Reference numeral 13 denotes a data accumulation control unit, and the data extraction unit 1
When the data file with the same file name 3 is stored in the data storage unit, the data file with the same file name 3 is deleted. The newly received data file is updated and stored in the data storage unit, and when the data file with the same file name 3 is not stored, the newly received data file is stored in the data storage unit. A data storage unit 14 stores a data file. Reference numeral 15 denotes a general-purpose TV.
The user selects a program item 1 by pressing a desired program item number 2 button on the remote controller. 16
Is a remote control receiving unit, which receives information of the program item number 2 selected by the remote control 15. Reference numeral 17 denotes a file name conversion unit which holds the conversion table file sent from the data extraction unit 12, refers to the conversion table file, and converts the information of the program item number 2 received by the remote control receiving unit 16 into the file. The file name 3 included in the program item name 1 having the program item number 2 is acquired. Reference numeral 18 denotes a browser control unit that causes the browser to display the data content of the data file having the file name 3 acquired by the file name conversion unit 17. 19 is a browser, a browser control unit 1
The data contents of the data file designated by 8 are displayed.

Next, the operation will be described. First, the tuner 11 can receive a signal superimposed on a broadcast wave from a broadcast station at any time, and receives the transmitted signal whenever there is a transmission from the broadcast station. Here, the broadcasting station broadcasts a data program including one or a plurality of data files, and updates and transmits the contents of the data file several times a day depending on the data program. The data signal is transmitted. The conversion table file is similarly packetized and transmitted. The conversion table file may be transmitted simultaneously with the data file, or may be transmitted separately and independently.

Therefore, the data extraction unit 12 restores the file from the packetized file signal received by the tuner 11 and determines whether the restored file is a data file or a conversion table file. The data is sent to the data accumulation control unit 13. The data storage controller 13 has the same file name 3 as the data file.
It is confirmed whether or not a data file having “.” Is already stored in the data storage unit 14. If already stored, the same file name as the newly received data file 3
And deletes the data file already stored and stores the newly received data file in the data storage unit 1.
Update to 4 and accumulate. Alternatively, when a data file of a newly broadcasted program is newly received and a data file having the same file name 3 as the data file is not stored, the newly received data file is stored in the data storage unit 14. accumulate.

On the other hand, if the file restored by the data extraction unit 12 is a conversion table file, the conversion table file is sent to the file name conversion unit 17 and is held in the file name conversion unit 17. Part 17
When the conversion table file is stored in the storage table, the newly received conversion table file is stored in place of the conversion table file already stored. The conversion table file and the data file have identifiers so that the conversion table file and the data file can be distinguished.

Next, in order to view the data file stored in the data storage unit 14, the user presses the power button of the remote controller 15 to start the browser display. Specifically, when the remote control receiving unit 16 receives the power-on information from the remote control 15 and sends it to the file name conversion unit 17,
The file name conversion unit 17 sends the information on the correspondence between the program item number 2 and the program item name 1 together with the power-on information to the browser control unit 18 from the stored conversion table file, and the browser control unit 18 19 is started to be displayed. At this time, the browser 19 displays the data content of the data file included in the program item having the number 1 which is the smallest program item number 2 (for example, the file names “news / 01 / index.html”, “news /02/index.htm
l ”,“ news / 03 / index.html ”,“ news / 04 / index.htm
l, and a data file having "news / 05 / index.html"), and a correspondence table 21 indicating the correspondence between program item number 2 and program item name 1 is automatically displayed (see FIG. 3). . Further, the user refers to the correspondence table 21 displayed on the browser 19, grasps the program item number 2 corresponding to the desired program item name 1, and stores the program item number 2 in the remote controller 1
Press the 5 button to select. Next, when the user presses a button such as “→” provided on the remote controller, the contents of the data file included in the program item of No. 1 are sorted in ascending or descending order of the number described in the file name 3. Will be displayed. Here, the user presses a button such as “→” on the remote control to sequentially display the files. However, until the user presses the number button, the contents of the data file included in the program item of number 1 are automatically displayed. The numbers displayed in the file name 3 may be displayed in ascending or descending order. When the information of the selected program item number 2 is received by the remote control receiving unit 16 and transmitted to the file name conversion unit 17, the file name conversion unit 17 stores the information of the selected program item number 2 based on the held conversion table file. The file names 3 of all data files included in the corresponding program item name 1 are acquired and sent to the browser control unit 18. The browser control unit 18 looks at the file name 3 of the data file stored in the data storage unit 14 and causes the browser 19 to display the data content of the data file having the file name 3 acquired by the file name conversion unit 17. For example, when the number 3 is selected with the remote control, the browser 19 displays the data files “weather / 01 / index.html” and “weather /
02 / index.html ”and“ weather / 03 / index.html ”are displayed sequentially by the user pressing a button such as the remote control button“ → ”as described above, or are automatically displayed sequentially. You.

