Abstract: Methods and apparatus for reducing electromagnetic interference resultant from data transmission over a high-speed audio/visual interface. In one embodiment, an HDMI source device is disclosed. The HDMI source device includes a wireless interface and an HDMI interface coupled with an active filter circuit topology. The active filter circuit topology includes a pair of differential signal lanes; a passive filter circuit disposed within each of the pair of differential signal lanes; a plurality of active filter circuits, with at least a first active filter circuit disposed on one side of the passive filter circuit and at least a second active filter circuit disposed on the other side of the passive filter circuit; a plurality of diodes, with each of the plurality of active filter circuits coupled with a respective diode; and switching logic coupled with the plurality of diodes. Methods of operating the HDMI source device and HDMI systems are also disclosed.

Abstract: Techniques are disclosed for automated detection and notification of interconnect errors or failure. An interconnect is tested via passive or active means. Error data associated with data transferred via the interconnect is measured and analyzed to generate error statistics. Error statistics are then used to determine an error rate of the interconnect and an alert is generated if the error rate exceeds a threshold. Alerts are displayed to users for troubleshooting and/or for indication that the interconnect should be replaced.
