Seems strange that PBS would be the channel and not the TV Guide channel which I get through my local cable company. The reason I ask Is If your sure that there the channel I was thinking of connecting them to verify they are sending the signal or not.
Your cable company has nothing to do with the TVGOS data stream, other than rebroadcasting it on a channel they carry. In fact, they have the right to strip it out, if they so choose -- there's a landmark FCC case between Gemstar and I think Time Warner about this you can Google. I am not aware if TVGOS data is being broadcast in the VBI (vertical blanking interval) of the TV Guide channel. Maybe it is, but it's not included on my cable lineup. Check out this link which explains PBS:http://www.pbsnationaldatacast.com/Analog_Network.htm
Don't forget that TVGOS is designed for an OTA input as well as cable. People using an antenna won't have access to the TV Guide channel. PBS is the closest thing to universal channel (and they could always use the extra money), which is why the VCR manufacturers implemented the auto clock set feature, which is also based on PBS VBI data. Local network affiliates may have cut deals with Gemstar to broadcast the data stream, but that varies by market.
Since eventually the analog NTSC broadcasting will go away, does anyone know if TVGOS as it exists in our HM94 TV's is capable of operating with channel-specific guide data which may be transmitted in ATSC PSIP?
