Abstract
A video system includes a VCR coupled to the output of a summation circuit that has two inputs. The first input is supplied from an active splitter and the second from a UHF modulator/upconverter which has its input connected to the active splitter through a decoder/converter. The output of the summation circuit is coupled through a passive splitter to the VCR and the VCR is connected to the TV receiver in normal fashion. The arrangement permits full use of the VCR capabilities.
