Abstract

PROBLEM TO BE SOLVED: To provide a mechanism for allowing a receiver itself to determine whether the communication content of a data broadcast to be acquired from a program content can be displayed or not, and allowing only the receiver which can display the communication content to perform access to a content site and to perform automatic posting.SOLUTION: An image display control system is the system where receivers which can display a data broadcast and a content to be distributed from an information distribution device are connectable via the Internet, to a management device for managing the receivers to be permitted to acquire the content. The receiver receives the data broadcast, analyzes the broadcast markup language (BML) script, and confirms the acquisition possible level of the content to the management device based on the BML script. The management device determines whether the receiver is the one which can acquire the content or not. When the acquisition is possible, the receiver transmits the acquisition request of the content to the information distribution device, and displays the requested content and the data broadcast on the same screen.

Description

  The present invention relates to a control program for automatically posting communication contents in a digital broadcasting system and a digital communication system, and a program for managing contents to be automatically posted for each receiver.

  Currently, a digital content providing system is realized, and an interactive service capable of providing “communication content” in cooperation with program content is also realized. In order to provide this interactive service, BML (Broadcast Markup Language) program content is used in digital broadcast services as digital broadcasts distributed by radio waves and broadcasts using communication lines. The BML script included in the data is analyzed by a receiver, and data broadcasting is displayed and linked “communication content” is provided.

  Normally, program content in BML format is broadcast and distributed by multiplexing program data consisting of video and BML data, and viewed using a BML browser provided in a receiver (general television receiver). be able to.

  In this regard, for program content created in BML format, when a BML file to be displayed superimposed on video is requested from the digital broadcasting terminal to the BML server on the center side, information stored in the digital broadcasting terminal (viewer attribute information or Other digital broadcasting terminal information) is also transmitted, and the BML server dynamically creates a BML file based on the information transmitted from the digital broadcasting terminal, so that the center side dynamically responds to the digital broadcasting terminal information. Discloses a mechanism for changing contents (for example, Patent Document 1).

  In addition, the receiver in an environment connectable to the Internet accesses the URI described in the BML script of the received program content, acquires the communication content arranged in the content site connected to the Internet, A mechanism that can be executed has been disclosed (for example, Patent Document 2).

Then, the receiver 400 that has received the program content analyzes the BML script in the program content and inquires of the operation center 200 whether or not the original communication content that can be acquired during broadcasting can be acquired.

  Program content as digital broadcasts such as BS, CS, terrestrial, etc. by digital transmission system using MPEG2-TS from digital broadcasting station 100 that performs data broadcasting including digital data constituting TV broadcasting program (main program) and data broadcasting program Is sent.

  The program content for data broadcasting is composed of image data (still image / moving image), character data, audio data, and a control program (BML script), and is automatically displayed when the program content is displayed on the receiver 400. The communication content URI (link information for acquiring the communication content), the service level for automatically posting the communication content, the communication content automatic bulletin setting BML script shown in FIG. 4, and the communication shown in FIG. A BML script for automatically posting content is included. The received BML script is analyzed by a BML browser provided in the receiver and executed.

  Furthermore, in the present embodiment, the receiver 400, the operation center 200 (management device), and the content site 300 (information distribution device) can be connected via the Internet.

  In the operation center 200 (management apparatus), a service level response server 201 for instructing automatic posting setting of communication contents transmitted from a receiver that has analyzed the BML script, a terminal management database (DB) 202, a service A level management database (DB) 203 is provided. Each database operating in the operation center 200 can be realized by a general information processing apparatus (server).

  The management terminal database (DB) 202 includes specific information (CAS card number, etc.) and name (customer) for identifying the receiver (or recipient) that displays the automatically posted communication content from each customer (owner of the receiver). Name), address, telephone number, link (URI) of advertisement content to be displayed, broadcast period (start time, end time), etc. are obtained and recorded and managed in the terminal management database (DB) 202 of the operation center 200. . The terminal management DB 202 will be described in detail with reference to FIG.

