IMAGE COMMUNICATION SYSTEM FOR HAVING COMMUNICATION LINES BASED ON TWISTED PAIR CABLES

摘要

The present invention is unbalanced (Unbalance) signaling method of video communication signal equilibrium (Balance) signaling method to convert the TPC (Twisted Pair Cables) to establish a communication line for through transmission and, TPC communication lines Throughout received that a balanced signal way relates to an image communication signal to the image communication system with a TPC-based communication line is constructed to enable one-to-one image communication or one-to-many, and many to many relationships between the video communication terminal comprising a transceiver for converting the unbalanced signal scheme. ; According to the present invention, as well as balanced signaling transfer image communication signal, as necessary TPC communication line a so be used as a power supply line, a coaxial cable with unbalanced signaling transfer image communication signal or a dedicated cable using conventional of the can, the system administration and maintenance easily built the system as compared to an image communication system, has the advantage that the cable laying cost is low cost consuming, and by a balanced signal processing enough protection for the image communication signals from various kinds of noise of the consumer which it produces the effect of sufficiently maintaining communication quality enough to satisfy the needs. ; Image communication system, TPC, UTP, STP, FTP, cable
