[Problem] To provide a communication device capable of properly identifying a communication partner device. [Solution to Problem] A communication device 1 includes: a connection detector 3 which detects that the communication device is connected to a communication partner device, using a specific communication interface; a specific information acquisition unit 4 which acquires specific information including at least one of specific time information and a specific message, when the connection with the communication partner device is detected by the connection detector; a packet generator 5 which generates a packet including the specific information; and a broadcaster 6 which broadcasts the packet through a network.

A Display-Port optical connector including a host-side auxiliary interface and a display-side auxiliary interface is provided. The host-side auxiliary interface stores extended display identification data (EDID) and display port configuration data (DPCD) of the display device via communication with an external device, and, when the host-side auxiliary interface is connected to the auxiliary signal terminals of the host device, the host-side auxiliary interface instead of the display device provides the EDID and the DPCD to the host device. When the display-side auxiliary interface is connected to the auxiliary signal terminals of the display device, the display-side auxiliary interface instead of the host device reads the EDID and the DPCD from the display device and stores the read-out EDID and DPCD, and controls an operation of the display-side main interface while performing DPCD communication with the display device.

A drive control method, assembly, and a display device. The method is applied to a timer controller. The method comprises: generating a point-to-point configuration instruction that comprises n configuration data where n≥2; sending the point-to-point configuration instruction to a first source driver chip through a first signal line, the first source driver chip being any one of a plurality of source driver chips; and receiving a configuration response instruction sent by the first source driver chip according to the point-to-point configuration instruction through the first signal line, the configuration response instruction comprising configuration response data for each of the n configuration data.

A configuration information setting method including: receiving a user-triggered information setting indication; generating, according to the information setting indication, an information setting instruction including setting indication data, the setting indication data configured to instruct the source driver to set configuration information of the source driver according to the setting indication data; and transmitting the information setting instruction to the source driver via the first signal line.

A communications cable is disclosed. The cable includes a first circuit configured to receive electrical data signals from a data source via an input connector, and convert the electrical data signals into optical signals for transmission by way of one or more optical fibers. The cable includes a second circuit configured to convert the optical signals received via the one or more optical fibers back to electrical data signals for providing to a data sink via an output connector. The cable includes a third circuit for applying pre- and post-signal conditioning to bi-directional control data for transmission to and received from the data sink via wires. The cable includes a fourth circuit for applying pre- and post-signal conditioning to bi-directional control data for transmission to and received from the data source via wires. The pre- and post-signal conditioning compensate for capacitance and/or resistance effects on the signals introduced by the wires.

Aspects relate to transmission of metadata from a source to a sink device, and optionally through one or more intermediaries. A source device encodes metadata into what would have been a blanking area of a field to be transmitted, according to a current video format. The source device encodes a timing for an active video data signal that is modified from a timing that would be used only for transmission of video data at a current resolution. A separate indicator from the source, or a negotiation between source and sink allows the sink to determine what part of the data indicated as being active video data is metadata, and to use that metadata for controlling aspects of the video display, and to use other parts of the received video data as video data for display. A sink can signal supported capabilities to a source.

An image output apparatus according to the present invention includes: communicating units; an acquiring unit configured to acquire, for each of the communicating unit connected to an image display apparatus, correspondence information; a setting unit configured to set, for each of the communicating unit, an output mode; and an outputting unit configured to output, for each of the communicating unit, image data based on an output mode set with respect to the communicating unit, wherein the setting unit automatically sets a first output mode with respect to a communicating unit for which the correspondence information has been acquired.

The present disclosure relates to a data driving device, a method, and a system for driving a display device, and more particularly, it relates to a data driving device, a method, and a system to provide an internal operation state of the data driving device in response to a request of the data processing device when the display device is driven.

An image display device includes: a signal input unit to which a first signal or a second signal is supplied using a signal cable in accordance with prescribed setting information, the signal cable having a plurality of transmission lines of prescribed transmission characteristics; a transmission line control unit configured to change a destination to which a signal is supplied using the plurality of transmission lines, in accordance with a transmission line setting for setting at least a portion of the plurality of transmission lines as transmission lines which transmit the first signal; an image control unit configured to generate an image signal from the first signal supplied using the transmission lines in accordance with a transmission format setting for designating a format for transmitting the first signal using the transmission lines; and a setting control unit configured to change the transmission line setting and the transmission format setting.
