Reference picture lists modification

摘要

Systems, methods, and instrumentalities are disclosed relating to modifications to reference picture lists used for multiple layer video coding. A bitstream that may include a reference picture list of a slice may be received. An indication to reposition a reference picture within the reference picture list from a first position to a second position may be received. An indication to insert a reference picture within the reference picture list at a position may be received. The reference picture may be repositioned and/or inserted in the reference picture list in response to receiving the indication. A reference picture previously associated with the position may be shifted in the reference picture list according to the indication to reposition and/or insert the reference picture, although an indication to reposition the reference picture previously associated with the position may not be received. The slice may be decoded using the reference picture list.

主权项

1. A method comprising:
receiving a video signal; determining encoding statistics related to the video signal during a first encoding pass using one or more reference picture lists; reordering, prior to a second encoding pass, pictures in the one or more reference picture lists based on the encoding statistics determined from the first encoding pass, wherein the encoding statistics comprise motion-compensated distortion information such that the pictures with smaller motion-compensated distortion are assigned lower indices in the one or more reference picture lists; and encoding the video signal during the second encoding pass using the one or more reordered reference picture lists.
