CROSS REFERENCES TO RELATED APPLICATIONS
The present invention contains subject matter related to Japanese Patent Application JP 2007-291178 filed in the Japan Patent Office on Nov. 8, 2007, the entire contents of which being incorporated herein by reference.
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a remote control terminal, an information acquiring apparatus, an information providing apparatus, an information providing system, an information providing method, and a program.
In recent years, in conjunction with provision of video and audio information of a program, a system which provides program meta information including a program guide, program information, related information of a program, and the like is popularized. As the program meta information, EPG-SI (Electronic Program Guide—Service Information) information, Electronic Content Guide (ECG) information, and the like are known. A user of a system of this type watches program meta information, in addition to video information of a program which is acquired by a receiving terminal such as a television receiver and displayed on a display screen of the receiving terminal.
SUMMARY OF THE INVENTION
In general, program meta information is displayed to be superposed on video information displayed on the display screen of a receiving terminal or to be parallel to video information reduced-displayed on a part of the display screen. For this reason, for example, when a plurality of viewers watch a program, a viewer who wants to watch video information may feel bothered by a display of the program meta information displayed together with the video information. On the other hand, when the display of the program meta information is temporarily stopped by a changing operation or the like of the screen display, a viewer who wants to browse the program meta information cannot temporarily browse the program meta information and may feel inconvenienced. Even though a single viewer watches a program, the viewer may feel troubled by operations of temporarily stopping the display of the program meta information and restarting the display.
In general, program meta information is displayed as information inherent in a program on the display screen of a receiving terminal. For this reason, since the information inherent in the program is displayed regardless of the preference of the viewer, a specific viewer may feel bothered by a display of program meta information which is not suitable for her/his own preference.
In general, program meta information is acquired by a receiving terminal in conjunction with watching of a program and displayed. For this reason, it is difficult that a viewer can browse program meta information of another program while watching video information of a specific program, or, even though the viewer browses the program meta information, the viewer may be requested to perform a cumbersome operation.
In general, program meta information is acquired by a receiving terminal such as a television receiver or the like and displayed. For this reason, a range of usage of the program meta information is limited, and it is difficult to achieve promotion of utilization.
It is desirable to provide a remote control terminal, an information acquiring apparatus, an information providing apparatus, an information providing system, an information providing method, and a program which make it possible to efficiently browse program meta information and effectively provide the program meta information.
According to a first embodiment of the present invention, there is provided a remote control terminal which can communicate with an information providing apparatus which provides electronic content guide information related to a program and an information acquiring apparatus which acquires and displays video information of the program and the electronic content guide information, and which can remote-control the information acquiring apparatus. This remote control terminal includes: a program identification information acquiring unit which acquires program identification information to designate a program watched by using the information acquiring apparatus; a channel selection control unit which remote-controls a channel selecting process by the information acquiring apparatus based on the acquired program identification information; a scenario information acquiring unit which acquires scenario information included in the electronic content guide information related a program to be watched based on the acquired program identification information; a display unit which displays the scenario information related to the program to be watched; and a display control unit which can control the display unit such that a display state of the scenario information related to the program to be watched is changed depending on a display state of the scenario information in the information acquiring apparatus based on predetermined setting information or predetermined operation information.
According to the configuration, in the remote control terminal, when the remote control of the channel selecting process is performed, based on the program identification information to designate the program watched by using the information acquiring apparatus, scenario information related to the program to be watched is acquired from the information providing apparatus. Based on the setting information or the operation information, depending on the display state of the scenario information in the information acquiring apparatus, the display unit is controlled such that the display state of the scenario information related to the program to be watched is changed.

In the meta data, the ID “es00001”, the name “ECG set 1”, the providing start date and time “2007/7/1 00:00:00”, and the providing end date and time (or an available period) “2007/7/20 00:00:00” are described. Although the details will be described later, attribute information (terminal information) “receiving terminal” and updating information (version information) “1.0” of the ECG set are described. Four ECG data with item IDs (content id) “c11”, “c12”, “c13”, and “c14” constituting the ECG set 1 are described. For example, with respect to the ECG data of the item ID “c11”, a data type “program (program information)”, a program information ID “P011”, providing start date and time “2007/7/1 00:00:00”, providing end date and time “2007/7/10 22:00:00”, and the like are described.

