摘要： In some embodiments, a system for providing DisplayPort communication over an extension medium is provided. The system comprises an upstream facing port device (UFP device) and a downstream facing port device (DFP device). The UFP device is configured to conduct link training with a DisplayPort source device using first DisplayPort configuration data (DPCD). The DFP device is configured to conduct link training with the DisplayPort sink device using second DPCD different from the first DPCD. The UFP device is configured to extract video data from DisplayPort data received from the DisplayPort source device and transmit the video data to the DFP device. The DFP device is configured to receive the video data, generate DisplayPort data as specified by the second DPCD, and transmit the generated DisplayPort data to the DisplayPort sink device as specified by the second DPCD.

摘要： Extension devices such as upstream facing port devices (UFP devices) and downstream facing port devices (DFP devices) connect via an extension medium. When a UFP device and a DFP device pair with each other, DisplayPort video and/or audio information from a DisplayPort source device can be presented by a DisplayPort sink device, which are coupled to the UFP device and DFP device, respectively. In some embodiments, the DFP device may train a DisplayPort link to the DisplayPort sink device regardless of whether it is receiving actual data from a UFP device, and may provide placeholder data to the DisplayPort sink device in order to keep the link active. The DFP device may then replace the placeholder data with the actual data from the UFP device, once received, and may thereby seamlessly switch the DisplayPort sink device from presenting placeholder data to presenting data from the DisplayPort source device.

摘要： Embodiments of the present disclosure provide systems and/or methods for managing power distribution over a USB topology. In some embodiments, a host device is coupled to an upstream facing port device (UFP device) via a USB compliant connection, and a USB device is coupled to a downstream facing port device (DFP device) via a USB compliant connection. The UFP device and DFP device are connected via a non-USB compliant extension medium. In various embodiments, the UFP device and DFP device may be individually powered by different types of sources (such as external power sources, power distributed over the extension medium, batteries, USB bus power, and/or the like). The UFP device and DFP device cooperate to provide USB power distribution functionality throughout the USB topology despite the presence of the non-USB compliant extension medium.

摘要： In some embodiments, the present disclosure provides techniques for reducing an amount of bandwidth used for the communication of DisplayPort information via a USB Type-C receptacle. In some embodiments, this reduction in bandwidth allows for the concurrent exchange of USB 2.0 information, SuperSpeed information, and four lanes of DisplayPort information via a single USB Type-C receptacle. In some embodiments, this may be accomplished in part by processing the information from the four DisplayPort lanes to be transmittable via two differential pairs of the USB Type-C connection, thereby providing four lanes of DisplayPort communication over the USB Type-C connection concurrently with SuperSpeed information. In some embodiments, the reduction in bandwidth of the DisplayPort information may be used for other purposes, such as transmitting high bandwidth DisplayPort information over a cable or connector of a low quality that would otherwise not support such an exchange.

摘要： In some embodiments, an upstream facing port device (UFP device) is connected to a DisplayPort source device via a connection that complies with the DisplayPort specifications. A downstream facing port device (DFP device) is connected to a DisplayPort sink device via a connection that complies with the DisplayPort specifications. The UFP device and the DFP device are connected via an extension medium to allow the DisplayPort source device to provide video and/or audio for presentation by the DisplayPort sink device. In some embodiments, the UFP device and/or the DFP device may be configured to provide video extracted from the DisplayPort communication to an external video processing device for processing before and/or after transmission over the extension medium.

摘要： Devices, systems, and methods for selectively pairing an upstream facing USB port device (UFP device) and a downstream facing USB port device (DFP device) over a network are disclosed. A controller device sends pairing commands to a selected UFP device and a selected DFP device, which then establish a connection with each other over a network. The controller device may subsequently cause the UFP device and/or the DFP device to remove the existing pairing and to instead pair with a different UFP device or DFP device. A pairing between a UFP device and a DFP device allows a host device coupled to the UFP device and a USB device coupled to the DFP device to communicate via a USB-compatible protocol.

摘要： A system and method for communicating DisplayPort information is provided. The system includes: a local unit comprising a local controller operable to produce a request packet in response to a DisplayPort request received by the local unit from a DisplayPort source unit and to transmit the request packet to a remote unit of the system via a first simplex channel of a dual simplex communications link; and the remote unit comprising a remote controller operable to produce a reply packet in response to a DisplayPort reply received by the remote unit from a DisplayPort sink unit and to transmit the reply packet to the local unit via a second simplex channel of the communications link. The system allows distances between the source and sink greater than otherwise possible under the DisplayPort specification, and can communicate DisplayPort and non-DisplayPort signals via a variety of types of communications links.

摘要： Devices and methods for providing SuperSpeed USB connections across an extension medium are provided. An upstream facing port device (UFP device) and a downstream facing port device (DFP device) are connected by an extension medium, and communicate via an extension protocol. The UFP device and the DFP device include switchable receiver termination circuitry. The receiver termination at the UFP device is enabled upon determining that a USB device coupled to the DFP device supports SuperSpeed communication, and the receiver termination at the DFP device is enabled upon determining that a host device coupled to the UFP device supports SuperSpeed communication.