  In addition, the service level management server 203 stores and manages contract information, service level, broadcast period, and the like of automatic bulletin communication content serviced from a broadcasting station that receives digital broadcasting for each customer (owner of the receiver). ing. The service level management DB 203 will be described in detail with reference to FIG.

  The content site 300 is specified by the URI described in the BML script of the program content, stores the BML data of the communication content automatically posted by the receiver in the communication content server 301, and can be distributed on the Internet. Yes. The communication content server 301 operating on the content site 300 can also be realized by a general information processing apparatus (server).

  In the figure, the operation center 200 and the content site 300 are provided at different bases, but there is no problem in managing and operating at the same base.

  The video, audio, and data broadcast demodulated by the viewer's set top boxes (receivers) 401A and 401B are displayed on the viewer's display devices 402A and 402B as broadcast programs.

  The receivers 400A and 400B execute BML for data broadcasting, check specific information (CAS card number, etc.) for identifying the receiver by themselves, and if the conditions described in the received link table are met , Access the specified URI, and acquire and execute BML content on the Internet. If the device is not applicable, normal broadcast content is displayed.

  Next, the data structure of the terminal management DB 202 in FIG. 1 will be described with reference to FIG. The terminal management DB in FIG. 8 is a database that manages receivers that are permitted to receive and display “communication content” from the content site 300 in the present embodiment.

  The terminal management DB includes items of a receiver ID 801, a customer name 802, a customer address 803, a customer telephone number 804, and valid periods 805 and 806 for receiving services. These pieces of information are managed by an administrator terminal of the operation center 200.

The data structure of the service level management DB 203 in FIG. 1 will be described with reference to FIG. The service level management DB in FIG. 9 receives the service, such as the receiver ID 901 of the receiver that receives the service, the broadcast station ID 902 that performs digital broadcasting, the program ID that is broadcast from the broadcast station, the service level 904 of the receiver. It is assumed that the items of valid periods 905 and 906 are provided. These pieces of information are also managed by the administrator terminal of the operation center 200.

  Next, the broadcast facility (broadcast apparatus) 111 of the broadcast station 110 will be described based on the block diagram shown in FIG.

  The main part of the broadcast produced by the video / audio data production device 11 is stored in the video / audio data holding device 12 in a digital data format (MPEG2 or the like).

  BML, which is data broadcast content, is produced by the data broadcast production device 21 and stored in a digital data format in the data broadcast holding device 22. The data broadcasting data that is held can be sequentially updated by the data broadcasting updating device 23 during broadcasting.

  Each program data stored in the video / audio data holding device 12 and the data broadcast holding device 22 by the broadcast information scheduled in advance is converted into one digital data format via the multiplexing device 31, and the modulation device 32 and the transmission device 33. Is transmitted as radio waves.

  Next, the set top box 401 of the receiver 400 will be described based on the block diagram shown in FIG.

  A radio wave received from an antenna (not shown) is selected by a tuner unit 51 and separated by a demodulation unit 52 into video (main video) data, audio (main audio) data, data broadcasting data (BML content), and the like.

  Video (main video) data (such as MPEG2) is decoded by the video / signal processing unit 54 and output as a video signal. Audio (main audio) data (MPEG2-AAC or the like) is decoded by the audio processing unit 53 and output as an audio signal.

  Data broadcasting data (BML content) is expanded on the RAM 59 and executed on the CPU 55 by a browser program stored in the ROM 58 of the set top box 401.

  The set top box 401 receives a signal from the remote controller 61 and executes processing described in a data broadcast control program (script).

  The data broadcast image processed by the browser is combined with the video (main video) by the video / signal processing unit 54 and then output as a video signal. Similarly, the voice of the data broadcast processed by the browser is synthesized with the voice (main part voice) by the voice processing unit 53 and output as a voice signal. Similarly, the video signal and audio signal of the data broadcast processed by the browser can be viewed on the display devices (general television receivers) 402A and 402B.

