Performance analysis and evaluation of proposed algorithm for advance options of H.263 and H.264 video codec

Abstract

This paper deals with the evaluation, analysis and algorithm of advance options of H.263 and H.264/AVC video codec. Analysis and evaluation of H.263 video codec is important because it enable us to determine output parameter, which is peak signal to noise ratio (PSNR) or quality of picture. In this paper, the performance of H.263 video codec is evaluated and analyzed for various advance options such as syntax based arithmetic coding (SBAC), advanced prediction mode, unrestricted motion vector mode etc. The H.264/AVC is an international video coding standard, jointly developed by groups from ISO/IEC and ITU-T, which aims at achieving improved compression performance. Various applications of H.264/AVC include conversational, storage, and streaming. For H.264 Video codec we proposed algorithm for advance options such as context adaptive binary arithmetic coding (CABAC). The improvement in video quality with the use of these advance options of H.263 is of the order of 0.8 dB or more. The compression efficiency of CABAC is 10-15% better as compared to context adaptive variable length coding (CAVLC) and it can be up to 32% better when compared to other entropy compression methods such as Huffman Coding.
