miss “HIJ” appear, for example, the program can be easily recorded by “automatic recording”. In this case, when the group “SAB” is set as a keyword, since the [program community] does not include “ABx”, “xSA”, or the like, which is less relevant to the group “SAB”, it is possible to greatly reduce the inclusion of noise, i.e., programs in which an unintended performer appears. 
     Thus, according to the present program recommendation system and program recommendation method, by registering (participating) in a [cluster group], i.e., a [program community], a number of unspecified programs can be easily associated with one another using [clusters], each becomes a core of the [cluster group]. 
     That is, by using the [cluster group], i.e., the [program community], programs on different centers can be associated with one another from a [cluster] included in one program as a starting point, and a state of association between the programs can be obtained. 
     In other words, in the present program recommendation system and program recommendation method, basic data ([clusters]) representing a variety of attributes relating to a program is defined in a [cluster group], i.e., a [program community], and by arbitrarily combining [clusters], which are basic data of a plurality of programs according to the user&#39;s interests or preferences (selecting a combination presented by the system), the user is capable of recording (scheduling) and viewing a desired program easily, without the need to enter a keyword or set a variety of narrow-down conditions, for example, practically. 
     The [clusters] and [cluster groups], i.e., the [program communities], can be edited (modified) by a user on an individual basis in a hardware configuration shown in  FIGS. 30 to 46 . Further, an arbitrary user can invite other users to a [cluster group] created by the user. Further, an arbitrary user can share a [cluster group] created by another user. 
     That is, while a program is being viewed or (a recorded program is) being played back by an arbitrary television set registered in advance, by transmitting meta-information of the program from the television set to the server (relevant program database), a [program community ([cluster group]) is provided to the television set  101  as information relevant to the program searched for by the server. The television set  101  displays an arbitrary number of cluster groups (program communities) which have been received (provided by the server). 
     By selecting an arbitrary [program community] from among the displayed [program communities ([cluster groups])], the user is capable of automatically recording an arbitrary program associated with the [program community] (“automatic recording”). 
     Each of the cluster groups ([program communities]) has peculiar search conditions. Programs, scenes, video on demand (VOD), television advertisements (TV ads), event information, and the like associated on the basis of the search conditions are searched for and listed up. 
     The search conditions take into account [OR] conditions, [AND] conditions, exceptional conditions, relevant keywords, and the like, of a plurality of keywords, as well as simple keyword search conditions. 
     Participation and registration in the cluster group ([program community]) allows participants to perform communications with one another, and to perform communications with the owner of the cluster group, and the like. It is thereby possible to view automatic recording, scenes, VOD, TV ads, event information, and the like of listed-up programs. 
     Further, a plurality of relevant cluster groups ([program communities]) can be displayed on the basis of a program being viewed or played back in a display order based on similarity with the search program, priority, popularity, genre, and the like (specified by a registered user or set by a master [owner]). 
     The above-described cluster group ([program community]) can be accessed or updated (modified) by an arbitrary user. More specifically, the user (or the master) is capable of performing edits (modifications) on an individual basis in a software configuration in which a screen display and an input screen shown in  FIGS. 11A to 29  are displayed. 
     For example, the user of the television set  101  is capable of selectively performing an operation to access a cluster group ([program community]) or add or modify information such as search conditions peculiar to the cluster group, using a user interface (UI) displayed as a screen display of the television set  101  (as will be described later with reference to  FIGS. 11A to 29 ). 
     Each of the cluster groups contains a plurality of items of meta-information, and can be modified (edited) or added by the user. Points are given to a user who has modified (edited) or added a cluster group. Such points include points compatible with mileage points prepared by an airline and quasi-currency points compatible with points provided according to the amount of purchase (use) for a card issued by a credit card company, a department store, or the like. When an inappropriate content is included in the modification or addition by a user as a result of analysis of the content, the master, for example, is capable of rejecting or deleting the modification. The cluster group modified (edited) or added by a user can be shared with other users. In this case, the users who can share the modified (edited) or added cluster group can be limited to registered users (set by [Friend select] shown in  FIG. 12A ) of the [program community] shown in  FIGS. 11A to 29 , or can be made public such that the modified (edited) or added cluster group is shared by all the users. 
     A display order in which the program communities ([cluster groups]) are displayed shown in  FIGS. 11A to 29  has a profound effect on the program (program community) to be selected by a user. Accordingly, the display order of the program communities is based on a viewing history stored in the history server 1, for example. In contrast, in order to present programs desired by the user, “new arrivals”, “popularity (topicality)”, i.e., “newsworthiness” that affects the viewing trend of other users, such as a match of top teams in sports, and the like need to be taken into consideration, such that the programs can be arbitrarily set (rearranged) by the user. The rearrangement can be performed in a variety of orders, for example, by date (in a chronological or a reverse chronological order), by title, by genre (type), in descending order of the number of bookmarks, and the like. As a matter of course, it is possible to give priority to the special condition to “always include (never exclude)”. A rebroadcast program is usually excluded, but it is also possible to make a setting not to exclude rebroadcast programs for the storage purpose or for a user who has failed to record some of a series of programs. 
