How does descriptive audio work? This is the additional descriptive audio for the visually impaired that describes what is happening on the screen ("A man wearing a trenchcoat walks into a dark room"). For the Seattle PBS station that I tune with clear QAM, I sometimes get this audio, especially Masterpiece Mystery. Do I have the wrong audio stream/PID selected in the channel mapping? Or, did the station do something wrong? (Would not surprise me.) I can't verify that this does or does not happen when I watch the channel on TV, I'm pretty sure it doesn't, though.
The channel scan has 2 audio programs for this channel, ID'd as:
106.1 KCTSHD*(000) A:2049
106.1 KCTSHD*(000(AC3)) A:2050
I have the one ID'd as AC3 mapped, all the other channels only have a singe audio program. Should I have the non-AC3 one mapped? I don't need AC3 as I don't use surround sound.
Thanks for the insight folks.
