Abstract:
An apparatus to convert a first video signal in a first video format to a second video signal in a second video format that is incompatible with the first video format, comprising:a frame interpolator that produces a plurality of interpolated frames from the first video signal by using motion vectors obtained therefrom, the plurality of interpolated frames being derived from different combinations of consecutive frames of the first video signal; a switch that selects one of the plurality of interpolated frames to produce the second video signal; a plurality of difference detectors that detect differences between the consecutive frames of the first video signals; and a switching controller that finds a change in the first video signal by examining the differences detected by the difference detectors and controls the switch to choose such interpolated frames that are derived only from correlated source frames before the change or after the change in the first video signal.
