So in an ideal world, it would be great to have a pci add-on card, that does not only do assisting, but actually does all the features, so by sending the compressed stream directly to board, and it does all the un-compressing and uses its own internal memory (on board memory) to do movement of uncompressed streams and doing additional post processing on the picture. Similar to a FF-card but independent of DVB and can do *High 10 Profile (Hi10P)*.
I know it is a pipe dream. So in a perfect world it would be nice to have something like the following: pci board with a sigma 8635 chip for decoding (o rsomething similar) and a S3 chip for post processing (or something similar) onto one board with a s-video out, HDMI out, spdif out/audio out. And can do 1920x1080 progressive scan PAL @ 25 or even 50 frames per second. So that we can be ready for when BluRay hits the market (affordable). the output can either be by using a X driver or frame buffer driver. Oh well the wish list goes on :) So the end user can then upgrade the output device when he/she can afford an upgrade to a HD output device and of course don't forget all have Open Source drivers hehe. Tomorrow I will wake up and realise the truth of it all... To the future of open source!
