摘要： 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.

摘要： 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 to 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. 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.

摘要： 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.

摘要： 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.

摘要： 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.
