IPC: H04N5/91
Filed: 1992-01-16
Abstract: PURPOSE:To accurately discriminate whether or not a copy guard is inserted in a video signal by dividing a vertical blanking period of the video signal and detecting a pseudo synchronization pulse from consecutive division periods. CONSTITUTION:A video signal inputted from an input terminal 1 to a copy prevention processing presence detection circuit 100 is fed to a synchronizing separator circuit 2, from which horizontal synchronizing signal and vertical synchronizing signal H, V are obtained.

Filed: 1986-02-10
Abstract: PURPOSE:To apply a flat plastic package to a power IC by extending the area of a tab made of a metal to the whole planar contour of the package while thinly forming the thickness of the package section on the back of the tab. CONSTITUTION:In a semiconductor device 1 constituted as a power system linear IC, a tab 3 made of a metal holding a semiconductor chip is molded and sealed into a plastic package 6 together with leads 4.
