The Panasonic TYFB7SD SDi board is a pretty expensive board for the Panasonic palsmas. I can't find anywhere that says what it actually does! The best I can find is a photo showing just two BNCs. Not even the Panny web site or Google will give it up on a search. It's obviously not the same as a composite (PAL/NTSC) input board (which is MUCH cheaper). Someone round here must know!
