HEVC , H265 Technical Overview

January 25, 2013, the ITU announced the completion of the first stage approval of the H.265 video codec standard and in the last 1 year several vendors/entities have started to work on the first implementations of H.265 encoders and decoders. Theoretically HEVC is said to be from 30 to 50% more efficient than H.264 (especially at higher resolutions) but is it really that simple ?

HEVC defines a “low delay” configuration capable of low latency operation, it's unclear what will be sacrified.  

 In general, HEVC decoders are expected to have 2-3 times the computational complexity of AVC decoders, and HEVC encoders are expected to have up to 10 times the computational complexity of AVC encoders.
