I recall reading a short time ago that C-cube has just announced initial fabrication of a chip implementing the draft MPEG standard. Can't remember where I saw this though, but it's definitely coming. -- ------------------------------------------------------------------------------ Evan Torrie.

Yes, this was mentioned in several technical rags. They were doing some collaboration with JVC. Also, there is a company called Aware, Inc. in Cambridge, MA doing high speed image copmpression akin to MPEG. They currently have a chipset that does 30 million 8 or 11 bit pixels/s but will soon release a single chip solution capable of 30M 16bit pix/s. Apparently it uses less than 1/5 the operations of competing methods to compress MPEGII images 50:1 with minimal degradation. There is a great article in one of the latest "Communications of the ACM" covering MPEG methods as well as stuff on JPEG.
