An apparatus and a method for data streaming, as well as a combination, of an apparatus for data streaming and a plurality of user devices, are presented. The apparatus is adapted to receive a plurality of streaming requests, including mode requests, from a plurality of user devices, the apparatus comprising a memory unit adapted to store media data in the form of a plurality of payload data sets, a state device adapted to set a mode in accordance with each one of the mode requests, and a streaming unit adapted to stream the payload data sets in accordance with the set modes. The streaming unit is adapted to receive from the memory unit a plurality of control data sub-sets, each comprising at least two edit portions, each comprising data corresponding to an address in the memory unit.

Method and an apparatus for data streaming

The present invention relates to methods for changing the bandwidth of a circuit switched channel in a time division multiplexed network, wherein said channel comprises a set of time slots within each recurring frame of a bitstream between a first node and a second node. According to the invention one or more additional time slots within each recurring frame of said bitstream are reserved, including using, during a period of time, only said set of time slots for transmitting payload data pertaining to said channel while providing, during said period of time, information indicating that said one or more additional time slots are currently not used for transferring payload data. After said period of time, said set of time slots is used as well as said one or more additional time slots on said bitstream for transmitting payload data pertaining to said channel.

Methods for changing the bandwidth of a circuit switched channel

A method and an apparatus for switching data between a set of input bitstreams and a set of output bitstreams in a circuit switched time division multiplexed network is presented. Each bitstream is divided into recurring frames and each frame is divided into time slots. Each one of the input bitstreams is received, and frames of time slot data thereof are temporarily stored in a set of memories. Each of the memories is used for storing frames of a respective bitstream of the input bitstreams. For each frame of each one of the output bitstreams, and sequentially in accordance with the order that the time slot data are to be transmitted in the respective output frame, time slot data is selectively read from frames presently temporarily stored in the set of memories, and is then transmitted into allocated time slots of the output bitstreams.
