Abstract
PURPOSE:To prevent a black stripe part from appearing on a screen by superimposing a video signal to a section to include a vertical synchronizing signal at a prescribed level at the time of scanning a CLV disc. CONSTITUTION:At the time of scanning, a time constant circuit 4 generates a pulse corresponding to the section of a prescribed width to include at least the vertical synchronizing signal of a reproducing video signal, and a deleting circuit 1 removes at least a luminance signal in the section corresponding to the pulse from the time constant circuit 4 and outputs the video signal. The video signal at the prescribed level outputted from a generating circuit 5 is inserted by an inserting circuit 2 into the section to be deleted by the deleting circuit 1 of the video signal. In such a way, the video signal at the prescribed level is superimposed to a vertical retrace section. Thus, since a test signal, a reference signal, a code signal, etc., to be inserted into the vertical retrace section can be removed, and simultaneously, the video signal at the prescribed level is inserted into such a part, the screen of the part can be made not black but gray, for example, and an easy-to-watch screen can be obtained.
