Detailed Overview of HEVC/H.265

Currently a real HEVC/H.265 usually outperforms AVC/H.264 above 30% at bit rate.

Shevach Riabtsev provided a great presentation about HEVC/H.265 in

In his presentation, he described HEVC/H.265 as follows

Shevach said "In addition to AVC/H.264, SAO and SAO Params Estimation added. 

SAO Params Est. can be executed right after deblocking or right after the reconstruction 

as shown in the figure.

HEVC similarity with AVC/H.264 allows quick upgrading of existing AVC/H.264 solutions

to HEVC ones."
