A controlling method for a high speed DVI using compression technique and a DVI transmitter and Receiver using the method

摘要

Step invention is to read the image data to be transmitted to, parts of the DVI transmitter displayed on the DVI transmitter and the receiver and using this method for controlling a high-speed DVI; Further comprising: a control section of the DVI transmitter determines a compression rate of image data to be the transmission; The method comprising in proportion to the compression ratio, a clock generator reduces the clock frequency and the compression of the image data compressor of each channel of the DVI transmitter; Transmitting the compressed data to the DVI receiver by TMDS encoding; The method comprising the DVI receiver decodes the TMDS-coded data; And further comprising: a control section of the DVI receiver passed to the clock generator to receive the compressed information; The clock generator of the DVI receiver, restoring the clock frequency to the original frequency, and characterized in that it comprises the step of restoring the compressed data restoration circuit for each channel. According to the invention, it is possible to transmit data at high speed between a transmitter and a DVI receiver, and prevents malfunction occurring in the transmission channel, which can implement the hardware for high-speed transmission in a simple way.
