HD compression goes under the microscope


Considering the recent hullabaloo over Comcast and Rogers Cable deciding to (over) compress at least part of their respective HD lineups, Electronic House's latest writeup is particularly timely. It's investigation into HD Lite reveals quite a few tidbits that everyone should know, but often get overlooked in the uproar. Put simply, every high-def channel that gets piped your way is compressed in some form or fashion (that includes you too, Verizon) before it hits the carrier. In other words, just because a signal gets modified before it hits your set doesn't automatically make it HD Lite. Still, there's no doubt that some providers have taken this squeeze too far and compressed signals to the point of noticeability -- that's where the problem emerges. Give the article a read, you'll likely learn a thing or two about nomenclature if all else fails.
