ABSTRACT:
Two or more run-val mapping tables are selected to encode different subsets of video signals of a sequence of video signals. Each run-val mapping table is selected to map a particular set of run-val pairs to a corresponding set of run-val codes. Each run-val pair comprises a run and a val, the run corresponding to a length of a run of video signals having value zero and the val corresponding to a video signal having a non-zero value. Each run-val mapping table is used to generate a different part of an encoded bitstream for the sequence of video signals. The encoded bitstream is then decoded using the two or more selected run-val mapping tables. In a preferred embodiment, the selected run-val mapping tables are explicitly identified in the bitstream.
