Reversible variable length coding (RVLC) is an important robust entropy coding
technique for error resilient video transmission. The popular DCT-based video codecs all
can use it. RVLC supports both...

Context-Based 2D-VLC Entropy Coder in AVS Video Coding Standard.
It is well observed that usually the run-length of successive zero coefficients becomes longer and the magnitude of non-zero coefficients gets smaller while the DCT subband frequency increases. So the...
