Description

  The present invention relates to a broadcast receiving terminal, a program information management server, and a broadcast receiving system that receive broadcast waves such as a digital data broadcast service and an IP broadcast service.

  Meta information (program network ID, service ID, broadcast time, program name, event ID, etc.) related to a program is added to a conventional digital broadcast or IP broadcast service. On the other hand, WWW (World Wide Web) is widely used in the Internet world. This is a system in which information (content) described in hypertext called HTML is transmitted from a server via the Internet, and anyone in the world can access it. In an HTML document, not only text but also multimedia information such as audio and images can be handled by pointing to its presence (pointer or tag), and also describing the text structure such as chapters and sections. (Structured). Further, it has a feature that can describe the presence of resources in the network in a format called URL. By describing a pointer to a URL, it is possible to browse from one resource on the Internet to another and browse. Furthermore, XHTML is a redefined definition of the XML feature that allows users to define multiple tags themselves. By using this XHTML document, it is possible to structurally describe arbitrary meta information, and particularly necessary information can be described as necessary. Further, the micro format is based on HTML (XHTML), and the metadata of the page can be expressed by describing it directly on the web page using a predetermined simple syntax.

  Here, in the following Patent Document 1, a technique in which the concept of hypertext is applied to a broadcast service is proposed. In the technique described in Patent Document 1, a broadcasting station broadcasts character information that expresses information on the contents of a main broadcast in a hypertext format in a sub-broadcast that is broadcast together with the main broadcast. Using a dedicated receiving terminal that can receive broadcasts and sub-broadcasts, only the desired information that matches the preset conditions is extracted and recorded from the character information obtained by receiving the sub-broadcasts. Therefore, the contents of the broadcast can be selected and selected more finely than before.

  As described above, according to the technique described in Patent Document 1, the broadcast station broadcasts the contents of a program (main broadcast) as hypertext and receives it with a dedicated receiving terminal, so that the listener can receive the service. You can receive the offer. However, there are currently services that provide other contents linked to the contents of the program by text multiplex broadcasting, but there are services that provide the contents of the program itself by text multiplex broadcasting using hypertext. Not done. For this reason, the technique described in Patent Document 1 (particularly the receiving terminal) has a problem that it cannot be realized by using a currently provided service (existing service).

  In addition, since the recorded character information is closed to the dedicated receiving terminal that actually recorded, it is not taken into consideration when the stored HTML document is edited on another terminal and information about the program is added. There was a problem.

  The present invention has been made in view of the above, and can be realized by using an existing broadcast service, and information on a desired program among currently broadcast programs can be obtained by a general web browser. It is an object of the present invention to obtain a broadcast receiving terminal, a program information management server, and a broadcast receiving system that are generated in a viewable / editable format.

  In order to solve the above-described problems and achieve the object, the present invention is a broadcast receiving terminal capable of receiving text multiplex broadcasting, and when receiving a program specifying operation for instructing generation of program information from a user. , Program related information acquisition means for extracting character information related to the program from the multiplexed text broadcast wave of the program indicated by the program specifying operation, and program information which is information about the program based on the extracted character information.

This system includes a broadcast receiving terminal 1, a program information management server 2, and a program information editing terminal 3. Each of these devices is connected to a network and can communicate with each other.

  In the system of FIG. 1, a broadcast receiving terminal 1 is a digital broadcast receiving terminal, and when receiving a digital broadcast wave transmitted from a broadcast station, displays it as an image. In addition, based on a program designation operation from the user, the program information related to the designated program is described in a markup language, and the obtained program information is transmitted to the program information management server 2.

  The program information management server 2 generates program information associated with the user of the broadcast receiving terminal 1 and updates the held program information based on the program information received from the broadcast receiving terminal 1. The program information editing terminal 3 is connected to the program information management server 2 and displays a desired program information page among the program information pages held therein using a web browser. Further, the program information page is edited in accordance with an instruction from the user who is viewing the program information page.

