A method for adaptive streaming of video is described, wherein the method comprises: transmitting first metadata to a client apparatus, the first metadata defining a first adaptation set, an adaptation set defining one or more sets of segment identifiers, each set of segment identifiers defining a plurality of linearly playable media segments of a predetermined resolution, each media segment in a set of media segments having an identical playback duration, the first metadata enabling a client apparatus to request media segments and sequentially playout the media segments; receiving navigation information from the client apparatus, the navigation information defining at least a first region, in the video frames of the first adaptation set; selecting second metadata defining a second adaptation set on the basis of spatial playback information and a spatial distance or a spatial overlap between the first region and a second region in video frames of the first adaptation set, wherein the spatial playback information signals the server apparatus that the second region is linked to media segments of the second adaptation set; and, transmitting the second metadata or information for retrieving the second metadata to the client apparatus, the second metadata enabling the client apparatus to playback media segments of the second adaptation set after the playback of media segments of the first adaptation set.

A receiving system (1) is configured to determine reception antenna weights for a plurality of antennas and/or antenna elements for each transmitting system of a plurality of transmitting systems (11, 22-65) for receiving wireless signals using receive beamforming.

A projection metadata system and method are provided for providing projection metadata to a rendering system for use in rendering a panoramic scene.

A method is described of forming a bitstream by an encoder apparatus comprising: a processor of the encoder apparatus receiving 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, the projection model being adapted to project spherical video data onto a rectangular 2D surface of a video frame; the processor generating a plurality of different candidate video frames on the basis of the received projected video frame, each candidate video frame being formed by applying at least one operation to one or more groups of pixels in one or more pixel regions of the projected video frame, wherein said at least operation includes a shift, mirror and/or rotation operation; and, wherein said operation is different for each of said plurality of different candidate video frames; the processor applying a rate distortion analysis to each of the candidate video frames to determine a rate distortion cost for each of the candidate video frames; and, the processor selecting a candidate video frame from said plurality of candidate video frames on the basis of the rate distortion cost; and, generating an output bitstream on the basis of the selected candidate video frame.

Methods and systems are disclosed enabling establishment of a direct connection between a first device connected to a first network and a second device connected to a second network upon finding a permission response from a third device connected to a third network.

A method comprises listening (151) for transmission of a preamble by a transmitting device to a recipient and receiving (153) data in a second time interval upon receiving the preamble in a first time interval.

In a communication network with separate data planes including a control plane and a user plane, an application function is provided as a combination of an application function control plane (AF-CP) part operating in the network's control plane and an application function user plane (AF-UP) part operating in the network's user plane.

In a communication network, a network function may be provided for controlling Information Centric Networking (ICN) protocol-based traffic flow between a set of user equipment (UE).

Embodiments provide functionality for dynamic handling of network slice priorities.

Encoded video data representing partial video images is decoded from a first video stream such as a HEVC bitstream.

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 content distribution system is provided comprising a content client and a content server connected through a network.

Some embodiments are directed to a blockchain verification method for a secondary blockchain, the blockchain verification method including sending an activation transaction to a primary blockchain management device which is configured to manage the primary blockchain.

A first method comprises transmitting (101) a preamble in a first time interval in a first frequency resource, transmitting (103) a first portion or a first copy of data in the first frequency resource in a second time interval, and transmitting (105) a second portion or second copy of the data in a second frequency resource in the second time interval.

Systems and methods for screen sharing are provided.

A client device (13) is configured to transmit a relay request to a relay device (14).

A client device is facilitated to synchronize streaming and processing a second stream to streaming and processing a first stream.
