Comparison between H.264/AVC and JPEG2000 arithmetic encoders

JPEG2000 Part 3 defines the MJ2 file format that should be used to encode video sequences as a succession of independently encoded images. Since MJ2 involves only intra-frame coding, performances of JPEG2000 cannot be easily compared with those of other codecs that exploit both intra and inter-frame coding, e.g the H.264/AVC standard. In this paper we present a hybrid encoder where the JPEG2000 EBCOT algorithm substitutes the standard quantization and arithmetic coding blocks of H.264/AVC. We used it compare the efficiency of the CABAC arithmetic encoder of H.264/AVC with the EBCOT algorithm of JPEG2000. The obtained results can give directions for next generation video coding standards.