The providing start dates and times and the providing end dates and times of the ECG data with the item IDs “c11”, “c12”, and “c13” corresponding to the program information are set as a period before the program providing date and time (22:00 to 23:00 on 2007/7/10), a providing period, and a period after the providing date and time, respectively. On the other hand, the providing start date and time and the providing end date and time of the ECG data with the item ID “c14” corresponding to the related information are set periods before and after a period in which the program is provided, respectively, the periods including the period in which the program is provided. For this reason, when the ECG scenario including the ECG set 1, as program information, the ECG data with the item IDs “c11”, “c12”, and “c13” are displayed in the period before the program providing date and time, the providing time, and the period after the providing date and time, respectively.

Attribute information (terminal information) “commander” and updating information (version information) “1.0” of the ECG set are described.
(Process Flow of ECG Scenario)
FIG. 8 is a flow chart showing a process flow in execution of the ECG scenario.
Prior to the execution of the ECG scenario, provision of the ECG service is activated through an operation performed by a user of the commander 100 and the receiving terminal 200 (step S10). When the provision of the ECG service is activated, a latest ECG scenario associated with a selected program is acquired from the ECG server 300 (S12). When the ECG scenario is acquired, for example, according to the meta data shown in FIGS. 6A, 6B, and 6C and FIGS. 7A and 7B, the acquired ECG scenario is executed and processed.
When the ECG scenario is executed, the program information, the related information, and the like constituting the ECG scenario are sequentially displayed in units of ECG sets according to the allocated orders of priority (S14). When the display of all the ECG sets constituting the ECG scenario is completed (S18), the display of the ECG scenario is repeated according to the orders of priority again (S20).
When a user finds interested information in the displayed program information or the related information, the user performs a determining operation (S16). When the determining operation is performed, depending on the program information and the related information displayed when the determining operation is performed, a process to display detailed information related to the program information and the related information and to provide various services related to the related information is performed.
In execution of the ECG scenario, when an operation of the commander 100 which is not related to the execution of the ECG scenario or an interrupt event such as updating, changing, and the like of the program table information occurs (S24), the execution of the ECG scenario is ended or temporarily stopped (S26), and the interrupt event is executed (S28).
(Updating Process of Program Information)
FIGS. 9A, 9B, and 9C are diagrams for explaining a display screen obtained before a channel selecting operation process in the commander 100 is performed. FIG. 9A shows a time chart of programs, and FIGS. 9B and 9C show display screens of the commander 100 corresponding to time 1 “00:00” and time 2 “0x:00” shown in FIG. 9A.
As shown in FIGS. 9B and 9c, in the commander 100, program logos of programs which can be watched at the times (In FIGS. 9B and 9C, a program is expressed as specifiable identification information.) are displayed. As shown in FIG. 9A, in channels (Ch) 1, 3, 4, 6, 8, 10, and 12, programs 1-1, 3-1, 4-1, 6-1, 8-1, 10-1, and 12-1 are provided at time 1. In Ch 3, 6, 8, and 10, new programs 3-2, 6-2, 8-2, and 10-2 are provided at time 2.
For this reason, at time 1, as shown in FIG. 9B, program logos of the programs 1-1, 3-1, 4-1, 6-1, 8-1, 10-1, and 12-1 provided at time 1 are displayed. At time 2, as shown in FIG. 9C, program logos of the programs 3-2, 6-2, 8-2, and 10-2 are updated, the provision of which are started at time 2.
FIG. 10 is a sequence diagram illustrating a method of an updating process of the program logos shown in FIGS. 9A, 9B, and 9C.
As shown in FIG. 10, in the commander 100, after a predetermined setting process, a predetermined setting operation, and the like (step S101) are performed, program table information including scheduling information of programs (for example, program identification information, a type of a program, a providing channel, providing date and time, and the like) is acquired from the ECG server 300 (S102). Based on the program identification information included in the program table information, ECG information (program information) expressing the program logo of the watchable program is acquired from the ECG server 300 to be displayed on the commander 100 (S103 to S105).
In this case, in order to update the program information on real time, in the channel selecting operation process, in a predetermined cycle or when updating of scheduling information is confirmed, the latest program table information is acquired from the ECG server 300 (S106). When the change of the watchable program is detected based on the program table information by passage of time (S107), based on the program identification information, program information expressing the program logo of the changed program is acquired from the ECG server 300, and the display of the corresponding program logo is automatically updated (S108 to S110). When a user selects the program logo to perform a channel selecting operation (S111), screen displays of the commander 100 are switched to display ECG information (ECG scenario) related to a program corresponding to the selected program logo.
