  The present invention relates to a data broadcasting display system and a control program therefor, and particularly stores viewing attributes of viewers, identification information of pages viewed, etc., and re-reception of data broadcasting based on such information. The present invention relates to a data broadcasting display system for displaying content reflecting viewer attributes and viewing information, and a control program therefor.

  In recent years, terrestrial digital broadcasting has started, and data broadcasting has also started. In this data broadcasting, resources such as BML documents, JPEG, PNG, and binary tables are transmitted by a data carousel transmission method. The data carousel transmission method is a transmission method in which a plurality of files are divided into MPEG-2 sections and repeatedly transmitted, and conforms to the DSM-CC standard.

  In data broadcasting, in order to enable playback of interactive content using broadcast waves, the file group that makes up the content is a data carousel so that necessary data can be acquired even if the viewer operates at an arbitrary timing. Is repeatedly sent. When a screen switching instruction is generated by a viewer's remote control operation, the receiver acquires necessary data and displays it on the screen.

  By the way, each viewer has a favorite content. For example, a certain viewer often watches the weather content of data broadcasting, and another viewer often views the news content. After viewing such desired content, it is likely that there are many cases of switching to another channel or turning off the power. Also, when re-tuning, there are many cases where those contents are viewed first.

  Therefore, when a character broadcast program is called in a television broadcast character program, the called character broadcast program data is stored in the data storage memory of the receiver, and the same character broadcast program is called again. In such a case, a technique for reading and displaying data stored in the data storage memory has been proposed (for example, Patent Document 1).

  An embodiment of the present invention will be described.

  The present invention broadcasts the content data of the data broadcast including a program for storing the viewer's viewing information in the receiver. This program is transmitted together with the content at the beginning of the data broadcasting content, and when it operates on the receiver side, the viewing information stored at the end is read, the page data corresponding to this viewing information is acquired, and this page is displayed. And a program for storing viewing information of the displayed page.

  Specifically, as shown in FIG. 1, content data 10 is transmitted from the broadcasting station 1 using data broadcasting. This content data 10 is transmitted with the content at the beginning of the content of the page display data 11, the page identification information 12, the program 13 for storing the page identification information 12, and the content of the data broadcast, and corresponds to the viewing information stored at the end. And a program 14 for acquiring the data of the obtained page and displaying the page.

  The display data 11 is display data for each page of content, and the display data 11 includes not only a pure image but also text data such as characters and symbols and a program for displaying the text data. The page identification information 12 is identification information for identifying each page, and serves as viewing information for the viewer.

The program 13 is a program that operates on the receiving side so that each time the user selects and displays (transitions) a desired page from the content, the page identification information 12 of the page is sequentially stored in the storage unit 21. is there.
Further, the program 14 is a program that operates to acquire the display data of the page corresponding to the last stored page identification information 12 from the data broadcast and display the page of the display data at the time of re-viewing.

  The receiving side 2 receives the content data 10 of the data broadcast by the user's channel selection, and the page identification information 12 of the page is stored in the storage unit every time the page is changed based on the program 13 of the received content data 10. 21 is stored.
