A device may receive information associated with a plurality of cameras where each of the cameras has an associated camera object. The device may associate a first camera object with a first viewer. The first camera object may have associated first extrinsic properties and associated first intrinsic properties. The device may associate a second camera object with a second viewer. The second camera object may have associated second extrinsic properties and associated second intrinsic properties. The device may send a registration request to a Media Access Function (MAF) where the registration request identifies the first camera object and the second camera object. The first viewer and the second viewer may update their preferred views of media content, in response, the device may send an update request to the MAF, where the request comprises updated information associated with the first camera object and updated information associated with the second camera object.

Systems, devices, and methods are described herein for symmetric merge mode motion vector coding. Symmetric bi-prediction (bi-pred) motion vectors (MVs) may be constructed from available candidates in a merge candidate list for regular inter prediction merge mode and/or affine prediction merge mode. Available MV merge candidates may be symmetrically extended or mapped in either direction (e.g., between reference pictures before and after a current picture), for example, when coding a picture that allows bi-directional motion compensation prediction (MCP). A symmetric bi-pred merge candidate may be selected among merge candidates for predicting the motion information of a current prediction unit (PU). The symmetric mapping construction may be repeated by a decoder (e.g., based on a coded index of the MV merge candidate list), for example, to obtain the same merge candidates and coded MV at an encoder.

An example method in accordance with some embodiments may include: receiving a media manifest file identifying a plurality of representations of a multi-view video, at least a first representation of the plurality of representations comprising a first sub-sampling of views and at least a second representation of the plurality of representations comprising a second sub-sampling of views different from the first sub-sampling of views; selecting a selected representation from the plurality of representations; retrieving the selected representation; and rendering the selected representation.

A method for decoding or encoding includes obtaining views parameters for a set of views comprising at least one reference view and a current view of a multi-views video content wherein each view comprises a texture layer and a depth layer. For at least one couple of a reference view and the current view of the set of views, an intermediate prediction image applying a forward projection method to pixels of the reference view is generated to project these pixels from a camera coordinates system of the reference view to a camera coordinates system of the current view, the prediction image comprising information allowing reconstructing image data. At least one final prediction image obtained from at least one intermediate prediction image is stored in a buffer of reconstructed images of the current view. A current image of the current view from the images stored in said buffer is reconstructed, said buffer comprising said at least one final prediction image.

Systems and method for processing image content are described. In one embodiment, the method comprises receiving a plurality of captured contents showing same scene as captured by one or more cameras having a different focal length and depth maps and generating a consensus cube by obtaining depth map estimations from said received contents. The visibility of different objects in then analyzed to create a soft visibility cube that provides visibility information about each content. A color cube is then generated by using information from the consensus and soft visibility cube. The color cube is then used to combine different received contents and generate a single image for the plurality of contents received.

Some embodiments of an example method may include receiving an input image with depth information; mapping the input image to a set of focal plane images; orienting the set of focal plane images using head orientation information to provide stereo disparity between left and right eyes; and displaying the oriented set of focal plane images. Some embodiments of another example method may include: receiving a description of three-dimensional (3D) content; receiving, from a tracker, information indicating motion of a viewer relative to a real-world environment; responsive to receiving the information indicating motion of the viewer, synthesizing motion parallax by altering multi-focal planes of the 3D content; and rendering an image to the multi-focal plane display using the altered multi-focal plane rendering.

A device may receive information associated with a plurality of cameras where each of the cameras has an associated camera object. The device may associate a first camera object with a first viewer. The first camera object may have associated first extrinsic properties and associated first intrinsic properties. The device may associate a second camera object with a second viewer. The second camera object may have associated second extrinsic properties and associated second intrinsic properties. The device may send a registration request to a Media Access Function (MAF) where the registration request identifies the first camera object and the second camera object. The first viewer and the second viewer may update their preferred views of media content, in response, the device may send an update request to the MAF, where the request comprises updated information associated with the first camera object and updated information associated with the second camera object.
