<p>PURPOSE:To transmit video signals in a long distance with inexpensive equipments by incorporating timing common-mode pulses in a part equivalent to the synchronizing signals of respective color picture signals and transmitting them in a transmission part and selecting delay image signals in a reception part. CONSTITUTION:In a timing common-mode pulse incorporating part 10 on a transmission side, the timing common-mode pulses generated from the synchronizing signals and dot clocks are incorporated in the synchronizing signal part of the image signals to be transmitted in a long distance and transmitted to a latch circuit 5. In the circuit 5, the image signals and the synchronizing signals are transmitted to a driver 6. In the meantime, the dot clocks are branched before being inputted to the circuit 5 and are inputted to the driver 6. In the driver 6, they are sent out to a transmission line 7. On a reception side, they are received in a receiver 8 and the video signals are latched in the latch circuit 9. Then, in a timing common-mode part 50, (n) pieces of the delay image signals are prepared for the respective color picture signals and the delay image signals are selected based on the reprepared timing common-mode pulses.</p> |
