The subband scheme is one of the most promissing schemes for super HDTV coding. In this paper, we propose two types of multidimensional multichannel subband scheme. Using the concept of the complementary subsampling, the properties of the analysis and synthesis filters axe analyzed. Coding gain is calculated for the proposed scheme by using a picture model. The proposed scheme shows coding gain higher than the conventional scheme.