In this manner, since the program information expressing the watchable program is updated on real time, the user can select a desired program based on the updated program information and browse the ECG scenario.
In the channel selecting process, when the identification information of the user or the commander 100 is communicated to the ECG server 300, for example, based on the program table information, a change of a watchable program is detected by the ECG server 300, and the program information expressing the program logo of the changed program may be automatically provided from the ECG server 300 to the commander 100. In this case, the latest program table information need not be acquired by the commander 100. In place of provision of the program identification information to specify the changed program to the ECG server 300, the program information of all programs which can be watched, when updating of the scheduling information is confirmed, may be acquired from the ECG server 300 and updated.
(Display Process 1 of ECG Scenario)
FIGS. 11A and 11B are explanatory diagrams illustrating display screens obtained after the channel selecting operation process in the commander 100. FIGS. 11A and 11B show a case where display states of the ECG scenario in the commander 100 are changed depending on display states of the ECG scenario in the receiving terminal 200.
In the example shown in FIG. 11A, only video information X of a program is displayed on the receiving terminal 200, and ECG scenarios Xa and Xb are displayed on the commander 100. In the example shown in FIG. 11B, video information X and the ECG scenario Xa are displayed on the receiving terminal 200, and the ECG scenario Xb different from the ECG scenario Xa is displayed on the commander 100.
In the screen display, for example, setting information to change screen displays depending on types (for example, a sport program, a drama, or the like) of a program to be watched is registered in the commander 100 and the receiving terminal 200 in advance. When a program of a type corresponding to the setting information is detected, the screen display is realized by performing a changing process of the screen display. The setting information on the receiving terminal 200 is registered in the commander 100 together with the setting information on the commander 100, and the setting information may be provided to the receiving terminal 200 as needed. The setting information on the commander 100 may not be registered in each commander 100 in advance, and may be registered for each of the users of the commanders 100 like preference information (will be described later).
In particular, when the display of the ECG scenario is stopped on the receiving terminal 200, the pieces of setting information on the commander 100 side and the receiving terminal 200 side may be registered such that the ECG scenario Xa and the ECG scenario Xb the displays of which are stopped on the receiving terminal 200 are simultaneously or sequentially displayed. When the ECG scenario is displayed on the commander 100 and the receiving terminal 200, the pieces of setting information on the commander 100 side and the receiving terminal 200 side may be registered such that the ECG scenario Xa is displayed on the receiving terminal 200 and the ECG scenario Xb is displayed on the commander 100.
In addition to the pre-registration of the setting information, control information to perform a changing process of screen displays may be provided to the commander 100 and the receiving terminal 200 by a control operation of a user. In particular, when the display of the ECG scenario Xa is stopped on the receiving terminal 200, a signal representing the effect is provided from the commander 100 to the receiving terminal 200, and the commander 100 may be controlled such that the displays of the ECG scenario Xa the displays of which is stopped on the receiving terminal 200 and the ECG scenario Xb are performed. When the ECG scenario is displayed on the commander 100 and the receiving terminal 200, a control signal representing the ECG scenario Xa is provided from the commander 100 to the receiving terminal 200, the commander 100 may be controlled to display the ECG scenario Xb. In this manner, in the commander 100, display states of the ECG scenario can be changed depending on display states of the ECG scenarios on the receiving terminal 200.
In this case, as an example of a combination of the ECG scenarios Xa and Xb, for example, a combination of schematic information and detailed information related to a program, a combination of present information related to a program and past or future information (for example, an intermediate step of a sport competition, a sketch of a drama, an advance notice, or the like), and the like are given.
FIG. 12 is a sequence diagram illustrating a method of a changing process of screen displays shown in FIGS. 11A and 11B. In FIG. 12, processes in steps S128 to S134 and processes in steps S135 to S138 are sequentially shown. However, both the processes in both the sequences may be executed in parallel with each other or may be executed in reverse order.
As shown in FIG. 12, in the commander 100, a registering process which registers user identification information in the receiving terminal 200 and the ECG server 300 is performed in advance (S121 and S122). The user identification information mentioned here is information which can specify a user between the commander 100, the receiving terminal 200, and the ECG server 300. In connection with the user identification information, various pieces of information (for example, addresses, contact information, and the like) of users may be stored in the commander 100. In this manner, when various processes such as purchase and payment procedures are performed through the ECG server 300, the stored various pieces of information of the users can be read and used.
