To make the issue more interesting, some broadcasters use a 35Mbit 
downlink in a format less compressed than MPEG2 which allows doing 
some image manipulation without adding much artifacts.  They then 
convert the image to their desired HD format and compress on the fly. 
That is what my local ABC station does.  My local NBC station seems to 
forward the data more literally so that there is an obvious MPEG 
transition when switching from local content to network content (e.g. 
severe MPEG pixelation when switching to the Tonight Show).

There is no telling what cable providers are doing.  They have already 
been jumping through hoops to obtain more "digital" channels from 
their available bandwidth.
