Abstract: The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.

Abstract: 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 video coder may also add the at least one filtered layer component to a reference picture set for performing inter-layer prediction of a layer other than the first layer of video data.
