Abstract: A video encoder signals, in a bitstream, a syntax element that indicates whether a current video unit is predicted from a VSP picture. The current video unit is a macroblock or a macroblock partition. The video encoder determines, based at least in part on whether the current video unit is predicted from the VSP picture, whether to signal, in the bitstream, motion information for the current video unit. A video decoder decodes the syntax element from the bitstream and determines, based at least in part on the syntax element, whether the bitstream includes the motion information.

Abstract: When coding multiview video data, a video encoder and video decoder may select a candidate picture from one of one or more random access point view component (RAPVC) pictures and one or more pictures having a lowest temporal identification value.

Abstract: Techniques are described for deriving a disparity vector for a current block based on a disparity motion vector of a neighboring block in a 3D-AVC video coding process. The disparity vector derivation allows for texture-first coding where a depth view component of a dependent view is coded subsequent to the coding of the corresponding texture component of the dependent view.

Abstract: A system and method for decoding video. A first syntax element for a block of video data is received, a value of the first syntax element indicating one of a plurality of mapping functions to be used to determine a magnitude of a scaling parameter for cross-component prediction. A second syntax element for the block of video data is received, a value of the second syntax element corresponding to the magnitude of the scaling parameter, wherein receiving the second syntax element includes decoding the value of the second syntax element with a specific binarization method. The magnitude of the scaling parameter is determined using the one of the plurality of mapping functions indicated by the first syntax element and the value of the second syntax element.

Abstract: In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine whether to use color-space conversion for encoding the video data. In response to determining to use color-space conversion, the video coder may quantize data of a first color component of the video data using a first offset of a first quantization parameter (QP) and quantize data of a second color component of the video data using a second offset of a second QP, wherein the second color component is different than the first color component, and the second QP is different than the first QP. The video coder may further inverse quantize data of the first color component using the first offset and inverse quantize data of the second color component using the second offset.
