Abstract
Systems, methods, and instrumentalities are provided to implement weighted prediction (WP) signaling, A decoding device may receive a plurality of first list WP parameters, and a. weights present flag. The weights present flag may indicate whether a plurality of second list WP parameters are signaled. The decoding device may receive the second list WP parameters when the weights present flag indicates that the second list WP parameters are signaled. The plurality of second list WP parameters may be derived when the weights present flag indicates that the second list WP parameters are not signaled. The decoding device may receive a delta parameter present, flag, which may indicate whether a plurality of delta WP parameters are signaled. The decoding device may receive the delta WP parameters, when the delta parameter present flag indicates that the plurality of the delta WP parameters are signaled.