  FIG. 2 is a diagram illustrating a functional configuration example of each device configuring the system illustrated in FIG. As shown in FIG. 2, the broadcast receiving terminal 1 includes a broadcast receiving unit 11, a demultiplexer 12, a display unit 13, an input processing unit 14, a communication processing unit 15, a program related information acquisition unit 16, an XHTML generation unit 17, and a control. The unit 18 is provided. The program information management server 2 includes a communication processing unit 21, a user information management unit 22, a program information page generation unit 23, a program information page management unit 24, and a control unit 25. The program information editing terminal 3 is a terminal that is connected to a network and can communicate with the program information management server 2 and includes a general web browser 31 that can interpret the XHTML language.

  In the broadcast receiving terminal 1, the broadcast receiving unit 11 receives a digital broadcast wave via an antenna. The demultiplexer 12 separates the digital broadcast wave received by the broadcast receiving unit 11 into a program data stream and other data. The display unit 13 converts the received broadcast wave into a displayable format and performs screen display processing. The input processing unit 14 receives an operation from the user. The communication processing unit 15 performs communication processing with the program information management server 2. The program related information acquisition unit 16 is displaying on the display unit 13 from a digital broadcast wave and an EPG (Electric Program Guide) after the program data stream is separated by the demultiplexer 12 in response to an input from the user. Information related to the program (network ID, service ID, broadcast date, broadcast time, event ID, station name, program name, etc.) is acquired. The XHTML generation unit 17 corresponding to the program information document data generation unit generates program information (XHTML file) described in the XHTML language based on the information acquired by the program related information acquisition unit 16. The control unit 18 manages the overall processing control flow of the input processing unit 14, the communication processing unit 15, the program related information acquisition unit 16, and the XHTML generation unit 17.

  In the program information management server 2, the communication processing unit 21 transmits and receives program information to and from the broadcast receiving terminal 1 and the program information editing terminal 3. The user information management unit 22 manages user information of the broadcast receiving terminal 1 registered in advance. The program information page generation unit 23 generates and updates a program information page based on the XHTML file of program information transmitted from the broadcast receiving terminal 1. The program information page management unit 24 manages the program information page generated by the program information page generation unit 23 and the user information managed by the user information management unit 22 in association with each other. The control unit 25 performs processing control of the communication processing unit 21, the user information management unit 22, the program information page generation unit 23, and the program information page management unit 24.

  Subsequently, the broadcast receiving terminal 1 generates program information (XHTML file of program information) described in the XHTML language and transmits it to the program information management server 2 until the program information editing terminal 3 edits the program information. The processing procedure will be described with reference to FIG. FIG. 3 is a diagram showing an example of the overall operation of the system shown in FIG.

  In operation in an environment where digital broadcast waves can be received, the broadcast receiving terminal 1 receives and displays the digital broadcast waves (step S1), and the user views them. At this time, the user operates the broadcast receiving terminal 1 as necessary to perform a program designation operation (step S2). For example, while viewing a broadcast program, a program is designated by performing an operation such as pressing a specific button.

  Here, when the broadcast receiving terminal 1 has a recording function and program information can be acquired from the stored content, the stored content may be specified by a program specifying operation. In addition, content that can be browsed using a communication function, such as a VoD (Video on Demand) service, can be specified if program information (URL, program name, etc.) can be acquired. Good.

  When the program specifying operation is executed in step S2, the broadcast receiving terminal 1 executes the process according to the operation content and generates program information. Specifically, in the broadcast receiving terminal 1, the program-related information acquisition unit 16 separates the program data stream by the demultiplexer 12, and the obtained digital broadcast wave (digital broadcast wave after the program data stream is separated) And the program related information (network ID, service ID, broadcast date and time, broadcast time, station name) about the program designated by the program designation operation is acquired from the EPG (step S3). Next, the XHTML generating unit 17 receives the program related information acquired by executing step S3, and generates an XHTML document (XHTML file) indicating the program information based on the program related information (step S4).

