Patent ID: 10938516

Abstract:
Systems and methods for packet re-transmission via a bi-directional wired interface between two devices are provided. A transmitter of a first device transmits one or more first transmit data packets to a second device over the bi-directional wired interface. Concurrently with the transmission of the one or more first transmit data packets, the first device receives, over the bi-directional wired interface, one or more second received data packets from the second device. A packet integrity monitor of the first device monitors whether one or more received data packets of the second received data packets is corrupted at the physical layer of the first device. In response to detecting that one or more received data packets of the second received data packets is corrupted, the first device re-transmits one or more transmit data packets of the first transmit data packets that was previously transmitted over the bi-directional wired interface.
