A method is described for providing one or more tile streams to a client device for rendering a region-of-interest (ROI), wherein said ROI defines a region of a tile representation of a source video and wherein said method comprises: rendering a region-of-interest (ROI) video stream comprising a ROI of said source video; receiving ROI position information of at least one frame of said ROI video stream; and, receiving one or more tile streams that are requested the basis of said ROI position information and a spatial manifest file, said spatial manifest file defining one or more tile representations of said source video, a tile representation comprising one or more tile identifiers for identifying one or more tile streams and a tile position information defining the spatial position of said tile streams.

Methods and devices are provided for use in a streaming process (130) of a Virtual Reality [VR] video to a VR rendering device (120).

The invention relates to a network node (15) comprising at least one communication interface, at least one memory, and at least one processor.

Methods and systems are described for forming one or more tile streams comprising: providing media data of at least one composite video stream to the input of at least one encoder, the media data of said composite video stream representing video frames comprising an image region having one or more subregions, each of said one or more subregions comprising visual content of one of said one or more video streams; providing encoder information to said encoder for configuring said encoder to generate encoded media data representing tiled video frames, a tile in said tiled video frames matching at least one of said one or more subregions; encoding media data of said composite video stream, wherein media data associated with a subregion of a video frame are encoded into independently encoded media data that have no spatial decoding dependency on media data of other subregions in said video frame, said independently encoded media data forming a tile of a tiled video frame, preferably said tile being arranged in said image region on the basis of a tile grid; and, storing said encoded media data as one or more tile streams on a storage medium, preferably on a storage medium of one or more network nodes, a tile stream comprising media data of at least one tile and tile position information for signaling a decoder to decode the media data of said tile stream into tiled video frames comprising a tile at a position as indicated by the tile position information.

One aspect of the disclosure relates to a method in a user equipment for instructing establishment of a connection between a first local device and a second local device, the user equipment being connected to a public network, wherein an intermediary system is configured to connect to a first local network, to a second local network and to the public network.

A method is described of streaming HEVC-tiled video data to a client device comprising: providing said client device with a spatial manifest file comprising one or more spatial segments identifiers for locating one or more delivery nodes configured for delivering video data associated with a spatial segment identified by at least one of said one or more spatial segments identifiers, preferably (part of) one or more URLs, to said client device, a spatial segment being associated with HEVC-tiled video data comprising a subset of HEVC tiles of a HEVC-tiled (panorama) video stream; and, selecting a spatial segment identifier in said spatial manifest file for requesting a delivery node to deliver at least part of the video data of a spatial segment as a HEVC-tiled video stream to the client device.

A system is provided for enabling correlating timeline information between a first media stream and a second media stream which are both associated with a common play-out timeline.

A method for enhancing a region of interest in video frames of a video stream is described.

A method for an intermediary node to reduce a number of server-client sessions between a server (104) and a plurality of clients (102a, 102b, 102c) communicably connected to the server (104) over a network is disclosed.

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.

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.

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.

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