    • A multi-channel audio system using a wireless transmission network used in a home theater includes: a master decoding an input multi-channel audio stream, outputting the decoded multi-channel audio stream, extracting a predetermined audio stream supported by a slave from the input multi-channel audio stream, and transmitting the extracted audio stream by wireless; and the slave transmitting information on an audio stream supported by the slave among a multi-channel audio stream to the master, receiving the extracted audio stream by wireless, decoding the received audio stream, and outputting the decoded audio stream. Accordingly, by extracting only data necessary to a slave and transmitting the data, a multi-channel audio system using a wireless network in which data is transmitted by saving a data bandwidth in a wireless communication environment in which a bandwidth of transmitted/received data is limited.
    • 使用在家庭影院中使用的无线传输网络的多声道音频系统包括:主解码输入多声道音频流,输出解码的多声道音频流,从输入端提取由从机支持的预定音频流 多声道音频流,以及通过无线传输所提取的音频流; 从机将多频道音频流中的从属支持的音频流的信息发送到主机,通过无线方式接收提取的音频流,解码接收到的音频流,并输出解码的音频流。 因此,通过仅提取从机所需的数据并发送数据,使用无线网络的多声道音频系统,其中通过在发送/接收数据的带宽为无线通信环境中保存数据带宽来发送数据 有限。
