Analysis of video coding standards using PSNR and bit rate saving

This paper mainly deals with the performance comparison of several video coding standards by means of peak signal-to-noise ratio and subjective testing like Rate Distortion (RD) curves and average bit-rate savings. A particular procedure is applied for the video coding standards H.265/High Efficiency Video Coding (HEVC), H.264/MPEG4- Advance Video Coding (AVC), MPEG4V2, MPEG4 and the Google video codec's such as VP8, VP9 at different bit-rates and Peak Signal-to-Noise Ratios (PSNR) are estimated. The bit-rate reduction on an average is achieved about 50% for comparable to earlier video coding standards. The results obtained illustrate the H.265/HEVC achieving high peak signal-to-noise at low bit rates. This resembles high coding efficiency, comparing with lower versions of video coding standards.
