Patent ID: 7865610

Claim:
A method of transmitting an Exporter-to-Exgine (E2X) packet of an E2X data stream from an Exporter over a studio-to-transmitter link (STL) to a plurality of exciter engines (Exgines), the method comprising: receiving at the exporter an E2X packet for transmitting to the plurality of Exgines; segmenting the received E2X packet into fragment packets of a maximum size; placing the segmented fragment packets onto a main queue; transmitting a clock packet from the Exporter to the plurality of Exgines over the STL; retrieving a maximum number of retransmission packets from a retransmit packet buffer; placing the retrieved retransmission packets onto a FIFO transmit queue; placing a plurality of segmented fragment packets from the main queue onto the FIFO transmit queue; transmitting packets from the FIFO transmit queue of the Exporter to the plurality of Exgines over the STL; receiving a first re-transmit request from a first Exgine of the plurality of Exgines identifying a transmitted fragment packet; placing the fragment packet identified for retransmission onto the retransmit packet buffer; receiving a second re-transmit request from a second Exgine of the plurality of Exgines identifying the transmitted fragment packet; and ignoring the second re-transmit request when the second re-transmit request is received within a time window of receiving the first re-transmit request.
