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.
Claims30
A method of decoding multi-layer video data, the method comprising:
- receiving 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;
- in response to the value for the first syntax element indicating that the dependency type syntax element is not signaled:
- determining that the type of dependency of the current layer relative to the reference layer is a predetermined type;
- and
- decoding a block of the current layer using inter-layer prediction conforming to the predetermined type.
A method of encoding multi-layer video data, the method comprising:
- for coded video data comprising multiple layers, determining whether to encode the multiple layers using a same dependency type for all layers of the multiples layers or multiple dependency types, wherein a dependency type identifies a type of dependency of a current layer relative to a reference layer;
- and
- based on determining whether to encode the multiple layers using the same dependency type or multiple dependency types, determining a value for a first syntax element representing whether a dependency type syntax element for a current layer is signaled.
An apparatus that performs video coding, the apparatus comprising:
- a memory storing video data;
- and
- a video coder comprising one or more processors configured to:
- receive 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;
- in response to the value for the first syntax element indicating that the dependency type syntax element is not signaled:
- determine that the type of dependency of the current layer relative to the reference layer is a predetermined type;
- and
- decode a block of the current layer using inter-layer prediction conforming to the predetermined type.
A computer-readable storage medium storing instructions that when executed by one or more processors cause the one or more processors to:
- receive 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;
- in response to the value for the first syntax element indicating that the dependency type syntax element is not signaled:
- determine that the type of dependency of the current layer relative to the reference layer is a predetermined type;
- and
- decode a block of the current layer using inter-layer prediction conforming to the predetermined type.
