Multimode physical layer module for supporting delivery of high-speed data services in home multimedia networks

摘要

A multimode physical (MMP) layer circuit for physical (PHY) layer handling of signals transported over a high-definition multimedia interface (HDMI) cable in a home multimedia network, wherein the signals are compliant with at least two different PHY layer modes. The MMP layer circuits comprises a plurality of PHY transceivers respectively coupled to a plurality of TP channels of the HDMI cable through a HDMI connector, wherein each PHY transceiver of the plurality of PHY transceivers handles signals transported over its respective TP channel according to a PHY layer mode of the transported signals; and a controller is coupled to the HDMI connector and to each of the plurality of PHY transceivers, the controller recognizes the PHY layer mode of signals transported over each of the plurality of TP channels and sets each of the plurality of PHY transceivers according to the recognized PHY layer mode.
