  • Publication number: 20240080501
    Abstract: A method of processing multi-view video data by an server is described, wherein the method may comprise receiving one or more first multi-view parameters from a client device, the one or more multi-view parameters being indicative of a first data format associated with a multi-view display device of the client device; receiving a request for a segment sent by the client device based on a manifest file, the segment request comprising a segment resource locator identifying a first source segment comprising first multi-view video data, the segment resource locator comprising one or more second multi-view parameters indicating that the first multi-view video data are of a second data format; generating a segment of the first data format based on the one or more first multi-view parameters, the first multi-view video data and, optionally, further multi-view video data associated with one or more further source segments; and, transmitting the generated segment to the client device.

  • Publication number: 20240070924
    Abstract: A compression system is configured to obtain a plurality (231) of two-dimensional arrays (234-239) of element values, e.g. a plurality of video frames. Same positions in different arrays comprise a value of the same element at a different moment. The compression system is further configured to convert the plurality of two-dimensional arrays of element values to a three-dimensional point cloud (232), which comprises a plurality of data points, by mapping the positions of the element values in the plurality of two-dimensional arrays to coordinates of the data points and associating each of the element values with a corresponding data point in the point cloud. The compression system is further configured to apply geometry-based point cloud compression to the three-dimensional point cloud.

  • Publication number: 20240064317
    Abstract: A method of decoding coded pictures of a video is described wherein the method includes the steps of receiving, by a decoder apparatus, a bitstream comprising an encoded representation of first pictures of a first resolution version of the video and decoding the coded first pictures into first pictures, the first pictures being associated with corresponding second pictures of a second resolution version of the video, the first pictures being formed by sampling the corresponding second pictures using a sampling lattice of a plurality of sampling lattices of a spatial subsampling scheme; receiving, by the decoder apparatus, signalling information in the bitstream, the signalling information informing the decoder apparatus about a resolution change and identifying at least one of the first pictures as a first base picture and identifying one or more auxiliary pictures, the first base picture being associated with a corresponding second picture, and, each of the one or more auxiliary pictures being formed based o

  • Publication number: 20240056614
    Abstract: Methods and apparatus for processing an encoded representation of a sequence of pictures are disclosed, wherein the method includes: allocating memory for a current picture of the sequence of pictures in a decoded picture buffer, DPB; receiving a bitstream comprising an encoded representation of the current picture, and storing the encoded representation as a plurality of decoding units DUs, in a coded picture buffer, CPB, each of the plurality of DUs comprising an encoded set of pixels, wherein no coding dependency exists between coded pixels of different DUs of the current picture; receiving prioritization information associated with each of the plurality of DUs stored in the CPB, the prioritization information defining a decoding order in which the DUs of the current picture are being decoded; decoding one or more of said plurality of DU's into one or more decoded DU's, in accordance with said decoding order, each decoded DU comprising a set of pixels, each set of pixels being associated with a different a

  • Publication number: 20230379554
    Abstract: A method of processing a multi-view video by a client apparatus is described wherein, the multi-view video comprising a set of video streams is created by a set of cameras simultaneously capturing an object in a scene for a set of view angles and for one or more video resolutions, each video stream defining a view associated with a view angle of a camera relative to the object.
