Study on H.265/HEVC against VP9 and H.264 : On Space and Time Complexity for Codecs

The study analyzes H.265 video compression standard against its predecessor H.264 and Google’s developed VP9. A review of the recent developments in H.265/HEVC standardization have been provided. Analysis takes place using samples of uncompressed videos (frames) subjected to these 3 standards in FFmpeg command line tool with application of different containers. Further, these encoded compressed video samples are the ones which are analyzed on the basis of SCR, SS, bandwidth, size, time, efficiency and practicality. High Efficiency Video Coding (HEVC) is the proposed new generation of video compression standard, which enables substantially higher compression capability than the existing standards and exhibits superior coding performance improvements over its predecessors. Compression performance is owed to quad-tree structure, parallel encoding/decoding (codec), intra-prediction modes, integer transforms etc. With the right codec, multimedia companies could save millions on storage while keeping the quality intact, thereby increasing throughput and profits. Cost efficiency is performed with respect to the business development.
