ABSTRACT:
A system for supplying control signals, DC power and video signals to a plurality of video system components includes a DC signal splitter and an RF signal splitter. The RF signal splitter carries video signal to a multiplicity of components. The DC signal splitter carries DC power and low frequency control signals to the multiplicity of components. Each of the signal paths for the DC power and the control signals includes DC short circuit protection, which prevents the occurrence of a short circuit in one output from causing the entire system to fail.
