Abstract

A media streamer includes at least one storage node for storing a digital representation of a video presentation. The video presentation requires a time T to present in its entirety, and is stored as a plurality of N data blocks, each data block storing data corresponding approximately to a T/N period of the video presentation.
The media streamer further includes a plurality of communication nodes each having at least one input port and at least one output port; a circuit switch connectedbetween the at least one storage node and input ports of the plurality of communication nodes, the circuit switch selectively coupling one or more of the input ports to the at least one storage node to enable the digital representation stored thereat to appear at one or more of the output ports; and at least one control node coupled at least to the plurality of communication nodes and to the at least onestorage node for enabling any one of the N blocks to appear at any output port of any of the plurality of communication nodes.
