Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, as multi-channel, the case of using 5.1-channel will be described as an example.

[0023] Embodiment 1

[0024] Fig. 1 is a diagram showing the configuration of a multi-channel audio system according to Embodiment 1 of the present invention. This multi-channel audio system consists of a DVD (digital videodisk) player 10, a small combined stereo (hereinafter referred to as a small combined stereo) 20, a television receiver (hereinafter referred to as TV) 30, a portable MP3 player 40, an AM A plurality of units including an audio amplifier (hereinafter simply referred to as an amplifier) ​​such as an FM radio 50 and a personal computer (hereinafter referred to as PC) 60 are connected by a network 70 .

[0025] The network 70 can be constituted by, for example, a LAN (Local Area Network). Each unit transmits and receives audio data for 5.1-chan...

Abstract

Provided is a multichannel audio system capable of optimizing a plurality of amplifiers on a network for multichannel reproduction to use the optimized amplifiers. A head unit 10 are connected to slave units 20, 30, 40, 50 and 60 through the network 70, the head unit 10 allocates a channel to the slave units 20, 30, 40, 50 and 60 and transmits multichannel data, and the slave units 20, 30, 40, 50 and 60 generate sound signals on the basis of channel data allocated by the head unit 10 in the multichannel data received from the head unit 10.

Description

technical field [0001] The invention relates to a multi-channel audio system and a main unit and a sub-unit applied to the system, in particular to the technology of utilizing multiple audio equipments for multi-channel playback. Background technique [0002] Conventionally, there is known an AV system in which a plurality of AV (Audio Video) devices corresponding to a multi-channel audio system are connected via a network (for example, refer to Patent Document 1). In this AV system, each AV device is configured in such a way that, for example, it is modularized according to functions such as monitor, amplifier, tuner, and speaker. Provides an equal send opportunity serial bus for connection. [0003] The AV system is structured such that functional modules can be freely shared between AV devices. For example, the audio signal of a certain DVD video player can be transmitted to another amplifying unit through the network, and the audio signal can be amplified and output by ...
