     1. Outline of embodiment of the present invention 
     2. Structure of time/date information providing system 100 according to one embodiment 
     3: Variant (Filtering restriction of transmission and/or reception of time/date information) 
     4: Conclusion 
     (1. Outline of Embodiment of the Present Invention) 
     The outline of one embodiment will be described prior to explaining the time/date information providing system  100  according to one embodiment of the present invention in detail. 
     As previously described, a user utilizes schedule management software installed in a personal computer or the like to manage his/her schedule. For example, information on release dates of new products, dates or periods of events such as cinemas, concerts and sports games is registered so that the user can manage the items of information in association with a calendar. However, typically various items of information on release dates of products, dates or periods of various events (referred to as “time/date information” below) are irregularly provided to unspecified users by providers or sponsors via various methods or information mediums. 
     Thus, the user needs to utilize, for example, newspapers, magazines, television, radio, Internet WEB (World Wide Web) sites for individually acquiring various items of time/date information. For example, the user needs to acquire time/date information on sports game on a WEB site, to acquire information on a release date of new CD from a music magazine, or to acquire information on a broadcast time/date of TV program from a TV program guide. Further, in order to register various items of time/date information in a calendar service for schedule management, the user needed a complicated work of acquiring and registering the time/date information via various information mediums. Thus, there was an issue that when the user does not have any information medium or when the user is too late to acquire, the user may not acquire the time/date information and perform appropriate schedule management. Further, there was an issue that the time/date information providers such as information providers or sponsors may not accurately provide the provision-intended time/date information to the users who may desire the time/date information, thereby losing a business chance. 
     The time/date information providing system  100  according to the embodiment of the present invention can solve the issues and can efficiently provide various items of time/date information on release dates or event information via a communication network. 
     Specifically, the time/date information providing system  100  includes a calendar service providing server and a time/date information distribution service providing server on a network such as Internet for providing time/date information to multiple users&#39; information processing terminals connectable to the network. The calendar service providing server provides a calendar service, that is, a service for user&#39;s schedule management to each user. Thus, the user utilizes an information processing terminal connectable to the network, such as personal computer or cell phone, to access the calendar service providing server, thereby managing his/her schedule. 
     The time/date information distribution service providing server can manage various items of time/date information registered by sponsors and the like and appropriately provide the time/date information to the calendar service providing server. Thus, the user can view various items of time/date information when accessing the calendar service providing server from the information processing terminal to view his/her calendar information. Therefore, the user registers time/date information suitable for his/her preference in association with the calendar, thereby performing the schedule management on the time/date information of his/her interested products or events. Consequently, the user does not need a complicated work of utilizing different information mediums such as WEB sites, television, newspapers and magazines for retrieving desired time/date information, or saving and managing the time/date information in his/her information processing terminal. Furthermore, the information providers such as sponsors register the provision-intended time/date information in the time/date information distribution service providing server, thereby accurately providing the time/date information to the users who have accessed the calendar service providing server. 
     In this manner, the time/date information providing system  100  according to the embodiment of the present invention can efficiently provide various items of time/date information on release dates or event information via a communication network. In the following, the time/date information providing system  100  according to the embodiment of the present invention having the above characteristics will be described in detail. 
     (1. Structure of Time/Date Information Providing System  100  According to One Embodiment) 
     At first, the entire structure of the time/date information providing system  100  according to one embodiment of the present invention will be described.  FIG. 1  is a block diagram showing the entire structure of the time/date information providing system  100  according to the present embodiment.

     When the user operates an operation unit (not shown) to instruct the information processing terminal  102  about various processings, the operation input unit  108  transmits instruction information corresponding to the instruction to each function unit of the information processing terminal  102 . For example, the communication control unit  104  and the display control unit  106  described above can transmit and/or receive various items of data based on the user&#39;s instruction information transmitted from the operation input unit  108 , or display various items of information. 
     The user-operable operation unit may include mouse, keyboard, touch panel, button, switch, lever and the like, for example, but is not limited to specific operation units as long as it is user-operable. 
