[mythtv] [mythtv-commits] Ticket #926: Radio channels for DVB-T

[Michael Freeman]

 my zap2it feed would pull in at least generic listing information for the
music channels for my digital cable company so in theory i could try to map
them out too and live with that if nothing else.

as far as program data  / listings go, the cable companies (at least the
ones around here) all send their data in an out of band channel.
from what i can tell, i'd need to get a QPSK demodulator unit capable of
picking up a 3 MHz wide signal centered around 75.25 MHz  (2.048 mbit / sec
data feed) to even get at the data before testing a decoder addin for
myth...i believe though that all the specs i need would be @ www.scte.org
if someone can tell me where i can get a qpsk demod for under US$700, i'd be
shocked but i just might buy one...if i had found such a device already, i
might have given this a shot.
all the gear i found so far seems to be expensive lab gear, expensive
headend equipment or cheap stuff on ebay in need of an expensive interface
card (such as a rs-449 serial card).
