  By accessing the web page providing server using a mobile phone, it is also possible to browse information content related to a broadcast program. However, since the display screen of the mobile phone is much smaller than the display screen of the PC, it is difficult to display all the information provided from the PC web page providing server at a time.

  Furthermore, providing a new web page providing server for a mobile phone requires a great deal of cost and generates a large economic burden. Therefore, if broadcast program guidance for a mobile phone can be performed using an existing web page providing server, the convenience of the mobile phone can be more effectively utilized without causing an economic burden.

An object of the present invention is to realize an information content generation apparatus and system capable of providing effective program information to a mobile phone having a small display screen.
Another object of the present invention is to realize an apparatus and system that can provide information content for a mobile phone by using an existing PC web page providing server.
Furthermore, another object of the present invention is to realize a terminal device that can effectively receive information content of a broadcast program and is useful in viewing the broadcast program.

A program information providing system according to the present invention is a program information providing system for providing program information content to a mobile terminal via a network from a program information generating apparatus that publishes broadcast program information on the network.
The program information generation device includes a first program information acquisition unit that accesses a web page providing server that a broadcasting station has opened for viewers and acquires program information;
A second program information acquisition unit that accesses a database that holds information relating to various broadcast programs and acquires related program information related to the program name using the program name acquired from the web page providing server as a keyword ;
Interpreting means for interpreting the meaning of the related program information based on a predetermined rule for the related program information acquired by the second program information acquiring means;
Based on the result of interpretation by the interpretation means, metadata creation means for creating metadata that at least includes the broadcast start time and briefly represents the gist of the broadcast program;
Means for inserting the created metadata into the program information to generate program information content;
Means for publishing the generated program information content on a network,
Means for receiving program information content from the program information generating device via a network;
Means for extracting metadata from the received program information content;
Means for displaying the extracted metadata on the display screen;
And an alarm generating means for generating an alarm at or immediately before the broadcast start time of the broadcast program corresponding to the metadata displayed on the screen.

In the present invention, a PC web page and a program database storing detailed related information of broadcast programs are accessed, and a web page for a mobile phone is created using these information. This saves you the trouble of creating. As a result, it is possible to provide a web page for a mobile phone without causing an economic cost burden.
Here, various information obtained from program information and related program information is included as metadata. For example, not only a part of data extracted from program information is used as metadata but also all program information is converted into metadata. It can also be. Also, information such as alarm information, update information related to program information update, and the urgency of metadata can be included as metadata.
Furthermore, as a method of publishing on a network, it can be published on a WEB page by, for example, HTTP.

  The preferred embodiment of the information content generation device according to the present invention transmits the newly created metadata of the program information content to the terminal device in the standby state, and displays the metadata on the information display unit of the terminal device. And Since the information content as a whole includes a relatively large amount of information, it is difficult to display all the information included in the information content on the screen of the mobile phone at a time. On the other hand, since the metadata briefly represents the gist of the broadcast program, the metadata can be displayed on the display screen of the mobile terminal. Therefore, the viewer can easily know necessary information including the start time of the broadcast program from the metadata displayed on the screen of the mobile phone.

In the information content generation apparatus and system according to the present invention, the program broadcast guide for the mobile phone is created by accessing the web page and program database of the HTTP server for the PC. Program information for telephone can be provided. Furthermore, since the information content of the present invention is attached to the program information with metadata simply indicating only the necessary information of the broadcast program, the broadcast program designated by simply displaying the metadata on the screen of the mobile phone. The necessary information can be notified to the viewer.
In particular, it is possible to inform the viewer of the program start time for the broadcast program desired by the viewer using the metadata and the alarm means, so that convenience can be further improved.

  FIG. 1 is a diagram showing an example of an information content generation system according to the present invention. The information content generation device 2 of the present invention is connected to a communication network 1 such as the Internet or Ethernet (registered trademark). An HTTP server 3 and a program database 4 are also connected to the network 1. The HTTP server 3 is a web page providing server in which broadcast stations publish program guide information for viewers. The program database (program DB) 4 is a database in which a broadcast station holds information related to broadcast programs. Furthermore, a large number of mobile phones 5a to 5n are connected to the network 1, and information content related to broadcast programs is provided from the information content generation device 2 via the network. The information content generation device 2 uses the program information content of the HTTP server 3 to generate information content for mobile phones. In creating the information content, the information content generation device accesses the HTTP server 3 which is a program guide server for PC via the network and acquires the information content related to the broadcast program. Furthermore, the program DB 4 is also accessed as necessary, and detailed related program information related to the broadcast program is acquired. Furthermore, the information content generation apparatus creates metadata from the acquired related program information, inserts the metadata into the information content, and publishes it on the Internet. As a specific method for publishing on the Internet, for example, publishing can be performed using an HTTP WEB page.

