    摘要： A method performed by a video encoder for encoding a current picture belonging to a temporal level identified by a temporal_id. The method includes determining a Reference Picture Set (RPS) for the current picture indicating reference pictures that are kept in a decoded picture buffer (DPB) when decoding the current picture, and when the current picture is a temporal switching point. The method further comprises operating to ensure that the RPS of the current picture includes no picture having a temporal_id greater than or equal to the temporal_id of the current picture.

    摘要： Methods, systems, and computer readable media for transcoding video data based on metadata are provided. In some embodiments, methods for transcoding video data using metadata are provided, the methods comprising: receiving a first plurality of encoded images from a storage device; decoding the first plurality of encoded images based on a first coding scheme to generate a plurality of decoded images; receiving a plurality of encoding parameters from the storage device; and encoding the plurality of decoded images into a second plurality of encoded images based on a second coding scheme and the plurality of encoding parameters.

    摘要： A method of controlling intra prediction for decoding or encoding of a video sequence, is performed by at least one processor and includes obtaining intra prediction modes including directional modes respectively corresponding to angular prediction directions, a first amount of one or more of the directional modes being excluded from the intra prediction modes based on a second amount of the intra prediction modes and a third amount of most probable modes (MPMs). The method further includes selecting, as the MPMs, two or more of the intra prediction modes from which the one or more of the directional modes are excluded, and selecting, for decoding the video sequence, one of the intra prediction modes from which the one or more of the directional modes are excluded.

    摘要： Example methods and apparatus for adaptive video transmission based on channel capacity are disclosed. A first wireless display source device for adaptive video transmission based on channel capacity includes a video bit rate determiner, a comparer and a video bit rate setter. The video bit rate determiner is to determine a collective video bit rate based on a current number of wireless display connections in a peer-to-peer (P2P) group multiplied by a current video bit rate of the first wireless display source device. The P2P group includes a second wireless display source device in proximity to the first wireless display source device. The comparer is to compare the collective video bit rate to a wireless display capacity in proximity to the first wireless display source device. The video bit rate setter is to set the current video bit rate of the first wireless display source device to a first adjusted video bit rate value in response to the comparer determining that the collective video bit rate is greater than the wireless display capacity, and to set the current video bit rate of the first wireless display source device to a second adjusted video bit rate value in response to the comparer determining that the collective video bit rate is not greater than the wireless display capacity.

    摘要： A sequence of point clouds is encoded as a video by an encoder and transmitted to a decoder which retrieves the sequence of point clouds. Visible points of a point cloud are iteratively projected on projection maps according to at least two centers of projection, to determine a patch data item lists. One of the centers of projection is selected and corresponding image patches are generated and packed into a picture. Pictures and associated patch data item list are encoded in a stream. The decoding method decodes pictures and associated patch data item lists. Pixels of image patches comprised in pictures are un-projected according to data stored in associated patches. The methods have the advantage of encoding every point of point clouds in a manner avoiding artifacts and allowing decoding at video frame rate.