       FIG. 10B  illustrates an extension example of a [cluster group]. 
     For example, when a [cluster group (program community)] described with reference to  FIG. 10A  is based on the same program listings, for example, terrestrial digital broadcasting that can be received by a number of television sets  101 , a [cluster group] which sets a member [41] of the group SAB as a [cluster], for example, can exist in content (video) distributed by video-on-demand (VOD), i.e., on a network (provision form 2) or another content provision form (provision form 3) such as BS (transmission using a direct broadcast satellite) and CS (transmission using a communications satellite), for example, as illustrated in  FIG. 10B . 
     Therefore, as shown in  FIG. 10B , a [cluster group] CG41, in which the member [41] of the group SAB, for example, is set as a [cluster], can be mutually associated with CGV111, which is a [cluster group] of a VOD content, for example, and a [cluster group] CGS1101, which sets a CN (broadcast) program [N], for example, as a [cluster] (which are shown on the same axis for the purpose of illustration in  FIG. 10B ). Most of the [program communities] can exist over different content provision forms, as shown in  FIG. 10B . Thereby, it is possible to advise a user who has similar preferences or interests to record or view even a program (program N) in which a specific member (member N) of the group SAB appears and which is broadcast in a late-night time range in a restrictive area. 
     Further, as shown in  FIG. 10B , by linking the [cluster group (program community)] CG41 with CGV111 or CGS1101, which are different content provision forms, the user can arrive at a program (content) that the user has not noticed. 
     That is, it is possible to advise the user to record or view a program or content with high relevance that the user does not notice, or has not noticed on the basis of one [cluster]. 
       FIG. 10C  illustrates an example of development of [cluster groups] from another point of view. 
     A case is assumed where the program 1 featured in the [cluster group (program community)] described with reference to  FIG. 10A  is animation, for example, and one of the voice actors is set as a [cluster] in a [cluster group] CG1011, by way of illustration. In this case, since a [cluster group] CG1012 which sets the writer [1] as a [cluster] and a [cluster group] CG1013 which sets the production company or the director as a [cluster], for example, can exist with respect to the program 1, if another program 1001 that has fewer commonalities as to the genre, sex of the target viewers, and age group of the target viewers can be searched for on the basis of the [cluster group] CG1013 of the production company or the director, it is possible to advise registrants of different [program communities] who are interested in the respective programs to record or view programs that the registrants presumably do not usually view. 
     That is, as shown in  FIG. 10C , it is possible to provide advice regarding a program 1002, the writer, target age group, and target sex of which are different from those of the program 1, on the basis of the [cluster group] CG1013 which sets the director of the program 1 as a [cluster], the [cluster group] CG1011 which sets the voice actor [1] as a [cluster], and the [cluster group] CG1012 which sets the writer [1] as a [cluster]. 
       FIGS. 30 to 46  illustrate an exemplary overview of a system according to the embodiment. 
       FIG. 30  schematically illustrates a conception of a program community service according to the embodiment. 
     As shown in  FIG. 30 , an electronic device, such as a television broadcast receiver (hereinafter referred to as a television set, or simply a TV or a TV set)  101  equipped with a recording function downloads an automatic recording list &lt;Auto Rec List&gt; from a server (such as a cloud service &lt;Cloud Service&gt;)  1001 , and prepares for recording of a program (content) desired by the user. The television set (TV)  101  may be a display device to which a video recorder (or a recording device) is connected. The server  1001  may be formed of either one server device or a plurality of server devices. The display device may be any device capable of displaying moving images and still images, such as a display device connected to a personal computer (PC), for example, or a portable device called a tablet device, for example. Data transfer between the display device and the recording device may be performed in either a wired or wireless manner. 
     The server  1001  stores an automatic recording list created on the basis of information that can be acquired from a social networking service (SNS) which is referred to as a program community &lt;community&gt;, for example, and allows users to share information on content (programs) that the users want to view or record, and information contained in electronic program guides (EPG), such that the user can acquire the automatic recording list. The program community is designed to be created for a specific theme by a user, for example, and a one-on-one program list (list of programs to be recorded or viewed) is set for each program community. In other words, the program community is designed to connect a plurality of users via a program list as a center, and is also designed to allow a plurality of users to share the program list. The recording list may be created manually by a user by adding a program one by one, or a program list that matches search conditions set by a user for a program community may be created. When a user registers in the program community, a program list set in the program community is downloaded into the device used by the user. The device performs a recording process and a reproduction process according to the downloaded program list. In the server  1001 , a plurality of program communities set by the user or the like exist, and a plurality of users are registered in each of the program communities. A user is capable of registering in a plurality of program communities. 
