Patent number: 11563970Abstract: A block of video data that is split into sub-blocks forms a prediction for that sub-block using predictions from neighboring sub-blocks such that a current prediction for the sub-block is combined with weighted versions of the neighboring predictions. The neighboring sub-blocks motion vectors are checked to determine whether they are different than the motion vector of the sub-block being predicted. If so, than that corresponding neighboring sub-block is used to generate the prediction of the current sub-block. In an embodiment, two lines or two columns of pixels within a sub-block are used in forming the prediction for the current sub-block when the size of the block containing the sub-block is under a particular size.Type: GrantFiled: February 22, 2019Date of Patent: January 24, 2023Assignee: INTERDIGITAL VC HOLDINGS, INC.Inventors: Antoine Robert, Fabrice Leleannec, Tangi Poirier

Patent number: 11533492Abstract: A method for inter-coding video is provided in which transmission bandwidth requirements associated with second motion vectors for bi-directional temporal prediction is reduced. In the method motion vector information for only one of the two motion vectors for bi-directional temporal prediction can be transmitted together with information on how to derive or construct the second motion vector.
