Abstract:
There is disclosed apparatuses, methods and computer programs for utilizing motion prediction in video coding. A block of pixels of a video representation encoded in a bitstream is read, and a type of the block is determined. If the determining indicates that the block is a block predicted by using two or more reference blocks, a first reference pixel location in a first reference block is determined and a second reference pixel location in a second reference block is determined. The first reference pixel location is used to obtain a first prediction. Said first prediction has a second precision, which is higher than the first precision. The second reference pixel location is used to obtain a second prediction, which also has the second precision. The first prediction and the second prediction are combined to obtain a combined prediction; and the precision of the combined prediction is reduced to the first precision.

Claim (Index 1):
A method for decoding or encoding video, the method comprising:\n determining a coding type of a block of pixels of the video, values of said pixels having a first precision, wherein the first precision indicates the number of bits needed to represent values of said pixels; determining a first reference pixel location in a first reference block and a second reference pixel location in a second reference block; using said first reference pixel location to obtain a first prediction, said first prediction having a second precision, which is higher than said first precision; using said second reference pixel location to obtain a second prediction, said second prediction having the second precision, which is higher than said first precision, wherein the second precision indicates the number of bits needed to represent values of said first prediction and values of said second prediction; obtaining a combined prediction based at least partly upon said first prediction and said second prediction; and decreasing a precision of said combined prediction by shifting bits of the combined prediction to the right.