Here, as described above, since the conversion table file describes the file names 3 and the like of all data files transmitted from the broadcasting station, it is transmitted once and held on the receiving side. For example, the updated file may be transmitted only when the file name 3 is changed.
It is also necessary to respond to a user who newly starts receiving data broadcasting. That is, since the conversion table file is not held in the receiving device that first attempts to receive the data broadcast, the conversion table file may be received and viewed before the conversion table file is transmitted. A data file of a desired program cannot be selected and viewed based on the file. In order to cope with such a case, it is necessary to transmit the above-mentioned conversion table file from the broadcasting station to some extent frequently. For example, it may be transmitted every hour.

The file name conversion unit 17 has been described to hold a new conversion table file in place of the already held conversion table file when newly receiving the conversion table file. The received conversion table file may be compared with the file already stored, and if they are the same, the file may not be updated or stored. In this case, whether to hold the conversion table file based on the identifier indicating the conversion table file described in the above-described conversion table file and a different file name set for each updated conversion table file Determine whether or not.

The program items indicating the data programs are limited to a maximum of 12 items so as to be compatible with a general-purpose TV remote controller, but are more preferably 7 or 8 items. This is the maximum number of items that can be displayed as being easy to grasp without scrolling when displaying the correspondence table on the browser 19, depending on the size of the browser screen. Alternatively, provide a remote control for data broadcasting,
For example, when a channel button with a number from 1 to 20 is provided, it is possible to set the number of items corresponding to these numbers. In this case, if a high-definition and large monitor is used as a browser, even 20 items can be displayed on one screen in a legible manner.

The conversion table file may be a versatile HTML file used for the Internet or the like, like the data file, but the content described in the conversion table file is displayed as it is on the HTML format browser 19. TEXT
It may be a file or the like. As described above, in the data broadcasting system according to the first embodiment, the conversion in which the file names of all the data files transmitted from the broadcasting station, the program item numbers corresponding to the respective file names, and the program item names are described. The table is transmitted from the broadcasting station as a file, and the receiving apparatus that has received the table displays, on the browser 19, a correspondence table in which the program item numbers are associated with the program item names based on the conversion table. By selecting the program item number using up to 12 remote control buttons with reference to the correspondence table, the data file corresponding to the program item number is displayed on the browser, so that the data file of the desired data program is displayed. Is displayed on the browser 19, a data file to be viewed is checked from a large number of file names displayed on the browser, and a cursor or the like is displayed. The user does not need to perform a browser display operation to select the program, and the user can easily find the number corresponding to the data program from the above correspondence table and press the remote control button of any of the numbers to easily view the program. Can be selected and displayed. In addition, since the number is limited, it is easy to remember. If the user remembers the number, he can press the remote control button without checking the correspondence table displayed on the browser, so that the data can be displayed more quickly. Also, as the remote control button, a channel button provided on a general-purpose TV remote control can be used as it is.

In the data broadcasting system according to the first embodiment, the program item number is input using the remote control button. However, the program item number may be input using the numeric keypad on the keyboard. As in the case of using, data can be displayed on the browser simply by pressing the number.