  Here, the XHTML document generated in step S4 will be described. FIG. 4 is a diagram showing an example of an XHTML document (program information) generated by the XHTML generation unit 17. Specifically, the program name is “Ramen Special”, the network ID is “5”, and the service ID is “10”. ”, An example in which the broadcast date is“ September 5, 2008 ”, the broadcast time is“ 13: 0 to 15:00 ”, and the broadcast station is“ Ox broadcast ”. In this example, program information is expressed using the class attribute of each tag element. For example, an element group included in an element <div class = “tvevent”> represents information of one program, an element having a class = “eventname” attribute is a program title, and an element having a class = “eventinfo” attribute is Program information included in digital broadcasting, elements with class = "eventdate" attribute are broadcast date, elements with class = "eventtime" attribute are broadcast time, elements with class = "eventch" attribute are broadcasting stations Show.

  Returning to the description of the operation shown in FIG. 3, after executing step S <b> 4, the broadcast receiving terminal 1 transmits the user information of its own terminal (MAC address, user ID, password of the broadcast receiving terminal 1) to the generated XHTML document. It is added and transmitted to the program information management server 2 (step S5). For example, the XHTML generation unit 17 performs processing for adding user information to the XHTML document. The communication processing unit 15 may perform this.

  When the program information management server 2 receives the XHTML document to which the user information is added from the broadcast receiving terminal 1, the program information management server 2 makes an inquiry about the user information using the received user information (step S6). For example, the user information management unit 22 performs the user information inquiry process. Then, in the program information management server 2, when the process of step S6 ends, the program information page management unit 24 searches for the program information page using the received user information (step S7), and associates with this user information. When the program information page is not found, the program information page generation unit 23 newly generates a program information page corresponding to the user information. When the program information page is found, the processes after step S8 are executed. That is, when the program information page corresponding to the user information is not found, the program information page generation unit 23 generates the program information based on the XHTML document (program information) received from the broadcast receiving terminal 1 and the user information added thereto. Create a new page. On the other hand, when the program information page corresponding to the user information is found, the program information page generation unit 23 analyzes the XHTML document received from the broadcast receiving terminal 1 (step S8), and further reflects the analysis result on the program information page. Then, the program information page is updated (step S9).

  Here, FIG. 5 is a diagram showing a description example of the program information page. The program information page is generated by classifying each program information of the XHTML document generated as a result of each user of the broadcast receiving terminal 1 performing a program specifying operation in the past. FIG. 5 shows an example in which the user A of the broadcast receiving terminal 1 registers two pieces of program information. These pieces of program information are described by elements having a “tvevent” class attribute as shown in FIG. The program information page is described in XHTML and can be browsed using a general web browser. Thereafter, each time the program information management server 2 receives an XHTML document describing program information from the broadcast receiving terminal 1, the program information management server 2 specifies program information to be updated based on the added user information, and specifies the specified program information. Is added to the XHTML document. Alternatively, a new program information page is generated.

  On the other hand, when the program information editing terminal 3 satisfies a predetermined condition, such as when receiving an instruction from the user, the program information editing terminal 3 executes the series of processes described above to generate / update the program information page. It connects to the program information management server 2 that is being executed as needed. Then, the user information (user ID, password) is designated and a request is made to transmit the program information page (step S10). When a program information page transmission request is received from the program information editing terminal 3, the program information management server 2 makes an inquiry about the specified user information (step S11). The program information page management unit 24 searches for a program information page corresponding to the user information (step S12). When the search is executed and the program information page is found, the program information page management unit 24 returns the XHTML document of the program information page to the program information editing terminal 3 (step S13).

  When receiving the XHTML document of the program information page as a response to the request in step S10, the program information editing terminal 3 interprets and displays the received XHTML document (step S14). After executing this step S14, when the user of the program information editing terminal 3 performs an editing operation on the displayed program information page (for example, adding a comment to the program information, pasting a link to related information, etc.). (Step S15), the program information editing terminal 3 transmits the operation information to the program information management server 2 (step S16). The program information management server 2 updates the program information page based on the operation information received from the program information editing terminal 3 (step S17). The program information page generation unit 23 performs the update process. When the update process ends, the program information management server 2 retransmits the updated program information page to the program information editing terminal 3 (step S18). The program information editing terminal 3 displays the updated program information page.

