Patent abstract

When a CCU is supplied with a 60i format compliant video signal generated by applying a frame conversion based on the 2-3 pull down technique to a 24 PsF format compliant video signal, the CCU performs a reverse frame conversion corresponding to this frame conversion. When the CCU is supplied with a 60i format pure video signal with no frame conversion applied, the CCU performs a frame conversion by skipping fields in units of frames in accordance with a conversion ratio. The CCU selectively changes the two conversions in accordance with 60i format compliant video signals supplied.
