In general: Top part handles the brightness (Y) and the bottom part handles the color (UV). The part to the right combines both again.
The result looks something like this:
Color is still to be fixed.
The command line generating this:
$ ffmpeg -i /home/marble/lib/Videos/bigbuckbunny.mp4 -codec:v rawvideo -vf 'scale=702:576:force_original_aspect_ratio=decrease,pad=702:576:(ow-iw)/2:(oh-ih)/2' -f rawvideo -pix_fmt yuv444p -r 50 - | ~/curr/Software\ Proejcts/video2pal/grc/pal_transmit.py
