    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: An improved system and method for implementing efficient decoding of scalable video bitstreams is provided. A virtual decoded picture buffer is provided for each lower layer of the scalable video bitstream. The virtual decoded picture buffer stores decoded lower layer pictures for reference. The decoded lower layer pictures used for reference are compiled to create a reference picture list for each layer. The reference picture list generated by the virtual decoded picture buffer is used during a direct prediction process instead of a target reference list to correctly decode a current macroblock.

    摘要: A system and method for implementing low complexity multi-view video coding. According to various embodiments, single-loop decoding is applied to multi-view video coding. For N coded views, where only M of the N views are to be displayed, only those M views are required to be fully decoded and stored to a decoded picture buffer (DPB) when needed. Pictures of other views are only partially decoded or simply parsed and do not have to be stored into the DPB. Various embodiments also provide for an encoder that encodes multi-view video bitstreams in accordance with the single-loop decoding concept, as well as a decoder that utilizes single-loop decoding to decode and output on a subset of the encoded views from a multi-view bitstream.
