Digital Video Interface DVI (Digital Visual Interface) is a digital flat panel display interface standards , its core content is TMDS (Transition Minimized Differential Signal) - the smallest change in the differential signal . Demonstrated on the basis of in -depth understanding and research DVI interface standards , and TMDS electrical transmission standard protocol , based on the overall design of the TMDS the digital video transmission and codec technology demonstration platform . Details and analysis as the interface to the core of the TMDS Transition Minimized Differential Signaling logic architecture , communication protocol encoding algorithm and decoding algorithm . The design and production of the PCB board . Encoding and decoding circuit according to specifications of DVI1.0 , research and design . IP core using VerilogHHDL language to achieve encoding , decoding . Instead TFP510 TFP501 validated correctly implemented as a transmitter and receiver of the video data encoding , decoding, and the differential transmission . The encoder circuit is part of the transmitter , and its main function is to become the the 10bit signal output to the the 8bit video signal and control signal encoding 2bit serializer . By the hardware description language , the formation of the independent encoding IP core , DC balanced , so that the encoded output of the logic \The decoding circuit is part of the receiver , and its main function is to pass over from the transmitter 10bit decoding the encoded signals , the video signal of the decoded 8bit 2bit control signal and 1bit enable signal DE . To achieve a separation of the data signal and the control signal . Finally, the specific method of debugging and debug results , and analysis of the factors that affect the integrity of the high-frequency signal and circuit noise . The theoretical analysis and debugging results show that the experimental circuit board design is correct , to meet the technical requirements .
