Patent number: 8520776Abstract: 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.Type: GrantFiled: July 30, 2009Date of Patent: August 27, 2013Inventors: Judith Ann Rea, Aidan Gerard Keady, John Anthony Keane, John Martin Horan

Patent number: 8295296Abstract: 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: October 23, 2012Assignee: 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
