摘要: Techniques are described related to deriving a reference picture set. A reference picture set may identify reference pictures that can potentially be used to inter-predict a current picture and picture following the current picture in decoding order. In some examples, deriving the reference picture set may include constructing a plurality of reference picture subsets that together form the reference picture set.

摘要: Techniques are described related to constructing reference picture lists. The reference picture lists may be constructed from reference picture subsets of a reference picture set. In some examples, the techniques may repeatedly list reference pictures identified in the reference picture subsets until the number of entries in the reference picture list is equal to the maximum number of allowable entries in the reference picture list.

摘要: In one example, a device for coding video data includes a video coder configured to code, for a bitstream, information representative of which of a plurality of video coding dimensions are enabled for the bitstream, and code values for each of the enabled video coding dimensions, without coding values for the video coding dimensions that are not enabled, in a network abstraction layer (NAL) unit header of a NAL unit comprising video data coded according to the values for each of the enabled video coding dimensions. In this manner, NAL unit headers may have variable lengths, while still providing information for scalable dimensions to which the NAL units correspond.

摘要: In one example, a video coder is configured to code information indicative of whether view synthesis prediction is enabled for video data. When the information indicates that view synthesis prediction is enabled for the video data, the video coder may generate a view synthesis picture using the video data and code at least a portion of a current picture relative to the view synthesis picture. The at least portion of the current picture may comprise, for example, a block (e.g., a PU, a CU, a macroblock, or a partition of a macroblock), a slice, a tile, a wavefront, or the entirety of the current picture. On the other hand, when the information indicates that view synthesis prediction is not enabled for the video data, the video coder may code the current picture using at least one of intra-prediction, temporal inter-prediction, and inter-view prediction without reference to any view synthesis pictures.

摘要: Techniques are described related to coding of long-term reference pictures for a reference picture set. In some examples, a video coder may code candidate long-term reference pictures in a parameter set. The video coder also code syntax elements that indicate which long-term reference pictures from the candidate long-term reference pictures belong in the reference picture set.
