You're making great progress! Any idea what's wrong with the 2.0 bit timing? Once you get that done we can work on some serious optimization, since the chain as constituted has a lot of redundancy. Matt On Mon, 2006-05-08 at 14:57 -0400, Charles Swiger wrote: > It turns out to be not too awefu

It turns out to be not too awefully difficult (tho not officially approved ;) to modify the gnuradio-0.9 atsc code to use a subset of blocks, specifically everything from bit-timing-loop to field-sync-demux (float in, soft-data-segments out). So here's what I have working across 4 cpu's: Start
