Now this is cool, I was just browsing looking for silicon for our products and I found quite a funky little chip from Broadcom. It is the new BCM70020 which describes itself as “a single-chip, full featured, multi-standard audio/video decoder/encoder/transcoder solution targeting volume PC and PC-based consumer electronic applications.”
Not only can it encode HD from either analogue or digital sources, but it can transcode between different MPEG formats and also act as a scaler/down-converter! I think someone in the broadcast industry needs to get their hands on these quickly and create a multi-format scaler/encoder/transcoder matrix device! A few of these, a PCI-E bus and voila there you have a cool transmission ops device.
