You could fit many QR codes on screen at a time.
Or, better yet, you could just send raw pixels as bits, white = 0, black = 1. With 1024x768 HD video, that's a possible 768K/Frame => 22.5M/s @ 30 FPS!

What do you think? A friend who's exceptional at maths (I'm not) told me it's not possible, however I don't like when naysayers come and tell it's impossible. Still it demotivated me. Do you think it's possible?
Explained in two words: "Optical Transmission"
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.
