Abstract:
The invention relates to a motion compensation performed under an inter-frame prediction. A fractional sample interpolation is applied on retrieved samples to generate fractional samples. The fractional sample interpolation comprises a plurality of filtering operations, and all of filtered results from the filtering operations are truncated down to a predetermined bit depth independent of the bit depth of the samples stored in the reference picture memory.

Claim (Index 7):
A video decoding device for motion compensation performed under an inter-frame prediction, the device comprising:\n a retrieving section retrieving samples from a reference picture memory; a first fractional sample interpolation applying section applying a first fractional sample interpolation on the samples retrieved from the reference picture memory in a first direction, to generate a first set of fractional samples; and a second fractional sample interpolation applying section applying a second fractional sample interpolation on the first set of fractional samples, in a second direction to generate a second set of fractional samples, wherein the samples are represented with a first bit depth and the first set of fractional samples is represented with a second bit depth that is constant regardless of the first bit depth of the samples, wherein quarter-pel samples are generated by applying an 8-tap FIR filter having at least [\u22121, 4, \u221211, 40, 40, \u221211, 4, \u22121] as the first fractional sample interpolation and the second fractional sample interpolation.
