Raymond - One place where MPEG-2 compression errors show up easily is in fairly dark background parts of an image, particularly if there is a very gradual change of shade or color. But once one knows what to look for, the errors are quite noticible - kind of like that black and white picture that doesn't look like anything recognizable, then suddenly you see a dalmatian against a backdrop of snow. My "coup de gueule" against TV5 is just frustration to see poor "customer service" as concerns the quality of the video and sound but the main point of my message is that I feel that home delivery of bandwidth will be driven by the entertainment industry - once one can handle music/video, the other data will be a mere rivulet by comparison. And with the bandwidth available, surprising functionality will appear that we can't readily predict at the moment. Ever notice how silly predictions of 20+ years ago look sometimes look? Very few people are close to head on, - such as Alan Kay at Xerox, I recall a Scientific American article where he described laptop computers - he was off by a few orders of magnitude in the memory they'd have on board :-) but he predicted the appliance very accurately, and this was when only the Xerox Star had windows... Oh also - a note about digital cable capacities. On one 6 mHz NTSC cable video channel (8 MhZ for PAL/SECAM in Europe), you can fit about 4 "standard definition" MPEG video channels. One sees the interest for the cable operator when number of channels is a metric but quality of video is not a goal.
