Title: Deciding circuit
Inventor: OCHIAI YOSHIO
IPC: H04N9/00
Filed: 1986-03-24
Abstract: PURPOSE:To surely decide both broadcasting systems with a simple constitution by detecting the level of a burst signal available at the output of a comb-line filter and discriminating a broadcasting signal made by a PAL-M system from a one made by an NTSC system. CONSTITUTION:A subtractor circuit 6 subtracts a video signal supplied to a terminal 1 and a video signal before 2H that is supplied through delay circuits 2 and 4, thereby obtaining a chroma signal included in the broadcasting signal made by the PAL-M system. After a burst flag circuit 8 removes only burst signals appearing at every H from the signal, a detector 11 detects a signal obtained in such a way that a ceramic filter 9 extracts a signal close to the frequency of a subcarrier. If the extracted signal is a one made by the PAL-M system, a signal with the prescribed amplitude appears at every H. Whereas it is a one made by the NTSC system, a signal with a slight amplitude can be obtained. Accordingly the signal is level-detected by a level detector 16 through a resonance circuit and a DC modulation circuit 15, whereby both systems can be discriminated.
