Abstract :
Proposed are various codec architectures for encoding the quantisation error of MPEG-2 base layer transcoders using embedded bitstreams technologies. An existing solution based on fine granular scalability is reviewed and amended resulting in drift-free picture decoding. Likewise, two new approaches to MPEG-2 SNR scalability based on JPEG2000 (J2k) coding technology are proposed. It is shown that no modifications are required for MPEG-2-compliant single-layer decoders whilst replacing the static (not adaptable) MPEG-2 SNR video layers with embedded bitstreams.
