DEVICES AND METHODS FOR PROCESSING VIDEO DATA WITH SIGNALING OF OPERATION POINTS FOR THE HIGH EFFICIENCY VIDEO CODING (HEVC) STANDARD

摘要

A first descriptor describes an operation point. The second descriptor is a hierarchy descriptor or a hierarchy extension descriptor. The second descriptor has a hierarchy layer index value equal to a value of the second syntax element. A first value of a first syntax element in the first descriptor specifies that an elementary stream indicated by a second syntax element in the first descriptor, when not present in an elementary stream list, shall be added into the list, and an elementary stream indicated by an index in the second descriptor, when not present in the list, shall be added to the list. Responsive to determining the first syntax element has a second value different from the first value, adding the elementary stream indicated by the second syntax element, when not present in the list, into the list, but not the elementary stream indicated by the index in the second descriptor.
