Method and system for enabling video communication via ethernet utilizing asymmetrical physical layer operations
First Claim
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.

Abstract
Signals may be communicated between a video source and a video rendering device via and asymmetrical multi-rate Ethernet physical layer (PHY). The asymmetric multi-rate PHY may support multiple rates. The asymmetrical multi-rate Ethernet PHY may handle compressed and/or uncompressed, encrypted and/or unencrypted video signals and may handle audio/video bridging. One or more of the communicated signals may be modified by an echo cancellation operation, a near end cross talk (NEXT) cancellation operation, equalization, a far end cross talk (FEXT) cancellation operation and/or a forward error correction (FEC) operation. An aggregate communication rate may be evenly or unevenly distributed among one or more links coupling the video signal source to the video rendering device. A plurality of links coupling the video signal source to said video rendering device may also be aggregated.
