Raw HDTV is about 1.2Gbps. RAW NTSC SDI bitstream is a few hundred.
The 6 and 19.8 are already compressed. Obviously putting more horsepower
to the compression you can achieve smaller data rates. However applying
for example MPEG4 instead of MPEG2 for 1080i or 720p ups the computational
requirements beyond current consumer state of the art.

75% is enough.
