Koninklijke KPN (KKPNY) USPTO patents

Systems and methods for screen sharing are provided.

A system and method for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein said generating of the display data comprises rendering the video stream in a sub-area of the visible display area.

Methods and systems for enabling content distribution from a first device to a second device are disclosed.

The client device (1) of the invention is configured to receive service information from a first network device (19) in a first communication network, determine time periods (71) from the service information and transmit client information to a second network device (11) in a second communication network.

Systems and methods are provided for generating and rendering an enhanced audiovisual recording of a user, which may be used for multiuser communication, e.g., in Virtual Reality.

The invention relates to a method for establishing a communication service with a user equipment in the coverage area of a base station is disclosed.

The invention relates to a system and method of transferring user data from a communication module to a data processing center over a telecommunications network.

The system (1) of the invention is configured to receive information relating to relay devices (11,17-19) present in a certain spatial area and determine relay configuration information for the relay devices from the information.

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.

A method for processing spherical video data is described comprising: receiving region of interest (ROI) information associated with a ROI in a spherical representation of video data, the ROI information including a spherical ROI coordinate associated with a position of the ROI; receiving a manifest file comprising one or more tile stream identifiers for identifying one or more tile streams, each tile stream comprising spherical video data of a tile on the spherical surface, each tile defining a subpart on the spherical surface, the manifest file further comprising spatial description information for signaling the client apparatus information on the position of the tiles on the spherical surface; receiving projection information for signaling the client apparatus about the type of projection that is used for projection of the spherical video data onto a planar surface; and, receiving and/or generating boundary information for defining the boundary of the ROI on the basis of the spherical ROI coordinate, and, using the ROI area for selecting one or more tile streams on the basis of the spatial description information and the projection information, wherein each of the selected tile streams defines a tile on the sphere that overlaps with the ROI area.

The invention relates to a node for communication between a first network and an second network and coupled to a controller in the second network via a first communication route.

A method of facilitating capturing visual information at a first location (1) for display at a second location (2) is disclosed.

The invention relates to a method for establishing a communication service with a user equipment in the coverage area of a base station is disclosed.

A system (1) is configured to select candidate sets of cell groups from a collection of sets of cell groups and arrange transmission of one or more messages to multiple mobile devices (11-15).

A method of forming a video signal by a decoder device is described wherein the method comprises receiving a bitstream and decoder information, the decoder information signaling the decoder device the presence of one or more resolution components in the bitstream for forming a video signal, a resolution component representing a spatially subsampled version, preferably a polyphase subsampled version, of a first video signal having a first resolution, the one or more resolution components being part of a resolution component group, the group comprising a plurality of resolution components on the basis of which the first video signal is reconstructable; and, the decoder device parsing the bitstream and decoding the one or more resolution components into video frames on the basis of the decoder information.

A method and stream modifier are provided for pre-processing a primary media stream for a user device.

Embodiments of the present disclosure provide a solution that guarantees authenticity and integrity on the signaling exchange between mobile roaming networks that trust each other.

Some embodiments are directed to a blockchain management no device (100) configured to apply a symmetric hash function over multiple transactions received over the communication interface thus obtaining a hash value, and to generate a consensus proof over at least the hash value, and to assemble a new block (240) for inclusion in the blockchain.