  FIG. 2 is a diagram showing an example of an information content generation apparatus according to the present invention. The information content generation apparatus includes a communication interface 10, a web page extraction unit 11, a program DB extraction 12, a semantic interpretation unit 13, a rule holding unit 14, a metadata conversion unit 15, and a web page reconstruction unit 16. The communication interface 10 is a transmission / reception interface of the Internet or Ethernet (registered trademark), and accesses the HTTP server and the program DB via the interface and publishes the generated information content on the network. Furthermore, using the communication interface, the created metadata is transmitted to the mobile phone in a standby state and displayed on the display.

  The web page extraction unit 11 accesses the HTTP server 3 and extracts a script for displaying program information from the HTML data of the HTTP server 3. As an example of the extraction method, the words “program information start” and “program information end” are written in the comment sentence of HTML data in advance before and after the extracted script. Script can be extracted. An example of the extraction program is shown in FIG.

  The program DB extraction unit 12 accesses the program DB 4 and extracts detailed related information related to the program name held in the program DB using the program name in the script acquired from the web page extraction unit 11 as a keyword. Examples of information held in the program DB include the broadcast start and end times of the program, the genre of the broadcast program, the performers, and the program outline (summary).

  The semantic interpretation unit 13 interprets program information acquired from the program DB based on rules held in a rule holding unit 14 described later.

The rule holding unit 14 holds the rules used by the semantic interpretation unit 13. An example of semantic interpretation rules is shown below.
(Rule 1) Even if the word “professional baseball” is not included in the program name, the program information extracted from the program DB includes the name of the professional baseball team and the genre is “sports”. Is determined to be “professional baseball”.
(Rule 2) If the program start and end times in the program information on the web page provided from the HTTP server 3 and the program start and end times extracted from the program DB 4 do not match, fluid organization (occurrence of disaster or accident Therefore, it is determined that the program organization is changed).

  The metadata conversion unit 15 generates metadata based on the result extracted from the program DB and interpreted by the semantic interpretation unit. Here, various information obtained from program information and related program information is included as metadata. For example, not only a part of data extracted from program information and related program information is used as metadata, All can be set as metadata (“program information” = “metadata”). Also, information such as alarm information, update information related to program information update, and the urgency of metadata can be included as metadata.

  The web page reconstruction unit 16 inserts the metadata generated by the metadata conversion unit into the information content extracted from the HTTP server by the web page extraction unit, and generates information content for the mobile phone. An example of the generated information content is shown in FIG.

The semantic interpretation unit 13 interprets the program information extracted from the program DB based on the rules held in the rule holding unit 14, and creates metadata based on the results, thereby receiving the information content. In addition to displaying the metadata on the display, the following exemplified information related to the metadata can be displayed. In order to execute the following information display, an instruction may be described in advance in the program installed in the mobile phone so as to execute an operation corresponding to the transmitted metadata.
(Example 1) When the metadata "professional baseball" is received, the symbol mark of the team that competes in the professional baseball program corresponding to the metadata is displayed on the mobile phone in the standby state together with the metadata.
(Example 2) When the metadata “fluid organization” is received, for example, “the broadcasting time of the program A of the general television has been changed” is displayed on the display of the mobile phone in a standby state. The purpose is to promote viewing of the program. Moreover, since the possibility that the disaster, the incident, and the accident occurred can be assumed as the reason for changing the broadcast time of the program, it also plays a role of notifying the occurrence of the accident implicitly. Alternatively, the reason why the broadcast time of the program is changed can be explicitly transmitted as metadata and displayed on the mobile phone display in a standby state.
(Example 3) When the metadata “broadcast start time = 13: 30” is received , for example, the alarm time of the mobile phone in a standby state is activated at 13:29, and the start time of the broadcast program desired by the viewer is determined. You can let them know that it has happened. As described above, in the present invention, the metadata and the alarm information can be cooperated by using the control program, thereby notifying the viewer of the start of the broadcast program desired to be viewed.