       FIG. 31  illustrates an example of data transfer between the television set and the server (cloud service). 
     As shown in  FIG. 31 , the television set  101  includes an interface part &lt;Cloud App&gt;  103  which controls transfer of data between the television set  101  and the server  1001 , i.e., access to the server  1001 , an information storage part &lt;Native &lt;DTV Native&gt;&gt;  131  which stores an acquired automatic recording list and records content (programs) according to the list, and a central processing unit (CPU; processor)  121 . A non-volatile memory (NVM)  191 , for example, which stores “points”, which will be described later, is connected to the CPU  121 . The NVM  191  may be connected to a data controller  111 , or provided in the server  1001 . 
     The interface part  143  includes an automatic recording user interface &lt;Auto Rec Setting UI&gt;  107  which manages recording settings for automatic recording, a search user interface &lt;Search Set UI&gt;  149  which manages search condition settings for automatic recording, and a program community user interface &lt;Community UI&gt;  145  which controls the both interfaces &lt;activates the both interfaces and manages operation of the both interfaces&gt;, with respect to the program community provided by the server  1001 . 
     The information storage part &lt;Native&gt;  145  includes a data storage part (storage such as a hard disk drive [HDD])  134  configured to store automatic recording data &lt;Auto Rec Data&gt;, schedule information (data &lt;Reserve Data&gt;), and content (program &lt;Record Content&gt;), and a data storage management part &lt;Hard Disk usage&gt;  137 , which manages content stored on the HDDs (storages)  132 ,  133 , and  134 . The schedule information (data &lt;Reserve Data&gt;) is data scheduled for recording set in advance in the television set  101 , and is a list of scheduled programs, for example. The schedule information (data &lt;Reserve Data&gt;) may include scheduled recording set on the basis of automatic recording data, and scheduled recording set by a user operation on the television set  101 . 
     An upload part &lt;Log Upload&gt;  135  transmits schedule information &lt;Reserve Data&gt; stored in the data storage part  132  to the server  1001 . A list acquisition part &lt;Get Auto Rec List&gt;  137  acquires the automatic recording data (automatic recording list &lt;Auto Rec Data&gt;)  1015  from the server  1001 . 
     The data storage part  132  stores automatic recording data (automatic recording list &lt;Auto Rec Data&gt;) acquired by the list acquisition part &lt;Get Auto Rec List&gt;  136 . The data storage management part &lt;Hard Disk usage&gt;  137  stores restrictive conditions for recording set in the television set  101 . The restrictive conditions refer to restrictions on recording, such as a channel from which a recording can be made, a time range in which recording can be made, and the amount of time per day for which recording can be made. The television set  101  records programs shown in the list on the basis of the acquired automatic recording list. The television set  101  may record a program included in an automatic recording list and given a higher priority preferentially when the remaining capacity of the HDD (data storage parts  132 ,  133 , and  134 ) is less than a predetermined value. An order of priority for programs to be recorded is determined on the basis of an order of priority for channels carrying the programs, an order of priority for time ranges of the programs, an order of priority for program communities to which the programs belong, an order of priority for users who are registered in the program communities, or the like. 
     The operation of each of the above-described parts (blocks), interfaces, and the like in the television set  101  is controlled by a central processing unit (CPU)  121 . 
     The server  1001  includes an automatic recording setting part &lt;Auto Rec Setting(s)&gt;  1011 , a search condition storage part &lt;Search Set&gt;  1012 , a search part &lt;Search Engine&gt;  1013 , an EPG data storage part &lt;Nimbus EPG&gt;  1005 , a calendar database part &lt;Calendar Database&gt;  1007 , an upload reception part &lt;Log Collector&gt;  1014 , and an automatic recording list creation part &lt;Auto Rec List&gt;  1015 . Each element of the server  1001  is controlled by an MPU (main control block)  1101 , for example. 
     The automatic recording setting part &lt;Auto Rec setting(s)&gt;  1011  makes automatic recording settings according to recording setting (Auto Rec Setting&gt; information, which is an input from the automatic recording user interface  107  of the television set  101  and search condition &lt;Search Set&gt; information, which is an input from the search user interface  149  of the television set  101 , and stores the automatic recording settings. 
     The search condition storage part &lt;Search Set(s)&gt;  1012  receives the search condition &lt;Search Set&gt; information from the television set  101 , and provides the automatic recording setting part and the search part with the received information. 
