Evaluation of Deblocking Filter for H.263 Video Codec & Proposed Algorithm for Entropy Coding for MPEG-4 Video Codec

In this Paper Performance of H.263 Video Codec is evaluated for Deblocking Filter for various Video sequences. Also Algorithm for MPEG-4/AVC for Deblocking Filter and Entropy Coding Scheme is proposed. These advanced options are evaluated and analyzed in terms of output parameter, which is Peak Signal to Noise ratio (PSNR) or Quality of Picture. The improvement in video quality with the use of this advance option Deblocking Filter of H.263 is of the order of 0.8 dB or more. Along with Proposal of Algorithm for Deblocking Filter and Entropy Coding Scheme Effect of Deblocking Filter on the Quality of Picture for MPEG-4/AVC is also shown. MPEG-4 is an ISO/IEC video coding standard which supports highly collaborative multimedia applications along with many traditional applications. It includes many advanced functionalities such as Error resilience & concealment, scalabilities and many more. Algorithm for Context Adaptive Binary Arithmetic coding (CABAC) for MPEG-4 Video Codec is proposed. The compression efficiency of CABAC is 10-15% better as compared to CAVLC and it can be up to 32% better when compared to other entropy compression methods such as Huffman.
