Inter-layer reference picture restriction for high level syntax-only scalable video coding
In one implementation, an apparatus is provided for encoding or decoding video information. The apparatus comprises a memory unit configured to store reference layer pictures associated with a reference layer, an enhancement layer, or both. The apparatus further comprises a processor operationally coupled to the memory unit. In one embodiment, the processor is configured to restrict usage of at most one reference layer pictures that has a different spatial resolution than a current picture as an inter-layer reference picture, and predict the current picture using inter-layer prediction and the inter-layer reference picture.
