Broadcast quality is a relative term -it might be distributed at MPEG2 / 20 mbits per second but it is edited at Uncompressed 137 MB per/sec!!!
(10 bit @ 1920 x 1080 @ 29.97fps = 136.72 MB per/sec, or 492 GB per/hr)....and thats at a sampling rate of 4:2:2. So if you were doing 35mm film transfers to HD NTSC you would want to use the full sampling rate of 4:4:4 i.e. 2x the data rate = 274 MB per/sec
I'm currently building a HD editing suite and am investigating if 802.3ad Aggregated Gigabit will sustain my required datarates of 120 & 240 MB per/sec.
As I'm on mixed platforms inc. OSX, the only product I have found is Small-Tree drivers.
Have these sort of data rates been achieved over copper on Linux / Win yet?