     The search part &lt;Search Engine&gt;  1013  receives the search conditions from the search condition storage part  1012  and the schedule information &lt;Reserve Data&gt; from the upload part &lt;Log Upload&gt;  135 , and searches for content for automatic recording by referring to program information stored in the EPG data storage part  1005  and date and time information managed by the calendar database part  1007 . The search part  1013  provides the automatic recording list generation (storage) part &lt;Auto Rec List(s)&gt;  1015  with the searched result via the upload reception part &lt;Log Collector&gt;  1014 , such that the searched result can be used as recommended data &lt;Auto Rec Data&gt; for automatic recording. That is, the search part  1013  searches for a program on the basis of search conditions set by a master, for example, for each program community, and provides the automatic recording list generation (storage) part &lt;Auto Rec List(s)&gt;  1015  with the program list obtained by the search. The upload reception part &lt;Log Collector&gt;  1014  collects schedule information &lt;Reserve Data&gt; from the television set  101 . The upload reception part &lt;Log Collector&gt;  1014  may acquire schedule information on a user basis, for example. That is, when a user uses a plurality of devices, for example, a television set equipped with a video recorder or a recording function, such as the television set  101 , a recording device capable of recording and playing back content, and the like, schedule information may be obtained from the plurality of devices associated with (linked with) the user. In this case, the server  1001  may store a list indicating correspondence between users and devices used by the users. When one recording device is used by a plurality of users, the upload reception part &lt;Log Collector&gt;  1014  may further acquire schedule information on scheduled recording set by each of the plurality of users. The upload reception part &lt;Log Collector&gt;  1014  may further acquire information on scheduled viewing set in the television set  101 . The upload reception part &lt;Log Collector&gt;  1014  may further acquire information on restrictive conditions set by the television set  101 . The restrictive conditions refer to restrictions on recording set in the television set  101 , such as a channel on which recording can be made, a time range in which recording can be made, and the amount of time per day for which recording can be made. 
     The automatic recording list storage (creation) part  1015  stores the search result by the search part  1013  such that the list acquisition part (television set  101 ) can acquire the search result as recommended data for automatic recording. That is, the automatic recording list storage (creation) part  1015  makes the automatic recording list set for each program community public to a network, such that the automatic recording list can be accessed by the interface part &lt;Cloud App (Front-end)&gt;  145 . The automatic recording list storage creation part  1015  prepares, for each television set  101 , an automatic recording list, which is obtained by removing programs overlapping with programs indicated by schedule information acquired by the upload reception part &lt;Log Collector&gt;  1014  from the programs included in the automatic recording list obtained by search of the search part  1013 . From the schedule information, the automatic recording list creation part  1015  may remove only programs indicated by information on scheduled recording, or may remove programs indicated by information on scheduled recording and programs indicated by information on scheduled viewing. Further, the automatic recording list creation part  1015  may create an automatic recording list in which programs in the automatic recording list are narrowed down on the basis of the restrictive conditions set in the television set  101 . 
     The automatic recording list storage creation part  1015  transmits the list according to a request from the television set  101  (the television set  101  downloads an automatic recording list stored in the list storage creation part  1015  according to a download request from the television set  101 ). That is, the server device  1001  is equipped with a function of making the automatic recording list obtained as a search result by the search part  1013  public and a function of transmitting an automatic recording list obtained by arranging the recording list for each television set  101  to the television set  101  (storing the automatic recording list such that the television set or the recording device can download the automatic recording list). 
     In  FIG. 38 , one recording (video recorder) device (an HDD, recorder, or television set) is shown, but when more than one recording devices (HDDs and/or television sets) are provided, the server  1001  is capable of preparing recommended data &lt;Auto Rec Data&gt; for automatic recording in each recording device. That is, when a plurality of user accounts are set for a television set  101  (recording device) and the plurality of accounts (users) are registered in different program communities, the automatic recording list creation part  1015  may create an automatic recording list obtained by compiling an automatic recording list of each of the program communities, and transmit the complied automatic recording list to the television set  101  (the automatic recording list is stored such that the television set or recording device can download the automatic recording list). In this case, the automatic recording list creation part  1015  may acquire schedule information from a plurality of devices (television sets equipped with recording devices and/or a video recording function) used by each of the plurality of users, and create an automatic recording list obtained by removing programs overlapping with schedule information from the programs included in the compiled automatic recording list. Therefore, it is also possible to classify recording devices according to the type (whether age restriction is set) and genre &lt;Genre&gt; of content, for example. 
       FIG. 32  illustrates a main configuration of a server (cloud service) that embodies a program community &lt;community&gt;. 
