Patent ID: 8582639

Claim:
A method for encoding of a sequence of data points using a lossy data compression process implemented by a processor, the method comprising: assigning, with the processor, a quantization index u to each data point based on quantizing that data point using a quantizer for each quantization index u of at least some of the quantization indices, calculating, with the processor, an adaptive reconstruction level q u for that quantization index u that minimizes the joint cost of total distortion from quantization of the data points to that quantization index u and the rate of transmitting the adaptive reconstruction level q u , wherein the adaptive reconstruction level is based upon the actual data points quantized to that quantization index u; encoding, using the processor, the adaptive reconstruction levels q u ; and encoding, using the processor, for each data point, its respective assigned quantization index u, wherein the sequence of data points comprise one of audio data, image data, and video data.
