This Paper deals with the Evaluation, Analysis and Algorithm of Context Adaptive Binary Arithmetic coding (CABAC) MPEG-4 Video Codec.MPEG-4 is an ISO/IEC video coding standard which supports highly interactive multimedia applications as well as traditional applications.It includes many advanced functionalities such as interactivities, scalabilities and error resilience.The growing popularity of MPEG-4 in the field of animation and interactive movies was the main motivation to include it in this work.This paper investigates the effect of CABAC Entropy coding scheme that is a crucial parameter for the performance of MPEG-4 video coder.In this paper Algorithm for Context Adaptive Binary Arithmetic coding (CABAC) is proposed for MPEG-4 Video Codec.The compression efficiency of CABAC is 8-12% better as compared to CAVLC and it can be up to 30% better when compared to other entropy compression methods.
