Publication number: 20120012387Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and a boost device. The raw cable includes coaxial lines of a characteristic cable impedance lower than the impedance implied in the standards. The correct impedance is observed at the sending end by series resistors mounted in the first cable connector. The resultant loss of signal is made up with the boost device mounted in the connector at the other end of the cable. Reducing the cable impedance reduces the diameter of the coaxial shields to result a thinner cable, or conversely increases the wire gauge of the conductors to avoid the higher cost and fragility of very thin coax wires, thus permitting simpler and lower cost production and assembly of the cable. Similar advantages are obtained when Shielded Twisted Pairs (STP) are used instead of coaxial lines.Type: ApplicationFiled: July 13, 2010Publication date: January 19, 2012Inventors: John Martin Horan, Gerald Donal Murphy, David William Mc Gowan, John Anthony Keane

Patent number: 8073647Abstract: 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.Type: GrantFiled: July 30, 2009Date of Patent: December 6, 2011Assignee: Redmere Technology Ltd.Inventors: John Martin Horan, John Anthony Keane, Gerard David Guthrie

Patent number: 8058918Abstract: An 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.Type: GrantFiled: July 18, 2007Date of Patent: November 15, 2011Assignee: Redmere Technology Ltd.Inventors: Aidan Gerard Keady, John Anthony Keane, Judith Ann Rea, Benjamin Griffin, John Martin Horan

Patent number: 8006277Abstract: A method for providing power to a boost device in a high-speed cable connected between a transmitting data source device and a receiving data sink device is described. The method comprises receiving differential data signals from the data source device in a differential input circuit of the boost device; boosting at least one of the received differential data signals into a boosted differential data signal; transmitting the boosted differential data signal from a differential output circuit of the boost device to the receiving data sink device; and obtaining power to operate at least some of the circuitry of the boost device from the data sink device through its connection with the differential output circuit, for example, providing at least some of the power to operate the processing block. A corresponding high-speed cable is also described.Type: GrantFiled: March 2, 2011Date of Patent: August 23, 2011Assignee: Redmere Technology Ltd.Inventors: Aidan Gerard Keady, John Anthony Keane, Judith Ann Rea, Benjamin Griffin, John Martin Horan
