Multicasting

I don't know about you, but I agree with this guy, although
we have to realize that it is possible with the appropriate
compression technique to achieve multicasting at the same time as HD.
However, I do think that before a program provider, a
network, a broadcast station, a cable provider, a DBS satellite
provider or an other media platform can label or advertise their
program as "HD", they have to broadcast it in the original aspect
ration and the full 720p or 1080i specification.
Same for television sets.
Since CES won't make or enforce such a rule, the FCC should;
and if the FCC won't, then Congress should.
That would start eliminating the fraud rampant in the industry.
I think it's absurd the FCC can fine for a bad word but not
for fraud in advertising HD.

Best,
Robert

Wade, if the station were to use a compression technique, they would
also have to provide us with decoders. Our recievers only decode a
particular signal.

Robert,
Generally, when stations use excessive compression they still meet the
basic HD spec (16:9 Aspect Ratio{though one could debate if that is a
requirement} and 720p x1280 or 1080i x 1920 resolution). The problem
here is that the stations introduce excessive compression artifacts when
they use additional compression to make room for additional channels.

I also don't understand what you mean "we have to realize that it is
possible with the appropriate compression technique to achieve
multicasting at the same time as HD." Our broadcast standard is MPEG-2
PERIOD. And additional subchannels ALWAYS reduces the quality of the HD
signal.
