Abstract:
A video standard detector and operation method thereof are provided. The video standard detector includes a low pass filter (LPF) unit and a standard detector unit. The LPF filters a baseband signal. The feature detector detects vertical synchronization information of the baseband signal and horizontal synchronization information of the baseband signal using the output of the LPF, and determines the video standard corresponding to the baseband signal according to the vertical synchronization information and the horizontal synchronization information.
