Abstract
A computer-implemented method and apparatus for encoding a current block of pixels of a current picture of a sequence of pictures, the sequence of pictures comprising a previous picture having a previous reference block and a subsequent picture having a subsequent reference block. A previous residual error is determined between the current block and the previous reference block, and a subsequent residual error is determined between the current block and the previous reference block. At least one interpolated picture interpolated between the previous and subsequent pictures is defined, the interpolated picture having an interpolated reference block. An interpolated residual error is determined between the current block and the at least one interpolated reference block from the previous and subsequent residual errors.