     There has been described above the functional structure of the information processing terminal  102  configuring the time/date information providing system  100  according to the present embodiment, but the functional structure shown in  FIG. 1  is one example for explaining the present embodiment and is not limited thereto. Further, the information processing terminal  102  may include personal computer, television receiver, cell phone, PDA, portable music player and the like, for example, but is not limited to specific devices as long as it has each function described above. Furthermore, the time/date information providing system  100  according to the present embodiment may include a plurality of information processing terminals  102 , and the information processing terminals  102  may be different as long as they include each function described above. Therefore, the user utilizes a personal computer installed at his/her home to access various providing servers or utilizes a cell phone outside his/her home to access various providing servers, thereby utilizing the time/date information providing system  100 . 
     (Calendar Service Providing Server  112 ) 
     Next, the calendar service providing server  112  is directed for providing a calendar service to the users on a network. The calendar service is a service of providing information on year, month and date and user&#39;s schedule information to be associated for schedule management to each user. The user can access the calendar service providing server  112  from the information processing terminal  102  to view his/her schedule information associated with the information on year, month and date. Thus, the calendar service providing server  112  includes a storage area such as a calendar information storage unit  114  for storing therein a database of the schedule information managed for each user. 
     Further, the calendar service providing server  112  can receive time/date data  116  recording therein various items of time/date information from the time/date information distribution service providing server  118  described later to store the same in the calendar information storage unit  114 . Thus, the user can view various items of time/date information provided by various sponsors when accessing the calendar service providing server  112  from the information processing terminal  102  to view his/her schedule information. At this time, when finding time/date information on preferred events or products, the user can register the time/date information in association with his/her schedule information. In response thereto, the calendar service providing server  112  can record the user-registered time/date information in the database in association with the user&#39;s schedule information. Therefore, each time the user accesses the calendar service providing server  112 , the user can confirm the registered time/date information, that is, a release date of preferred product or a date of event as his/her schedule information. 
     The calendar service providing server  112  can automatically acquire the time/date data  116  from the time/date information distribution service providing server  118  or acquire predetermined time/date data in response to a user&#39;s instruction every constant period. The method or period for acquiring the time/date data  116  by the calendar service providing server  112  may be arbitrarily set and changed by a system manager or user, and is not limited to specific acquiring methods or acquiring periods. 
     (Time/Date Information Distribution Service Providing Server  118 ) 
     Next, the time/date information distribution service providing server  118  is directed for providing time/date information to the users on a network and functions as the time/date information providing server according to the present invention. As described above, the time/date information is provided by the information providers such as sponsors, like release dates of products and dates or periods of events, for example. The time/date information may include release dates of CDs or books, broadcast time/date of television programs, release dates of new products, playdays of cinema or concerts, dates of sports games such as baseball or soccer, event schedule of the Olympic games, and the like. Further, the time/date information may be information associated with time and date such as birthdays of famous persons, bargain days of supermarkets, “what day it is today”, and weather forecast associated with time and date, and is not limited to the specific information. 
     Previously, the time/date information was individually provided to unspecified users via unspecified information mediums by the information providers such as sponsors having the items of time/date information. On the contrary, when the time/date information providing system  100  according to the present embodiment is utilized, if having provision-intended time/date information, the information provider registers the time/date information in the time/date information distribution service providing server  118 . In response thereto, the time/date information distribution service providing server  118  saves the time/date data  116  recording therein the time/date information registered by the information providers in the storage area such as time/date data storage unit  120 . 
     The user can access the time/date information distribution service providing server  118  via the communication network  110  from the information processing terminal  102  to view and acquire his/her desired time/date information. Further, the user can register the thus acquired time/date information in the schedule information provided by the calendar service providing server  112  via the communication network  110 . In response thereto, the calendar service providing server  112  can record the user-registered time/date information in the database in association with the user&#39;s schedule information. As a result, the user can view the time/date information on registered products or events when viewing his/her schedule through the calendar service. 
     Furthermore, the calendar service providing server  112  can acquire the time/date data from the time/date information distribution service providing server  118  every constant period and save the same in the calendar information storage unit  114  or the like, for example. Thus, the user can view various items of time/date information provided by various sponsors when accessing the calendar service providing server  112  via the communication network  110  from the information processing terminal  102  to view his/her schedule information. At this time, if finding preferred events or products, the user can register the time/date information on the events or products in association with his/her schedule information. In response thereto, the calendar service providing server  112  can record the user-registered time/date information in the database in association with the user&#39;s schedule information. Consequently, the user can view the time/date information on registered products or events when viewing his/her schedule through the calendar service. 
