Zusammenfassung:A digital multimedia source device automatically discovers the type of sink device it is sending data to, and based on sink device type automatically selects which audio format to send with the video. For example, lower bit rate audio such as stereo PCM can be sent from a source device such as a DVD player when the DVD player senses that the sink device is a TV with relatively lower audio playback capabilities, while higher bit rate audio such as surround-sound AC3 or super audio CD-DSD can be sent to sink devices such as home theater receivers that have relatively higher audio playback capabilities.
