| Abstract | In this paper, an improvement of coding efficiency of the Context-based Adaptive Binary Arithmetic Coding (CABAC) is proposed for applications in Advanced Video Codecs (H.264/AVC). In the paper, more accurate estimation technique for conditional probabilities of symbols is proposed. To achieve that, the well-known data modeling technique of the Context-Tree Weighting (CTW) is used. A novel method of incorporating CTW into the H.264/AVC codec is proposed. The compression efficiency of the modified H.264/AVC codec (with CTW) has been thoroughly tested and compared against the coding efficiency of the original H.264/AVC (with CABAC). Experimental results show that the use of CTW with CABAC allows for up to 2.5% compression efficiency increase with respect to the original CABAC. |
