JPS6046130A - Tv program reserving device - Google Patents

Abstract

PURPOSE:To simplify TV program reserving operation, by installing a timer key and memory key to a remote control transmitter for selecting TV programs. CONSTITUTION:A switch 2 for channel, sound volume and power supply, a memory key 3 for setting reservation, a timer key 4 for setting power supply holding time, and a display 5 for set conditon of reservation are installed to a remote control transmitter 1. When the switch 2 and keys 3 and 4 are operated, a pulse code assingned from an encoder 6 is generated and tansmitted through a transmitting section 7. At a TV receiver, this signal is received 8 and stored in an RAM 10 after decoding 9, and then, a power supply circuit 11 is connected for a prescribed time by means of a signal from the RAM 10. At the same time, a channel is selected by means of a channel selecting circuit 12. Moreover, by means of a timer pulse from the RAM 10, a dividing ratio setting circuit 14 sets the dividing ratio of the clock frequency of a clock generator 13 and a counter 15 counts the clock. When the counting is completed, a terminate signal is sent to the RAM 10 and disconnection of power supply, selection of channels, etc., are performed.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a program reservation device that controls a television receiver, a video tape recorder, etc. according to a preset order of programs to be viewed.

<Prior art> Conventionally, in the program reservation devices added to the above-mentioned television receivers, video tape recorders, etc., viewers check the channel and start time of the program they want to watch by looking at program listings in newspapers, etc. You don't have to worry about switching channels or turning off the power every time the program starts, and you don't have to worry about missing a program. Information was registered in memory, and the power supply circuit was turned on and off and channels were switched according to the contents of this memory. And the above program reservation is usually 1 [
] as long as or every day, fy-slowly according to which mode;
It was possible to make program reservations.

<Problems to be Solved by the Invention> As described above, electronic equipment equipped with a program reservation device is equipped with a highly accurate clock that counts and displays the commercial power supply frequency or the crystal oscillator frequency. The program records the current time, and when the two match, the electrolytic circuit is interrupted and the channel is switched, so the reservation operation requires at least a "start time".
It was necessary to set the "End time" and "Channel".

Furthermore, the operation switch for making the above-mentioned reservation setting is provided near the clock display section of the main body of the electronic device, and since a plurality of switches are arranged in a row, operation is troublesome.

<Means for Solving the Problems> The present invention eliminates the above-mentioned drawbacks, and in particular uses a timer that counts a predetermined time and continuously switches a plurality of reserved channels at each set time. When setting a program reservation, the memory key and timer key attached to the conventional channel remote controller are used.
To provide a program reservation device that allows program reservations to be made extremely easily by simply adding a switch.

<Example> An example of the present invention will be described below with reference to the drawings. 1st
The figure shows an input device according to the invention, which is provided on a remote control transmitter 1 in order to particularly facilitate manual operation. Here, the operation switch 2 is a conventional channel switch, power switch, and volume switch, and a memory key 3 for setting reservations and a timer key 4 for setting the power retention time in units of 15 minutes, for example, are newly added. It is something. Furthermore, if necessary, a display 5 made of a liquid crystal or the like for displaying the reservation setting status is provided.

FIG. 2 shows a block diagram of the present invention. Reference numeral 1 indicates the remote control transmitter body, and inside this is a
An operation switch 2 connected in an IJ sock shape, a memory key 3 for setting a reservation, and a timer key 4 for setting a power holding time are each connected to an encoder 6, which generates a pulse code signal assigned to each switch, The transmitter 7 emits light pulses such as infrared rays.

The encoder 6 is also connected to the display 5,
The reservation setting status can be displayed. The optical pulse signal of the remote control transmitter 1 is then transmitted to a receiving section 8.
is detected by the phototransistor of the decoder lO
A signal from the remote control transmitter is transmitted via the remote control transmitter to perform a predetermined channel selection operation. At this time, if the memory key 3 is pressed, the R
Writing begins in AM10, and pulses of the channel and timer keys are stored alternately. This R
According to the data written to AMl0, the power supply circuit 11
is connected for a predetermined period of time, a channel is specified to the channel selection circuit 12, and the channel is switched. Also RAMl
A timer pulse is sent from 0 to the frequency division ratio setting circuit 14 to set the frequency division ratio of the clock frequency of the clock generator 13, and the counter 15 counts the clock frequency. When this count ends, RAMI I
A completion signal is sent to , and a counter reset signal is sent back. Then, the operation is performed according to the on/off of the power supply circuit or the next memory contents.

In this device configured as described above, if you want to watch the following program at, for example, 2:30 p.m.: 1. From 2:30 p.m. to 3:00 p.m. 4. h h
2 8ch 3 from 3:00 pm to 3:15 pm, 6ch from 3:15 pm to 4:00 pm The reservation setting operation is as follows: 1a. Press the timer key twice (approximately 15 units each time) 11], You can reserve one program just by pressing the memory key and then pressing 4ch.Similarly, 2a, press the timer key once, 2b, press the memory key and then press 8ch 8a,
Reservations can be easily set by pressing the timer key three times (3+), pressing the memory key, and then reserving 4ch to be suppressed.

The above reservation setting information is encoded and stored in the RAM 1O, the power supply circuit 11 is immediately connected, and the channel selection circuit 12 selects channel 4. and the timer pulse is e.g. 5
Two layers are sent out per second, and correspondingly, the frequency division ratio setting circuit 14 sets, for example, the above-mentioned 1 layer ratio, and in this case, a frequency division ratio of /1800 is set for 30 minutes. Then, the counter 15 is counted until this value is reached, and when it is finished, the end pulse is stored in the RAM.
At the same time, a reset pulse is sent back to reset the counter. When RAM10 receives the end signal, it calls up the next memory, changes the channel to 8ch, and sends out one timer pulse. It's a size.
When the memory is finished, the power supply circuit 11 is cut off.

Therefore, program reservation settings can be easily made from a distance from the television receiver using the two timer keys and memory key attached to the remote control transmitter, and the program reservation settings can be made automatically when one program ends. Since the channel is automatically switched to the next program and the power is turned off when the reservation memory ends, the viewer does not have to do anything after setting the reservation, which is very convenient.
