An improved Context-based Adaptive Binary Arithmetic Coding (CABAC) is proposed for applications in video compression. The improved CABAC is characterized by higher coding efficiency as compared to that of the original CABAC as standardized in ISO MPEG-4 AVC (Advanced Video Coding) and ITU-T H.264. In the proposal, the increase of compression ratio is obtained by application of more exact data statistics estimation based on well-known data modeling algorithm: Context-Tree Weighting (CTW).
