Problems solved by technology

For viewers, these commercial segments often interfere with the continuity of normal programs, cause trouble for viewers when watching normal programs, and waste viewers' time
When the viewer wants to record the normal program as a reference in the future (or to record it and play it later), these commercial segments will consume the resources of the user to record the video signal, and cause the user to be unable to conveniently and quickly retrieve, Manage and access the recorded video signal, but in the conventional technology, the current technology lacks the detection mechanism and system of this kind of video signal advertising segment

Embodiment Construction

[0025] Please refer to Figure 1 first. FIG. 1 is a schematic diagram of a video signal 10 . The video signal 10 can provide different frames at different times sequentially, such as sequentially providing frames F(a1), F(a1+1) ... to F(a2), F(b1) to F(b2) until frame F( k1) to F(k2) and so on to present dynamic images. As discussed above, in the video signal provided by the broadcasting media, commercial segments will be interspersed between normal programs, while in the video signal 10 of Fig. Advertisement segment Ad; wherein, normal program segment Sp1 has frames F(a1), F(a1+1) to F(a2), F(b1) to F(b2)...until F(c1) to F(c2) and F(d1) to F(d2); normal program segment Sp2 has frames F(h1) to F(h2), F(i1) to F(i2), F(j1) to F(j2) and F(k1 ) to F(k2) and so on, while frames F(e1) to F(e2), F(f1) to F(f2) and so on until frames F(g1) to F(g2) are used to present the advertisement segment Ad dynamic image.

Abstract

This invention provides a method for carrying out advertisement detection to a video signal and a related system, In the video signals provided by broadcast and TV media, some broadcast segments are inserted between normal programs which makes the adjacent pictures discontinuous at the insertion is replayed after the advertisement is finished. This invention firstly detects if the picture between two adjacent frame is continuous in the video signals and scarches for frame with similar pictures frame, if so, it can evaluate frames covering advertisement between the two frame to realize the detection.

Description

technical field [0001] The present invention provides a method and a related system for detecting advertisement segments in a video signal, in particular a method and a related system for detecting advertisements by comparing similarities and differences between frames with high efficiency. Background technique [0002] The audiovisual program service provided by cable or wireless broadcast media is one of the most important information sources in the modern information society. Viewers can obtain useful news, knowledge, information, or audio-visual entertainment that can relieve the body and mind from audio-visual program services. However, under commercial considerations, the audio-visual programs provided by broadcasting media often have commercial segments interspersed between normal programs. For viewers, these advertisement clips often interfere with the continuity of normal programs, cause trouble for viewers to watch normal programs, and waste the time of viewers. ...
