What are the current speed numbers (with modern hardware) for ATSC decoding? As a sort of side note I recently aquired access to a 32 cpu Athlon MP1800 cluster. If someone were interested in making it easier to parallelize the decoding we could probably do an real time HDTV experiment.

Just something to think about,

Hi,

I've read your reports on HDTV decoding and the fact that current
computers are 10x too slow for real time decoding.

Has anyone tried SDTV decoding. Is it quicker? Or does the multichannel
information need to be decoded whether you need it or not?
