The method of the present invention includes loading a selected set of preset parameters into a source device and a sink device of the DisplayPort device of an embedded system. Link training is then performed between the source device and the sink device utilizing the first set of preset parameter and the link status (bit lock, symbol lock and inter-lane alignment) of the DisplayPort device is then read. If the link status indicates that the link training is successful, a link is established between the source device and the sink device, or if the link status indicates that the link training is unsuccessful, a different set of preset parameters is loaded and link training is then performed again. The steps of loading, performing and reading are repeated with each of the plurality of sets of preset parameters until the link status indicates that the link training is successful.

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.

The invention provides a system of components, methods for assembly, and a hand tool, for adding a HDMI (i.e. All HDMI Types: A, B, C, D, and E), DiiVA, DisplayPort, Mini DisplayPort, DVI, and USB (i.e. all USB Types, A, B, mini-A, mini-B, micro-A, and micro-B) connector to standard and modified ribbon cables for field termination or factory installation. Features of the connector system including the locking top shell, bottom shell, single shell, wire holders and the connector core all make possible and efficient the addition of a solderless male connector. The invention also provides a locking plug which can mate with female connectors with great retaining force. Features of the modified ribbon type cable facilitate threading of the wire holders significantly improving the time it takes to assemble a male connector on the cable. The hand tool disclosed is designed to accomplish all steps of assembly for field termination.

The invention relates to a method for switching a multimedia source and multimedia sink from an operating mode to a standby mode, and a method for switching a multimedia source and multimedia sink from a standby mode to an operating mode. When the consumer device comprises two distributed boxes, such as a TV in which the display (multimedia sink) is separated from the processing unit (multimedia source) via a cable, then meeting the green rules for standby power becomes more complicated. The power consumption of processing unit and display unit should be minimal in standby mode. The methods of the invention provide for synchronizing the power states of both units, such that only the relevant parts remain active. The method is applicable on configurations where a DisplayPort link is used between a multimedia source, such as a set-top box, and a multimedia sink, such as a display. The invention provides a reduction in overall power consumption, while still complying with the Display-Port configuration and operation standard. In an embodiment of the invention, the source and sink are configured to allow communication of standby and wake-up requests/commands when the transmitter and receiver for the auxiliary channel are powered down. The invention also provides embodiments where the switching to and from standby of the source is triggered by user

The invention disclosed a data transmission system, comprising a first conversion module provided on the host side, used for converting USB data into data in format which may be transmitted by a data transmission module and for converting data in format which may be transmitted by the data transmission module into USB data the data transmission module provided between the host and the monitor, used for data intercommunication between the host and the monitor, and a second conversion module provided on the monitor side, used for converting USB data into data in format which may be transmitted by the data transmission module and for converting data in format which may be transmitted by the data transmission module into USB data. Wherein, the data transmission module is a DisplayPort auxiliary channel (DisplayPort AUX CH). With the invention, the connection of the personal computer host and the monitor may be realized by using only one DisplayPort cable, thereby USB interfaces may be integrated on the monitor. The manner may reduce the complexity and cost of the computer system, and may enhance the user experience.

A DisplayPort socket includes a first composite element and a second composite element. The first composite element includes a first insulating body partially and tightly covering plural terminals so that the terminals are exposed on a plate of the first insulating body and form plural conduction zones. The second composite element includes a second insulating body partially and tightly covering plural terminals so that the terminals are exposed on a plate of the second insulating body and form plural conduction zones. The plates of the first and second composite elements are stacked flat on each other to form a coupling plate for coupling buttingly with a DisplayPort connector. By integrating the first and second insulating bodies with their corresponding terminals to form the first and second composite elements and then assembling the first and second composite elements together, the terminals are securely positioned, thus increasing the reliability of the socket.

An integrated controller for an integrated display and touch panel and its associated method provide (a) a DisplayPort or embedded DisplayPort interface for communicating control and data signals for both display and touch functions between a host system and the integrated controller, wherein the touch control and data signals are communicated over an auxiliary channel of the DisplayPort or embedded DisplayPort interface; (b) a display panel interface for communicating display data and control signals between the integrated controller and a display monitor; (c) a touch panel interface for communicating touch data and control signals between the integrated controller and a touch panel; and (d) a control circuit which processes the display and touch control and data signals of the DisplayPort or embedded DisplayPort interface, the display data and control signals of the display panel interface and the touch data and control signals of the touch panel interface.

An error correction circuit and method applicable to a DisplayPort receiver is disclosed. While decoding errors occur at a decoding stage, the invention actively adjusts settings of a physical layer by using an ANSI10B/8B decoder and performs data recovery by using a correcting unit that improves the reliability of input data.

Various exemplary embodiments relate to a function selector device in a system using a DisplayPort protocol over a universal serial bus (USB) mechanical interface, including: a first port configured to transmit/receive a USB SSTX signal; a second port configured to transmit/receive a USB SSRX signal; a third port configured to transmit/receive a DisplayPort lane signal; a fourth port configured to transmit/receive a DisplayPort AUX signal; a fifth port configured to transmit/receive a DisplayPort HPD signal; a sixth port configured to connect to SSTX pins of a USB 3.0 receptacle; and a seventh port configured to connect to SSRX pins of a USB 3.0 receptacle.

A dual-purpose socket has a body, pin base and a pin set. The body has a front side, a chamber defined in the body and at least one opening. The at least one opening is formed through the front side, communicates with the chamber and allows an HDMI or Displayport plug to be inserted into the chamber. The pin base is mounted in the chamber and corresponds to HDMI and Displayport plugs. The pin set is mounted on the pin base and comprises a detecting pin. When the HDMI or Displayport plug is inserted into the chamber of the body, the detecting pin will respectively not touch or touch a pin of the HDMI or Displayport plug. Since HDMI and Displayport plugs can be used, the dual-purpose socket improves convenience and cost for electronic device consumers and manufacturers.
