前記信号処理手段は、入力したオーディオ信号をマルチチャンネルのオーディオ信号に変換する信号処理回路と、
変換されたマルチチャンネルのオーディオ信号を各チャンネル毎に圧縮する圧縮回路と、
圧縮した各チャンネル毎のオーディオ信号にチャンネル識別子を付加するチャンネル識別子付加回路と、
チャンネル識別子を付加したマルチチャンネルのオーディオ信号を前記複数のスピーカ装置のうちいずれか一つのスピーカ装置へ送信する送信手段とを備えたことを特徴とするマルチチャンネル再生装置。A multi-channel playback device that inputs an audio signal, processes the input audio signal by a signal processing means, supplies the processed signal to a plurality of speaker devices, and outputs the same.
The signal processing means includes a signal processing circuit that converts an input audio signal into a multi-channel audio signal ;
A compression circuit that compresses the converted multi-channel audio signal for each channel;
A channel identifier adding circuit for adding a channel identifier to the compressed audio signal for each channel;
A multi-channel playback device, comprising: a transmission unit configured to transmit a multi-channel audio signal to which a channel identifier is added to any one of the plurality of speaker devices.
前記マルチチャンネル再生用スピーカ装置は、再生するチャンネルに対応するチャンネル識別子を設定する識別子設定手段と、
受信した圧縮されたマルチチャンネルのオーディオ信号から、前記識別子設定手段で設定したチャンネルのオーディオ信号を抽出し、抽出したオーディオ信号を伸張して再生し出力するスピーカ駆動手段と、
受信した圧縮されたマルチチャンネルのオーディオ信号を再送信する送信手段とを備えたことを特徴とするマルチチャンネル再生用スピーカ装置。A multi-channel playback speaker device that receives a compressed multi-channel audio signal with a channel identifier added thereto and outputs the audio signal ,
The multi-channel playback speaker device includes identifier setting means for setting a channel identifier corresponding to a channel to be played back;
Speaker driving means for extracting the audio signal of the channel set by the identifier setting means from the received compressed multi-channel audio signal, decompressing and reproducing the extracted audio signal ;
A speaker device for multi-channel reproduction, comprising: transmission means for retransmitting the received compressed multi-channel audio signal.
