  • Patent number: 9955112
    Abstract: Provided is a digital-image transmission apparatus including a transmitting unit connected to a host device and a receiving unit connected to a display device. The transmitting unit includes a host-side additional-communication control unit that controls additional communication for digital image transmission. The host-side additional-5 communication control unit performs communication with an external device to diagnose an operation state of the transmitting unit, transmit a diagnosis result to the external device, and control an operation of the transmitting unit.

  • Publication number: 20170242201
    Abstract: 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.
