ABSTRACT:
In a video signal reproducing apparatus, the changing time of a sub-video signal is adjusted, by a time-adjusting circuit, so as to be synchronized with the changing of a frame of a main video signal from the output of an interlace-scan-video-signal converter. And the sub-signal is added to the output of an interlace-scan converter by an adder. The output of the adder is converted into a progressive-scan video signal in synchronism with the boundary of frames of main video signal by the progressive-scan video signal converter. In the reproducing apparatus, even in the case that the sub-video signal is recorded without synchronism with the frames of the main video signal, an irregular frame is not generated even when the sub-video changes. And a single field of the sub-video does not leave or is not visible.