In the commander 100 and the receiving terminal 200, a registering process which registers setting information is also performed in advance (S123 to S125). In the commander 100, as shown in FIGS. 9A, 9B, 9C, and 10, when a channel selecting operation is performed, program identification information to specify a program to be watched and user identification information are provided to the receiving terminal 200 and the ECG server 300 (S126 and S127). In this case, the program identification information may be identification information such as a program code allocated to a program to be watched, information of a providing channel, or information of a providing medium as needed. When the information of the providing channel and, as needed, the information of the providing medium, are provided as the program identification information, an arbitrary program can be specified based on scheduling information of programs included in, for example, the program table information or the like.
With respect to the receiving terminal 200, the acquired user identification information is compared with user registration information registered in the receiving terminal 200 in advance. When the user identification information corresponds to any one of the user registration information, the channel selecting process is performed on the acquired program identification information (S128 to S130). In this manner, specific program identification information is shared by the commander 100 and the receiving terminal 200, and a watching channel is linked. The acquired program identification information is provided to the ECG server 300, and the ECG scenario related to the program corresponding to the program identification information is acquired from the ECG server 300 (S131 and S132).
On the other hand, with respect to the commander 100, the user identification information acquired in the ECG server 300 is compared with user registration information registered in the ECG server 300 in advance. When the user identification information corresponds to any one of the user registration information, an ECG scenario related to a program corresponding to the program identification information is extracted and provided (S135 and S136). In this manner, the ECG scenario related to the common program can be displayed between the commander 100 and the receiving terminal 200.
In this case, the ECG scenario acquired in the receiving terminal 200 is displayed in synchronism with the progress of the program based on scheduling information of the program and the present time. When a watching channel is linked, even in the commander 100, similarly, the acquired ECG scenario is displayed in synchronism with the progress of the program.
In the commander 100 and the receiving terminal 200, when, based on pre-registered setting information, watching of a program of a type corresponding to the setting information is detected, the changing process of a screen display is performed (S133 and S137). In this case, the type of the program is determined based on the scheduling information of the program included in, for example, the program table information or the like and/or the program identification information. In order to cope with a change of screen displays, for example, pieces of attribute information representing schematic information, detailed information, information for a commander, information for a receiving terminal, and the like are given in units of ECG scenarios or ECG sets, pieces of program information, pieces of related information, and the like. For example, FIGS. 7A and 7B show a case where pieces of attribute information (terminal information) representing the information for the receiving terminal and the information for the commander are given to the ECG sets constituting the ECG scenario.
For example, when a setting representing that the ECG scenario is not displayed on the receiving terminal 200 is made, as shown in FIG. 11A, in place of a display of the ECG scenario Xa (information for the receiving terminal) on the receiving terminal 200, the ECG scenario Xa is displayed on the commander 100 together with the ECG scenario Xb (S134 and S138). When a setting representing that the ECG scenario Xa (schematic information) is not displayed on the receiving terminal 200 and that the ECG scenario Xb (detailed information) is displayed on the commander 100, pieces of information corresponding to the setting information of the ECG scenario acquired by the commander 100 and the receiving terminal 200 are displayed (S134 and S138). When watching of the program of the corresponding type is detected, for example, a screen display set as a default state may be performed such that the ECG scenarios Xa and Xb are displayed on the commander 100 and the receiving terminal 200, respectively.
In this case, when a watching channel is linked between the commander 100 and the receiving terminal 200, as in the updating process of the program logo, when a change of programs on a channel being selected based on the program table information is detected with passage of time, the ECG scenario related to the changed program is acquired from the ECG server 300, and the screen display is automatically updated.
The case where the ECG scenario corresponding to the setting information is determined by the commander 100 or the receiving terminal 200 is described above. However, the setting information is provided to the ECG server 300, and the corresponding ECG scenario and the information included in the ECG scenario may be subjected to a filtering process on the ECG server 300 side, reconfigured as needed, and provided to the commander 100 and the receiving terminal 200. In place of the change of display states on the commander 100 depending on display states on the receiving terminal 200, the display states on the receiving terminal 200 may be changed depending on the display states on the commander 100.
FIG. 13 is a sequence diagram illustrating another method of linking a watching channel. In the above-mentioned linking method, for example, by using IrDA or the like, one-way communication is performed from the commander 100 to the receiving terminal 200. However, in the other linking method shown in FIG. 13, it is assumed that, for example, by using Bluetooth (registered trademark), two-way communication can be performed between the commander 100 and the receiving terminal 200.
