Abstract
Context-based Adaptive Binary Arithmetic Coding (CABAC) is a method of entropy coding which is widely used in the next generation standard of video coding called High Efficient Video Coding (HEVC). It processes the amount of transform coefficients. Due to the complexity of CABAC, it accounts for the significant portion of the whole coding efficiency. Based on the feature of CABAC and transform coefficients, a fast CABAC algorithm is proposed in this paper by reducing the number of bins to be processed. Experiment results show that the proposed method achieves about 5.99% times saving in average of QP=17 with little performance degradation compared with the CABAC algorithm in test model HM-6.0.
