Broadcast analog NTSC requires about 6MHz of bandwidth and I believe VHS pushed that down to more like 3MHz without many people noticing. That's trivial compared to trying to get a digital 3Gbps signal around the house wirelessly.
Edit: I didn't realise that it was sending a digital signal, but, yeah, MPEG-2 can easily give 20:1 compression and still produce a decent picture
