PROBLEM TO BE SOLVED: To provide a display unit reducing wiring members and operation cost, facilitating operation, and having proper performance, when used in a display system. SOLUTION: A receiver 31 receives differential analog video signals from a long distance transmission line LL1 and converts them into unbalanced analog video signals to output to an analog video signal line LA2 that is internal wiring. A frequency response characteristics corrector 11 inside the receiver 31 corrects the frequency response characteristics attenuated mainly by the long distance transmission line LL1, and a delay corrector 12 corrects differences of propagation delay. A transmitter 34 receives the unbalanced analog video signals from the analog video signal line LA2 and converts them into balanced differential analog video signals to transmit to a long distance transmission line LL2 as differential analog video signals. A video output circuit 36 outputs the unbalanced analog video signals or unbalanced digital video signals to a video signal line LV 1 as unbalanced video signals. COPYRIGHT: (C)2010,JPO&INPIT |
