I think we can record or view HDTV streams on computer via ethernet connection.
Simply sending digital MPEG4 stream to computer via PIPE -> Ethernet Socket. I think implementation is easy too.
It's not good for record videos while watching TV, but it's worth for record our favorite programs.
Process could be automatized too.
I think we needed to understand TV@s algorithm first.