     As shown in  FIG. 32 , the server  1001  includes a database section  1003  including a calendar database part &lt;Calendar Database&gt;  1007  and an automatic recording base part &lt;Auto Rec Database&gt;  1009 . 
     An automatic recording server &lt;Auto Rec Service (Web API)&gt; and an automatic recording control unit &lt;Auto Rec Service (cron job)&gt; included in an external calendar server &lt;XX EC2 (tc-calendar)&gt; are connected to the database section  1003 . 
     A program community service &lt;Community Front-end&gt; is connected to the database section  1003  via the automatic recording service program (application &lt;Auto Rec Service Web API&gt;) in the automatic recording server of the external calendar server. A television set &lt;DTV Native&gt;  101  is also connected to the database section  1003  via an automatic recording communication controller (Auto Rec Comm Protocol &lt;automatic recording communication protocol&gt;) in the automatic recording control unit of the above-described external calendar server. 
     Further, the automatic recording base part &lt;Auto Rec Database&gt;  1009  stores a database for automatic recording by referring to EPG data acquired by an automatic recording detection part &lt;Auto Rec EPG Searcher&gt; from an EPG database part &lt;NIMBUS JP API (Nimbus TV Listing Data)&gt;  1005 ′. 
       FIG. 33  illustrates an example of a configuration of a program community (server) and an automatic recording process &lt;Backend&gt; in the program community &lt;community&gt; service. 
     As shown in  FIG. 33 , the program community (server)  1001  hierarchically includes, for example, a Tc-front server &lt;Tc-front&gt;  1021 , a Tc-back server &lt;Tc-back&gt;  1022 , a TC-bom server &lt;Tc-bom&gt;  1023 , a TC-calendar server &lt;Tc-calendar&gt;  1024 , an EPG database part &lt;NIMBUS JP API (Nimbus TV Listing Data)&gt;  1005 ′, a calendar management part &lt;calendar DAO &lt;RDS/S3/etc&gt;&gt;  1031 , and the like. 
     The front server  1021  sets scheduled automatic recording &lt;Automatic Timer Recording Setting&gt; in the television set  101  and the calendar server  1024 . 
     The calendar server  1024  provides the automatic schedules &lt;get Auto Reservation&gt; of the television set  101  to the bom server  1023 , the EPG database part &lt;NIMBUS JP API (Nimbus TV Listing Data)&gt;  1005 ′, and the calendar management part  1031 . 
     Further, the calendar server  1024  sets a search result of programs (content [programs])&lt;Search Result of Programs&gt;  1054 , an automatic recording list &lt;Auto Rec List&gt;  1015 , event data &lt;Event Data&gt;  1005 ′ such as the start time, end time, broadcast type, channel, and the like of an event specified by EPG or a calendar, i.e., a program corresponding to the search result, scheduled automatic recording &lt;Auto Rec Setting(s)&gt;  1015 , and the like. 
     The bom server  1023  sets a “program community form &lt;Community Configuration&gt;”  1053  and “search conditions &lt;Search Set Setting&gt;”  1021 ′ in the calendar management part  1031 . 
     The back server  1022  sets a “program community members list &lt;Forum Members List&gt;”  1051  and “program community messages &lt;Forum Messages&gt;”  1052  in the calendar management part  1031 . A region of the calendar server  1031  that is accessed by the back server  1022  will be referred to as a region  1034 , a region of the calendar server  1031  that is accessed by the bom server  1023  will be referred to as a region  1032 , and a region of the calendar server  1031  that is accessed by the calendar server  1024  will be referred to as a region  1033 . 
       FIG. 34  illustrates a process of searching for programs to be candidates for automatic recording in the program community &lt;community&gt; service. 
       FIG. 34  schematically shows a screen display displayed on the display part of the television set  101 , a shift of screen displays according to a user input (or setting) on the screen display, and a process (data processing) and a flow of the process in a server (program community) shown in  FIG. 33 . 
     &lt;1&gt; By referring to search conditions &lt;Search Set Setting (N)&gt; entered from the search condition &lt;Search Set&gt; (screen display)  109  via the bom server  1023 , an EPG searcher &lt;EPG Daily Searcher&gt;  1013  searches for candidate programs matching the search conditions from an EPG database part  1005 ′. Television list data stored in the EPG database part  1005 ′ may contain information on all the broadcast programs of all regions of the country. The search conditions are set for each program community, for example. 
