[QUOTE="Forgotten Illustrator, post: 47581, member: 17564"] the data steram still has to changed form a frequency(s) to a digital data stearm. you may ask me that, you thought it was already a digital singal? no its not a 1s and 0s transmitted singal. say you wish to get 1010 they just cahnge the phase of the frequency by 30 deg. mind you its more complect them that. this is were the speed and procession is needed. If your using Media portal to watch TV the MPEG-2 is still decoded on the card after coming form the demultiplexer not by the CPU. once again speed is needed for HD bit rates You sound like you unstanded the terms related with this topic, so here a PDF link is used to get my prev post info. it talks about MPEG and want is done on a PCI for DVB plus a HOLE lot of other s**t p.s opps i forgot to add link [url]http://www.cs.ucl.ac.uk/teaching/dcnds/group-reports/2003/2003-akester.pdf[/url] [/QUOTE]
