Abstract:
1. A method for decoding video data, the method comprising: modifying a first weight parameter to conform to a bit configuration of universal weight prediction factors; modifying a second weight parameter to conform to the bit configuration, wherein the modification of the first weight parameter and the modification of the second weight parameter are dependent on a form of weighted prediction used to encode the video data; and using a formula to determine a sample of a combined weighted prediction, wherein parameters of the formula include a sample from a prediction block of a first reference picture, the modified first weight parameter, a sample from a prediction block of a second reference picture, and the modified second weight parameter, wherein the formula is used in processing of compressed video data in any of a plurality of encoding standards, wherein each respective encoding standard from the plurality of encoding standards implements a different form of weighted prediction.
