We propose a spatio-amplitude scalable extension to the MPEG-2 algorithm for coding 10-bit video. The proposed scalable scheme utilizes the existing MPEG-2 tools and VLC tables. It has a base and an enhancement layer, where both layers employ 8-bit DCT/IDCT. In the proposed scheme, an 8-bit version of a given 10-bit video is coded in the base layer; the difference between the given 10-bit video and its prediction formed from the decoded 8-bit base layer data (and optionally from the decoded 10-bit data) is coded in the enhancement layer. Our results show that if a given bitrate is properly allocated between the base and enhancement layers, the 10-bit amplitude scalable scheme can significantly outperform the usual 8-bit scheme operated at the given bitrate.
