There is provided a controller that prevents any external power source from supplying its power if a host device and a monitoring device are not connected exactly through optical extension cables based on DVI standard, and that prevents a sequence for digital transmission of a video signal from being started if the external power source remains off. Only when the proper (DDC+5V) signal is generated from the host device and the external power source has been turned on, the (DDC+5V) signal is transmitted to the monitoring device, and when it is detected in the monitoring device that the transmitted signal is the proper (DDC+5V) signal, the (DDC+5V) signal is transmitted to the monitoring device. Also, when it is detected that the proper HPD signal has been generated from the monitoring device, the power of the external power source is supplied to attached circuits of the host device and the monitoring device, and if the HPD signal transmitted to the host device is the proper signal, the HPD signal is transmitted from the monitoring device to the host device.
Description
technical field [0001] The present invention relates to a timing control device for a master device and a monitoring device connected to each other according to DVI (Digital Visual Interface; digital display interface) specifications. When connecting, confirm whether the two devices are connected normally through the optical extension cable, and at the same time confirm whether the power has been supplied from the external power supply to the control device of the main device and the auxiliary circuit of the monitoring device. Background technique [0002] In recent years, the DVI standard is used when digitally transmitting video signals from a host device such as a computer to a monitor device such as a device including a liquid crystal display (LCD). In the DVI specification, a digital transmission method such as T.M.D.S. is adopted. In simple terms, a T.M.D.S. transmitter and a DVI connector are installed in the main device, a T.M.D.S. The controller and the DVI connect...
