MPEG-H part 2


(n.) Refers to the High Efficiency Video Coding (HVEC) compression standard MPEG-H part 2. It is an improved version of H.264, Advanced Video Coding (AVC), and provides up to 50% higher compression with similar video quality at the same bit rate. The primary advantage of H.265 is that it transforms variable larger block sizes between 4×4 and 32×32, which are called Coding Tree Units. The required bandwidth for a 4K video delivered over H.265 is 15 megabits per second (mbps), while the same 4K content requires 32 mbps using H.264. At the time of this writing, HEVC was used by nearly half of the of video developers worldwide, gaining ground on the more widely implemented H.264 AVC format.
