ABSTRACT:
Apparatus and methods are provided for connecting video components. In one embodiment the apparatus includes a notch filter for filtering frequencies of a first channel from a first video source, the first video source having a plurality of channels, to form a notch filter output having each of the plurality of channels except the frequencies of the first channel, a bandpass filter for filtering a second video source to pass only frequencies in a second channel in the second video source having the same frequencies as the frequencies of the first channel to form a bandpass filter output, and a summer for summing the notch filter output and the bandpass filter output to form a summed output. In another embodiment the apparatus includes a signal splitter for splitting a first input signal and providing a first and second output, the second output coupled to and providing the first video source into the notch filter.
