Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a teletext broadcast program reservation device for pre-registering a frequently received program number when a teletext is received by 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 tuned to a desired channel by a tuning unit 2, demodulated into a primary color signal by a signal processing unit 3, and transmitted to a signal switching unit 4. To display a normal TV signal on the CRT 14, the primary color signal as it is may be sent to the CRT 14,
When the remote control signal obtained by the remote control light-receiving unit 5 selects the teletext, the television control unit 6 sends the video signal from the signal processing unit 3 via the bus line 7 and the teletext reception control unit 15
To be sent to the signal processing unit 11 of FIG. 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 received by the remote control light receiving unit 5, decoded by the teletext control unit 10, and the information corresponding to the program number is read out from the buffer RAM 12 and controlled by the display control unit 8 to control the video signal. It is stored as a video signal in a RAM (V-RAM) 9. At this time, depending on the character information command, kanji ROM1
Read Kanji data from 3 and store it in V-RAM9. V
-The video signal stored in the RAM 9 is transmitted to the signal switching unit 4 in accordance with 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 and transmits text information to the CRT 14. Project to 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. However, when a desired teletext program is selected, a three-digit number is usually transmitted to the remote control transmitter. It is necessary to enter the program number or the like, and it is necessary to keep this program number or write it down to something, and there is a disadvantage that it is not possible to quickly find the program to be watched. 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, a teletext program reservation device of the present invention connects a television control unit and a teletext control unit via a bus line, and operates input signals obtained by a remote control transmitter or the like. Is decoded once by the TV control unit, and when a program number is input, the channel signal is stored together in the storage means, and a plurality of pairs are stored as a pair of the channel number and the teletext program number. An operation button is provided to make one-to-one correspondence between the information of the pair and the selection input of the remote control transmitter. By operating the operation button, the corresponding pair number is read out from the storage means, and the character is transmitted via the bus line. This is sent to the broadcast control unit. Operation By storing and reading out the program numbers that are frequently viewed by this device, it is possible to easily select a desired program to be viewed and to improve operability. Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an apparatus for realizing a teletext program reservation apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of a remote control transmitter, and FIG. 3 is a functional diagram of a 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, an operation signal from a remote control transmitter shown in FIG. 2 is received by a remote control light receiving unit 5, and all the signals are resolved by a television control unit 6. A teletext control unit 10 is connected to the television control unit 6 by a one-way bus line 7. The processing steps in the television control unit 6 will be described with reference to FIG. In the remote control transmitter shown in FIG. 2, pulse train data (hereinafter, referred to as remote control data) corresponding to the selected button 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 numeric keypad data for teletext, it is temporarily stored in the reservation buffer section of the work RAM 6-5 for three digits. This numeric key data is also transferred to the teletext control 10 via the bus interface 6-3 at the same time.
By inputting the "#" button after the ten-key operation, a teletext program number is selected. Note that the channel number of the television signal currently being received is also temporarily stored in the reservation buffer unit. Actually, this storing operation is performed at the time of channel selection. On the other hand, after ten-key operation or "#"
When the “reservation” button is input after the button operation, the program enters a reservation standby state for the currently selected program number. In this reservation standby state,
The program number stored in the reservation buffer unit can be displayed on the CRT 14. Next, "Reservation 1" to "Reservation 4"
When any one of the buttons is input, the channel number and the teletext program number temporarily stored in the reservation buffer section are written in the corresponding positions of the reservation number storage means 6-6. Once written, the reservation standby state is released. The reservation number storage means 6-6 is a battery backup or a non-volatile memory or the like, which is stored even after the power of the television receiver is turned off. Hereinafter, in this example, it is possible to make a reservation registration of pair data of four types of channel numbers and program numbers in the same procedure. After the reservation registration, the operator simply presses the buttons of "reservation 1" to "reservation 4".
Teletext control unit 10 through bus interface 6-3
Then, the control data is transferred to and the character 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. Effect of the Invention As described above, the present invention allows a desired teletext program to be called by one operation only by registering the desired teletext program once, thereby greatly improving operability. is there.