Next, a specific example of a series of processes of the above-described information content generation system according to the present invention will be described with reference to FIG.
First, the HTTP server 3 is accessed, and program information relating to the broadcast program is acquired from the web page of the HTTP server by the web page extraction unit 11 (step 10). The acquisition timing may be acquired periodically, for example, every hour on the hour, may be acquired at regular time intervals, or may be when program information in the web page is updated.

  A program name is extracted from the acquired program information, and related information related to the broadcast program is acquired from the program DB using the program name as a keyword (step 20).

  Next, the meaning interpretation unit interprets the acquired related information based on the rules held in the rule holding unit (step 30).

  Next, the metadata conversion unit generates metadata related to the broadcast program based on the interpretation result (step 40).

  Next, the generated metadata is inserted into the program information acquired in step 10. Specifically, the metadata generated in step 40 is inserted as a comment sentence of the script of the web page acquired from the HTTP server (step 50).

  In step 50, the reconstructed web page is published to the mobile phone via the communication interface. The timing of acquisition by the mobile phone may be a time set in advance on the mobile phone side, or may be a time when an update is confirmed by checking the update of the web page at an arbitrary time.

  FIG. 6 shows an example of a web page of an HTTP server and an example in which metadata of information content created based on the web page is displayed on the screen of the mobile phone. As an example, on the mobile phone display, as metadata, “05:55 PM” indicating the broadcast start time, “professional baseball” indicating the genre of the broadcast program, and “XX” indicating the battle team name are displayed. The display “vs. ΔΔ” is displayed. In this way, by displaying only metadata that briefly represents the gist of the broadcast program on the screen of the mobile phone, the broadcast program scheduled to be broadcast can be easily and accurately transmitted to the viewer. As shown in FIG. 6, it is also possible to acquire news from a web page and generate information content in which program information and news are posted together.

  Next, an embodiment of a portable terminal suitable for the information content generation system according to the present invention will be described. FIG. 7 is a diagram showing an example of a portable terminal according to the present invention. The portable terminal has functions or means shown in FIG. 7 in addition to various functions as a normal portable terminal. The portable terminal according to the present invention has a communication interface 30 and is connected to the information content generation device via the communication interface and the network. Information content related to a broadcast program transmitted from the information content generation device is acquired by the content acquisition unit 31 and stored in the content holding unit 32. The acquired information content is appropriately controlled by the control information held in the control information holding unit 33. As the control information, for example, when the metadata includes a program start time, an alarm can be generated at or just before the program start time.

  The metadata is extracted by the metadata extraction unit 34 and the content is interpreted by the metadata interpretation unit 35. Furthermore, an acoustic signal is generated from the alarm unit 36 in accordance with the interpretation result of the extracted metadata. Further, the extracted metadata is displayed on the information display unit 37 which is a display.

  FIG. 8 is a diagram showing the operation of the mobile terminal shown in FIG. In this example, it is assumed that the broadcast program is related to a professional baseball broadcast, and an alarm is generated 5 minutes before the broadcast start to instruct the viewer to start the program. In step 20, information content is acquired. In step 21, metadata is extracted from the acquired information content. The extracted metadata is “05:55 PM” as the broadcast start time, “professional baseball” as the genre of the broadcast program, and “match team name” as the program content.

  Next, in step 22, the metadata is interpreted. As an interpretation result, for example, an alarm is sounded 5 minutes before the start of the broadcast start time, and the metadata is displayed on the screen (step 24). As described above, the mobile terminal of the present invention displays the broadcast program metadata on the screen and can notify the viewer of the start of the broadcast by an alarm immediately before the broadcast start time.

  The present invention is not limited to the above-described embodiments, and various modifications and changes can be made. For example, in the above-described embodiments, a mobile phone has been described as an example. However, the present invention is not limited to a mobile phone, and can be applied to a PC and other mobile terminals.

  Further, in the embodiment described above, program information is acquired from the HTTP server, and then the program DB is searched using the program name as a keyword. However, the search of the program DB is omitted, and the meaning of the program information acquired directly from the HTTP server is as follows. It is also possible to create metadata by interpretation.
