DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a time division multiplexed data receiving apparatus according to the present invention will be described below with reference to the drawings.

A time division multiplexed data receiving apparatus according to the present invention is constructed as shown in FIG. 1, for example. In this embodiment, the present invention is applied to a television receiver having a function of receiving character multiplex broadcasting using television broadcasting.

The television receiver comprises a tuner section 2 connected to the television antenna 1 and a video signal processing section 3 to which the reception output of the tuner section 2 is supplied, and the television signal is generated by the video signal processing section 3. The video signal is supplied to the character signal processing unit 11 and is also supplied to the cathode ray tube 5 via the signal mixer 4. A control unit 12, a program memory 13 and a character pattern memory 14 are connected to the character signal processing unit 11. A registration memory 15 which is a non-volatile memory such as an EEPROM is connected to the control unit 12.

The tuner section 2 selectively outputs a television signal of a desired channel from the television signals of the respective channels input via the television antenna 1. Here, it is assumed that the television signal is a character multiplex data signal in which character data signals of a plurality of programs are superimposed in the vertical synchronization period by time division multiplexing.

The video signal processing section 3 also generates a video signal from the signal received by the tuner section 2, that is, a television signal of a desired channel. Further, the signal mixer 4 is supplied with a character pattern signal read as a display signal from the character pattern memory 14, and the character pattern signal and the video signal processing unit 3 are supplied.
The video signals from the above are mixed and mixed or switched to be supplied to the cathode ray tube 5. Then, the cathode ray tube 5 displays on the screen an image corresponding to the video signal or the character pattern signal supplied from the signal mixer 4 or the mixed signal thereof.

Further, the character signal processing unit 11 extracts character data signals of a plurality of programs A, B, C, ... Which are superimposed in the vertical synchronization period of the video signal supplied from the video signal processing unit 3. , Character data signals of programs A [weather forecast], B [program table], D [sports result table], F [stock], etc. specified by the control unit 12 are extracted,
The character data that has been subjected to error correction processing and the like is written in the program memory 13. Further, the character signal processing unit 11
Each program A, B, written in the program memory 13
The character data of, for example, the program A designated by the control unit 12 is read from the character data of D, F, and G and supplied to the character pattern memory 14. Then, the character pattern memory 14 reads the character pattern data corresponding to the character data of the program A supplied from the character signal processing unit 11 from a kanji ROM or the like and displays the content of the program A on the video RAM as an image. A character pattern signal is output as a display signal for performing.

The control unit 12 is composed of a microcomputer, receives a selection operation input from the selection operation device 16, and performs the following control operation according to the selection operation input.

In this embodiment, the selection operator 16
As shown in FIG. 2, is provided with a ten key 16A for moving a program, a move key 16B, a selecting key 16C, a registration key 16D for registering a program, and the like.

When the control section 12 receives a program selection input from the ten-key pad 16A of the selection operator 16, the control section 12 superimposes a plurality of video signals supplied from the video signal processing section 3 in the vertical synchronization period. Programs A, B, C
.. from the character data signal of, for example, the character data signal of program D specified by the program selection input by the ten-key 16A, the character data signal of program D is extracted, and the character data is subjected to error correction processing, etc. The character signal processing section 11 is controlled so as to be supplied to the memory 14. By inputting a program selection with the ten key 16A of the selection operation device 16, the plurality of programs A, B, C ...
Any program can be selectively designated from.

When the control section 12 receives a program selection input by the registration key 16D of the selection operation device 16, the control section 12 registers the program being received at that time as a received program, and its channel, program number, page, etc. The registration data indicating the attribute of is stored in the registration memory 15. Here, the registration memory 15 is provided with a fixed area in which the registered contents are not changed and a variable area in which the registered contents can be changed, and is used by most users as programs A and B in the fixed area. A program that seems to be so, for example, a weather forecast or a program guide of character multiplex broadcasting is registered in advance, and a received program arbitrarily selected by the key operation of the selection operation unit 16 is registered in the variable area. .

Then, the control unit 12 gives the control data indicating the received program registered in the registration memory 15 to the character signal processing unit 11 so that the vertical direction of the video signal supplied from the video signal processing unit 3 is supplied. The character data signal of the registered received program is extracted from the character data signals of a plurality of programs A, B, C, ... The character signal processing unit 11 is controlled so as to be stored in the memory 14.

Further, the control section 12 controls the registered contents registered in the registration memory 15 in this manner, that is, the received program, to be displayed as a menu on the screen of the cathode ray tube 5 as shown in FIG. Then, the control unit 12
In response to a move operation input by the move key 16B of the selection operation device 16, control is performed to move the index M for selecting a received program displayed on the screen of the cathode ray tube 5, and the selection operation device 16 is selected. When the selection operation input by the key 16C is accepted, at that time, the control data indicating the received program designated by the position of the index M is given to the character signal processing unit 11 to supply the video signal supplied from the video signal processing unit 3. Character data obtained by extracting the character data signal of the designated reception program from the character data signals of a plurality of programs A, B, C, ... So as to be stored in the character pattern memory 14.
To control.

In this embodiment, among the character data signals of a plurality of programs superimposed on the time division multiplexed data, that is, the vertical synchronization period of the television signal, the program including the character data signal to be received is selectively stored in the registration memory 15. The character data of the program registered and registered in the registration memory 15 is selected from the character data of the plurality of programs and stored in the program memory 13, and the received program registered in the registration memory 15 is selected and selected. By selectively reading the character data of the received program from the program memory 13 and outputting the character data, as shown in FIG.
As shown schematically, only the character data of the program registered in the registration memory 15 is selectively stored in the program memory 13, so that high speed access can be performed without requiring a large capacity memory. It is possible to improve the operability.

Also, by registering in advance a program that most users think will be used, for example, a weather forecast or a program guide of character multiplex broadcasting in the fixed area of the registration memory 15, it is the first user. However, it is possible to use the weather forecast and the program guide of the character multiplex broadcasting extremely easily without requiring a complicated operation.

Further, by displaying the registered contents registered in the registration memory 15, that is, the received program on the screen of the cathode ray tube 5 as a menu, a desired received program can be selected without requiring a complicated operation. .
