1. 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.
