摘要
A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.

The above approaches, through various restrictions of inter-layer prediction, may be referred to as layer-level two-loop approaches. In one embodiment, a bitstream, which may contain multiple layers, is restricted such that motion compensation is used to decode decoding at most two layers.
