2. Description of the Related Art A teletext system is a system for repeatedly transmitting program data corresponding to each of various kinds of programs in the form of digital signals during a specific horizontal scanning period in a vertical retrace line period of a television signal. .

On the receiving side, all the transmitted program data are extracted by a signal extraction operation, and the extracted program data are temporarily stored in a buffer memory. Next, the receiver designates a predetermined program from the plurality of transmitted programs, and the program data corresponding to the designated program is read from the buffer memory. The read program data is written in the presentation program memory. The program data stored in the presentation program memory is divided into display data and additional sound data, the display data is displayed on the screen, and the additional sound data is output as voice.

By the way, in recent years, a large number of programs have been transmitted to one broadcasting station for teletext broadcasting. However, the program number of the transmitted program is not specified except for the table of contents program (000 #) and subtitle program (999 #). Therefore, the receiver can view the teletext using the conventional teletext receiver. In order to obtain the desired information, for example, the following operation procedure is required.

The receiver first selects and presents a table-of-contents program, searches for a desired program from the screen, and confirms the program number of this program. After that, this number is keyed in, and the program of the desired information is viewed by selecting and executing it.

Therefore, when the receiver views the teletext, the above-mentioned complicated operation is required to obtain desired information, which is inconvenient.

Therefore, the present invention has been made in view of the above problems, and can be operated by a simple structure, and a teletext reception can be performed without complicating the program specifying operation by the receiver. The purpose is to provide a device.

[0009]

According to the teletext receiving apparatus of the present invention, a plurality of program data inserted in a vertical blanking period of a television signal are extracted, and all the extracted program data are buffered. By storing the program data in the memory and designating the program number, the program data corresponding to the program number is read out from the program data stored in the buffer memory, and the read program data is displayed in the program memory for presentation. A teletext receiver that stores and transfers the program data stored in this presentation memory to an image memory, and presents the program data stored in this image memory on a screen. An operation unit is provided, and using these operation units, the index data of the program desired by the receiver from the program number group and the start program number and the end program number are displayed. A simple read-out key input means for recording or reading, and a first memory means for registering and storing the start program number, the end program number and the registered headline data inputted by the read out key input means. A second memory means for fetching and storing the program index data stored in the buffer memory, and the corresponding registered program number groups are respectively input by the simple read key input means to the first memory. The program number group read out from the means is read out from the second unit.
Means for performing processing using the program index data stored by the memory means and sequentially presenting from the start program number to the end program number of the program number group.

[0010]

In the present invention, the headline data and the start program number and the end program number desired by the receiver are input and set from the program number group of the received teletext by using the simple reading key input means. It can be registered by the memory means. Also, the transmitted program index data can be stored by the second memory means.

Thus, the programs from the start program number to the end program number can be sequentially presented only by operating the simple read key input means.
