Latency and bandwidth.
We push about 3.4 GByte/s (or 27.5Gbit/s) to our displays. Even a 26Gbit/s DP1.4a HBR3 link needs display stream compression for that. So a wireless link will absolutely need strong compression.
H.265 can push that to maybe (ballpark) 200Mbit/s, which is fairly feasible. But that will need to be evaluated and optimized for text quality and latency. Some googling suggests 100ms end-to-end latency as good. That's pretty high for VR, IMO.
[Edit: fixed the DP1.4a bandwidth)
- akvadrako 5y agoYou can definitionally get lower latency with H.264 - somewhere around 5-10ms encode and 2ms decode. That's what makes Parsec and streaming gaming platforms possible even with all the other latencies involved. H.265 might be slower, but EVC, especially LCEVC, is supposed to be about 30% lower latency encoding than H.264.
- kanetw 5y agoInteresting. I wonder why the googled numbers were so high then. I'll take a look sometimes; wireless streaming would be cool.
