Is it perhaps possible to implement some of the decoding in the USRP, so as not to clog the PC's CPU?

Hmm. I'm not sure I see this. If the luminance channel and the color channel are being digitized through different channels but with extremely exact timing, can't the phase be kept synchronized for at least a full line? The synchronization code should make sure that they're resynced at the beginning of each line. Or is there simply not enough exactness in the timing. -- Nathanael Nerode <[EMAIL PROTECTED]> Bush admitted to violating FISA and said he was proud of it.
