Koninklijke KPN (KKPNY) USPTO patents

Methods and systems are described for retrieving segmented content originating from two or more content delivery networks.

The invention relates to a mobile communication system.

Methods and systems enabling the end users of cellular devices to set up infrastructure-based D2D connections with other devices from within the over-the-top (OTT) applications running on their devices are disclosed.

Methods and systems for enabling streaming of segmented content from a content delivery network to an adaptive streaming client on the basis of a manifest file are described wherein the said manifest file may comprise one or more segment identifiers.

A user device (15) may be arranged to control insertion of personalized content into multicast content.

The disclosure relates to a computer-implemented method for controlling on-demand service provisioning in a network, wherein the network comprises resources for providing a service.

A method for processing spherical video data is described including a data processor providing spherical video data in the form of projected video frames to an input of an encoder process, a projected video frame including one or more pixel regions, the one or more pixel regions representing pixels of spherical video data projected onto one or more 2D projection surfaces of a projection model, preferably an equirectangular or a 3D polyhedron projection model, for projecting spherical video data onto a rectangular 2D surface of a video frame; wherein the providing of spherical video data may comprise: generating a set of modified projected video frames on the basis of a projected video frame, the generating including applying different shift and/or rotation operations to pixels, preferably one or more pixel regions, of the selected projected video frame; applying an image analysis algorithm to the modified projected video frames, the image analysis algorithm determining an image analysis parameter for a least part of the modified projected video frames, the image analysis parameter being indicative for the encoding efficiency and/or image quality; and, selecting a modified projected video frame from the set of modified projected video frames, the selected modified projected video frame being associated with an image analysis parameter indicative of the best encoding efficiency and/or image quality.

The invention relates to methods of enabling a media orchestration.

The invention relates to a method, a system and various components of such a system for selecting a chunk identifier in a content delivery network.

Methods and systems are described for enabling network-initiated control of streaming of segmented content from a content delivery node to at least one client, the client being configured to access at least part of the segmented content on the basis of a manifest file.

A system and method are provided for determining a size of a virtual object in a virtual environment.

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

Methods and devices are provided for use in streaming a Virtual Reality [VR] video to a VR rendering device.

A method for selectively updating a dynamic manifest file is described, wherein the method may comprise: selecting one or more metadata elements of a manifest file used by a client, the one or more selected metadata elements being associated with a subset of representations of the set of representations defined in the manifest file; transmitting a request message identifying the selected one or more metadata, and, optionally, said manifest file identifier, to a network node, the request message being configured to trigger the network node to generate a response message on the basis of the information in the request message; and, receiving the response message from the network node, wherein the response message comprises: location information, preferably an URL or a part thereof, for retrieving a selectively updated version of the dynamic manifest file used by the client, wherein the selectively updated version only comprises new segment identifiers associated with the one or more selected metadata elements; or, wherein the response message comprises: update information, preferably a patch, configured to selectively update the dynamic manifest file used by the client apparatus, wherein the update information only comprises new segment identifiers associated with the one or more selected metadata elements.

The invention relates to a telecommunications system comprising at least a plurality of SA-cells.

A method of establishing a connection between a remote User Equipment, UE, and a telecommunication network via a relay capable UE, wherein said telecommunication network comprises a core network and an access network, and wherein said connection is established using a Remote Radio Access Bearer between the remote UE, via a relay capable UE, via an access node in the access network, and the core network.

A method is described of probing a network route using a pairs of probe packets in which the first packets are typically smaller than the second.

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.
