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.
