  • Patent number: 11463852
    Abstract: The disclosure relates to a message distribution system configured to provide traffic messages received by at least one base station of a telecommunications network to at least one traffic control system capable of controlling traffic infrastructure. The message distribution system comprises a detection module and a routing module. The detection module is configured to detect traffic messages from user devices in a radio coverage area of the at least one base station. The routing module is configured to access association information associating at least one routing address of the at least one traffic control system with the radio coverage area of the at least one base station and to route the detected traffic messages to the at least one routing address associated with the radio coverage area of the at least one base station receiving the traffic messages from the user devices.

  • Patent number: 11461942
    Abstract: 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.

  • Patent number: 11450071
    Abstract: A method and processor system are provided for adapting an acoustic rendering of an audio source to a visual rendering of an image-based object. Such visual rendering may be in virtual-reality (VR) or in augmented-reality (AR). The image-based object may be modelled, and an audio object representing the modelled object may be established in an acoustic scene containing the audio source and being associated with the visual rendering. The audio object may be assigned a reverberant and/or absorbent property, and the acoustic rendering may be adapted to the audio object. This way, the acoustic rendering may be adapted to image-based objects, and a user may perceive the acoustic rendering as better matching the visual rendering.

  • Patent number: 11438660
    Abstract: The invention is concerned with insertion of secondary content in a time slot of primary content. The primary content and the secondary content are provided to a receiver via a managed content delivery network configured for IPTV delivery. The secondary content may be personalized content, such as an ad. Both the primary content and the secondary content may be encrypted, and decryptable with different decryption keys. Measures are described for pre-caching the decryption key for the secondary content at the receiver ahead of a scheduled play-out time of the secondary content. By pre-caching the decryption key, an interruption in play-out may be avoided or reduced compared to a basic scenario in which the receiver requests the decryption key at or immediately before the scheduled play-out time.

  • Patent number: 11375284
    Abstract: An improved streaming of a Virtual Reality [VR] video to a VR rendering device is provided. The VR video may be represented by a plurality of streams each associated with a different view of a scene. A view of the scene may be determined which is to be rendered by the VR rendering device. A subset of streams may be identified which is needed to render the view of the scene. The streaming of the subset of streams to the VR rendering device may be effected by streaming the plurality of streams from a stream source to a forwarding node downstream of the stream sources and upstream of the VR rendering device, and selectively forwarding the subset of streams from the forwarding node to the VR rendering device in response to the view having to be rendered by the VR rendering device. As such, the switching latency between streams may be reduced.

  • Patent number: 11316934
    Abstract: One aspect of the disclosure relates to a method for providing a service to a user equipment connected to a first operator network. The second operator network comprises a register containing subscription information of the user equipment. The method comprises a number of steps. One of these steps is receiving from the first operator network a service request of the user equipment, the service request being associated with the service. Another step is obtaining a service-deployment-specification for the second operator network comprising at least one network function associated with the service on the basis of the service request. Yet another step is converting the service-deployment-specification for the second operator network into a generic specification, the generic specification enabling execution of the at least one network function in the first operator network for providing the service to the user equipment. Yet another step is transmitting the generic specification to the first operator network.

  • Patent number: 11265359
    Abstract: A system and method are provided for managing a concurrent streaming of a first media stream (031) and a second media stream (032). The media streams (031, 032) represent different recordings of an event. The concurrent streaming of the media streams (031, 032) is enabled by a resource having a resource limitation (080). To address this resource limitation, when it is determined that the resource limitation is exceeded by the concurrent streaming of the first media stream (031) streaming to a first streaming client (041) and the second media stream (032) streaming to a second streaming client (042), the first media stream (031) is selected for substituting the second media stream (032) in the streaming to the second streaming client (042). As a result of the substitution, the first and the second streaming client (041, 042) stream the same media stream rather than different media streams.
