What will I be able to do with an Audio Return Channel -enabled device?
If your HDTV has a built-in tuner, DVD player, or other digital content source, the Audio Return Channel allows the TV to send audio data “upstream” to your A/V receiver, eliminating the need for a separate audio cable in this type of configuration. Audio Return Channel-enabled TVs can either send or receive audio via the HDMI link, giving you greater flexibility in how you set up your home theater equipment and making a separate upstream audio link unnecessary.
Which audio formats are supported over the Audio Return Channel?
The Audio Return Channel supports all the same audio formats that can be sent through a traditional S/PDIF audio connection, including Dolby Digital, DTS, and PCM audio.
