    Abstract: A client device (CLD) for a mobile network may comprise two radios (R-1, R-2) for establishing simultaneous mobile data connections to at least two mobile networks, for example at a country border at which the client device leaves the network range of one mobile network and enters the network range of another. The client device may further be configured to utilize an edge application service (EDG-APP) of a mobile network. To coordinate the switch in connectivity and edge utilization between such different mobile pp networks, a client function (CDCF) may be provided in the client device while separate instances of a network function (EDCF) may be provided in each edge enabling platform of each mobile network. Together, the CDCF and the EDCFs may orchestrate the migration of the edge application service between the mobile networks, in a manner which respects the requirements for separation of concerns, e.g., between a mobile network's operator and an application service provider (ASP).

    Abstract: An orchestration system and method are described for at least in part orchestrating a multidevice video session in which a plurality of devices each transmit a video, for example of a user, via a network and in which a composition system receives said transmitted videos and composites, for a respective device from the plurality of devices, videos of other devices into one or more video streams and transmits the one or more video streams via the network to the device. A grouping of the users/devices may be determined to allow the video stream(s) to be generated for respective devices in a manner which may be dependent on the group to which they are deemed to belong. In particular, the video stream(s) may be generated by the composition system such that the videos of devices within a same group are shown in a better quality than the videos of devices from another group, as a user of a device may prefer to see the users from the same group in a better quality than the users from another group.

    Abstract: A gateway system is described for use as a gateway between a client device and a remote server. The client device may stream a data stream via the gateway system to the remote server for remote processing. The gateway system may receive the data stream and markers which identify respective blocks of packets in the data stream, wherein each identified block of packets is independently processable. In response to an instruction or configuration to effect a migration of the remote processing from the remote server to a further remote server, the gateway system may determine a block of packets in the data stream from which block of packets onwards the further remote server is to start processing the data stream so as to effect or initialize the migration, and when received, stream the determined block of packets and subsequent blocks of packets of the data stream to the further remote server.

    Abstract: A method of decoding coded pictures of a video is described wherein the method includes the steps of receiving, by a decoder apparatus, a bitstream comprising an encoded representation of first pictures of a first resolution version of the video and decoding the coded first pictures into first pictures, the first pictures being associated with corresponding second pictures of a second resolution version of the video, the first pictures being formed by sampling the corresponding second pictures using a sampling lattice of a plurality of sampling lattices of a spatial subsampling scheme; receiving, by the decoder apparatus, signalling information in the bitstream, the signalling information informing the decoder apparatus about a resolution change and identifying at least one of the first pictures as a first base picture and identifying one or more auxiliary pictures, the first base picture being associated with a corresponding second picture, and, each of the one or more auxiliary pictures being formed based on sampling the second picture using a different sampling lattice of the plurality of sampling lattices; receiving, by the decoder apparatus, an encoded representation of the one or more auxiliary pictures in the bitstream, decoding the encoded representation of the one or more auxiliary pictures into one or more auxiliary pictures and constructing a reference picture of the second resolution based on the first base picture and the one or more auxiliary pictures; and, receiving, by a decoder apparatus, an encoded representation of second pictures in the bitstream and decoding at least part of the encoded representation of the second pictures into one or more second pictures using the constructed reference picture.