     In this manner, the information providers such as sponsors can provide the time/date information to all the users utilizing the calendar service provided by the calendar service providing server  112  only by registering the provision-intended time/date information in the time/date information distribution service providing server  118 . As a result, when utilizing the calendar service to view user&#39;s own schedule, the user can view and manage the time/date information together. 
     In the present embodiment, the time/date data  116  recording the time/date information therein is stylized in a predefined format and is transmitted and/or received on the time/date information providing system  100  in a unified manner, for example. The format information recoded in the time/date data  116  includes time/date (period), subject, location and the like, for example, but is not limited thereto. In other words, the recording format of the time/date data  116  is set and changed by a system manager or the like, and is not limited to specific information. Further, the format information recorded in the time/date data  116  may include meta information provided by the meta information addition service providing server  124  described later. The meta information may include explanation, associated HP&#39;s URL, icon&#39;s URL, image&#39;s URL, retrieval tag, transmitter information, processor information, extension information and the like, for example, but is not limited thereto. 
       FIG. 2  is an explanatory diagram showing a concept in which meta information is added to the time/date data  116 . With reference to  FIG. 2 , it can be seen that the original time/date data  116  records therein time/date information on a CD release date of “Artist A”. On the contrary, it can be seen that the time/date data added with the meta information is added with various items of information such as track list of the CD or URL of its jacket photograph. 
     As described above, the recording format of the time/date data  116  utilized on the time/date information providing system  100  is unified so that the time/date information can be more efficiently provided to the user. For example, the calendar service providing server  112  can manage the time/date data  116  acquired from the time/date information distribution service providing server  118  without performing any processing such as format conversion. Furthermore, various items of time/date information recorded in the time/date data  116  can be previously notified to the users&#39; information processing terminals  102  prior to the first date of event indicated by the time/date information. Further, also when directly acquiring the time/date data  116  from the time/date information distribution service providing server  118 , the user can edit and add the information in conformity to the recording format and register the same in the calendar service providing server  112 . 
     (Meta Information Addition Service Providing Server  124 ) 
     Then, the meta information addition service providing server  124  is directed for providing meta information associated with time/date information to the users over a network, and functions as the meta information providing server in the present invention. As stated above, the time/date data  116  records therein time/date information on products or events such as time/date (period), subject and location. The meta information addition service providing server  124  manages detailed information on the products or events, for example, the information on explanation, associated HP&#39;s URL, icon&#39;s URL, image&#39;s URL and the like as the meta information. 
     Previously, the meta information was individually provided to unspecified users via unspecified information mediums by the meta information providers such as sponsors having the meta information. On the contrary, when utilizing the time/date information providing system  100  according to the present embodiment, if having the provision-intended meta information in addition to the time/date information on products or events, the meta information provider registers the meta information in the meta information addition service providing server  124 . In response thereto, the meta information addition service providing server  124  saves meta data  128  recording therein the meta information registered by the meta information providers in the storage area such as a meta data storage unit  126 . 
     The user can access the meta information addition service providing server  124  via the communication network  110  from the information processing terminal  102  to view and acquire the meta information associated with his/her desired time/date information. Further, the user can register the thus acquired meta information in the schedule information provided by the calendar service providing server  112  via the communication network  110 . In response thereto, the calendar service providing server  112  can record the user-registered meta information in the database in association with the user&#39;s schedule information. Consequently, the user can view the meta information associated with the registered products or events when viewing his/her schedule through the calendar service. 
     Further, the time/date information distribution service providing server  118  can, for example, acquire the meta data  128  from the meta information addition service providing server  124  every constant period and add the meta information to the time/date information recorded in the time/date data  116  for saving. Thus, the user accesses the time/date information distribution service providing server  118  via the communication network  110  from the information processing terminal  102  to acquire the time/date data  116 , thereby acquiring and viewing the meta information not only the time/date information on predetermined products or events. Therefore, if finding preferred events or products, the user can register the time/date information and the meta information on the events or products in association with his/her schedule information. In response thereto, the calendar service providing server  112  can record the time/date information and the meta information registered by the user in the database in association with the user&#39;s schedule information. Consequently, the user can view the time/date information and the meta information on the registered products or events when viewing his/her schedule through the calendar service. 
