Abstract
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.
