    Abstract: A device performs a disparity vector derivation process to determine a disparity vector for a current block. As part of performing the disparity vector derivation process, when either a first or a second spatial neighboring block has a disparity motion vector or an implicit disparity vector, the device converts the disparity motion vector or the implicit disparity vector to the disparity vector for the current block. The number of neighboring blocks that is checked in the disparity vector derivation process is reduced, potentially resulting in decreased complexity and memory bandwidth requirements.

    Abstract: A method of coding video data includes deriving prediction weights for illumination compensation of luma samples of a video block partition once for the video block partition such that the video block partition has a common set of prediction weights for performing illumination compensation of the luma samples regardless of a transform size for the video block partition, calculating a predicted block for the video block partition using the prediction weights using illumination compensation, and coding the video block partition using the predicted block.

    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. The video encoder and video decoder may determine whether a block in the selected candidate picture is inter-predicted with a disparity motion vector and determine a disparity vector for a current block of a current picture based on the disparity motion vector. The video encoder and video decoder may inter-prediction encode or decode, respectively, the current block based on the determined disparity vector.

    Abstract: A video decoder may adaptively disable, based on a syntax element, one or more filters used for intra-prediction. In addition, the video decoder may perform intra-prediction to generate prediction data for a current block of a current video slice. Furthermore, a video encoder may adaptively disable one or more filters used for intra-prediction. Furthermore, the video encoder may signal a syntax element that controls the one or more filters. In addition, the video encoder may perform intra prediction to generate prediction data for a current video block the video data.

    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.
