1. A wired communication method for a video source device comprising an Ethernet MAC and an asymmetric multi-rate Ethernet PHY, the wired communication method comprising:

  • transmitting data from the asymmetric multi-rate Ethernet PHY over a twisted-pair wire of an Ethernet cable at a first downstream data rate;

    receiving data at the asymmetric multi-rate Ethernet PHY over the twisted pair wire at a first upstream data rate, the first downstream data rate being larger than the first upstream data rate; and

    reducing the first downstream data rate to a second downstream data rate that is less than the first downstream data rate while performing a signal processing operation on the data transmitted at the first downstream data rate to at least one of extending a range of the Ethernet cable and increasing an insertion loss of the Ethernet cable.
