Abstract

PURPOSE: To reduce memory capacity by storing a subordinate-screen signal only with a synchronizing signal removed in the memory of a picture-in-picture television set.
CONSTITUTION: A luminance signal for a subordinate screen is read out from memory 41 and a fringing signal is generated by DC reproduction part 60Y and mixed by insertion circuit 12 with a master-screen signal. Color-difference signals R-Y and B-Y stored in memories 45 and 46 through color-difference signal demodulation circuit 34 for the subordinate screen are mixed as fringing signals by DC reproduction parts 60R, 60G and 60B together with a G-Y signal mixed by matrix circuit 35 and after DC reproduction, they are mixed with master-screen color-difference signals by insertion circuits 15∼17 respectively.
