| 摘要 |
The invention relates to encoding and decoding pixel blocks of a video frame through a hybrid mode involving usage of a first prediction of a pixel block and at least a second prediction of the pixel block. An initial first weighting factor is modified using a factor modifier to generate a first weighting factor comprising multiple different factor values that are assignable to the different pixel-based first prediction values of the first prediction. The first weighting factor is applied to the first prediction and a second weighting factor is applied to the second block prediction. The at least two weighted predictions are then combined to form a hybrid prediction of the current pixel block.
