Abstract:
1. A method for detecting advertising sections of a video signal, the method comprising: obtaining the video signal, wherein the video signal is capable of providing a plurality of frames according to a predetermined order to show a dynamic image; performing a difference comparing step to determine the difference between a first frame and a second frame successive to the first frame, if a difference between the first frame and the second frame is more than a threshold difference, providing a corresponding difference information for the first frame; performing a similarity comparing step to determine a similarity between a third frame and a fourth frame not consecutive to the third frame where a minimum number of frames separating the third and fourth frames is determined according to a minimum length of the advertising sections and frame rate, if the similarity between the third frame and the fourth frame is more than a threshold similarity, providing a corresponding similarity information for the third frame; and performing an advertising estimating step to determine which frames of the video signal belong to the advertising sections according to the difference information and the similarity information.
