APPARATUS FOR LONG-DISTANCE DIGITAL SIGNAL CONTROLL USING H.264 COMPRESSION

摘要

A long-distance digital signal controlling device which uses H.264 compression is provided to perform power supply and image output at the same time by converting an analog signal into a digital signal, compressing the converted digital signal based on H.264 compression and transmitting the compressed digital signal through a UTP cable. A transmission end(100) includes the followings: a central processor(110) which transfers an inputted digital signal to an H.264 compressor(120); the H.264 compressor which compresses the inputted signal and transfers the compressed signal to an image and voice transmitter(130); and the image and voice transmitter which transfers the inputted signal to a receiving end. The receiving end comprises the followings: an H.264 restorer(220) which restores a compressed image and voice; and a CPU(210) which transfers an image and a voice to an output unit.