     As described above, the calendar service providing server  112  can acquire the time/date data  116  from the time/date information distribution service providing server  118  every constant period and save the same in the calendar information storage unit  114  or the like. The thus acquired time/date data  116  may be added with the meta information by the time/date information distribution service providing server  118  as described above. In such a case, the user can view various items of time/date information or meta information provided by various sponsors when accessing the calendar service providing server  112  via the communication network  110  from the information processing terminal  102  to view his/her schedule information. At this time, if finding preferred events or products, the user can register the time/date information or the meta information thereof in association with his/her schedule information. In response thereto, the calendar service providing server  112  can record the time/date information or the meta information registered by the user in the database in association with the user&#39;s schedule information. As a result, the user can view the time/date information and the meta information on the registered products or events when viewing his/her schedule through the calendar service. 
     In this manner, the meta information providers such as sponsors can provide the meta information to all the users utilizing the calendar service provided by the calendar service providing server  112  only by registering the provision-intended meta information in the meta information addition service providing server  124 . As a result, the user can view and manage the meta information in addition to the time/date information when utilizing the calendar serve to view his/her own schedule or the like. 
     There has been described above the entire structure of the time/date information providing system  100  according to the present embodiment with reference to  FIG. 1 . The entire structure shown in  FIG. 1  is merely one example for explaining how to provide the time/date information as a characteristic of the present embodiment, and the present invention is not limited to the structure shown in  FIG. 1 . For example, of course, the information processing terminal  102  can additionally include various functions such as broadcast receiving function, speech inputting/outputting function and photographing function depending on an apparatus to be utilized. Each providing server has been indicated as an independent providing server in  FIG. 1  for convenient explanation, but one or two providing servers may include the functions provided by the providing servers, of course. 
     (3. Variant) 
     In the time/date information providing system  100  configured in the above manner, the filtering processing based on user&#39;s preference information enables arbitrary time/date data  116  or meta data  128  to be transmitted and/or received. In the following, a variant of the time/date information providing system  100  will be described. 
     The user can register his/her preference information and the like in the information processing terminal  102 , for example. Thus, the information processing terminal  102  can receive only the information suitable for user&#39;s preference information from each providing server. The user-registered preference information may include categories of sports or music, hours of TV programs, entertainers, regions and the like, but is not limited thereto. 
       FIG. 3  is an explanatory diagram showing a concept in which the information processing terminal  102  receives only the information suitable for user&#39;s preference information from each providing server based on the registered preference information. As shown in  FIG. 3 , the information processing terminal  102  can filter and receive only the information suitable for the registered preference information among various items of information transmitted from each providing server and block other items of information. As a result, the user does not need to receive unnecessary information unsuitable for his/her preference. 
     The reception of various items of information based on the preference information can be adapted to other than the information processing terminal  102 . For example, the manager of the calendar service providing server  112  or the like can register only the information which is intended to be provided through the calendar service as the preference information in the calendar service providing server  112 . In this case, the calendar service providing server  112  can block from receiving unauthorized time/date data  116  or meta data  128  from the time/date information distribution service providing server  118  or the meta information addition service providing server  124 . 
     The user&#39;s preference information may be registered in not only the information processing terminal  102  but also each providing server. In this case, each providing server can transmit various items of information suitable for the user only to arbitrary users&#39; information processing terminals  102  based on the registered preference information.  FIG. 4  is an explanatory diagram showing a concept in which each providing server transmits predetermined information to only specific information processing terminals  102  based on the registered preference information. 
     As shown in  FIG. 4 , each providing server can filter the information processing terminals  102  for which predetermined information to be transmitted and preference information are matched among a plurality of information processing terminals, and transmit the information to only the filtered information processing terminals  102 . As a result, each providing server can provide the information to only the users desiring the information to be provided. 
     Each providing server can receive a request signal of requesting to transmit various items of information from only specific information processing terminals  102 . For example, each providing server can transmit the information to the information processing terminals  102  only when having received the request signal from the information processing terminals  102  of the service-registered users. 
       FIG. 5  is an explanatory diagram showing a concept in which each providing server receives a request signal of requesting to transmit various items of information from only specific information processing terminals  102 . As shown in  FIG. 5 , each providing server can receive only the request signal from the information processing terminals  102  registered in the provided service, and transmit the requested information to only the information processing terminals  102 . Each providing server can block the request signal from the information processing terminals  102  which has not been registered in the provided service, for example. Thus, an operator of each providing server or the like can provide the information only to the service-registered users or information processing terminals  102 , thereby efficiently developing the business utilizing the time/date information providing system  100 . 
