Take any MPEG stream (which is already compressed) which has a little bit of action, and a little bit of macro blocking from that compress it and re-compress it. Then put it through a device to insert comercials (which will re-re-compress it) and those macro blocks suck even more.

This is almost the same as what happened(s) when you copy a copy of a copy of a videotape. Won't turn out to well. This is why the Broadcasters get a VERY high bitrate feed from the network then to thier things to it before they compress it down.

Unfortunatly, the providers give the cable and satellite guys what they give them, and it isn't high bitrate. You want better product? Call your programers (hb0 etc) and complaing.]]>Apr 5th 2008 11:22AMhttp://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/http://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/Apr 5th 2008 12:05PMhttp://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/http://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/Apr 5th 2008 12:30PMhttp://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/http://www.engadgethd.com/2008/04/04/hd-compression-goes-under-the-microscope/Apr 7th 2008 2:16PM
