Abstract:
1. A method of transmitting flow control and retransmission information comprising: a. configuring a transmitting plug on a receiving device for transmitting an isochronous back channel packet over an isochronous channel via the transmitting plug to a transmitting device; b. determining flow control and retransmission information based on the status of a received isochronous data packet at the receiving device, wherein the received isochronous data packet is one of a stream of isochronous data packets transmitted from the transmitting device to the receiving device, wherein the stream of isochronous data packets is transmitted in non real-time; c. packetizing flow control and retransmission information within the isochronous back channel packet; and d. transmitting the isochronous back channel packet from the receiving device over the isochronous back channel via the transmitting plug, wherein the back channel packet includes a control instruction that instructs the transmitting device to reset transmission of the stream of isochronous data packets starting from a specified packet within the stream of isochronous data packets, such that the specified packet and packets after the specified packet within the stream of isochronous data packets are transmitted.