     &lt;2&gt; The program list &lt;Search Result of Programs&gt; extracted by the EPG searcher &lt;EPG Daily Searcher&gt;  1013  is channel-adjusted by a first filtering device (Device Channel Filter&gt; as necessary. That is, since there are cases where channels of a program differ according to the region in which the television set  101  receives broadcast signals, the first filtering device changes the channel of the program extracted by the EPG searcher  1013  to a channel appropriate for the region of the television set  101  (in which the television set  101  is positioned). The first filtering device &lt;Device Channel Filter&gt; detects a region to which the television set  101  belongs by referring to a channel list &lt;Channel Number&gt; of the calendar database part  1024  and adjusts the channel. 
     &lt;3&gt; A second filtering device &lt;Device Forum Filter&gt; filters a program to be automatically recoded according to restrictive conditions set in the television set  101 , by referring to automatic recording conditions &lt;Auto Record Setting (N)&gt;  1011  entered via the automatic recording setting &lt;Auto Rec Setting for Forum/Device&gt; (screen display)  107  and priority setting &lt;Forum Priority setting&gt; (screen display)  105 . 
     &lt;4&gt; A third filtering device &lt;User Timer Rec Filter&gt; checks to confirm that the program is in a time range in which scheduled recording has not been made (an event does not exist) and scheduled recording can be made. The third filtering device may add a new program to the program list from the second filtering device &lt;Device Community Filter&gt;. In this case, the server  1001  is equipped with a function of causing a user account to register a program recommended by another user account as a program to be recorded. The third filtering device &lt;Device Forum Filter&gt; adds the recommended program (automatic recording &lt;Auto Rec List&gt;) to the program list. 
     Thereby, the automatic recording list &lt;Auto Rec List&gt; is set in the server  1001  such that the automatic recording list can be used (downloaded) by the television set (recording device)  101 . The television set also checks to confirm that scheduled recording can be made on the basis of master settings &lt;Auto Rec Master Setting for Device&gt;. 
     The television set  101  (TV set or video recorder) downloads the automatic recording list &lt;Auto Rec List&gt; once a day, for example, and performs a recording process according to the automatic recording list &lt;Auto Rec List&gt;. When the HDD capacity is less than a predetermined amount, for example, the television set  101  performs filtering specific to the television set  101  in the automatic recording list &lt;Auto Rec List&gt;, and extracts a program to be recorded from the programs included in the downloaded automatic recording list &lt;Auto Rec List&gt;. 
       FIG. 35  illustrates an exemplary overview of an EPG searcher &lt;EPG Daily Searcher&gt; in the program community &lt;Community&gt; server. 
     As shown in  FIG. 35 , the EPG searcher searches for overlapping programs (candidate channels) in a set recording time &lt;interest&gt;, in one or two sets of search &lt;Search Set (N)&gt;, for example. 
     The EPG searcher searches for a channel according to an order of priority &lt;Priority&gt;. 
     The EPG searcher searches for a program according to a set recording time &lt;interest&gt;. 
     The EPG searcher searches for a program according to a genre &lt;Genre&gt;. 
     The EPG searcher is capable of removing rebroadcast &lt;Re-broadcast&gt; programs from the target for search. 
     Data contained in the EPG is also used for the search. 
     That is, the EPG searcher solves the problem of overlapping of recording time, for example, on the basis of the range of channels described with reference to  FIG. 5E , the amount of recording time per day shown in  FIG. 5F , the above-described order of priority, or the like. 
     More specifically, search sets (search conditions) are set in the EPG searcher according to an access to the Tc-bom server by the EPG searcher, as shown in  FIG. 36  (the EPG searcher acquires search conditions). 
     The EPG searcher searches a Nimbus television list database (EPG database part &lt;NIMBUS JP API (Nimbus TV Listing Data)&gt;) for a program appropriate to an input (setting conditions) on the basis of the acquired search conditions (when an appropriate program exists, the program is stored in a database (predetermined storage region). 
       FIG. 37  illustrates an example of filtering performed by the first filtering device &lt;Device Channel Filter&gt;. 
     For example, in a case where a shared list shared by members of a program community exists, in a non-service area, i.e., in an area where a user who wants to set automatic recording lives but some of the broadcasts, such as programs provided by a broadcast station (distributor) or the like from which broadcasts cannot be received, or programs provided by a broadcaster using satellites, such as BS/CS broadcasts, cannot be received, the scheduled automatic recording of the appropriate program can be not set (not selected) using the channel filter. 
       FIG. 38  illustrates an example of filtering performed by the third filtering device &lt;User Timer Rec Filter&gt;. 
     Hereinafter, a case will be described where the number of at least one of the television sets and the users (program community members) is two or more, and a first user (user A) who has registered a user account in a television set with ID (PDID) 0012, for example, a third user (user C) who has registered a user account in a television set with ID (PDID) 0024, for example, and a second user (user B) who has registered a user account in both of the television sets exist, by way of illustration. The server  1001  determines which of the program communities users A, B, and C are registered in. When users A and B are registered in a program community SSS and users B and C are registered in a program community Golf, and scheduled automatic recording is suggested from the two program communities, the program community SSS and the program community Golf, for example, the server  1001  is capable of sorting a program list set in one of the program communities (program community SSS) to which user A belongs and a program list set in the other program community (program community Golf) to which user B belongs into the respective television sets. The program list is, for example, an automatic recording list, a viewing list, or the like. 
