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) 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.

摘要： 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.

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 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.

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 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.
摘要翻译：高速视频电缆根据高分辨率多媒体接口（HDMI）或DisplayPort标准传送信号，并包括原始电缆和升压装置。原始电缆包括特性电缆阻抗低于标准中所暗示的阻抗的同轴线。在发射端通过安装在第一电缆连接器中的串联电阻器观察到正确的阻抗。所产生的信号损失由安装在电缆另一端的连接器中的升压装置构成。降低电缆阻抗可减小同轴屏蔽的直径，从而产生较薄的电缆，或相反地增加导线的线规，以避免非常薄的同轴电缆的成本和脆性更高，从而可以更简单和更低成本地生产和组装电缆。使用屏蔽双绞线（STP）代替同轴线路时，可获得类似的优点。
