Avoidance of Redundant Signaling in Multi-Layer Video Bitstreams
This abstract first appeared for US patent application 20240430485 titled 'Avoidance of Redundant Signaling in Multi-Layer Video Bitstreams
Original Abstract Submitted
a method of decoding includes receiving a bitstream having a plurality of layers and a video parameter set (vps), where the vps includes a direct reference layer flag, where the direct reference layer flag equal to a first value specifies that a second layer is not a direct reference layer for a first layer, and where the direct reference layer flag equal to a second value specifies that the second layer is the direct reference layer for the first layer; deriving a reference layer flag by: initially setting the reference layer flag to the first value; and updating the reference layer flag to the second value when the direct reference layer flag has the second value; and decoding a picture from the first layer in accordance with the reference layer flag to obtain a decoded picture.