  Although the configuration of the set-top box 401 and the display device (television receiver) is shown, it may be a television receiver with a built-in set-top box function.

  Further, it is possible to communicate with the Internet using the built-in communication I / F 56 to acquire and execute BML content on the same network.

  The receiver 400 acquires the BML script included in the program content for data broadcasting on the RAM and executes it by the CPU 55. A series of instructions for realizing the subsequent operations are described as a BML script, and the receiver 400 analyzes the script using the BML browser, executes the script, and performs the processes of FIGS.

  Hereinafter, an overview of the overall processing of the present embodiment will be described with reference to FIG. First, the receiver 400 is turned on to receive data broadcast program content from a tuned broadcast station. As described above, the program content includes image data, audio data, character data, and a control program (BML script). The BML script is acquired when the program of this data broadcasting is displayed. The communication content acquisition destination URI and the service level at which the communication content can be acquired are described (1). Next, the BML script of the received data broadcast is analyzed by the BML browser of the receiver 400, and the analyzed program is executed (2). Next, a message (FIG. 10) for confirming whether or not the receiver 400 is a communication content acquisition target is created for the service level response server 201 (3). In the service level response server, the service level at which the receiver 400 that transmitted the message using the receiver ID, broadcast station ID, program ID, etc. described in the message received from the receiver 400 as a key can acquire the communication content. Is confirmed using the terminal management DB 202 and the service level management DB 203. Then, the result is returned to the receiver (4).

  The receiver 400 stores the service level described in the message returned from the server in the storage unit (specifically, NvRAM) of the receiver 400 (5). Thereafter, the receiver 400 extracts a service level value described in the BML script of the received data broadcast (program) and capable of acquiring communication content of the program. Then, the service level value stored in the receiver 400 is compared, and if it is a service level at which communication content can be acquired, a communication content acquisition request is transmitted to the communication content server 301 of the content site 300. (6). The communication content server 301 transmits the communication content to the receiver 400 that has received the acquisition request (7). Finally, the receiver 400 displays the data broadcast (program) and the communication content (8).

  FIG. 11 is a diagram illustrating a display example of communication content in the receiver 400 according to the present embodiment. A program broadcast from a broadcasting station or a program displayed using an Internet line is displayed in a broadcast display area 1101. When the program content including the BML script for displaying the communication content is received, the processing shown in FIGS. 4 to 7 is executed. In step 506, the communication content display area 1102 is displayed for each receiver 400. “Communication contents” of different contents to be provided are displayed.

  Hereinafter, an outline of processing of the video display control system of the present embodiment will be described with reference to FIGS. 4 to 7. First, a communication content automatic bulletin setting flow in the receiver 400 will be described with reference to FIG.

  The communication content automatic bulletin setting processing script shown in FIG. 4 included in the BML script of the program content received from the broadcasting station is executed by operating the remote control button of the viewer.

  First, receiver 400 (assuming a general television receiver) receives a program from a specific broadcasting station in a state where power is turned on. When the “data acquisition button (d button on the remote control)” is pressed during reception, a menu screen displayed for the acquired program is displayed.

  This menu screen is usually processed in parallel so that the receiver 400 can acquire the program from the broadcast station and simultaneously analyze the menu screen information acquired by the BML browser and display it on the receiver display. ing.

  When the menu screen is displayed and selection of “content acquisition” in the menu is accepted, the processing of the flowchart in FIG. 4 (Internet connection determination processing in step 401) is started.

  In step 401, it is determined whether the receiver 400 (specifically, the set top box 401) is connected to the Internet. As a determination method, it is determined whether or not a LAN cable is connected to the communication I / F 56 of the receiver 400. If connected (YES in step S401), the broadcast station ID (network ID) is determined from the CAS card number, which is specific information for identifying the receiver 400, and the SI / PSI information included in the digital broadcast currently being received. ) And the program ID, and an inquiry message to the service level response server shown in FIG. 10 is created (step 402).