     That is, a list of programs is created according to conditions set by users A and B for the program community SSS as a program list (SSS to 0012 shared by User A, User B). For example, when user A sets a recording restricted to a time range A and user B sets a recording restricted to a time range B in the program community SSS, a list of programs corresponding to both of the time ranges A and B is created as a program list (SSS to 0012 shared by User A, User B). Similarly, a program list is generated that satisfies an OR condition of users B and C as a program list (Golf to 0024 shared by User B, User C). 
     By downloading the above-described program lists to the television set &lt;TV Set&gt;0012 and the television set &lt;TV Set&gt;0024 and combining automatic recording schedules such that the television set 0012, in which the accounts of users A and B are registered, records a program scheduled for automatic recording on the basis of a program list (automatic recording schedules) provided by one of the program communities, and the television set 0024 viewed by users C and B records programs scheduled for automatic recording on the basis of automatic recording schedules provided by the other program community, user B is capable of viewing programs proposed by each of the program communities. Further, user A is capable of viewing a program to be recorded on the basis of a program list from a program community to which user A belongs. Similarly, user C is capable of recording and viewing a program recorded on the basis of a program list from a program community (program community in which user C registers a user account) to which user C belongs. 
       FIG. 39  illustrates an example of filtering (condition settings) based on automatic recording condition settings &lt;“‘+++ community’ community auto recording setting”&gt;. 
     For example, when the number of programs scheduled for automatic recording on the 12th is one and the length of the program is two hours, the entire program can be recorded with a setting of three hours per day. 
     For example, when the number of programs scheduled for automatic recording on the 13th is three, the length of the programs is two hours, one hour, and two hours, two of the programs in ascending order of the scheduled time can be recorded (the third program cannot be recorded) with a setting of three hours per day. 
       FIG. 40  relates to the order of priority for channels as candidates for recording in the automatic recording condition setting. More specifically, programs of a channel given with a higher priority in the EPG searcher shown in  FIG. 35  is filtered as candidates for scheduled automatic recording. 
     That is, in the example of  FIG. 40 , programs of a channel “CH-DDX” are stored in a scheduled automatic recording list as candidates for scheduled automatic recording. 
       FIG. 41  illustrates an example of filtering in which an event (scheduled in advance by a user) is taken into consideration. 
     When a shared list shared by members of a program community exists and a program which has been scheduled in advance by a user is included in the list, the program is excluded from the candidates for scheduled automatic recording by the third filtering device &lt;User Timer Rec Filter&gt;. 
       FIG. 42  illustrates an example of timing for update &lt;Upload&gt; of scheduled automatic recording. 
     A television set acquires an automatic recording list &lt;Auto Rec List&gt; for scheduled automatic recording at least once a day from the server. Accordingly, prior to the update (acquisition), schedule information &lt;Reserve Data&gt; stored in the television set is uploaded to the server. In this case, when the television set is powered off (not powered on) or in a sleep mode, the television set is powered on prior to the upload. 
     When schedule information &lt;Reserve Data&gt; is uploaded from a television set, an automatic recording schedule list for the television set is prepared in the server. When the television set has not been powered on, the television set is powered off (set to a sleep mode) once downloading of the automatic recording schedule list from the server (acquisition of the list) has been completed. 
       FIGS. 43 and 44  illustrate an example of setting the order of priority in scheduled automatic recording set in the television set  101 . In the setting, an order of priority is set for each of a plurality of program communities in which a plurality of users registered in the television set  101  are registered. Personal accounts (Father) and (Saya) and a common account (no name) are registered in the television set  101 , and are managed by the server  1001  in which a unique identifier is assigned to each account. Each of the accounts can be registered in an arbitrary program community, and can acquire an automatic recording list from each program community. The personal accounts “Father” and “Saya” may be registered in different devices. As for the setting method, a program community for which the order of priority should be changed is selected by operating the [↑] and [↓] keys on the cursor pad of a remote control so that (a display of) the program community is moved to a position to which the program community should be moved, thereby determining the order of priority, as shown in  FIG. 28 . A program community positioned on an upper side is given with a higher order of priority (more reliable recording can be expected). 
     By operating (turning on/pressing) an [Enter] key of the remote control unit once [first time], the target program community is selected. By operating (turning on/pressing) the [Enter] key of the remote control unit once more [second time], the selected program community is deselected. 
