how to do this & what hardware do you need

Some info on PDTV:
Basically we capture the mpeg stream as it comes from the
satellite. There is no analog processing at any time, thus the file that tmgenc is fed with, is digital broadcast quality, where there is zero loss. Whatmore is that the
file fed has a dvd-like bitrate (4000-6000). Now you
probably have an idea of why we've decided to call it PURE
