Re: <<<MPEG decode of compressed video are examples of data streaming applications in use today. However, data streaming will become more common in the future as DVD and video conferencing are more widely used. These types of programs vary in the amount of memory performance they require, but all generate extensive simultaneous memory activity that consumes a considerable amount of bandwidth.">>> PC100 has a 6.4 gigahertz peak data rate with streaming at about one third of that. That's 6,400 megabits/sec peak and something more than 2,000 megabits/sec continuous. DVD Peaks at 10 megabits/sec and averages 3.5 megabits/sec so a PC100 DIMM can handle about 600 simultaneous DVD channels. The reality is that your PC will be doing other things at the same time, but handling that DVD data stream will use up about 0.0018th of your PC100 memory bandwidth. It's just not anywhere near being anywhere near being an issue. I may not be a visionary, but I know how to compare two numbers and can even tell when one is way bigger, can you? You are being hornswaggled on the "needed for the internet" issue. Dan ========================================================= sel.sony.com As implemented for DVD, MPEG2 encoding is a two-stage process, where the signal is first evaluated for complexity. Then, higher bit rates are assigned to complex pictures and lower bit rates to simple pictures, using an "adaptive," variable bit-rate process. The DVD format uses 4:2:0 component digital video compressed to bit rates with a range of up to 10 megabits per second. Although the "average" bit rate for digital video is often quoted as 3.5 megabits per second, the actual figure will vary according to movie length, picture complexity and the number of audio channels required.
