Understood, but is there an actual way to reliably connect a button
event to a labeled audio stream of description? I don't know if we have
any convention like that yet--seems reasonablly straightforward, but
without the convention of labeling it seems like a difficult thing to
implement.

Allen: One of the advances that DTV brings is enhanced audio capability
such as 5.1 channel sound. The ATSC standard also supports multiple
audio streams such as different languages or audio description.

I think some more clear definition about the supplemental audio button
may be helpful.

SAP is really an analog TV concept, right?
As this is on the way out, I'm sure this is a great idea, but does have
limited scope.

it seems like:
A SAP button would be good for analog TV, functionality built in to
audio menus for non analog TV info, and if possible, built-in to set-top
boxes. I'm sure this sounds circular, but the point is that one button
will need to actually perform multiple functions to "turn on" secondary
audio or video-descriptions, dependent upon the path the information is
taking.

Andrew: I understand the requirement to be for two separate buttons --
one for CC and one for audio description. The button for audio
description must be tactile since it intended to enable a blind
individual to toggle secondary audio on/off.

Paul,
I'm confused. So there is not a button for cc and a button for
description? That is two buttons. If it is only one button, which is
it for?
