  • Patent number: 9318241
    Abstract: A high speed data cable carries high-speed and auxiliary signals, and includes a raw cable. The raw cable includes coaxial lines which are covered by an outer conductive shield. High-speed signals are carried on the inner conductors of a pair of coaxial lines. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, and/or the outer conductive shield.
    Type: Grant

  • Patent number: 9076575
    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 is exclusively constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded wires or their shields. The high speed signals are carried on the shielded wires to the boost device where any common mode noise induced by the signals on the shields is removed. Some auxiliary signals including power are carried on ungrounded shields.

  • Patent number: 9040823
    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.

  • Publication number: 20140241440
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and may include a boost device. The raw cable includes coaxial lines which are covered by an outer metallic braid. Each of four high speed video signals is carried on the inner conductors of a pair of coaxial lines. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, as well as the braid of the cable, thus permitting fourteen HDMI signals to be carried in a cable comprising only eight coaxial lines, resulting in a simpler and lower cost production and assembly of the cable.

  • Patent number: 8674226
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and a boost device. Each of four high speed video signals is carried on the inner conductors of a pair of coaxial lines in the raw cable. The boost device receives only one of the polarities of one of the high speed video signals, and generates a differential signal therefrom. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines.

  • Patent number: 8674223
    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 may include a boost device. The raw cable includes coaxial lines of a characteristic cable impedance higher than the impedance implied in the standards. The correct impedance is observed at the sending end by shunt resistors mounted in the first cable connector. The resultant loss of signal may be made up with the boost device mounted in the connector at the other end of the cable in the case of a long cable.

  • Publication number: 20120012359
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable. The raw cable is constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded conductors or their shields. Some auxiliary signals including power are carried on ungrounded shields. This achieves a reduction in the number of wires in the cable leading to a thinner, lighter, and less costly HDMI or DisplayPort Cable. The use of a uniform technology, either STP or coax, also permits simpler and lower cost production and assembly of the cable.

  • Publication number: 20120012387
    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. 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.

  • Publication number: 20120012358
    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 may include a boost device. The raw cable includes coaxial lines of a characteristic cable impedance higher than the impedance implied in the standards. The correct impedance is observed at the sending end by shunt resistors mounted in the first cable connector. The resultant loss of signal may be made up with the boost device mounted in the connector at the other end of the cable in the case of a long cable. Increasing the cable impedance reduces the inherent loss of the raw cable thus permitting the use of low cost material such as tinned wires. Similar advantages are obtained regardless whether Shielded Twisted Pairs (STP) or coaxial lines are used.
