Title:
Instructions for inter-layer picture type alignment in multi-layer video coding
Document Type and Number:
Japanese Patent JP6363172
Kind Code:
B2
Abstract:
In one example, the disclosure is directed to techniques that include receiving a bitstream comprising at least a syntax element, a first network abstraction layer unit type, and a coded access unit comprising a plurality of pictures. The techniques further include determining a value of the syntax element which indicates whether the access unit was coded using cross-layer alignment. The techniques further include determining the first network abstraction layer unit type for a picture in the access unit and determining whether the first network abstraction layer unit type equals a value in a range of type values. The techniques further include setting a network abstraction layer unit type for all other pictures in the coded access unit to equal the value of the first network abstraction layer unit type if the first network abstraction layer unit type is equal to a value in the range of type values.
