Too bad. I haven't tested it here on Cox in Gainesville but maybe 5 years
ago in Detroit on Comcast I dual recorded a number of HD programs
simultaneously from both OTA and cable and, after stripping each to a
single MPEG-2 stream, they appeared identical both in bit rate and video
quality. At that time I was convinced Comcast was neither rate shaping or
re-encoding.
Five years ago, perhaps Comcast in Detroit had no need or the technology to
rate shape or re-encode. Today it is much easier and cheaper, and the
digital tier is getting very full.
The FCC has ruled that cable companies cannot rate shape OTA HD any further
than they do to their other HD channels. There is no requirement, however,
for a bit-for-bit delivery of OTA HD to cable consumers.
