Abstract: A video decoder receives a value for a first syntax element representing whether a dependency type syntax element for a current layer is signaled, wherein the dependency type syntax element identifies a type of dependency of a current layer relative to a reference layer; and in response to the value for the first syntax element indicating that the dependency type syntax element is not signaled determines that the type of dependency of the current layer relative to the reference layer is a predetermined type and decodes a block of the current layer using inter-layer prediction conforming to the predetermined type.

Abstract: Systems, methods, and devices for coding multilayer video data are disclosed that may include encoding, decoding, transmitting, or receiving a non-entropy encoded layer dependency information at a position within a video parameter set (VPS) extension prior to syntax elements of the VPS extension that are entropy encoded. The systems, methods, and devices may encode or decode the non-entropy encoded layer dependency information before an entropy encoded syntax element. The systems, methods, and devices may encode or decode video data of one or more of the layers of video data based on the non-entropy encoded layer dependency information. The layer dependency information indicates whether one of the layers is a direct reference layer for another of the layers.
