Video optimized media streamer having communication nodes received digital data from storage node and transmitted said data to adapters for generating isochronous digital data streams

摘要

A media streamer (10) includes at least one control node (18); at least one storage node (16, 17) for storing a digital representation of a video presentation; and a plurality of communication nodes (14) each having an input port that is switchably coupled under the direction of the control node to an output of the at least one storage node for receiving a digital representation of a video presentation therefrom. Each of the plurality of communication nodes further includes at least one output port for coupling to a first end of a communications bus (210). Individual ones of the communication nodes output a digital representation of a video presentation as a sequence of data bursts to the first end of the communications bus. The media streamer further includes an adapter (15), coupled to a second end of the communications bus, for receiving the sequence of data bursts and for converting the received sequence of data bursts to a substantially isochronous data stream that represents a video presentation.
