Patent ID: 8237860

Claim:
A video editing detection system, which receives plural fields of a video datastream for detecting a video editing in the video datastream, the system comprising: a film mode detector, which receives a previous field F[N−1] and a next field F[N+1] respectively of the video datastream to accordingly determine whether the video datastream is a film mode or not; a sawtooth detector, which receives a current field F[N] and the next field F[N+1] respectively of the video datastream to thereby determine whether a sawtooth is present to the next field F[N+1] based on a field energy of the current field F[N] and a frame energy of the current field F[N] and next field F[N+1]; and a scene detector, which receives the current field F[N], the next field F[N+1] and the previous field F[N−1] in order to calculate a field brightness difference between the current field F[N] and the previous and next fields F[N−1] and F[N+1], and accordingly determines whether a scene change occurs; wherein, when the video datastream is the film mode and the scene change occurs, the video datastream is determined to have the video editing.
