摘要： Processor systems and computer-implemented methods are provided for rendering a multiuser virtual environment in which different panoramic images are provided as image-based backdrop for different viewing positions in the virtual environment. When a user switches from a first viewing position for which a first panoramic image is rendered to a second viewing position for which a second panoramic image is rendered, a transition may be rendered for the user, for example as a mathematical transformation of the panoramic images. To avoid other users perceiving the representation of the user in the virtual environment from abruptly switching to the second viewing position, transition data may be provided which enables another processor system to render a representation of the transition in the virtual environment, e.g., by moving an avatar of the user along a movement trajectory.

摘要： A method for enhancing a region of interest in video frames of a video stream is described. The method includes receiving media data defining base video frames of at least one base stream, said base stream being associated with one or more enhancement tile streams, an enhancement tile stream comprising media data defining tiled video frames comprising a tile, said tile comprising media data for enhancing visual content in a subregion of the image region of the base video frames; requesting media data of one or more enhancement tile streams, preferably one or more HEVC enhancement tile streams, the one or more enhancement tile streams being associated with media data for enhancing visual content in the at least one region of interest; generating base video frames on the basis of media data of the at least one base stream and generating tiled video frames on the basis of media data of the one or more enhancement tile streams, the tiled video frames comprising one or more tiles forming visual content the at least one region of interest; and, replacing or blending at least part of the visual content of said at least one region of interest in the video frames of said base stream with at least part of said enhanced visual content of the tiled video frames.

摘要： Method for processing audio objects by an client apparatus is described wherein the method comprises:
receiving or determining spatial listener information, the spatial listener information defining including one or more listener positions, orientations and/or foci of one or more listeners in the audio space; the client apparatus selecting one or more audio object identifiers from a set of audio object identifiers defined in a manifest file stored in a memory of the client apparatus, an audio object identifier defining an audio object being associated with audio object position information for defining one or more positions of the audio object in the audio space; the selecting of the one or more audio object identifiers by said client apparatus being based on the spatial listener information and the audio object position information of audio object identifiers in said manifest file; and, the client apparatus using said one or more selected audio object identifiers to request transmission of audio data and audio object metadata associated with the one or more audio objects defined by the selected audio object identifiers to said client apparatus.

摘要： A system is described for managing service interactions in a combined service. The system comprises a first service delivery means for providing a first service, a second service delivery means for providing a second service, a combined service delivery means for providing a combined service capable of associating the first service to one of the second service. The combined service is implemented using a combined state model, which comprises a predetermined number of combined states formed on the basis of the states of the first and the second service and armed detection points for detecting predetermined transitions between the combined states. The combined service delivery means further comprises a combined state manager adapted to transmit a control signal to the first and/or the second service delivery means for inducing a predetermined state transition in the respective first and/or the second service in response to the activation of an armed detection point.
