Abstract: Systems and methods for coding video information for a current view based on a residual prediction from video information for a reference view are described. In one innovative aspect, an apparatus for coding digital video is provided. The apparatus includes a memory configured to store current view video information and reference view video information. The apparatus also includes a processor configured to determine a value of a current video unit of the current view based at least on a motion compensated block of the reference view. The motion compensated block may be determined based at least in part on motion information and a disparity vector associated with the current video unit. Decoding devices and methods as well as corresponding encoding devices and methods are described.

Abstract: A video coder determines a first picture order count (POC) value of a first reference picture associated with a first motion vector of a corresponding block that points in a first direction and determines whether a first reference picture list for the current block includes a reference picture having the first POC value; in response to the reference picture list not including the reference picture having the first POC value, determines a second POC value of a second reference picture associated with a second motion vector of the corresponding block that points in a second direction, determines whether the first reference picture list for the current block includes a reference picture having the second POC value and in response to the first reference picture list including the reference picture having the second POC value, decodes the current motion vector using the second motion vector of the corresponding block.

Abstract: When coding multiview video data, a video coder can code one or more pictures in one or more reference views, including a first reference view and determine a disparity vector for a current block based on motion information of one or more neighboring blocks of the current block, wherein the current block is in a second view, wherein the disparity vector points from the current block to a corresponding block in a picture of the same time instance in one of the one or more reference views.
