Abstract: Context Adaptive Binary Arithmetic Coding (CABAC) is a technique for entropy coding initially presented in H.264/AVC what’s more, now utilized as a part of the most up to date standard High Efficiency Video Coding (HEVC). While it gives high coding productivity, the information conditions in H.264/AVC CABAC make it trying to parallelize and along these lines, restrict its throughput. As needs be, amid the standardization of entropy coding for HEVC, both coding performance and throughput were considered. This paper highlights the key strategies that were utilized to empower HEVC to conceivably accomplish higher throughput while conveying coding increases relative to H.264/AVC. The proposed enhancements including prenormalization, hybrid way coverage and, lookahead rLPS to diminish the basic way deferral of double Binary Arithmetic Coding (BAE) by abusing the inadequacy of information conditions in rLPS refreshing. The context modeling and binarization segments are likewise upgraded. Therefore, CABAC encoder conveys a normal of 4.37 bins per clock cycle
