CONSTITUTION: Transmission mode gray scale data is input(2201). A reflection mode effective gray scale voltage range different from a transmission mode effective gray scale voltage range is reflected on the transmission mode gray scale data to convert the transmission mode gray scale data into a reflection mode gray scale data(2203). An integer part of the reflection mode gray scale data is extracted to produce the first reflection mode gray scale data(2205). A decimal part of the reflection mode gray scale data is extracted to produce control data(2207). The second reflection mode gray scale data is obtained by averaging the first reflection mode gray scale data for N frames using a frame synchronizing signal and the control data(2209). The second reflection mode gray scale data is filled with pseudo gray scale values corresponding to a difference between the number of transmission mode gray scales and the number of reflection mode gray scales to produce the third reflection mode gray scale data(2211). In the case of transmission mode, the transmission mode gray scale data is provided to generate a transmission mode gray scale voltage(2217). In the case of reflection mode, the third reflection mode gray scale data is provided to generate a reflection mode gray scale voltage(2215).

Abstract: PURPOSE: A fast digital video interface controlling method using a compression technique and a DVI transmitter and receiver using the controlling method are provided to adaptively control a bit rate of a transmission channel using the DVI controlling method. CONSTITUTION: A DVI transmitter reads video data to be transmitted to a display. A controller of the DVI transmitter determines a compression ratio of the video data to be transmitted. A 1/N clock generator reduces a clock frequency in proportion to the compression ratio and a compressor of each channel of the DVI transmitter compresses the video data. The compressed data is TMDS-coded and transmitted to a DVI receiver. The DVI receiver decodes the TMDS-coded data. A controller of the DVI receiver receives compression information and delivers the information to an N clock generator. A clock generator of the DVI receiver restores the clock frequency into the original frequency, and a restoring circuit of each channel restores the compressed data.
