Abstract

PURPOSE:To select a desired teletext program by providing a key pad having keys selecting an information field, a CPU circuit having a storage means and a program selection means, and a memory storing a teletext channel selection data so as to allow the receiver only to operate the key of the key pad selecting an information field. CONSTITUTION:There are six keys to a key pad 9 to select information fields and five program numbers at maximum are registered to each information field. The user depresses a key selecting an information field of the key pad 9 to select a teletext of a desired information field. A signal from the key pad 9 is inputted to a CPU circuit 11 by a remote control reception circuit 10. Then a program selection means 15 reads a teletext channel selection data stored in a memory 13. The read teletext channel selection data is fed to a teletext decoder 12 to command the reception of a relevant program. Moreover, a video and audio changeover circuit 5 is changed over to display the teletext pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a teletext broadcast receiver.Prior art In recent years, various television multiplex broadcasts have been considered in order to effectively utilize broadcast radio waves. , one of them,
Teletext broadcasting, which allows text and graphic information such as news and stock market conditions to be displayed on the screen of a television receiver, has already been put into practical use.

Hereinafter, a teletext receiver capable of receiving teletext as described above will be described with reference to the drawings.

FIG. 5 shows the configuration of a conventional teletext receiver. In FIG. 5, 1 is a block diagram of the teletext receiver, and 9 is a keypad for giving instructions to the teletext receiver 1. 2 is an antenna, 3 is a channel selection circuit, 4 is an audio demodulation/amplification circuit, 6 is a brightness amplification color demodulation circuit, and 5 is a video/audio switch for switching between the television video/audio signal and the video/audio signal output from the teletext decoder 12. circuit, 7 is an audio output circuit, 8 is a video output circuit, IO is a remote control receiving circuit,
12 is a teletext decoder, 11 is a remote control receiving circuit lO
This is a CPU circuit that controls the channel selection circuit 3, the teletext decoder 12, and the video/audio switching circuit 5 according to the key data input from the CPU circuit.

The operation of the teletext receiver configured as described above will be described below.

FIG. 2 is a detailed diagram of the keypad 9. When watching TV broadcasts, it is the same as a conventional television receiver,
By pressing the keys "0" to "9" on the keypad 9, an instruction is sent to the channel selection circuit 3 to select the television broadcast to be received.The television signal selected by the 0 channel selection circuit 3 is audio demodulated and amplified. The signal is processed by the circuit 4 and the luminance amplification color demodulation circuit 5, passes through the video/audio switching circuit Is5, and is output as an audio signal and a video signal from the audio output circuit 7 and the video output circuit 8, respectively. On the other hand, if you want to watch teletext, press the r letter J key on keypad 9.
Instructs the PU circuit 11 to switch to teletext mode. The CPL1 circuit 11 controls the teletext decoder 12 to extract a character signal from the television signal selected by the channel selection circuit 3, and processes it to extract the video signal and audio signal of the teletext. Furthermore, the CPU circuit 11 controls the video/audio switching circuit 5 to input the video signal and audio signal of the teletext broadcast to the audio output circuit 7 and the video output circuit 8, and output the video signal and video signal of the teletext broadcast as the audio signal and video signal, respectively. To select a program, the CPU circuit 11 and teletext decoder 12 are instructed by pressing keys "0" to "9" on the keypad 9.

Problems to be Solved by the Invention However, in the above-mentioned teletext receiver, in order to watch teletext, you press the "character" key to enter the character mode, and then press the keypad 9's "0" to "9"
For example, if you want to watch a news program and know that there are 100 news programs, you can press the 100# key four times to watch the program. However, if you didn't know the number, you couldn't easily watch the program. Furthermore, the operation of pressing a key four times was troublesome.

In view of the above-mentioned problems, the present invention provides a teletext reception keypad that allows a desired teletext program to be selected by simply pressing a key for selecting an information field once.

Means for Solving the Problems To achieve this object, the teletext receiver of the present invention includes a keypad having a key for selecting an information field, a memory for storing character selection data, and a character selection in the memory. It is comprised of a storage means for storing station data, and a program selection means for reading out the character selection data stored in the memory and selecting a teletext program.

Effect: With this configuration, character selection data that instructs to display teletext for each information field is stored in the memory by the storage means in advance, so that when a key for selecting an information field on the keypad is pressed. In addition, the program selection means reads out the text selection data stored in the memory and makes it possible to select teletext programs for each information field.

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a teletext receiver according to an embodiment of the present invention.

In FIG. 1, 13 is a memory for storing character channel selection data, 11 is a C having storage means 14, and program selection means 15.
In the PU circuit, 9 is a keypad with keys for selecting information fields. 2 is an antenna, 3 is a channel selection circuit, 4 is an audio demodulation and amplification circuit, 6 is a brightness amplification color demodulation circuit, 5 is a video/audio switching circuit, 7 is an audio output circuit, 8 is a video output circuit,
10 is a remote control receiving circuit, 12 is a teletext decoder,
The configuration is the same as that shown in FIG. Figure 3 shows key band 9
With illustrations of news, weather, stocks, music, sports,
A key to select entertainment information areas has been added.

The operation of the teletext receiver configured as described above will be described below. FIG. 4 shows that by the storage means 14,
FIG. 3 is an explanatory diagram of character selection data stored in memory I3. In this example, there are 6 keys for selecting information fields, and a maximum of 5 program numbers can be registered in each information field. This operation is stored in the memo January 3 by the storage means 14. This operation can be arbitrarily set by the user operating the keypad 9.

The user presses the information field selection key on the keypad 9 to select a teletext program for each desired information field. The signal from the keypad 9 is sent to the C
It is input to the PU circuit 11. And program selection means 15
The character selection data stored in the memory 13 is read out. The read character channel selection data is sent to the teletext decoder 12 to instruct it to receive the corresponding program.

Furthermore, the video/audio switching circuit 5 is switched to display a teletext screen.

As described above, according to this embodiment, the keypad 9 having a key for selecting an information field, the memory means 14, the program selection means 5, and a memory for storing character selection data. 13, by simply operating the key to select the information field on the keypad 9,
It is possible to select a desired teletext program.

Effects of the Invention As described above, according to the present invention, the keypad has a key for selecting an information field, a CPU circuit having a storage means, a program selection means, and a memory for storing character channel selection data.
