Abstract
A method for optimizing the performance of an active HDMI cable. An active cable compensator is provided within the HDMI cable itself. This device applies an individually-adjusted equalizer to each of the TMDS video data lines. A non-equalizing amplifier is applied to the two TMDS clock lines. An accelerator is applied to the IC data bus. The parameters controlling each of the active components (such as parameters setting gain and frequency distribution) within an individual HDMI cable are set through a programming process. In that process, a calibration source sends known signals through the cable to a programming unit. A programming unit analyzes the signals through the cable and sends commands to the active cable compensator in the cable. The commands adjust the parameters in order to optimize the performance of the individual cable.
