摘要： Media content is received for streaming to a user device. A neural network is trained based on a first portion of the media content. Weights of the neural network are updated to overfit the first portion of the media content to provide a first overfitted neural network. The neural network or the first overfitted neural network is trained based on a second portion of the media content. Weights of the neural network or the first overfitted neural network are updated to overfit the second portion of the media content to provide a second overfitted neural network. The first portion and the second portion of the media content are sent with associations to the first overfitted neural network and the second overfitted to the user equipment.

摘要： This specification describes a method comprising responding to a first gesture by a first user delimiting a visual virtual reality content portion from visual virtual reality content being consumed by the first user via a first head-mounted display by selecting the delimited visual virtual reality content portion, responding to a second gesture by the first user directed towards a content consumption device associated with a second user by identifying the content consumption device as a recipient of the selected visual virtual reality content portion, and causing the selected visual virtual reality content portion to be provided to the content consumption device for consumption by t second user.

摘要： A method for analyzing a presence of objects within a space provided with a capturing system comprising a plurality of camera devices and a playback system for reproducing audio and/or visual signals in the space, the method comprising obtaining a first 3D volumetric representation of a scene within the space, generated on the basis of input streams of at least a first and a second camera device, said first 3D volumetric representation showing at least one object within the scene; sending probe signals to a processing unit; controlling the processing unit to reproduce, using the playback system, one or more audio and/or visual signals on the basis of the probe signals into the space; controlling the processing unit to capture a second 3D volumetric representation of the scene including reproductions of the one or more audio and/or visual signals within the space; and analyzing the reproductions of the one or more audio and/or visual signals captured within the first space whether they correspond to a presumed location of the at least one object shown in the first 3D volumetric representation.

摘要： A method comprises providing video data representing at least part of virtual space to a user for viewing, identifying a current viewed sector of the virtual space based on user position, determining a sub-portion of said viewing sector, identifying an event occurring in a non-viewed sector of the virtual space, and displaying content indicative of the event in the sub-portion of said current viewing sector. The displaying step may comprise displaying a graphical notification of the event in the sub-portion, or in alternative embodiments, displaying video data showing the event in the sub-portion.

摘要： A method for operating a computer graphic system, the method comprising: inputting a media content object (MCO) into a feature extractor comprising semantic abstraction levels; extracting feature maps from said MCO on each of the semantic layers; selecting at least a portion of the MCO to be analysed; determining, based on the analysis of the feature maps from the portion of the MCO and the analysis of a previous state of a recognition unit, one or more feature maps selected from the feature maps of the semantic layers; determining a weight for each feature map; repeating the determining steps N times, each time processing, based on the analysis, each feature map by applying the corresponding weight; inputting said processed feature maps to the recognition unit; and analysing a number of said processed feature maps until a prediction about the portion of the MCO is output.

摘要： The embodiments relate to a method for encoding and a decoding, and apparatuses for the same. The method for encoding comprises receiving a block of a video frame for encoding (1510); making a decision on whether or not a learning-based model is to be applied as a processing step for encoding the block (1520); applying the learning-based model for said input block according to the decision, where the learning-based model has been selectively fine-tuned according to information relating to activation of the learning-based model of previously-decoded blocks (1530); encoding a signal corresponding to the decision on usage of the learning-based model into a bitstream (1540); and encoding the block into a bitstream with an information whether the block is to be used for finetuning (1550).
