N2 - We present in this paper a new 3-D subband coding method with low complexity, high performance, and features that facilitate channel error resilience. Four variations of the coder are discussed: one employing an octave band decomposition: on using the discrete cosine transforms (DCT) and two using lapped transforms. The base coder uses generalized adaptive quantization to code the subbands. Good performance at high compression ratios is obtained without traditional motion compensated prediction. Furthermore, these performance improvements can be realized without the use of entropy coding, which can make the system attractive for operation in error prone environments. Experimental results have shown that the subband video coder and its variations are able to achieve significant performance improvement over MPEG-2.
