Abstract
A video modulator is presented. The modulator includes a video input interface, a video modulation circuit, a video output interface, a communication interface, and control circuitry. The video input interface is configured to receive a video signal to be modulated, the video modulation circuit is configured to modulate the video signal, and the video output interface is configured to transmit the modulated video signal. The communication interface is configured to receive a command via a communication link to control the video modulator. The control circuitry is configured to receive the command from the communication interface and to control at least one of the video input interface, the video modulation circuit, and the video output interface based on the command.
