A method and system for coding an image using context-based adaptive VLC where transform coefficients are partitioned into blocks having a block dimension of 4nx4m (with n, m being positive integer equal to or greater than 1). Each block is scanned in a zigzag manner to produce an ordered vector of coefficients having a length of 16nxm. The ordered vector is sub-sampled in an interleaved manner to produce nxm sub-sampled sequences of transform coefficients prior to encoding the transform coefficients using an entropy encoder. |