In another method, for example, by an operation or the like of a link operation button by a user, link operation information is provided from the commander 100 to the receiving terminal 200, and program identification information to specify a watched program is provided from the receiving terminal 200 to the commander 100 (S143 to S145). In this manner, without performing a channel selecting operation, a watching channel can be linked between the commander 100 and the receiving terminal 200. In the commander 100, the acquired program identification information and the user identification information are provided to the ECG server 300. After a user identifying process, the ECG scenario related to a program corresponding to the program identification information is acquired from the ECG server 300 (S150 to S152). When the user identifying process is performed in advance, only the acquired program identification information may be provided to the ECG server 300.
In still another linking method, in place of the operation of the link operation button, for example, by using the function of Bluetooth, when a specific commander comes in a range in which another Bluetooth terminal can be searched for by the receiving terminal 200 or another commander, a specific commander may be automatically recognized, and the program identification information to specify a watched program may be provided from the receiving terminal 200 or the other commander to the specific commander (S146 to S149). In this manner, without performing a channel selecting operation, a watching channel can be linked between the commander 100 and the receiving terminal 200.
As an issue in the past, for example, when a program is watched by a plurality of viewers, a certain viewer may desire to watch only video information, and another viewer may desire to browse an ECG scenario. In this case, when video information and the ECG scenario are displayed on the receiving terminal 200, the video information is prevented from being watched when the ECG scenario is displayed, and the ECG scenario is difficult to be browsed when the ECG scenario is not displayed. Even though a program is watched by a single viewer, depending on, for example, the type or the like of the program, the viewer may feel bothered by performing changing operations of screen displays to temporarily stop the display of the ECG scenario and to restart the display.
In the commander 100 according to the embodiment, as shown in FIG. 11A, the screen display is controlled to display only the video information X on the receiving terminal 200 and to display the ECG scenarios Xa and Xb on the commander 100. For this reason, the issue in the past can be solved. As shown in FIG. 11B, when the screen display is controlled to display the different ECG scenarios Xa and Xb on the commander 100 and the receiving terminal 200, respectively, for example, different pieces of information such as schematic information and detailed information related to the program can be efficiently browsed.
The case where setting information to change display screens depending on types of programs to be watched is registered in the commander 100 and the receiving terminal 200 in advance is described above. In this case, the change of the screen displays is controlled on the acquiring side of the ECG scenario, i.e., user sides of the commander 100 and the receiving terminal 200. However, the change of the screen displays, as will be described below, can also be controlled on a providing side of the ECG scenario, i.e., an information service provider side using the ECG server 300.
When the change of the screen displays is controlled on the providing side of the ECG scenario, for example, setting information (attribute information) representing that the change is controlled by the providing side is given to an ECG scenario (or information included in the ECG scenario) desired to be preferentially provided in advance, so that the screen displays can be changed depending on link states of a watching channel.
When a screen display as shown in FIG. 11A is performed, for example, setting information representing a relatively high priority is given to the ECG scenario Xa (or information included in the Xa) in advance, and setting information representing a relatively low priority is given to the ECG scenario Xb (information included in the Xb) in advance. The ECG scenarios Xa and Xb are provided from the ECG server 300 to the commander 100 and/or the receiving terminal 200.
When a watching channel is linked, i.e., the ECG scenario can be browsed on both the commander 100 and the receiving terminal 200, for example, the ECG scenario Xa is displayed on the commander 100, and the ECG scenario Xb is displayed on the receiving terminal 200. In this case, the display of the ECG scenario is stopped on the receiving terminal 200, screen displays are changed, and, based on the setting information, in place of the stoppage of the display of the ECG scenario Xa on the receiving terminal 200, the ECG scenario Xa is preferentially displayed on the commander 100 together with the ECG scenario Xb. In this manner, a viewer can watch only the video information X on the receiving terminal 200 and efficiently browse the ECG scenarios Xa and Xb on the commander 100. When the watching channel is not linked, i.e., when the ECG scenario can be browsed on only any one of the commander 100 and the receiving terminal 200, the ECG scenario Xa may be preferentially displayed on an apparatus, on which the ECG scenario can be browsed, based on the setting information together with the ECG scenario Xb.
