Apparatus and associated methodology for generating a picture-in-picture display from two video screens
Abstract:
A reproducing apparatus simultaneously reproduces a first video signal and a second video signal reproduced at any timing against the first video signal. A first (second) converting section outputs the first (second) video signal having a first frame frequency alternately for three successive frames and two successive frames to convert the first (second) video signal having the first frame frequency into the video signal having a second frame frequency. They have a relationship of 2 to 5. A controlling section performs control such that timing at which a field group of the three successive frames of the first video signal having the second frame signal is changed to a field group of the two successive frames thereof matches timing at which a field group of the three successive frames of the second video signal having the second frame signal is changed to a field group of the two successive frames thereof.
