Motion vector prediction with motion vectors from multiple views in multi-view video coding

摘要

Aspects of this disclosure relate to, in an example, a method that includes identifying a first block of video data in a first temporal location from a first view, wherein the first block is associated with a first disparity motion vector. The method also includes determining a motion vector predictor for a second motion vector associated with a second block of video data, wherein the motion vector predictor is based on the first disparity motion vector. When the second motion vector comprises a disparity motion vector, the method includes determining the motion vector predictor comprises scaling the first disparity motion vector to generate a scaled motion vector predictor, wherein scaling the first disparity motion vector comprises applying a scaling factor comprising a view distance of the second disparity motion vector divided by a view distance of the first motion vector to the first disparity motion vector.

1. A method of coding video data, the method comprising:
identifying a first block of video data in a first temporal location from a first view, wherein the first block is associated with a first disparity motion vector; generating a motion vector predictor candidate list for predicting the first disparity motion vector, wherein generating the motion vector predictor candidate list comprises:
identifying a second motion vector for a second block of video data in a second view, wherein the second view is different than the first view;based on the second motion vector being a disparity motion vector, adding the second motion vector to the motion vector predictor candidate list;based on the second motion vector not being a disparity motion vector, determining that the second motion vector is unavailable for motion vector prediction such that the second motion vector is not added to the candidate list; andadding at least one other disparity motion vector to the motion vector predictor candidate list, wherein the at least one other disparity motion vector includes a disparity motion vector from a third block in a second temporal location from the first view; and coding prediction data for the first block using a motion vector predictor from the motion vector predictor candidate list.