With a display configuration as described in FIG. 11B, the ECG scenario Xa (or information included in the Xa) serving as image information can also be displayed on the receiving terminal 200, and the ECG scenario Xb (or information included in the Xb) serving as textual information can also be displayed on the commander 100. In this case, for example, setting information (for example, image information shown in FIGS. 6A and 6B) representing image information is given to the ECG scenario Xa (or information included in the Xa) in advance. Without giving the setting information, a type of information may be determined on an acquiring side of the ECG scenario by a source format of the information included in the ECG scenario. The ECG scenarios Xa and Xb are provided from the ECG server 300 to the commander 100 and/or the receiving terminal 200.
When the watching channel is linked, based on the setting information or the source format, the ECG scenario Xa is displayed on the receiving terminal 200, and the ECG scenario Xb is displayed on the commander 100. In this manner, a viewer can browse the image information on the receiving terminal 200 and efficiently browse the textual information on the commander 100. When the watching channel is not linked, the ECG scenarios Xa and Xb may be simultaneously or sequentially displayed on the commander 100 and/or the receiving terminal 200.
(Display Process 2 of ECG Scenario)
FIGS. 14A and 14B are explanatory diagrams illustrating a display screen obtained after a channel selecting operation process on the commander 100. FIGS. 14A and 14B show cases in which ECG scenarios matched with the preferences of users of the commanders 100 are displayed.
In the example shown in FIG. 14A, when a watching channel is liked, based on pieces of preference information a, b, and c of users using commanders 100a, 100b, and 100c, different ECG scenarios Xa, Xb, and Xc are displayed on the plurality of commanders 100a, 100b, and 100c, respectively. In the example shown in FIG. 14B, based on the pieces of preference information a, b, and c of the commanders 100a, 100b, and 100c, different ECG scenarios Xa, Xb, and Yc are displayed on the plurality of commanders 100a, 100b, and 100c, respectively. In the receiving terminal 200, although an ECG scenario Xo is displayed on the receiving terminal 200, an ECG scenario except for the ECG scenario Xo may be displayed. In addition, the ECG scenario may not be displayed.
The screen display described above is realized such that, for example, preference information for each user is registered in the ECG server 300 in advance, and the ECG scenario is subjected to a filtering process on the ECG server 300 side and provided. Even though the preference information of each user is not registered in advance, control information to perform the filtering process may be provided to the ECG server 300 by a control operation of the user as needed.
In the example shown in FIG. 14A, when the watching channel is linked, on the commanders 100a, 100b, and 100c, the ECG scenarios Xa, Xb, and Xc which are ECG scenarios related to a program being watched and are matched with the pieces of preference information a, b, and c are displayed.
In the example shown in FIG. 14B, on the commanders 100a and 100b, the ECG scenarios Xa and Xb which are ECG scenarios related to a program being watched and are matched with the pieces of preference information a and b are displayed. On the other hand, on the commander 100c, when the watching channel is not liked, the ECG scenario Yc is an ECG scenario related to a program except for the program being watched and is matched with the preference information c is displayed. A program Y may be a program which is provided in the past or a program which will be provided in the future regardless of a program on a channel different from the channel of the program being watched as will be described later.
As an example of the preference information, for example, pieces of information such as program information, sales information, advertising information classified by categories of the ECG scenarios or pieces of information such as a cast, a genre, music, and an event classified by categories of program information may be used.
FIG. 15 is a sequence diagram illustrating a method of a changing process of screen displays shown in FIGS. 14A and 14B. Even in FIG. 15, as in the case shown in FIG. 12, the processes in steps S165 to S170 and the processes in steps S171 to S174 are sequentially shown. However, both the processes in both the sequences may be executed in parallel with each other or may be executed in reverse order.
As shown in FIG. 15, in the commander 100, a registering process which registers user identification information in the ECG server 300 is performed (S161 and S162). When a channel selecting operation for a program is performed, program identification information and user identification information to specify a program to be watched are provided to the receiving terminal 200 and the ECG server 300 (S163 and S164).
With respect to the receiving terminal 200, as described above, a user identifying process is performed when a predetermined condition is satisfied, a channel selecting process is performed based on the acquired program identification information, and a watching channel is linked between the receiving terminal 200 and the commander 100 (S165 to S167). The acquired program identification information is provided to the ECG server 300, and the ECG scenario related to a program corresponding to the program identification information is acquired from the ECG server 300 (S168 and S169). On the other hand, with respect to the commander 100, in the ECG server 300, as described above, a user identifying process (S171) is performed. When a predetermined condition is satisfied, an ECG scenario related to a program corresponding to the acquired program identification information is extracted.