  FIG. 6 shows a more specific operation example in the system of the present embodiment that executes the above operation. FIG. 6 is a diagram showing an operation example of the broadcast receiving terminal and the program information management server. In this example, when the user of the broadcast receiving terminal 1 executes a program specifying operation using the operation interface 19 of the terminal, the broadcast receiving terminal 1 generates program information described in the XHTML language for the specified program. . At this time, program information including (recorded) information on the time at which the program designating operation is executed by the user is generated. By recording the time when the operation was performed, the user can record that he / she was paying attention to a specific scene of a program, and by viewing the program information page, You can easily recall the scene.

  The program information generated as a result of the program designation operation being executed is transmitted to a program information management server (not shown), and the program information management server shows the program as shown on the basis of the received program information. Generate an information page. The program information page shown in FIG. 6 is a display example when the XHTML document exemplified in FIG. 5 is interpreted by a web browser.

  The broadcast receiving terminal 1 may have a function equivalent to that of the program information editing terminal 3 and may adopt a configuration capable of editing the program information held in the program information management server 2.

  As described above, in the system according to the present embodiment, the broadcast receiving terminal 1 is instructed to record program information for a predetermined program (when the program designating operation in step S2 is performed), the existing Program related information (network ID, service ID, broadcast date / time, broadcast time, station name) is extracted from the digital broadcast wave and EPG transmitted from the broadcast station in the broadcast service of XHTML document based on this. The program information management server 2 that is generated and connectable via a network manages the generated program information. As a result, information (program information) about a desired program being broadcast can be viewed and edited by a general web browser (a web browser capable of interpreting the XHTML language) that can be used in an existing broadcasting service. A broadcast receiving terminal generated in a format can be obtained. Further, the program information once stored in the program information management server 2 can be displayed / viewed / edited by a network device (program information editing terminal 3) equipped with a web browser capable of interpreting the XHTML language.

Embodiment 3 FIG.
FIG. 9 is a diagram illustrating a configuration example of the program information management server according to the third embodiment. The program information management server of the present embodiment replaces the control unit 25 of the program information management server (see FIG. 2) of the first embodiment with a control unit 25a, and further includes a program information analysis unit 201 and a program statistics page generation unit 202. Is added. In FIG. 9, the same components as those in the program information management server of the first embodiment are denoted by the same reference numerals. In the following description, in order to distinguish from the program information management server of the first embodiment, the program information management server of the present embodiment is referred to as a program information management server 2a. The configuration of the broadcast receiving system including the program information management server 2a of the present embodiment is the same as that of the first embodiment (see FIG. 1). That is, the program information management server 2 in FIG. 1 is replaced with the program information management server 2a, and the broadcast receiving terminal 1 and the program information editing terminal 3 are the same as those in the first embodiment.

  In the program information management server 2a, the program information analysis unit 201 analyzes the program information managed by the program information page management unit 24. The image quality of the image output from the display unit 13 is controlled. The program statistics page generation unit 202 generates a program statistics page based on the result of the program information analysis performed by the program information analysis unit 201 at a predetermined timing.

  Next, a detailed operation of the broadcast receiving system according to the present embodiment, specifically, an operation in which the program statistics page generation unit 202 generates a program statistics page will be described. However, the description of the same part as the operation in the broadcast receiving system of Embodiment 1 is omitted.

Here, terms newly used in the description of the present embodiment are defined as follows.
Program statistics page: A Web page describing statistical information about a specific program obtained by analyzing information on a specific program described in a plurality of program information pages, and is generated as an XHTML document.
Program statistics page browsing terminal: A terminal for browsing a program statistics page having a built-in Web browser capable of interpreting an XHTML document, and accesses the program information management server 2a via the network shown in FIG. The program information editing terminal 3 may have the function of the program statistics page browsing terminal.

  FIG. 10 is a diagram illustrating an example of the overall operation of the broadcast receiving system according to the present embodiment. In addition, the same step number is attached | subjected to the process same as the process included in FIG. 3 shown in Embodiment 1. FIG. Description of each of these steps is omitted.

