Abstract
An apparatus and method for detecting vertical blanking interval (VBI) is disclosed. The apparatus can automatically detect the presence and type of a VBI signal, so as to perform corresponding VBI decoding subsequently. The apparatus includes a digitizing module and a detecting module. The digitizing module converts a television signal into a digital signal according to a level value. The detecting module detects if the digital signal includes a VBI signal, and if yes, further determines the type of the VBI signal.
