A method for optimizing the performance of an active HDMI cable. An active cable compensator is provided within the HDMI cable itself. 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. The programming is preferably performed with the cable installed between the actual source and actual sink it will be connecting. The HDMI cable includes an internal controller that governs the equalizers and other active functions. A memory is connected to this controller so that settings may be retained even when power is lost.

Programmable HDMI cable and method including external programmer

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.

In an S-video signal processor, the luminance signal is amplified and adjusted over selected frequency ranges using a parallel signal for shaping the S-video signal response and permitting the S-video signal to be transmitted over exceptionally long transmission lines while providing a quality picture. In separate channels, chrominance and luminance signals are amplified and impedance matched. A luminance band pass filter permits manual adjustments to a lower range of video signal frequencies and thus changes to white level picture information. One version of the S-video signal processor includes a positive feedback network which permits user adjustments in an upper video signal frequency range having picture super detail information for providing a picture of high resolution and thus pleasing to the user. In a second version a compensation amplifier is used to alter the frequency response of the luminance signal. A clear picture, brighter and sharper, rather than simply a brighter picture is available whether transmitted over a few or few hundred feet from a video source to a video monitor.
