(not shown) inputs the video signal 1 of the branched TV broadcast, separates the synchronization signal from the video signal 11, and inserts it into the vertical retrace period of the video signal 1 based on the synchronization signal. The control unit 14 separates the teletext signal and sends the teletext data No. 3 that has been subjected to error correction processing to the teletext signal.
supply to.

The teletext data 13 input to the control unit 14 is transmitted to the control unit 1 along with the program number and page number contained in the data 13.
When the storage area of the memory runs out, the oldest data stored in the memory is sequentially erased, and the new data received is stored.

The remote control signal receiving section 20 receives a remote control signal corresponding to the key outputted by key operation of the remote control operating device 21, amplifies it, and supplies the demodulated signal to the control section 14.

The operation signals of the keys provided in the teletext receiver 10 are directly read by the control unit 14 and transmitted to the remote control signal receiving unit 20.
It decodes the signals outputted by the respective processing procedures and outputs the respective control signals according to the corresponding control procedures.

Based on the teletext program number specified by the key input section 19 or the remote controller 21, the control section 4 searches for the designated program number 1 included in the teletext data stored in the memory within the control section.

When the control section 4 searches for a specified program, if a page number is specified along with the program number, the teletext data on the specified page of the specified program is searched, and if the page number is not specified, the latest received and stored teletext data of the specified program is searched. Search for teletext data on the page.

The control section 4 reads out the searched specified teletext data, converts it into a display signal 17 in a format for displaying the same day and evening on a television screen, and outputs it. Predetermined characters and pictures are displayed on the television receiver into which the display signal J7 is input.

While viewing a teletext program, the program being viewed is registered according to the control procedure shown in FIG. 2 by specifying program registration using the key input unit I9 or the remote controller 21.

That is, "program storage" is displayed on the guidance line of the display screen, the number of the program being displayed is confirmed, and the same number is stored in the program registration area in the control section memory.
