Patent ID: 7389005

Claim:
A method for processing digital data that incorporate video and/or audio information, wherein the digital data include a first sequence of digital data values which incorporate video and/or audio information for a sequence of areas, wherein for each area A in the sequence of areas, a corresponding digital data value S A in the first sequence incorporates video and/or audio information for the area A, wherein the areas A are areas in a space of one or more dimensions, each dimension representative of a physical position or time; wherein the first sequence includes consecutive digital data values S A1 , S A2 , S A3 , S A4 corresponding to areas A1, A2, A3, A4, and the method comprises performing, by a circuit, a data processing operation that incorporates interpolation of the digital data for an area B, wherein an interpolated value of the data for the area B according to the said interpolation is: P A3 =K 1 S A2 +K 2 S A4 wherein K 1 and K 2 are functions of parameters L and R, where: L is indicative of an absolute value |S A1 −S A2 | and/or an absolute value of a rate of change of the first sequence from S A1 to S A2 with respect to at least physical position or time; C is indicative of an absolute value |S A2 −S A3 | and/or an absolute value of a rate of change of the first sequence from S A2 to S A3 with respect to at least physical position or time; R is indicative of an absolute value |S A3 −S A4 | and/or an absolute value of a rate of change of the first sequence from S A3 to S A4 with respect to at least physical position or time; if L<R , then K 1 >K 2 ; and if R<L , then K 2 >K 1 .