  FIG. 10 is a data table showing a configuration example of an inquiry message to the service level response server created in step 402 described above.

  10 includes, for example, a message header 1001, a receiver ID (CAS card number, etc.) 1002, a broadcast station ID (network ID, etc.) 1003, a program ID 1004, a time stamp 1005, and a response status 1006. And

  According to the current ARIB (Abbreviation of Association of Radio Industries and Broadcasting), the message header 1001 indicates that the HTTP version to be installed in the receiver is 1.1. Therefore, HTTP version 1.1 header information is described.

  The receiver ID 1002 indicates identification information for specifying each receiver 400, and corresponds to a CAS card number set in the receiver 400, for example.

  The broadcast station ID 1003 indicates a broadcast station that is broadcasting the program that the receiver 400 is currently receiving. Identification information for uniquely identifying each broadcasting station is set in the broadcasting station.

  The program ID 1004 indicates a program that is currently viewed on the receiver 400. Identification information for uniquely identifying each program is set for the program broadcast from the broadcasting station.

  A time stamp 1005 indicates date and time information when the message is created. Alternatively, it is possible to specify a specific date and time in order to confirm the content at the specified date and time in advance and after the fact. For example, when the administrator of the receiver 400 wants to confirm the contents of the automatically posted communication content displayed in the already broadcasted program, the administrator specifies the past date and makes an inquiry to the service level response server 201. be able to. Data broadcasting requires that content be stored in a storage device for a certain period of time by law, so that it can be verified even after airing. Is possible. Further, when it is desired to confirm the contents of the automatically posted content displayed in a program to be broadcast from now on, it is possible to inquire the service level response server 201 by designating a future date.

  As the response status 1006, when the service level response server 201 receives a message, the service level of the target receiver is determined and a specific value is embedded.

  Subsequently, returning to the description of FIG. 4, in step 403, the receiver 400 passes through the Internet line connected to the communication I / F 56 in order to determine the service level for acquiring its own communication content. The inquiry message described in FIG. 10 is transmitted to the service level response server 201 installed in the operation center 200 in the HTTP format or the like (transition to (1)). Processing for receiving a message and creating a response message in the service level response server 201 will be described in detail with reference to the flowchart of FIG.

  FIG. 7 relates to processing for confirming a service level for automatically posting communication contents at a receiver, which is executed by the service level response server 201 in the present embodiment.

  In step 701, the service level response server 201 receives an inquiry message from the receiver 400 to the service level response server shown in FIG.

  The receiver ID in the received message is extracted, and the terminal management DB 202 is searched as a search key (step 702). It is determined from the search result whether it is within the valid period during which service can be enjoyed (step 703).

  If the result of determination in step 703 is that the receiver 400 that transmitted the inquiry message is stored in the terminal management DB 202 and is within the valid period during which the service can be enjoyed, the receiver ID and broadcast station ID in the message The service level management DB 203 is searched using these as search keys (step 704), and it is determined from the search result whether or not it is within the valid period during which the service can be enjoyed (step 705).

  In step 703, if the receiver 400 that transmitted the inquiry message is not stored in the terminal management DB 202 or is managed by the terminal management DB 202, but is outside the valid period during which the service can be enjoyed, In step 707, it is determined that the receiver is not a target receiver. In step 707, the response status that is a non-service target is set in the response status 1006 item of the inquiry message in FIG. 10, and the result is sent to the receiver 400 that transmitted the message. respond.

  If the receiver does not have a service target level based on the determination result, a response status that is a non-service target is returned to the request receiver. If the receiver has a level, the service level is set to a response status and the request receiver is responded.

  If the value set in the response status 1006 in step 706 or 707 is, for example, the level of two choices of being able to receive the service or not being able to receive the service, “0” is set for the non-service target, and the service is applied. Possible is “1”. In addition, this is not the case when a service is applicable and can be enjoyed with several stages. For example, if the service level goes up step by step, such as regular, bronze, silver, gold, platinum, etc., the values of “1”, “2”, “3”, “4”, “5” are set respectively. I will do it.

