You'd need 3Gbps to push uncompressed 1080p data. If you look at USB 3.0 and make a not-unreasonable bet that Lightning is slower, then you simply don't have the bandwidth to do so.
- StringyBob 14y agoAs well as bandwidth, power consumption. Chucking 3Gbps down a long wire is going to reduce battery life for a mobile product. Perhaps the controller can support it, but heat dissipation in the phone is significant?
- morsch 14y agoI can't imagine that compressing and decompressing MPEG 4 uses less power, given specialised hardware for each task.
- makomk 14y agoActually, that doesn't make sense - the adapter is powered from the iPhone or iPad and still has to chuck 3 Gbps down a long wire, except now you're using the iPhone's h.264 encode hardware and an entire ARM SoC in the adapter which you have to power too.
