Abstract

PURPOSE: To output a sound under outputting from a speaker at present from a remote controller by providing an input/output voice switching part at a VTR or the like and performing the FM transmission of a signal, which is different from that sound, from a voice source designated by the remote controller. CONSTITUTION: When an operation button 19 provided on a sound remote controller 2 is operated, a microcomputer 20 transmits a remote control code corresponding to the button operation to a remote control transmission part 21. A remote control signal reception part 9 catches an infrared remote control signal and reports its code to a microcomputer 10. The microcomputer 10 instructs switching to the correspondent mode to an input/output voice switching part 3. As a result, a designated audio signal is supplied to an external stereo amplifier 15, the speaker is rung and on the other hand, the designated audio signal is supplied to an FM transmitter 6. Since the sound remote controller 2 receives a radio wave transmitted from an antenna 7 through an antenna 23 and an FM receiver 22, the sound different from the sound of the main speaker can be heard by an earphone 25.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver such as a video tape recorder (VTR), which is provided with a transmitter for transmitting audio, while a remote control transmitter for controlling the receiver is provided with the above-mentioned transmitter. The present invention relates to a device provided with a circuit for receiving an audio signal from a transmitter.

[0002]

2. Description of the Related Art A transmitter for wirelessly transmitting voice as an FM signal is provided on the side of a VTR, while a remote control transmitter for controlling the VTR has the FM transmitter.
A product that receives an audio signal from a transmitter and listens to the sound through a speaker or earphone provided in the remote controller (hereinafter, a remote controller having such a function is referred to as a "sound remote controller") is on the market. .

[0003]

However, the conventional sound remote controller is currently watching (outputting) on the VTR.
I could only listen to the same voice as. For example, when the VTR side outputs a bilingual mode signal (sub audio) from a TV speaker connected to the VTR, switching to select main (main audio),
The main sound was also output from the remote control.

Therefore, it is an object of the present invention to allow a remote controller to output a sound from a sound source different from a sound currently output from a speaker such as a TV set by a receiver such as a VTR.

[0005]

According to the present invention, there is provided a transmitting means for wirelessly transmitting an audio signal from an audio signal source such as an audio multiplexing tuner, an internal audio reproducing system, etc., a remote control signal receiving section, and this receiving. A voice signal from the transmitting unit, and a receiver unit including a first control unit that controls an input / output voice switching unit that receives and outputs a signal from the plurality of signal sources and outputs the signal. Wireless signal receiving means, a voicing means for emitting a voice signal obtained by the wireless signal receiving means, an output voice switching operation section, a remote control transmitting section, and a control according to the operation in response to the operation of the operation section. A receiver including a remote controller with a built-in audio receiver, the remote controller having a second control unit for transmitting a signal from the remote control transmission unit and controlling the input / output audio switching unit.

[0006]

According to the above structure, the receiver such as the VTR can be switched so that the remote controller can output the sound from the sound source different from the sound currently output from the speaker such as the TV.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the essential parts of a VTR and a remote controller for controlling the VTR according to the present invention.
In the input / output voice switching unit 3 of the R body 1, voice signals c and b from the voice multiplex tuner 4 (c is an L channel (main) signal, b is an R channel (sub) signal), a laser disk, etc. Signals l and m from the external device 18 (l is L
Channel (main) signal, m is R channel (sub) signal, tape playback sounds i, j from the VTR tape audio playback system 8 (i is L channel (main) signal,
j is an R channel (sub) signal, which is selected in accordance with an instruction from a microcomputer (microcomputer) 10 and output as g and h from terminals 13 and 14 to an external stereo amplifier 15 or FM transmitter unit 6 It is possible to supply separate or the same audio signal.

The signals n and o output from the terminals 13 and 14 are supplied to the L channel speaker 16 and the R channel speaker 17 as signals p and q through the external stereo amplifier 15, respectively. The audio signal a from the audio switching unit 3 is output from the antenna 7 in the form of an FM broadcast wave as a signal s FM-modulated by the FM transmitter unit 6.

Reference numeral 5 is an antenna for receiving broadcast radio waves,
The signal r caught by this antenna is supplied to the audio multiplex tuner 4.

The input / output voice switching unit 3 can be switched by operating an output voice switching button 19 provided on the remote control transmitter 2, whereby which voice is supplied to the external stereo amplifier 15 and which voice signal is supplied. Can be controlled to be supplied to the FM transmitter 6.

For example, when the audio multi-tuning tuner 4 is receiving a bilingual broadcast, the external speakers 16 and 17 output the main audio (for example, Japanese), and the sound remote controller 2 outputs the sub audio (for example, Japanese). The sequence of operations for outputting (English) is as follows.

First, the output voice switching button 19 of the sound remote controller 2 is operated to select the output mode for the above-mentioned output. Then, the microcomputer 2
Reference numeral 0 denotes an output switching button 19, which recognizes which mode has been selected, and instructs the remote control transmission section 21 to send a remote control code corresponding thereto. The remote control signal t transmitted from the remote control transmission section 21 in the form of infrared rays is caught by the remote control signal reception section 9 of the VTR 1 and the code is transmitted to the microcomputer 10. Then, the code recognizes which mode the microcomputer 10 switches to, and gives an instruction to the input / output voice switching section 3 to switch to the corresponding mode.

As a result, the main voice is output to the external stereo amplifier 15 and the sub voice is output to the FM transmitter section 6. The sound remote controller 2 receives the radio wave transmitted from the FM transmitter unit 6 and the antenna 7 by the antenna 23, demodulates the received signal x by the FM receiver unit 22, and the speaker or earphone 25 through the voice amplifier 24. Since it is output from, the sub voice can be heard by the sound remote controller 2.

Similarly, the sound of the external device 18 or the tape sound reproducing system 8 inside the VTR can be heard by the sound remote controller 2 regardless of the external output (audio signal output to the external stereo amplifier 15).

In this embodiment, since the FM transmitter unit 6 and the FM receiver unit are compatible with monaural signals, the audio signal source (audio multiple tuner 4, external device 18, VTR tape audio reproduction system 8) is stereo. In the case of a signal, the L signal and the R signal are mixed in the input / output audio switching unit 3 ((L + R)
/ 2) and is output to the FM transmitter unit 6 as a monaural signal a.

[0017]

As described above, according to the present invention, in a sound remote controller used for a VTR or TV, it is possible to listen to a sound different from the sound output from the VTR or TV. This can be applied when a TV or VTR is receiving a bilingual (or multiplex) broadcast and there is a person in the family who wants to hear the sound of another person. Since it is possible to listen to the sound of the TV broadcast, it is possible to immediately switch from viewing the VTR to viewing the TV depending on the situation.
