But there's a problem.  This connects to the output of existing devices, 
so it's going to be progressive 50/60fps or higher.  Furthermore, 
they're using jpeg, so each frame is encoded individually.  A 1080p60 
stream at 60mbps (125KB/frame) is well past the point where jpeg starts 
visibly artifacting.
