METHOD AND APPARATUS FOR MOTION COMPENSATION PREDICTION WITH MULTIPLE FRACTIONAL SAMPLE INTERPOLATIONS

摘要

The invention relates to a motion compensation performed under an inter-frameprediction. A fractional sample interpolation is applied on retrieved samplesto generatefractional samples. The fractional sample interpolation comprises a pluralityof filteringoperations, and all of filtered results from the filtering operations aretruncated down to apredetermined bit depth independent of the bit depth of the samples stored inthe referencepicture memory.
