Abstract
A secondary signal is processed and injected into a primary color video signal. The timing of the subsequent transmission of the secondary signal is controlled by timing signals. The timing signals also control the transmission of a carrier burst prior to the transmission of the secondary data signal. This carrier burst is used by a receiver to synchronize with the transmitter, reduce transmission errors and to indicate that a data transmission is to follow.
