Abstract

PURPOSE:To obtain a video processor which can be used for various uses, by converting video signals and analog R.G.B signals into each other and selectively outputting the converted analog R.G.B signals and analog R.G.B signals inputted from the outside. CONSTITUTION:Video signals from various kinds of AV equipment groups inputted from an input connector section 8 are amplified by an amplifier which is not shown in the figure and supplied to a decoder circuit 12 and synchronizing separator circuit 13. At the decoder circuit 12 chrominance demodulation of the video signals is performed and analog R.G.B signals are extracted and sent to an R.G.B switching circuit 14. On the other hand, R.G.B signals from a connector section 11 are also supplied to the R.G.B switching circuit 14 and switching of the circuit 14 is performed in accordance with the instruction of a Ys signal from the connector section 11. Selected R.G.B signals are sent to home TV sets, etc., through a connector 10 and, at the same time, converted into video signals at an encoder section 16. The converted video signals are also sent to equipment groups which can input video signals as well.
