Abstract:
1. A video transmission system, comprising: a video source; a first video transmission path that receives a video signal from the video source and provides a first video output signal and an error signal, the error signal having a first state when no error is detected in the first video output signal and a second state upon detection of an error in the first video output signal; a second video transmission path that receives a video signal from the video source and provides a second video output signal; and a video protection switch that receives the first and second video output signals from the first and second video transmission paths and provides the first video output signal when the error signal is in the first state and providing the second video output signal when the error signal is in the second state, wherein the video protection switch replaces only the first video output signal when the error signal is in the second state, while other video output signals continue to be provided from the first transmission path.
