Abstract: A method includes receiving, via an input service running on a server, a transcoding request from a client, the transcoding request requesting a segment of digital content, the transcoding request containing a start time of the segment and a duration of the segment; requesting, via the input service, the segment from a source based on the transcoding request; receiving, via the input service, the segment and metadata from the source based on the requesting, the metadata being related to the start time and the duration; transcoding, via the input service, the segment based on the metadata in the transcoder service; and sending, via the input service, the segment from the transcoder service to the client based on the transcoding.

Abstract: Targeted messaging, for example advertisements, may be provided to a user terminal connectable to a service node in a communications network, said network comprising a library node connected to the service node and comprising messages, such as advertisements, in different formats for different access types, by the following steps: requesting the delivery of at least one message from the library node to the service node for distribution to the user terminal, while specifying in the request the access type used by the user terminal, and providing from the library node to the service node the appropriate version of the at least one message in dependence of the access type used by the user terminal. One or more parameters, such as demographic data, may be specified for how to select a message from the library node.

Abstract: The reliability of a data flow between a server and a client in a data communications network is increased. An application in a user terminal is arranged to receive information from a server, such as a push server or a streaming server, in the network. A user who should have an active connection to the server is monitored to determine if the user currently has such a connection. An appropriate action is taken if this is not the case. The user's connection to the data communications network is monitored. If connected to the data communications network, the user should also have an active connection to said server.

Abstract: Targeted messaging, for example advertisements, may be provided to an end user terminal connectable to a service node in a communications network, said network comprising a library node connected to the service node and comprising messages, such as advertisements, in different formats adapted to different access types, by the following steps: requesting the delivery of at least one message from the library node to the service node for distribution to the terminal, while specifying in the request the access type used by the terminal, and providing from the library node to the service node the appropriate version of the at least one message in dependence of the access type used by the terminal. One or more parameter, such as demographic data, may be specified for how to select a message from the library node.
