摘要：

We compare the subband compression capabilities of eight filter sets (consisting of linear phase quadrature mirror filters (QMF's) perfect reconstruction filters, and nonlinear phase wavelets) at different bit rates, using a filter-based bit allocation procedure developed in this paper. Using DPCM and PCM in HDTV subband coding, we have found that QMF's have an edge over the rest.