     As described with reference to  FIG. 38 , when two or more recording devices (television sets) are provided, a unified recording device (recording destination device) may be used for each program community. Further, as described with reference to  FIG. 41 , a program for which the user has already set scheduling is recorded with a higher priority. 
       FIG. 45  illustrates a preview of an automatic recording schedule using a program community service. 
     In the television set  101 , the user is capable of checking information on a program community to which a program to be recorded according to scheduled automatic recording using a program community service belongs, information on a relevant program community, a program list obtained by registering in the program community, and the like on a program community top screen. When the user is registered in a program community, the program community top screen displays a program proposed by the program community as a picture-in-picture (PinP) in a PinP display region, as exemplified in  FIG. 5D . 
       FIG. 48  illustrates a configuration of a program list processing application &lt;Community Program List API&gt; of the server (cloud service). 
     The program list processing application allows a plurality of user interfaces, such as agents &lt;Agents&gt; that function as signal processors configured to display a variety of screen displays or the like that shift according to selection by the user on a program community top screen shown in  FIG. 5E ,  FIG. 5F , or  FIG. 45 , for example, to be shared. It is to be noted that “N” represents a positive integer. 
     The program list processing application is obtained by allowing individual agents &lt;Agents&gt;, i.e., the EPG searcher &lt;EPG Daily Searcher&gt;, a ranking injector &lt;Timer Recording Ranking Injector&gt;, a hot list injector &lt;“+++” Hot List Injector&gt;, and a user schedule setting part &lt;Personalized Recommendation Injector&gt;, which will be described with reference to  FIG. 34  and the like, to be shared. 
     The EPG searcher is an application (program) which acquires data from a Nimbus EPG searcher &lt;Nimbus EPG Searcher&gt;, and the ranking injector similarly acquires data from a Cloud Log/HDEX Log Searcher &lt;Cloud Log/HDEX Log Searcher&gt;. The host list injector &lt;“+++” Hot List Injector&gt; acquires data from a Nimbus hot list application &lt;Nimbus “+++” Hot List API&gt;, and the user schedule setting part similarly acquires data from a recommendation engine &lt;Recommendation Engine&gt;. 
     A search result &lt;Search Result of Programs&gt; by the program list processing application is stored (recorded) in the recording device. 
     Next, an embodiment that achieves the above-described request will be described.  FIGS. 11A to 29  illustrate screen display examples and processing examples in the television set  101 .

       FIG. 29  illustrates an operation when [Automatic recording &lt;“Auto Recording”&gt;] is not set (unset). 
     Scheduled recording or scheduled viewing by registration in a program community needs to be performed after setting automatic recording in the main body of the television set  101 . Accordingly, when subscription settings are made from the program community list, it is necessary to check whether automatic recording settings have been made, display an alert message when the settings have not been made, and guide the user to make automatic recording settings. 
     As shown in  FIG. 29 , in the automatic recording settings, in association with registration in the program community, a program community is selected [29-1], the [Register] button is turned on (pressed) [29-2], a registration confirmation pop-up message is displayed [29-3], whether automatic recording settings have been made or not is determined [29-4], and it is confirmed that the automatic recording settings have been made [29-4-YES]. 
     When the automatic recording settings have not been made [29-4-NO], a pop-up message confirming the intention to set automatic recording is displayed [29-5], and an “automatic recording basic settings” screen is displayed and the user is prompted to make automatic recording settings [29-6]. 
     After that, the “Register/automatic recording” screen shown in  FIG. 5D  is displayed scheduled recording or scheduled viewing is enabled by registration in the program community, and thereby [Automatic recording] settings are completed. 
     By thus selecting (registering in) a program community (cluster group) on the basis of a cluster group (program community) in which a performer, a group, an arbitrary member of the group members, a genre, a co-star, and the like of a program stored in the television set (recorded program list)  101  are set as clusters, it is possible to present optimum and various program search results matching the user&#39;s viewing request (demand) (scheduled automatic recording), without the need to enter characters during viewing of a program being broadcast or a recorded program being played back. 
     Further, since the search result is displayed not as a list of programs but as a list of an arbitrary number of cluster groups, a high extensibility can be provided in a search procedure by a user (member). 
     Since the program community (cluster group) can be edited (modified) or added by registered members (users), each user&#39;s (member&#39;s) know-how on search is accumulated, and precision in search result is improved. Further, since the search result in which know-how on search is accumulated can be shared among the users (members) of the program community (cluster group), a proposal (refinement) made by a small number of well-informed people can be enjoyed by a number of users. 
     Moreover, since users with similar interests and preferences gather in a cluster group, communications are encouraged among the users with similar interests and preferences.
