Abstract
A secondary signal is processed and injected into a primary video signal. The injection level of the secondary signal is dynamically controlled to reduce transmission errors in the secondary signal, and to minimize interference and power level limitations. The injection level of the secondary signal may be based on video analysis of the primary signal or on error information fed back from a receiver which receives the transmitted secondary signal.
