影像声音输出装置、声音输出装置、影像声音再生装置、影像声音数据再生系统及影像声音数据再生方法
Abstract:
(i)在任意的装置之间单向发送影像数据和声音数据；(ii)在所有的装置之间双向发送控制消息；且(iii)在能够从接收装置向发送装置单向传输发送装置的声音再生能力信息的情况下，用于收发影像数据和声音数据的装置的连接成为有效，TV(31)对DVD记录器(10)发送包含AV放大器(21)的声音再生能力信息的控制消息(30M3)，在DVD记录器(10)及TV(31)被连接，以使从DVD记录器(10)向TV(31)单向发送影像数据和声音数据的情况下，且，在TV(31)及AV放大器(21)被连接，以使声音数据通过其他的网络从TV(31)被输出到AV放大器(21)的情况下，TV(31)在发送控制消息的情况下，禁止DVD记录器(10)进行使用了单向传输的声音再生能力信息的再次传输。
Abstract(English):

In the case where (i) audio-video data is unidirectionally transmitted between any device, where (ii) control messages are bidirectionally transmitted between all of the devices, and where (iii) a connection between the devices for transmitting and receiving the audio-video data becomes valid when unidirectional transmission of audio reproduction capability information of the reception device fromthe data reception device to the data transmission device becomes available, the TV (31) includes the audio reproduction capability information of the AV amplifier (21) to the control message and transmits the control message to the DVD recorder (10) (30M3), and in the case where the DVD recorder (10) and the TV (31) are connected such that the audio-video data is unidirectionally transmitted from the DVD recorder (10) to the TV (31), and where the TV (31) and the AV amplifier (21) are connected such that the audio data is output from the TV (31) to the AV amplifier (21) through another network, the TV (31) does not re-transmit the audio reproduction capability information to the DVD recorder (10) using the unidirectional transmission when transmitting the control message.
