Description

The present invention relates to a plurality of audio / video (hereinafter, referred to as AV).
Devices such as audio amplifiers (hereinafter abbreviated as AMP), compact disc players (hereinafter abbreviated as CD), video tape recorders (hereinafter abbreviated as VTR), televisions (hereinafter abbreviated as TV)
The present invention relates to an AV control device for controlling an AV system including a video disk player (hereinafter, referred to as VDP) and the like.

2. Description of the Related Art Conventionally, as a configuration of an AV system, the configuration shown in FIG. 7 has been generally used. As shown in FIG. 7, the VDP 72 reproduces a video disc, and transmits an audio signal to the surround AMP 71 and a video signal to the television monitor 70, respectively. Surround AMP71 adjusts the audio signal sent from VDP72,
SP _A 73L, SP _A 73R, SP _B 74L, SP _B 7
4R, SP _C 75L, SP _C 75R (where SP means speaker,
R means right, L means left, and these symbols will be used hereinafter)
Transmit to On the other hand, the television monitor 70 adjusts the video signal sent from the VDP 72 and outputs it to the monitor screen. Conventional AV
To achieve a surround effect in a system,
Speakers are installed at two places, front and rear, and the normal left speaker L and right speaker R sound are output to the front speakers, and LR is output to the rear speakers (LR is the output of the left speaker and the right speaker). Surrounds to output the sound after performing the operation of
AMP was processing. As a result, the sound after the LR calculation is performed at the center of the reverberation sound whose phases are shifted between L and R, and the reverberation sound and the like are emphasized and output to the rear speaker. A large speaker can produce natural heavy bass and is suitable for classical music, but the sound image is easily blurred. On the other hand, from the viewpoint that small speakers are difficult to produce natural heavy bass, but the sound image is clear, which is advantageous when emphasizing a stereo feeling or a surround feeling, two or more types of speakers are installed in the front speakers. As a result, in order to enjoy the dynamic sound matched to various AV software, the viewer adjusted the adjustment knobs of the AMP and the television monitor to his / her preference every time the viewer played the software.

Problems to be Solved by the Invention However, in the AV system having the above configuration, each time the AV software is changed, various setting values such as volume, balance, sound quality, image brightness, shade, color tone, and sharpness are changed.
Using the adjustment switch on the panel of the AV equipment, or the remote control for each AV equipment, or the adjustment knob, etc., must be adjusted to the optimal setting value each time, giving a great deal of complexity to humans, There is a problem that the adjustment itself is not an operation that can be easily and easily performed in a short time. For example, when watching a video, the room is darkened so that the screen is a little dark, if the sound is recorded in Dolby surround, it will be played in Dolby surround, if it is recorded in monaural recording, it will be played in pseudo surround mode Is necessary. Also, when listening to music, listening to jazz, listening to classical music, listening to pop songs, or listening to many other types of songs, tone control and surround mode are different, and these It is very difficult and complicated to make settings corresponding to different types of songs each time. Also, the balance of the left and right rear may be slightly shifted during recording even in a source recorded in Dolby Surround mode, and this shift varies depending on each source. It has to be done every time. In addition, when switching SPs, it is not possible to automatically and optimally set various setting values such as volume, balance, and sound quality suitable for SP efficiency. Was. For example, regarding speaker settings, the efficiency of each speaker is different, and even if the same power is supplied from AMP, a different value can be obtained for each speaker as the sound pressure, for example, 96 dB
In the case of / w / m speakers and 90dB / w / m speakers, there are often situations where settings must be made in consideration of the fact that even if the same power is output from the AMP, the sound pressure is twice as large. It is mentioned that. Also, in the surround mode, even if you adjust the balance of the sound from each speaker correctly with the AMP volume to properly reproduce the wonderful stereoscopic effect and sound image of the source, you can change the SP or the position where people listen If has changed,
A situation has arisen in which the above adjustment has to be performed again. In addition, a situation has arisen in which settings cannot be made in response to changes in the number of listeners.

The present invention solves the above-mentioned problems, and
An object of the present invention is to provide an AV control device capable of centrally controlling an AV device remotely.
