Abstract
This paper proposes an interworking between MPEG-2 Intraframe coding and JPEG2000 international standards. The latter codec is integrated into the base layer of spatial scalability encoders whilst retaining full compatibility with MPEG-2 decoders. The proposed solution combines existing ISO/IEC MPEG standards and is elaborated upon with respect to three application areas; bitstream format portability and adaptability, bitstream switching and combined video scalability. The paper elaborates upon the proposed coding architectures and compatibility with published MPEG standards. The proposed coding architecture is compared against counterpart video transcoders, scalable and single layer codecs. It is shown that the proposed spatial encoder is superior to all the aforementioned codecs whilst enjoying an extensible architecture capable of serving restricted end systems and hosting additional scalable layers such as SNR and temporal scalabilities.
