Broadcast data 13 is stored in the order of input.

The teletext data of the program number specified by the key input unit 19 or the remote controller 2 via the remote control signal receiving unit 20 is searched and read out from the data stored in the memory I5, and displayed on the TV screen by the display control unit 17. It is converted into a display signal 18 in a format that can be displayed and output.

A television receiver (not shown) that receives the display signal 18 output from the teletext receiver 10 displays pictures or characters corresponding to the display signal 17 on its screen.

When selecting a teletext program, check the viewing status of the teletext program.
By operating either the table of contents key or cursor key of the key input section 19 or the remote controller 2, the control section I4 selects the table of contents program stored in the memory 15 in the control section 14 according to the control procedure shown in FIG. Read and display the data.

When displaying a table of contents program, a signal for displaying a cursor on any one of the program numbers in the table of contents to be displayed is generated, and the cursor signal is output as a display signal No. 8 superimposed on the signal of the same table of contents program.

Next, use the cursor keys to move the cursor displayed on the program number in the table of contents up or down, and when the cursor moves upwards and reaches the top of the screen, it displays the previous page, and when it moves downwards and reaches the bottom of the screen. displays the next page.

When updating the displayed page, if the displayed page is the start page of a table of contents program when the cursor is moved upward, the specification for upward movement of the cursor can be ignored, and the last page is displayed after the start page. The above operation may be continued.

In the program selection state of the above table of contents program, the program number displayed on the cart when the execution key is manually operated is regarded as the designated program number, and the teletext data of the same program number is stored in the memory 15 in the control section 14. Search and read out the data.

〔Example〕

To explain one embodiment of the present invention, a teletext receiver 10 is connected to a television receiver (not shown), and a video signal 11 branched out from the television receiver is inputted to the teletext receiver 10.

The video signal 1 inputted to the teletext receiver 10 is supplied to the signal separation unit 12, which separates and extracts the teletext signal, and the control unit 14 converts the teletext data in a format that can be handled by a microcomputer. 13 and output.

The teletext data 13 output from the signal separation unit 12 is as follows:
Input to the control unit 13 and memory 15 in the control unit I4
When the memory 15 is insufficient, the stored teletext data is erased in the order of the oldest and the new data received is stored.

The signal receiving unit 20 receives the infrared signal 22 output from the remote controller 21, demodulates it, and converts it into an electrical signal, or the output signal is controlled by the key operation of the key input unit 19 provided in the main body of the teletext receiver 10. Supply to section I4.

Signals from key operations input to the control unit 14 are decoded by the control unit 14, and the data of the teletext program specified by the remote controller 2 or the key input unit 19 is stored in the memory 15 in the control unit I4. The display control unit 17 searches the stored teletext data and displays the read teletext data.
Output to.

The teletext data input to the display control unit 17 is converted into a display signal 1B in a format that can be displayed on a television screen, and outputted, and characters and pictures are displayed on the screen of the television receiver into which the display signal is input. .

By operating the table of contents key or cursor key provided on the key input section 19 or the remote controller 21, the control section 14 inputs the data of the table of contents program stored in the memory 15 in the control section I4 according to the control procedure shown in FIG.
