Weighted prediction parameter signaling for video coding

A method of weighted prediction (WP) signaling, the method comprising:

• receiving a first plurality of WP parameters, wherein each of the first plurality of WP parameters is associated with an entry of a first reference picture list;
• receiving a flag;
• determining a value of the flag;
• and
• on a condition that the value of the flag is a first value and a second reference picture list is identical to the first reference picture list, setting a second plurality of WP parameters associated with respective entries of the second reference picture list by copying the WP parameters from corresponding entries of the first reference picture list.

A method of weighted prediction (WP) signaling, the method comprising:

• receiving a first plurality of WP parameters in a video bitstream, wherein each of the first plurality of WP parameters is associated with an entry of a first reference picture list;
• receiving a flag;
• determining a value of the flag;
• and
• on a condition that the value of the flag is a first value, setting a second plurality of WP parameters associated with entries of a second reference picture list by reusing the WP parameters associated with the entries of the first reference picture list that are relevant to the second reference picture list.

A video coding device comprising:

• a processor configured to at least:
• receive a first plurality of WP parameters, wherein each of the first plurality of WP parameters is associated with an entry of a first reference picture list;
• receive a flag;
• determine a value of the flag;
• and
• on a condition that the value of the flag is a first value and a second reference picture list is identical to the first reference picture list, set a second plurality of WP parameters associated with entries of the second reference picture list by copying the WP parameters from corresponding entries of the first reference picture list.