In this case, with respect to the commander 100, in the ECG server 300, the extracted ECG scenario subjected to a filtering process based on preference information of a user is provided (S172 and S173). The ECG scenario is subjected to the filtering process based on attribute information which is allocated to each of pieces of information included in the ECG scenario and expresses a data type (program, sales, advertisement, or the like) of the ECG set. On the receiving terminal 200, the normal ECG scenario Xo is displayed. On the commander 100, the ECG scenarios Xa, Xb, and Xc matched with the preference information of the user are displayed (S170 and S174). In this case, when the preference information is not set, or when the information matched with the preference information can be hardly obtained by the filtering process, a display set as a default state is performed.
When watching is performed without performing a channel selecting operation, in the commander 100, after the program identification information is acquired by the link operation, automatic recognition, or the like shown in FIG. 13, the acquired program identification information and the user identification information are provided to the ECG server 300. In the ECG server 300, the ECG scenario related to the program corresponding to the program identification information is extracted after the user identifying process. After the ECG scenario is extracted, the ECG scenario subjected to the filtering process based on the preference information of the user is provided to the commander 100.
The changing process may be combined with the changing process of screen displays shown in FIGS. 11A and 11B in which the display states on the commander 100 are changed depending on display states of the ECG scenario on the receiving terminal 200. In this case, in place of the ECG scenario Xb shown in FIG. 11B, the ECG scenarios Xa, Xb, and Xc or the like are displayed on the commanders 100a, 100b, and 100c. 
When a watching channel is linked between the commander 100 and the receiving terminal 200, as in the case shown in FIGS. 11A and 11B, an updating process of the ECG scenario is performed with passage of time. As the filtering process of the ECG scenario, in addition to the method shown in FIG. 15, for example, preference information for each user is stored in the commander 100, and, based on the stored preference information, a filtering process may be performed to the ECG scenario acquired from the ECG server 300.
As an issue in the past, when an ECG scenario inherent in a program is displayed on the receiving terminal 200 regardless of the preference of a viewer, specific viewers may feel bothered by a display of an ECG scenario which is not matched with their own preference.
However, in the commander 100 according to the embodiment, as shown in FIG. 14, since a screen display is controlled such that an ECG scenario matched with the preference of the user can be displayed based on preference information for each user, the issue in the past can be solved. In this manner, based on preference information of a user such as information matched with a preference related to a cast, information matched with a preference pattern for each age group, and information matched with a hobby, information related to a program or merchandise can be provided. As shown in FIG. 14B, for example, when link states of a watching channel are switched by an operation or the like of a link operation button, an ECG scenario related to a program except for the program being watched can be browsed.
Even though the preference information of each user is not registered in the ECG server 300 in advance, preference information of the user can be automatically acquired based on information related to a watched program and/or information related to a browsed ECG scenario. In this case, the acquired preference information is accumulated in at least any one of the commander 100 and the receiving terminal 200.
For example, when a program has been watched for a predetermined period of time set in advance, pieces of main information such as a cast, a genre, music, an event, and the like of a program are extracted from ECG information related to the watched program. In browsing of the ECG scenario, when a user operation to select specific information is detected, for example, pieces of main information such as program information, sales information, and advertising information are extracted from ECG information related to selected specific information. A result obtained by analyzing a frequency of each of the pieces of main information is automatically acquired as the preference information of a user.
By using the preference information of the user, for example, information related to a program matched with the preference of the user is selected from the program table information, and can be provided as information related to a recommended program. In this case, when a watching channel is linked, the information related to the recommended program is displayed on the commander 100, the program table information is displayed on the receiving terminal 200, and the displays on the commander 100 and the receiving terminal 200 may be incorporated with each other. More specifically, identification information representing a program corresponding to the recommended program is added to the program table information, and detailed program information related to the program corresponding to the selected recommended program may be displayed on the receiving terminal 200 in conjunction with a selecting operation of the recommended program by the commander 100.
(Other Process)
In the cases shown in FIGS. 11A and 11B and FIGS. 14A and 14B, in the commander 100, information related to acquired ECG scenario may be stored. For example, when a watching channel is linked, when a specific program has been watched for a predetermined period of time (for example, 3 minutes or the like) set in advance, with respect to the watched program, program identification information, identification information (reference ID or the like of the ECG scenario) of the acquired ECG scenario, the acquired ECG scenario, and the like are stored. In this case, the program identification information may be identification information such as a program code allocated to the watched program, information of a providing channel and providing date and time, or information of a providing medium as needed. Even though the watching channel is not linked, the identification information of the acquired ECG scenario, the acquired ECG scenario, and the like are stored.
