Abstract (en)
[origin: WO2021068738A1] The present invention provides a method of joint signaling of high-level syntax (HLS) weighted prediction parameters and the reference picture list, wherein the reference picture list comprises reference pictures having the same picture order count (POC) parameter, the method comprises: determining syntax elements to be signaled, wherein the syntax elements include a reference picture list and at least one HLS weighted prediction parameters; and signaling the determined syntax elements in a coding order with a restriction on the binarization of the syntax element that have a later position in the coding order.
