Here's Clarke post about Qcom......Thanks for the info Clarke... F - Cinecomm background at: exchange2000.com In addition it should be noted that Qualcomm has several patents in the area of video compression and one is a very early patent that is heavily reference by later patents in the area. This implies that it is a key patent and that they have a fair amount of expertise in it. The technique described in the patent is similar to the technique used in MPEG (Frame is broken up into blocks which are transformed using a DCT. High frequency stuff is not sent. Off the top of my head, if I remember correctly it also describes a basic method for interframe compression, but of that I am less sure.) Clark PS Long time no see. Haven't been in CUBE in a long long time. PPS A while ago I asked on the CUBE thread if anyone knew how processing intensive MPEG decompression and compression was. How many transistors does a decompression chip have? A compression chip? Do you know? I know that there are folks here that can answer your Q about # transistors Clarke. Anybody have the IBM patent link on their bookmarks who can look up these Qcom video patents for us?