The information of the acquired ECG scenario may be stored in not only the commander 100 but also the ECG server 300. In this case, identification information (linking information) which can specify the information stored in the ECG server 300 is stored in the commander 100. Based on the stored linking information, information stored in the ECG server 300 for each commander 100 or each user may be appropriately read.
When a user can communicate with the ECG server 300 by using the commander 100, the user can acquire the corresponding ECG scenario from the ECG server 300 and can browse the ECG scenario based on the stored identification information of the ECG scenario. Based on the stored program identification information, another ECG scenario related to a program specified by the program identification information can be acquired from the ECG server 300 and browsed. On the other hand, even though the user does not communicate with the ECG server 300 by using the commander 100, the user can read and browse the stored ECG scenario. In the commander 100, the preference of the user is analyzed based on the accumulated program identification information, and, based on the program table information, the user is notified of starting provision of a program matched with the preference of the user.
The user can communicate the information stored in the commander 100 between the receiving terminal 200, another commander, or another video display apparatus having an ECG information processing function. For example, the stored ECG scenario may be provided to the receiving terminal 200 or another video display apparatus (for example, another receiving terminal, a PVR, a PC, a car navigation system, a mobile telephone, or the like) and displayed on a display screen of the receiving terminal 200 or the other video display apparatus. In this manner, the ECG information can be browsed on an external device except for the commander 100.
When, another commander stores an ECG scenario newer than the ECG scenario stored in the commander 100 of a user, the newer ECG scenario is acquired from the other commander, and the ECG scenario stored in the commander 100 of the user may be updated by the acquired ECG scenario. For example, FIGS. 7A and 7B show a case where updating information (version information) is given to an ECG set constituting an ECG scenario. When an ECG scenario older than the ECG scenario stored in the commander 100 of the user is stored in another commander, a new ECG scenario may be provided to the other commander.
In the commander 100, not only a program provided at the present and including a program being watched by using the receiving terminal 200, but also ECG scenarios related to a program which is provided in the past or a program which will be provided in the future are acquired and displayed.
For example, on the display screen shown in FIG. 9B, a program logo of a program provided o r a program to be provided at specific date and time designated by a user is displayed. When the program logo selecting operation is performed, the program identification information to specify a program corresponding to the selected program logo and the user identification information are provided to the ECG server 300. In this case, the program identification information may be identification information such as a program code allocated to a corresponding program, information of a providing channel and providing date and time, or information of a providing medium as needed. In the ECG server 300, as described above, the user identifying process is performed. When a predetermined condition is satisfied, an ECG scenario related to a program corresponding to the acquired program identification information is extracted and provided to the commander 100. In the commander 100, the acquired ECG scenario is displayed. Also in this case, screen displays can be changed based on the setting information, the preference information, or the like.
An ECG scenario provided to the commander 100 or an ECG scenario displayed by the commander 100 may be arbitrarily changed depending on scheduling information of programs as shown in FIGS. 7A and 7B. In this case, the ECG scenario related to the program is configured such that the ECG scenario can be provided or displayed as different pieces of information during provision of the program, before the program is provided, and after the program is provided. For example, during the provision of the program, the ECG scenario can be provided or displayed as information displayed in conjunction with the progress of the program. Before the program is provided, the ECG scenario can be provided or displayed as information which previously notices the contents of the program. After the program is provided, the ECG scenario can be provided or displayed as information which previously notices the contents of a program for the next time. In place of the ECG scenario related to the selected program, another program provided on a channel which provides the selected program, for example, an ECG scenario related to a program which can be soon to be watched may be provided or displayed.
In the commander 100, identification information of the displayed ECG scenario and the ECG scenario may be stored. Furthermore, when an ECG scenario of a program which will be provided in the future is displayed, a programming operation process to select watching programming or recording programming of the program may be performed. In this case, scheduling information (for example, program identification information, a type of the program, a providing channel, providing date and time, and the like) and programming operation information are stored in the commander 100, and the stored information is read later and provided to the receiving terminal 200, another video display apparatus, another information recording apparatus, or the like. In this manner, a user can efficiently perform a programming operation process by using the scheduling information of the program.
Although a preferred embodiment of the present invention is described in the foregoing with reference to the drawings, the present invention is not limited thereto. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
