Abstract

PURPOSE:To obtain a television receiver which is easily viewed with a desired program at a specified time, by storing the reception start time and the station number in advance. CONSTITUTION:In operating a numeric key 4 and a data key 2 for the program reservation, the reserved information is set in a register 5 and displayed on a display 6. After confirming the content of reservation at the display 6, when a button S is depressed, the content is stored in a memory 10 via a write circuit 9. The reservation can be stored in the memory 10 same as above at random for a plurality of buttons. A processing section 12 replaces the content of the memory 10 in the order of time and stored in a memory 18. The reserved information in the memory 18 is sequentially read in a register 19, and when the data information in the said information and the data representing a clock counter 22 are coincident, a main power 24 of a television receiver turns on via a start section 27 and the reception station number information in the reserved information is given in a tuner 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a television receiver that receives television radio waves.

In a conventional television receiver, when receiving a television program from a desired television station, it is necessary to switch the channel to that television station and then turn on the power switch of the television receiver immediately before the program starts. For this reason, viewers have to be careful about when to turn on the power switch, and to avoid this, many people turn on the power switch at a time earlier than the start of the program. Leaving television receivers turned on during unnecessary hours when viewers don't want them consumes an extremely wasteful amount of power, considering the total number of television receivers in Japan. It turns out. Therefore, the station number (channel number) and reception start time of the TV program desired by the viewer are manually stored in the TV receiver in advance, and reception is automatically started when the input time is reached. This way, you will not miss a desired TV program, and it will also be possible to contribute to energy conservation.

It would be extremely convenient if the numeric keys for selecting channels of television radio waves could be switched and used for inputting reception start time data.

The present invention has focused on the above points, and aims to provide a television receiver that facilitates viewing and listening to desired television programs.

The present invention provides a television receiver having a means for receiving television waves, including a selection means for selecting and specifying the frequency band of the television waves, a specifying means for specifying the reception start time of the television waves, and inputting numerical data. A television receiver comprising numeric keys and switching means, wherein the numeric keys are selectively used for inputting numeric data to the selection means and the designation means.

Hereinafter, the present invention will be explained with reference to the drawings. FIG. 1 is a front view illustrating an embodiment of the present invention, and FIG. 2 is a block diagram illustrating an embodiment of the present invention, in which 1 is a switching key, 2 is a date and time key, 6 is a dot key, 4 is a numerical key, 5 and 19 are registers, 6 is a display section, 7 is a display control section, 8 is a switching section, 9 is a writing circuit, 10° 18 is a memory, 11 is a buffer, 12

1] is a date and time data section, tsuku, j is a control signal, and 42 is a contact point. Some recent television receivers have a channel selection section that is removable from the television receiver so that channels can be switched by remote control. This is a method of controlling the connection between the channel selection section and the television receiver through ultrasonic waves, infrared rays, etc. FIG. 1C1'' is a front view of an embodiment of the channel selection section using this method. . The channel/channel selection section shown in Figure 1 is about the size of a pocket calculator, and by pressing number key 4, the desired TV/TV station can be selected.This point is the same as the conventional one. be. In the present invention, if a viewer wants to receive reception from 12 o'clock on channel 6, for example, after pressing the reservation button R, pressing the number key 4 "3", the channel number ( 6) will be displayed. Next, after pressing the switching key 1, if the number keys 4 rIJ, r2J and the date and time key 2 ``hour'' key are pressed, (12 o'clock) is displayed on the date and time display section b1.

Then, when you press the set button S, the channel number and reception start time are stored in the memory, and the built-in time counter is
When the designated time (12 o'clock) arrives, reception of the three channels of television stations will begin.

The power supply unit 24 in FIG. 2 is a power source for the television receiver, and the control circuit related to the present invention is assumed to be supplied from a separate power source (such as a battery). It is assumed that the switching part CH in FIG. 2 is set to the contact (A) side. In FIG. 2, if you press the number key 4 (for example "3") to select the desired television station, channel designation data A (for example 6
) is set in channel part a of register 5. Next, by pressing the switch key 1, the switch CH will be switched to the contact (B) side, so operate the number keys 4 and the date and time key 2 to input the reception start time, for example (12 o'clock). For example, this date and time data B is set in the date and time data section of register 5. The answer of this register 5 is the contact of the switching part 8 (a)
The image is then displayed on the display section 6 by the display control section 7. When the viewer presses the set button S after visually confirming the input data, the write circuit 9 is driven by the control signal, and the data in the register S is written into the memory 10. On the other hand, the display on the display section 6 is erased by the control signal. Like this, number keys 4. By operating changeover key 1 and date/time key 2,
Data related to the start of reception of a desired television program can be input at random, regardless of the order of reception start times. If you use small dot key 3 and number key 4 together,
Use of the date and time key 20 can be omitted. The processing unit 12 is the memory 1
The input data D within 0 is read out L7, rearranged in order of reception start time, and stored in the rearranged data D'Th memory 18. The buffer 11 is used as a work area for this process. The 1-application rearrangement data D' is sequentially read from the memory 18 and set in the register 19, but the channel designation data A (3) that was input earlier is stored in the channel section a, and the date and time data B (12 o'clock ) is set in the date and time data field. The counter 22 is a one-time side counter and is driven by the clock pulse CL from the pulse generator 20. When the value of this counter 22 reaches the value at time 12:00, the AND circuit 21 reaches a match, and the control pulse P is then emitted from the starting section 27, and the power switch 26 is turned on. Therefore, the power supply unit 24 enters the operating state. On the other hand, the tuner 14 is supplied with channel designation data (6 channels) and is set to channel "3" by the control pulse P.
A selection is made. This is facilitated by known techniques such as tuning frequency selection. In this way, when the TV program of the desired TV station reaches the input time, the TV program is displayed on the CRT 25.
It will be imaged by By pressing the call button C, the permutation data D' in the memo January 8 can be displayed on the display section B.

As described above, the present invention provides numeric keys for channel selection.
Since it can also be used for inputting reception start time data, it has the advantage of simplifying the operation panel and significantly improving operability.
