MPEG artificats in analog cable!? [Oct. 11th, 2005|08:17 pm]

Why the hell do I see MPEG artifacts during commercials on analog cable?

Is the new way to distribute commercials to studios via crappy MPEG files?

Lame. Not that I care about commercial quality much, but I hate this "digital" world being used to lower costs more than increasing quality. Kinda depressing.

I've wondered how far this goes. I used to see artifacts during the hi-motion introduction of iron chef america on foodtv. (I now pull my cable off of whatever Comcast pushes over QAM; it looks like crap)

I bet as the studios convert all their production gear over to HD/digital in prep for HDTV that they just do DA conversion as a final step late in the process, converting on the outgoing (crap) digital signal.

Most studios have used uncompressed digital for a decade or more now. If the artifacts are so bad that you can see them, then they were either caused by compression during transfer (as you guessed) over a satellite link or whatever, or were caused on a comcast video server if they use one for final playout.

In the new world order of HDTV, I see artifacts constantly. The Smallville title sequence, for example, is loaded with blockiness.
