 The ideal embodiment of the squelch control device for video output on the optical disc device based on the present invention will be described in detail below with reference to the accompanying drawings.
 First of all, the video output squelch control device based on the present invention is applicable to various types of optical disk equipment such as DVD player (DVD-Player) or DVD recorder (DVD-Recorder). For example, as shown in FIG. 2 , the optical disc device includes a video decoder chip 20 , a video squelch circuit 21 , an RCA socket, a connection detection unit 23 and the like.
 On the other hand, the video squelch circuit 21 is composed of several squelch sections (for example: M1, M2, M3) that can switch the squelch action independently. With reference to Fig. 1 and the previous description, on the video decoder chip 20, after the MPEG video data stream read and reproduced from DVD and other optical discs is decoded into digital video data, th...
