JPS6018066A - Remote control device using broadcast sound of television, radio and the like - Google Patents

Abstract

PURPOSE:To realize a remote operation of a receiver by actuating a display device, etc. with the signal sound inserted to a part of a broadcast sound. CONSTITUTION:The output of a broadcast device 1 reaches a receiver 12 via a transmission antenna 2 and a reception antenna 11. At the transmission side a signal sound composed by a remote control signal generator 10 by the frequency and its change, code duration, etc. is inserted to a part of a broadcast sound. At the reception side, the signal sound is received by a microphone 14 set close to a speaker 13. Then a driving motor 19 for display device, etc. of the receiver 12 are driven by an amplifier 16, decoder 17 and a control circuit 18.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device for controlling the operation of a display device that uses broadcast audio such as a television or radio.

The present invention utilizes commercials and other parts of TV programs, radio programs, etc., and assembles signals in the form of frequencies, their changes, lengths, intermittences, changes thereof, and combinations thereof, so as to be integrated into the programs. The purpose is to control the operation of the display device installed on the receiver side.

To explain the present invention with reference to the drawings, in FIG. 1, for example, a control signal 003 is inserted into a part 002 of a commercial between programs 001 in a form that blends into the music of the commercial. FIG. 2 is a block diagram of the present invention,
The output of the broadcaster 01 becomes a radio wave by the transmitting antenna 02 and reaches the receiver 12 via each receiving antenna 11, or directly as an electric signal or an optical signal in the case of cable broadcasting. On the broadcasting station side, microphone 03 and tape recorder 04
, record player 05, time signal device 06, etc. are sent to the broadcasting machine via the adverb and keynote 07.

In the case of a television station, a camera 08, a video recorder 09, etc. are also added to this list.

Within the range that can be modulated and received by the remote control signal generator 010 according to the present invention, the format is based on frequencies and their variations, lengths and shorts, intermittents, variations thereof, combinations thereof, etc. using sounds that do not interfere with the progress of programs such as commercials, within the range that can be modulated and received by the remote control signal generator 010 according to the present invention. The assembled signals may be directly broadcast via sub and main keys, or may be recorded on the tape recorder 04 or video recorder 09 at the time of program creation, and then broadcast together with the program when the program is sent out.

On the receiver (((( side), the radio waves or signals received directly from the antenna 11 or the line are received by the receiver 46 12, and the audio is transmitted by the speaker 1.
If it is television from 3 onwards, Eirin will be played on a cathode ray tube 14 or the like.

The program audio received and reproduced may include a remote control signal 003 directly or recorded and reproduced by the remote control signal generator 010. The signal 003 received and reproduced therein is received by a microphone 14 placed close to the speaker 13 of the receiver 12 or sent via an earphone plug 15 to a gain-adjustable constant output amplifier 16.
The signal is amplified by a control signal decoder 17 using a band pass filter or the like, and is selected by a control circuit 18 to operate a motor of a display device, a buzzer, a lamp, etc. 19.

If the display device including 14 to 19 is placed close to or connected to a receiver such as a television using the remote control device configured as described above, various control signals can be controlled by the control signal 003 included in the program 001 commercial 002, etc. It is expected that display @19 will be activated to attract the interest of the receiver and will be effective in preventing a drop in viewer ratings during commercial broadcasts.

FIG. 1 is a time chart of the program, and FIG. 2 is a block diagram.

Claims (1)

[Claims] A remote control device that inserts a signal sound into one part of the broadcast sound of television, radio, etc. as necessary, receives the four part sound through a microphone or earphone jack, etc., and controls the operation of a display device, etc. with the signal. .
