JCS_V2_N4_RP3 Video Compression Standards for High Definition Video: A Comparative Study of High Efficiency Video Coding and H.264/MPEG-4 AVC Geethu Raj M. Kannan Journal on Communication Engineering and Systems 2277-5242 2 4 14 19 H.264, MPEG-4 Standards, Video Compression, High Efficiency Video Coding, Advanced Video Coding An increasing number of services and growing popularity of high definition videos are creating much more need for higher coding efficiency. The analysis of design and performance metrics like peak signal-to-noise ratio and subjective quality test evaluate those HEVC encoders can achieve approximately 50% bit rate reduction than H.264/MPEG-4 AVC. The HEVC design is shown to be especially effective for low bit rates, high–resolution video content and low-delay communication applications. This paper also provides an overview and summarizes emerging studies on the coding features of H.262/MPEG-2 video, H.263, MPEG-4 visual. August - October 2013 Copyright © 2013 i-manager publications.