     Each providing server can efficiently transmit a plurality of items of managed information to the information processing terminals  102  or other providing servers by utilizing the preference information, a predetermined similarity retrieving algorithm or the like. 
       FIG. 6  is an explanatory diagram showing a concept in which each providing server filters only predetermined information together among multiple items of managed information and transmits the same to the information processing terminals  102  or other providing servers. As shown in  FIG. 6 , each providing server can filter only predetermined information together among multiple items of managed information and transmit the same to the information processing terminals  102  or other providing servers. For example, the time/date information distribution service providing server  118  can extract similar time/date data  116  by the predetermined similarity retrieving algorithm and transmit the extracted items of time/date information  116  together to the information processing terminals  102 . Thus, the items of time/date information which have been previously provided by different information providers individually are provided together to the users, which leads to user&#39;s improved convenience. 
       FIG. 7  is an explanatory diagram showing a concept in which only specific information among multiple categories of information provided by a certain information provider is extracted by each providing server and transmitted to the information processing terminals  102 . As shown in  FIG. 7 , when a certain information provider provides multiple different categories of information to the users, each providing server can extract only specific information from the information and transmit the same to the information processing terminals  102 . Each providing server can transmit only specific information suitable for preference information to predetermined information processing terminals  102  based on the user-registered preference information, for example. As a result, the information provider can extract and efficiently provide only the information suitable for each user (information processing terminal  102 ) also when providing multiple different categories of information. 
     In this manner, in the time/date information providing system  100  according to the present embodiment, the transmission destinations or reception destinations of various items of information are arbitrarily restricted or filtered, thereby efficiently transmitting and/or receiving the information. The examples shown in  FIGS. 3 to 7  are merely exemplary for explaining the concept of the transmit and/or receive of various items of information, and the transmitting and/or receiving method is not limited to the examples. 
     (4. Conclusion) 
     There has been described above the time/date information providing system  100  according to one embodiment of the present invention in detail. As stated above, the calendar service providing server  112  can not only provide the calendar service of managing user&#39;s own schedule but also provide various items of time/date information desired by information providers such as sponsors to the users in association with the calendar information. Thus, the user can view the time/date information on various products or events when utilizing the calendar service to view his/her schedule. Further, the user can perform schedule management on the release date of product or the time/date of event together with his/her schedule by registering the time/date information on preferred product or event in the calendar service. 
     The calendar service providing server  112  can provide various items of meta information desired by the information providers such as sponsors together with the time/date information in association with the calendar information to the users when providing the calendar service. Thus, the user can not only perform schedule management on the time/date information on preferred products or events but also view detailed information on the products or events. 
     As a result, the user does not need to acquire the time/date information or meta information by utilizing different recording mediums or methods. Further, the user does not need to save the time/date information or the meta information in the information processing terminal  102 , thereby viewing the time/date information or the meta information via the communication network  110  from multiple information processing terminals  102 . Furthermore, the user can view and acquire various items of information when utilizing the calendar service to view his/her schedule, thereby efficiently preventing from forgetting to acquire the time/date information. 
     Further, the information provider can also utilize the time/date information providing system  100  to efficiently provide time/date information or meta information to all the users utilizing the calendar service only by registering the provision-intended time/date information or meta information in each providing server. Consequently, the information provider does not need to distribute the time/date information via multiple information mediums such as television, newspapers and radio, thereby efficiently providing the provision-intended time/date information to the users. 
     Furthermore, the use of the time/date information providing system  100  enables each providing server&#39;s manager to further develop the business. For example, since the information provider can manage the relationship between the provider (sponsor) and the user of the time/date information, it can also propose an accounting system via a user&#39;s access to the time/date information. For example, the information provider can propose an accounting system such as accounting for each data, accounting for each event, accounting for each set of similar events, or monthly or yearly subscription. Further, the manager providing the calendar service can propose an accounting system depending on the amount of registration of various items of information from the information providers providing time/date information or meta information. 
     As stated above, the time/date information providing system  100  according to one embodiment of the present invention can efficiently provide various items of time/date information on release dates or event information via a communication network. 
     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.
