  • Patent number: 7908634
    Abstract: A High-Definition Multimedia Interface (HDMI) cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. High-frequency loss and differential skew within a differential signal may be compensated by analog circuits embedded in the cable. These embedded circuits are tuned at production for best performance by observing the quality of the recovered analog signal. The embedded circuits are powered by a combination of power sources, both carried within the cable, and harvested from the high-speed signals themselves.

  • Patent number: 7873980
    Abstract: A High Definition Multimedia Interface (HDMI) cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. A Mobile High-Definition Link (MHL) cable carries high speed data which are multiplexed to achieve smaller connectors with fewer pins. A MHL-to-HDMI cable is proposed which includes an embedded MHL to HDMI format conversion device for demultiplexing the received MHL-formatted signal and outputting an HDMI-formatted signal. The embedded device is powered by a combination of power sources, the power being harvested from the high-speed HDMI signals themselves.

  • Publication number: 20100258333
    Abstract: A high speed cable to carry signals according to the High-Definition Multimedia Interface and Universal Serial Bus 3.0 standards is disclosed. The cable includes a raw cable, having a conductive braid, a ground wire, signal lines; and two terminating assemblies at each end of the raw cable. The conductive braid is coupled to the ground wire in each of the terminating assemblies through a respective inductor to reduce the ground resistance of the cable, thus permitting construction of a thinner, lighter, and more flexible cable.

  • Patent number: 7809085
    Abstract: A high-definition multimedia interface (HDMI) receiver recovers high speed encoded data which are transmitted differentially over data channels of a lossy cable, along with a clock. Inter symbol interference, high-frequency loss, skew between the clock and data channels, and differential skew within a differential signal are compensated by analog circuits which are automatically tuned for best performance by observing the quality of the recovered analog signal. Oversampling is used to provide a 24-bit digital representation of the analog signal for determining the quality of the signal.

  • Publication number: 20100020179
    Abstract: A High Definition Multi-Media Interface (HDMI) cable may exhibit frequency dependent signal attenuation, inter symbol interference, and inter-pair skew. A boost device integrated with the cable can compensate for such impairments of the cable. A self calibrating cable with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel. Additional embodiments provide for a selected replica boost device and a distinct pattern generator device in the calibration fixture.
