Embodiment Construction

[0011] An embodiment of the present invention can be divided into two parts: storing the key information of the TV signal and detecting whether the content of the signal is repeated.

[0012] The first part is to store key information used to extract information that can be used for subsequent identification of each frame in the TV being played. Such as figure 1 as shown, figure 1 The large frame of the TV signal is the area of ​​the TV signal. The upper, lower, left, and right edges of the TV signal are not used for detection. Each side of the edge part can be set within 5%-15% of the TV signal itself according to needs, that is to say, the length of the central part The width accounts for 70%-90% of the length and width of the TV signal respectively. The central area is divided into 8*8 64 small areas on average. When extracting information, it is necessary to extract a frame of image from the video image at a fixed interval T (such as 1 second) for feature value extracti...

Abstract

The invention discloses a method and a device for detecting duplicate contents in television signals. The method comprises the following steps: evenly dividing the central zone of a television signal into four large zones in the size of 2*2, and dividing the four large zones into 64 small zones in the size of 8*8; extracting and storing the characteristic information of a group of images in a real-time television signal in a YCbCr color space at fixed time intervals, wherein the group of the images comprise a one-frame key image and 16-frame ordinary images; comparing the characteristic information of the key image of an image group to be detected with the characteristic information of the key image of a stored image group, and then judging whether the two types of characteristic information are the same, if not, judging that the two types of characteristic information are non-repetitive contents; otherwise, comparing the characteristic information of the 16 ordinary images of the image group to be detected with the characteristic information of the 16 ordinary images of the stored image group; and if at least 62 small zones are the same, judging that the two types of the characteristic information are repeated contents, otherwise being non-repetitive contents.

Description

technical field [0001] The invention relates to a method and apparatus for detecting repetitive content in a television signal. Background technique [0002] Now a lot of TV programs are often filled with many commercial advertisements, especially in the middle of some hit programs, often have a lot of advertisements. Advertisements broadcast by TV stations are generally repetitive, and an advertisement is often broadcast several times or even dozens of times. [0003] Users generally can only be forced to watch these advertisements, or switch to temporarily watch other programs, and this often causes users to change channels continuously. user experience. Contents of the invention [0004] The present invention provides a method and device for detecting repeated content in television signals which can solve the above problems. [0005] In a first aspect, a method for detecting repeated content in a television signal is provided, the method comprising the steps of: divi...
