ABSTRACT:
A scan path is generated using one or more two-dimensional sets of training signals. For encoding, a two-dimensional set of signals is encoded using the scan path. For decoding, a two-dimensional set of encoded signals is decoded using the scan path. In a preferred embodiment, a plurality of different scan paths are generated for a plurality of quantization levels; signals are transformed and quantized using selected quantization levels; and the quantized, transformed signals are encoded using the scan paths corresponding to the selected quantization levels.
