  • Video optimized media streamer user interface employing non-blocking switching to achieve isochronous data transfers
    Patent number: 5805821
    Abstract: A media streamer (10) includes at least one control node (18); a user interface (64, 65, 66) having an output coupled to the at least one control node; at least one storage node (16, 17) for storing a digital representation of at least one video presentation; and a plurality of communication nodes (14) each having an input port for receiving a digital representation of at least one video presentation therefrom. 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 stores data corresponding to a T/N period of the video presentation. Each communication nodes further has a plurality of output ports for outputting a digital representation. A circuit switch (12) is connected between the at least one storage node and the input ports of communication nodes for coupling one or more input ports to the at least one storage node.

  • Video data streamer having scheduler for scheduling read request for individual data buffers associated with output ports of communication node to one storage node
    Patent number: 5761417
    Abstract: A media streamer (10) includes at least one storage node (16, 17) comprising mass storage for storing a digital representation of at least one video presentation; and a plurality of communication nodes (14) each having at least one input port that is coupled 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 a plurality of output ports, individual ones of the plurality of output ports being operable for transmitting a digital representation as a data stream to a consumer of the digital representation. Individual ones of the output ports also have an associated data buffer for buffering a portion of a digital representation prior to a transmission of the digital representation.

  • Video data streamer for simultaneously conveying same one or different ones of data blocks stored in storage node to each of plurality of communication nodes
    Patent number: 5712976
    Abstract: A media streamer (10) includes at least one storage node (16) including mass storage for storing a digital representation of at least one video presentation. The mass storage is comprised of a plurality of mass storage units. The at least one video presentation requires a time T to present in its entirety, and is stored as a plurality of N data blocks. Each data block stores data corresponding to approximately a T/N period of the video presentation. The media streamer further includes a plurality of communication nodes (14) each having at least one input port that is coupled 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 a plurality of output ports individual ones of which transmit a digital representation as a data stream to a consumer of the digital representation.

  • Media streamer with control node enabling same isochronous streams to appear simultaneously at output ports or different streams to appear simultaneously at output ports
    Patent number: 5668948
    Abstract: A media streamer (10) includes at least one storage node (16, 17) 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.
