I need as much information as I can lay my hands on about video and audio compression. I am involved in a project to compress TV-quality video and speech-quality audio for broadcast transmission on comparitively slow-speed (9600 - 19200 bps) digital links. Ideally, I would like to find a set of algorithms that I can implement in software, with the option of adding hardware compressor/decompressor boards to gain speed at those sites where speed is important. For those sites where the users are happy about a delay, the software should use a compatible algorithm. The head-end station would probably use hardware compression from the outset, if hardware and software are compatible. I realise that different techniques would be required for video and audio. Please feel free to respond about either or both, if you have any ideas (including tricks for audio modulation, perhaps). Unfortunately, our newsfeed is erratic at times, and I don't get all the groups that I have cross-posted to. Please reply by mail, and I will summarise to the above groups if there is much information and any interest. ---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=---=--- Paul Nash Flagship Wide Area Networks (Pty) Ltd paul@frcs.UUCP ...!uunet!ddsw1!proxima!frcs!paul