  In the broadcast receiving system of this embodiment, the broadcast receiving terminal 1 and the program information management server 2a update the program information page in the program information management server 2a by executing steps S1 to S9 described in the first embodiment. To do. That is, when the broadcast receiving terminal 1 receives a program specifying operation from the user (step S2), steps S3 to S9 are executed. On the other hand, the program statistics page browsing terminal 4 receives an operation from the user and, if it is a program statistics page browsing instruction for a specific program, transmits a program statistics page corresponding to the browsing request from the user. In this way, the program information management server 2a is requested (step S21). At this time, the program statistics page browsing terminal 4 designates program information (network ID, service ID, broadcast date / time, broadcast time, station name).

  In the program information management server 2a that has received the request in step S21, the control unit 25a first inquires and acquires program information page management unit 24 for program information that matches the specified content (step S22). The program information acquired at this time is XML format data shown in FIG. However, in addition to the data in FIG. 4, it is assumed that the time when the program specifying operation is performed (the time when the program specifying operation is received) is included. In step S22, all program information that matches the specified content is acquired without distinguishing the user (user) of the program statistics page browsing terminal 4. That is, even program information associated with user information different from the user information of the program statistics page browsing terminal 4 is acquired if it matches the content specified in step S21.

  In the program information management server 2a, when step S22 is executed, next, the program information analysis unit 201 receives and analyzes the program information acquired in step S22. Specifically, the broadcast time of the program is time-divided in units of several minutes, and the number of times that the program designating operation is performed in each time slot obtained by time division is calculated. That is, based on the time when the program specifying operation included in the program information is performed, the execution frequency of the program specifying operation is totaled for each time zone (step S23). For example, the broadcast program from 13:00 to 15:00 is divided into 12 every 10 minutes, and the number of pieces of program information for which program designation operations have been performed for each 10 minutes is totaled. The total number of program information in the first 10 minutes (from 13:00 to 13:10) is the number of program information that has been designated 20 times, and the next 10 minutes (from 13:10 to 13:20) Five times, and so on, are counted every time zone (every 10 minutes) so that the last 10 minutes (from 14:50 to 15:00) is 10 times. The program information analysis unit 201 further analyzes in which time zone many program designation operations have been executed based on the counting results in step S23 (step S24).

  Next, the program statistics page generation unit 202 generates a program statistics page for the program specified in step S21 based on the analysis result in step S24 (step S25). Then, the generated program statistics page is transmitted to the program statistics page browsing terminal 4 (request source of program statistics page) via the control unit 18a and the communication processing unit 15 (step S26).

  When the program statistics page transmitted in step S26 is received, the program statistics page browsing terminal 4 displays it (step S27).

  FIG. 11 is a diagram showing an example of a program statistics page generated by the program information management server 2a. In FIG. 11, the program statistics page browsing terminal 4 designates “Ramen special feature” and requests transmission of the program statistics page, and the program information management server 2 a that has received the request, displays “Ramen” from all the program information pages to be managed. All program information pages that match the “special feature” are identified, and a program statistics page is generated. “Ramen special feature” is designated by program information (network ID, service ID, broadcast date / time, broadcast time, station name). In addition, the “Recommended Scene Ranking Column” on the program statistics page is determined by the “Everyday Hourly Attention Graph” at the bottom. The “everyone's attention level graph by time” is the number of times that the vertical axis program designation operation is performed with respect to the horizontal axis time analyzed in the above-described designated program analysis process (the process of step S24 in FIG. 10).

  As described above, in the system according to the present embodiment, when the program information management server 2a is requested to transmit a statistical page for a predetermined program, the request content is selected from all the stored program information. The program information corresponding to is identified, and the time when the program designation operation is performed is analyzed for each identified program information, and the analysis result is transmitted to the requesting terminal (program statistics page viewing terminal) . As a result, the user of the program statistics page browsing terminal can obtain a scene with high attention (time in the program) for a predetermined program (a program designated from among programs whose program information is managed by the program information management server). Can know.
