Abstract:

In general, techniques are described for encoding parameters with unit sum. In one example, an apparatus comprising a control unit implements these parameter encoding techniques. The control unit determines parameters that sum to a constant or unit sum. The control unit includes a parameter coding unit that segments a space that contains the plurality of parameters into a set of portions. The parameter coding unit assigns a different one of a plurality of codewords to each of the portions, selects one of the set of portions that contains a point defined by the plurality of parameters, and codes the plurality of parameters using one of the plurality of codewords assigned to the selected one of the plurality of portions. Rather than code only a subset of these parameters, the parameter coding unit codes all of the parameters with the result of potentially reducing quantization error.
