Are there any lossless video formats in common use? One is unlikely to be introduced if not, so you might need a lot more than one pixel/bit. But at the same time, you don't need to limit to black-and-white. Even just black/white/red/green/blue/purple/yellow/turquoise would be four times as much bandwidth, and I would be very surprised if even lossy video couldn't reliably distingish up to 64 colours. I don't think many people currently have 22.5M/s download speeds anyway, so it's probably not a big deal.
