Shane:
Per our discussion on today's call, the requirement to be able to direct
different audio content to different devices is captured in VD-11:
[DV-11] Support the simultaneous playback of both the described and
non-described audio tracks so that one may be directed at separate
outputs (e.g., a speaker and
headphones).
While I believe directing these separate audio media types has
always been the intent of DV-11, I think we can clarify and
further refine this requirement. Here's a suggestion:
[DV-11] Support the simultaneous playback of both the
video description track and primary audio resource tracks so that either may be
directed at separate outputs (e.g., one to loudspeakers and
the other to headphones). Where a screen reader is present,
also support the ability to keep its audio output separate from
both the described video track and the primary audio
resource tracks.
