The invention relates to a system comprising a mobile device (1), a device (13b) for transmitting information, a device (15) hosting a device registry (14) and a wireless device (3a).

A system for managing a data stream between first and second networks is described in which a node entity transmits a data stream addressed to a destination device in the second network and a gateway entity receives the data stream from the first network.

A recipient UE (UE1) and a donor UE (UE2) are provided.

The invention relates to methods and systems for phase-based determination of a distance and/or a frequency offset between a first node and a second node in a wireless network.

A device (1) is configured to derive a first security key based on information relating to a first node (17), to request use of or to use a further device (9) as a relay to the mobile communication network and to determine whether the further device is connected to the first node and/or receive a message when another device, e.g. the first node, has determined that the further device is not connected to the first node.

A method is described for processing an omnidirectional video by a client device, said omnidirectional video being associated with a 3D coordinate system for determining a spatial position of video data of said omnidirectional video on a curved surface, preferably a sphere, said method comprising: receiving a manifest file, the manifest file comprising a plurality of tile stream identifiers for identifying a plurality of tile streams, the tile streams comprising video frames having image views, whereby the image views of video frames of different tile streams cover different regions of a 2D projection of the omnidirectional video, a region defining a tile; selecting on the basis of spatial relation information in the manifest file and on the basis of a viewpoint of a user of the client device a first tile streams associated with a first resolution and a first tile position and a second tile stream associated with a second resolution and a second tile position, the second resolution being lower than the first resolution, wherein the spatial relation information defines for each tile a tile position and wherein the viewpoint defines a viewing direction of the user, tile position and the viewpoint being defined on the basis of coordinates of the 3D coordinate system.

A processor system (200) processes image data from a camera (20) to render a virtual object in a 3D virtual environment and communicate via a network to a server system (300).

A system and method are provided for managing a concurrent streaming of a first media stream (031) and a second media stream (032).

The system of the invention is configured to receive from a client device (41) located in the mobile communication network (1) a request to connect to a home area network (5), determine an identifier of a residential gateway (61) in the home area network or of a fixed-line network (3) to which the home area network is coupled, and transmit a request for an address and a range of addresses in the home area network to the residential gateway or the fixed-line network corresponding to the determined identifier.

The service-providing device (11, 18, 19) of the invention is configured to obtain a code associated with the service-providing device, to wirelessly transmit the code, and to receive data from a service-using device (1,2) in response to the wireless transmission.

The invention relates to a method for controlling access for a user equipment to at least one local device via an intermediary system that is configured to connect to a local network and to a public network.

A system for sending a relay notification comprises a transceiver and a processor.

A software-implemented method for assisting in handling of connection setup requests in a telecommunications network is disclosed.

A method of determining a bitstream is described, including: determining a motion vector of a current block of a video frame of a sequence of video frames comprising video data captured by a video capturing device, the motion vector defining an offset of the current block relative to a prediction block of an already encoded first reference video frame, part of the offset being associated with global motion in the video data if the video capturing device is moving relative to a scene; determining a motion vector predictor selected by the processor from motion vectors of already encoded blocks of the current video frame; and, a motion compensation vector for the motion vector of the current block, for providing an estimate of the part of the motion vector that is associated with global motion; determining a global motion compensated motion vector based on a difference between the motion vector and motion compensation vector, and, a motion vector difference based on the motion vector predictor and the compensated motion vector; and, the processor using an entropy coding algorithm to code the motion vector difference; and, conversion information for converting the compensated motion vector into the motion vector, into a bitstream.

An intermediary system and method may be provided for assisting a receiver system in processing video data which is streamed as a video stream to the receiver system via a network.

A method of determining a bitstream is described, the method including: determining a motion vector (MV) of a current block of a current video frame of a sequence of video frames comprising video data captured by a camera, the MV defining an offset of the current block relative to a prediction block, wherein part of the offset is caused by global motion in the video data if the camera is moving relative to a scene; determining motion vector predictor MW candidates for predicting the MV, the MW candidates being determined based on MVs of already encoded blocks; determining a motion compensation vector MCV for MW candidates, determining global motion compensated MW candidates based on a difference between a MW candidate and an associated MCV; selecting a compensated MW; and, determining a motion vector difference MVD based on the compensated MW and the MW; and, using entropy coding to code, the MVD, an indication of the selected compensated MW; and, conversion information for converting a MVP into a compensated MW, into a bitstream.

A data processing system for a cellular communications network is disclosed.

A Method and a system for managing undesired service requests sent from at least one terminal to a network are described, wherein the network comprises a network node for storing trusted service-information.
