<p>Video signals are transmitted between computers in a multicomputer network, with automatic level control. A reference voltage is transmitted, by the transmitting computer station, during either the horizontal or vertical synchronising pulses of the video signals. The reference voltage is detected by the receiving computer stations, and is used by each receiving computer station to provide the correct level of amplification to the received video colour signals, thereby permitting a constant display level to be achieved at the monitor of receiving station irrespective of cable and equipment loadings and other factors influencing the level of the received video signals.</p> |