  When a response message is returned from step 706 or 707 (transition to (2) in FIG. 4), the process returns to FIG. 4, and the receiver 400 receives the response message transmitted from the service level response server 201 in step S404. (Transition from (2) in FIG. 7), the value of the response status 1006 (service level) included in the received message is the URI described in the BML script included in the program content of the data broadcast from the broadcast station. It is determined whether or not it is an automatic posting target to be acquired (step 405).

  That is, here, the process changes depending on whether the value set in the response status 1006 is “0” or a value other than “0”. If the value of the service level given to the receiver 400 that received the message is a value to be automatically posted (“1” if the service level is determined as “0” or “1”) (step 405). And YES), the fact that the receiver 400 is a receiver capable of automatically posting communication contents is written in a non-volatile memory (NvRAM) (step 406). Here, as described above, the service level value used for the determination may be a binary determination of “0” or “1” or a multi-value determination such as 3, 5, 10 levels.

  According to the processing of FIG. 4, the receiver 400 receives a program from a broadcast station, and determines whether or not the receiver itself is a service receiving target for communication content that can be provided in conjunction with the received program. And the setting for receiving communication contents can be automatically performed. Furthermore, by storing the service level value of the receiver acquired in the response message in a non-volatile memory (NvRAM), even if the receiver tunes to another channel, the service level provided Therefore, it is possible to confirm whether or not communication content can be acquired from the content site each time (specifically, it is executed in step 505 in FIG. 5).

  Next, a process in which the receiver 400 acquires communication content from the content site and automatically posts it will be described in detail based on the flowchart of FIG.

  First, in step 501, the receiver 400 obtains a setting flag for automatic bulletin content temporary suppression from the volatile memory (Ureg / Greg, etc.) of the receiver (step 501), and the temporary suppression setting is stored. (Step 502). The process of writing the automatic posting temporary suppression setting flag in the volatile memory will be described in detail later with reference to FIG.

  If it is not in the temporary inhibition setting state (NO in step 502), the processing from step 503 is executed. If it is temporary inhibition (YES in step 502), the process proceeds to step 508.

  In step 508, the receiver 400 cancels the “automatic content posting temporary suppression setting” stored in the volatile memory (Ureg / Greg, etc.), and the BML script of the program content received by the receiver 400 is released. Acquire and display data broadcasting programs.

  On the other hand, if it is not in the temporary inhibition setting state (NO in step 502), the process proceeds to step 503, and reception that can provide communication content stored in the BML script included in the received data broadcast program content is possible. The service level value of the machine is extracted.

  In addition, the receiver 400 receives the service level value recorded in the nonvolatile memory (NvRAM) in step 406 of FIG. 4 described above (the response message of the service level response server 201 of FIG. 7). Obtained value).

  In step 505, the receiver 400 acquires the service level value of the receiver capable of providing communication content stored in the BML script included in the program content for data broadcasting acquired in step 503, and acquired in step 504. Compared with the service level value (value received by the response message of the service level response server 201 in FIG. 7) recorded in the non-volatile memory (NvRAM), the receiver 400 posts the communication content. It is determined whether it is a target receiver that can be used.

  If the communication content is to be automatically posted, the content site 300 indicated by the URI stored in the BML script included in the program content is accessed to make an acquisition request and stored in the communication content server 301 connected to the Internet. The “communication content” is acquired and displayed on the receiver 400 (step 506). If the service level value recorded in the non-volatile memory (NvRAM) is a value that is not a service target terminal (for example, “0” or the service level is different), from the BML script of the program content, A data broadcast screen related to normal program content is displayed. This BML script is preferably a start document of the BML script in terms of implementation.

  The Startup document here refers to the BML script that is executed first by the BML browser when the channel of the receiver 400 is tuned by remote control operation. This is because the BML script is always executed first at the time of channel tuning, and there is no omission of processing.
