dvi use

DVI interface has + 5V voltage, hot plug detect (HPD) voltage requirements from this voltage acquisition, HPD active level should be greater than 2.4V, so the receiving device HPD series resistance should generally be less than 10kΩ. Applications receiving device can also use this voltage power supply for the system, but should not be greater than the load current 50mA, preferably less than 10mA, the level micro hdmi cable needed to ensure the HPD. To ensure the normal startup interface, EDID memory power at best + 5V generated by the sender. In order to ensure a viable hardware circuit design, software must also have support. Optimized software process is the key to ensure the normal operation of the DVI interface system. DVI interface voice patch panel for applied research on digital television, flat panel TV's, even more critical is the EDID (Extended Display Identification DATA, namely Extended Display Identification Data) programming, HDCP (High-bandwidth Digital Content Protection) function implementation. Those who are new to digital television applications, only after EDID and HDCP implemented on digital TV, DVI interface is the real digital TV interface. No broadcast there, how to use the correct method to output DVI video signal interfaces are accurate indicators of broadcast test, there is no one perfect way.
