I think we discuss it partially @ http://forum.doom9.org/showthread.php?t=165596&page=2

Although it is good we have a separate thread for it.

Some news site state a total of 500 patents designed for HEVC. I always wondered how much more expensive it is to buy out all the HEVC patents then 160 million for vp8.

Someone state HEVC is not H.265, while Wiki refers to both. Which is correct?

I was reading CABAC for HEVC is actually computationally less expensive then H.264 CABAC. What could theoretically means main profile to be better suited for mobile usage? Although i am not sure if the efficiency is worth the implementation effort on both hardware and software. As most of today Mobile H.264 usage are still stuck at wither Baseline ( o.O ) or Mainline profile.

Then we need x264 devs or some other teams to develop a decent encoder for it. Since x264 codebase could be adopted for x263 and xvp8 i wonder if xhevc is theoretically possible.
