On decoding MPEG-4 reversible variable length codes
Recently, Webb presented some efficient indexing methods for decoding reversible variable length codes (RVLCs) which are used to encode MPEG-4 DCT coefficients. Given an RVLC, this paper presents two new indexing methods for decoding the RVLCs of MPEG-4 DCT coefficients. Compromising the time requirement, our proposed decoding methods need the least row memory requirement when compared to Webb's methods.
