Study of Digital Video Interface (DVI) Hardware Design In Multimedia System

In multimedia system, some digital display devices often are adopted. At this time if still select conventional analog interface, digital signal from person computer (PC) need be switched twice by D/A and A/D, lost of video signal will emerge, so a kind of new interface, DVI technology often need be studied. Combining with real project, this paper introduces the detailed development methods of Digital Video Interface (DVI) transmitter and receiver in multimedia systems. These include the arranging of the architecture of Digital Video Interface (DVI) transmitter and receiver, the design of encoder and decoder circuit, clock recovery circuits, and etc. in addition selecting and designing of all kinds phase locked loop in hardware system were discussed in detail. These can offer a kind of reference method for developing of Digital Video Interface (DVI) transmitter and receiver video processing hardware in multimedia Systems.
