Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text broadcast program number reservation apparatus for pre-registering a frequently received program number when receiving a text broadcast with a television receiver.

2. Description of the Related Art In recent years, television broadcasting has multiplexed and transmitted a teletext radio wave to a general television broadcast radio wave as a new medium, and also connected a teletext multiplexing adapter to the television receiver side or built a teletext reception circuit. Provides textual information.

Hereinafter, a teletext signal receiving system will be described with reference to the drawings. In FIG. 4, a radio wave of a television broadcast obtained from an antenna 1 is selected by a channel selection unit 2 into a desired channel.
Is transmitted to To output a normal television signal to the CR 714, the original primary color signal is sent to the CRT 14. However, when the remote control signal obtained by the remote control light receiving unit 5 selects a text broadcast, the television control unit 6 sends the signal via the bus line 7. The signal processing unit 3 instructs the video signal to be transmitted to the signal processing unit 11 of the teletext reception control unit 15. Upon receiving the video signal, the signal processing unit 11 detects character information in the video signal and stores it in the buffer RAM 12.

On the other hand, the program number selected by the remote control transmitter is decoded by the teletext control unit 10 received by the remote control light receiving unit 5, and the character information corresponding to the program number is read out from the buffer RAM 12 and controlled by the display control unit 8. The video signal is stored in the V-RAM 9. At this time, depending on the instruction of the character information, the kanji data is read from the kanji ROM 13 and stored in the V-RAM 9. The video signal stored in the V-RAM 9 is transmitted to the signal switching unit 4 in response to a command from the display control unit 8, and the signal switching unit 4 sends out a signal from the teletext reception control unit 15 to the CRT 14 to transmit text information. Display on CRT14. To select a program number, it is usually necessary to select and transmit a three-digit number from a remote control transmitter or the like.

Problems to be Solved by the Invention Teletext program numbers are usually selected by three-digit numbers, but whenever a desired teletext program is selected,
Usually, it is necessary to input a three-digit number with a remote control transmitter or the like, and it is necessary to memorize this program number or write it down to something, and there is an inconvenience that a desired program cannot be found quickly.

The present invention has been made in view of this problem and makes it easy to select a program number of a teletext broadcast.

Means for Solving the Problems In order to achieve this object, the teletext program number reservation device of the present invention connects a television control and a teletext control unit with a bidirectional bus line and obtains the information by a remote control transmitter or the like. The input operation is decoded once by the television control unit and transferred to the teletext control unit via the bus line. Remote control transmitter, etc. are provided with a program number reservation standby button and several reservation buttons, read the program number from the teletext control unit via the bus line by inputting the reservation standby button, and control the TV with the channel number in pairs It is stored in the storage means of the unit. The storage means stores a plurality of information of the pair. By pressing the reservation button, the reserved pair information reads out the corresponding pair number from the storage means and sends it to the teletext control unit through the bus line.

Operation With this device, by storing and reading out the program numbers that are frequently viewed, it is possible to easily select a desired program to be watched, thereby improving operability.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a method for reserving a teletext program number in one embodiment of the present invention. FIG. 2 is a remote control transmitter.
FIG. 3 is a functional diagram of the television control unit. The procedure for extracting the character information from the television radio wave input from the antenna 1 and projecting the character information on the CRT 14 has already been described in the conventional example, and a description thereof will be omitted.
In FIG. 1, operation signals from a remote control transmitter shown in FIG. 2 are received by a remote control light receiving section 5 and all are decoded by a television control section 6. A teletext controller 10 is connected to the television controller 6 via a bidirectional bus line 7.

The processing steps in the television control unit 6 will be described with reference to FIG. After the pulse train data corresponding to the button selected in the remote control transmitter shown in FIG. 2, the remote control data is referred to as remote control data and is input to the arithmetic processing unit 6-2 via the remote control interface 6-1. In the arithmetic processing unit 6-2, processing is performed according to the procedure programmed in the instruction ROM 6-4.

If the remote control data is related to teletext, it is transferred to teletext controller 10 via bus interface 6-3.

When the "reservation" button of the remote control transmitter of FIG. 2 is input,
3 via the bidirectional bus line 7 from the teletext control unit 10
The digit program number is transferred to the television control unit 6. The television control unit 6 temporarily stores the channel number being received and the three-digit program number in the reservation buffer of the work RAM 6-5, and enters a reservation standby state. In this reservation standby state, the program number stored in the reservation buffer can be displayed on the CRT. Next, when any one of the buttons "reservation 1" to "reservation 4" is input, the channel number and the program number of the teletext temporarily stored in the buffer are written in the corresponding positions of the reservation number storage means 6-6. . Once written, the reservation standby state is released. This reservation number storage means 6-6 is stored even after the power of the television receiver is turned off by a battery backup or a nonvolatile memory.

In this example, the pair data of four types of channel numbers and program numbers can be reserved and registered in the same procedure.

After registering the reservation, the operator simply presses the buttons of "reservation 1" to "reservation 4", and the arithmetic processing unit 6-2 sequentially reads the channel number and the program number from the corresponding positions of the reservation number storage means 6-6. -3, the control data is transferred to the teletext control unit 10, and the text information of the teletext program number of the desired channel is received.

Although the above embodiments have been described by taking as an example a case where the remote control transmitter is used, the same operation and effect can be obtained even if the operation buttons are provided directly on the television receiver body.

As described above, according to the present invention, a desired teletext program can be called by one operation only by registering the desired teletext program once, thereby greatly improving the operability. It is.
