Patent ID: 7702709

Claim:
In a computing device, a method for configuring a decoder, the method comprising: performing, by a computing device, at least the steps of: splitting a sample space of input values into sub-regions comprising a first sub-region and a second sub-region; associating a first polynomial function with the first sub-region and a second polynomial function with the second sub-region, wherein the first sub-region and the second sub-region are of unequal size; determining coefficients of the first polynomial function that minimize an approximation error function comprising the first polynomial function and a particular decoding expression over input values of the first sub-region; determining coefficients of the second polynomial function that minimize an approximation error function comprising the second polynomial function and the particular decoding expression over input values of the second sub-region; and configuring a decoder by, at least in part, storing the coefficients in a memory associated with the decoder; wherein the stored coefficients are utilized by the decoder during operation of the decoder to decode audio and/or video information while the computing device and the decoder have been communicatively decoupled.
