New CAVLC design for lossless intra coding
The context-based adaptive variable length coder (CAVLC) in H.264/AVC is not appropriate for lossless video coding because it was designed for lossy video coding. Since statistical characteristics of residual data in lossy and lossless coding are quite different, we design a new VLC table for the number of non-zero coefficients and an adaptive scheme for VLC table selection in level coding for lossless intra coding. Experimental results show that the proposed CAVLC scheme provides approximately 10% bit saving, compared to the original CAVLC scheme in H.264/AVC.
