摘要： A method for encoding a video signal. The method comprises receiving encoding instructions for encoding the video signal and encoding the video signal using a training loop for optimizing a metric of the encoded video signal, wherein the training loop comprises a loss function and one or more of a neural encoder and a neural decoder. The training loop is adapted based on the encoding instructions.

摘要： A method for encoding a layered video signal with a first layer and a second layer, wherein second layer is dependent on the first layer. The method comprises encoding the first layer and the second layer, wherein at least one of the first layer and the second layer are encoded using neural coding and the first layer is encoded using a first loss function for optimizing a first metric and the second layer is encoded using a second, different, loss function for optimizing a second metric. The method further comprises obtaining decoding parameters for decoding the first layer and the second layer and transmitting and/or storing the encoded base layer and encoded enhancement layer with the decoding parameters.

摘要： A method for encoding immersive video. The method comprises obtaining video sequences of a scene, analyzing the video sequences for temporally redundant data between frames of the video sequences and determining at least one temporal level of detail, TLoD, value for each video sequence based on the analysis. The TLoD values are indicative of an amount of temporal redundancy in the video sequences. The video sequences are encoded with temporal encoding parameters determined based on the corresponding TLoD values.

摘要： A method for transmitting multi-view image frame data. The method comprises obtaining multi-view components representative of a scene generated from a plurality of sensors, wherein each multi-view component corresponds to a sensor and wherein at least one of the multi-view components includes a depth component and at least one of the multi-view components does not include a depth component. A virtual sensor pose is obtained for each sensor in a virtual scene, wherein the virtual scene is a virtual representation of the scene and wherein the virtual sensor pose is a virtual representation of the pose of the sensor in the scene when generating the corresponding multi-view component. Sensor parameter metadata is generated for the multi-view components, wherein the sensor parameter metadata contains extrinsic parameters for the multi-view components and the extrinsic parameters contain at least the virtual sensor pose of a sensor for each of the corresponding multi-view components. The extrinsic parameters enable the generation of additional depth components by warping the depth components based on their corresponding virtual sensor pose and a target position in the virtual scene. The multi-view components and the sensor parameter metadata is thus transmitted.

摘要： An apparatus comprises a receiver (301) receiving an image signal representing a scene. The image signal includes image data comprising a number of images where each image comprises pixels that represent an image property of the scene along a ray having a ray direction from a ray origin. The ray origins are different positions for at least some pixels. The image signal further comprises a plurality of parameters describing a variation of the ray origins and/or the ray directions for pixels as a function of pixel image positions. A renderer (303) renders images from the number of images based on the plurality of parameters.
