CECB XX.99 audio only subchannel boxes?

post #1 of 4
Thread Starter 
Does anyone know what DTV CECBs can decode the audio only subchannels usually located as subchannel 99? (for example 12.99 or 20.99)

This would be an audio service not listed in PSIP which contains reading services for the visually impaired.

It was speculated by rcourtney that this was possibly the rebirth of an SAP newspaper reading service for the blind.

Well, it appears that is the case. After disappearing for several months, 35.99 and 45.99 has re-appeared again today on one of our receivers (An Accurian portable TV), and it does have people reading the Des Moines Register on it. For some odd reason, the Accurian portable is the only receiver we have that can currently receive them, whereas when I first discovered them back in December almost every TV we had could receive them. Perhaps the service is still being tweaked.

Just thought I'd post this as an update to the earlier mystery.

Does anyone know what DTV receivers (preferably a CECB) pick up the X.99 subchannels? Anything besides the Accurian Portable TV?

Our State PBS affiliate runs audio-only reading service for the blind on the 4th sub-channel of their stations, which used to be on a SAP of the old NTSC channel. It maps to n-4, not n-99.

IIRC, when they added the DTV sub-channel, there was an issue with certain tuners not picking up the audio-only channel. Adding an ID video still-frame solved the problem.

I just received info that the Digital Stream DTX9950 can decode this subchannel, but the person who shared this info, does not personally have one of these boxes. Does anyone in Iowa have a DTX9950 that they can use to verify if they can decode the audio portion on subchannel XX.99?
