In particular, owing to the built-in SYNC-SEP (synchronous separa-  
tion) circuit, the synchronous correction circuit, external circuits can  
be decrease and character turbulence that occurs when superim-  
posing can be reduced. The processor is suitable for AV systems  
such as VTRs, LDs, and so on.
