- the video frame buffer 4 always records the relevant information of the current section for 5 to 10 seconds. According to the calculation of 25 frames per second video, the program content of about 200 frames needs to be stored.
- the actual amount of storage required is related to the resolution ratio of the television picture and whether a certain image compression algorithm is used. For example, it may require several megabytes of storage space.
- the following method uses only the relevant two frames of information. In fact, it is only necessary to store the image of the two adjacent frames currently being processed and the retained image frame before the lens shearing, which can greatly Reduce the amount of storage required.
- the television program control device 2 In addition to inputting video images to the display 3, the television program control device 2 also stores in the video frame buffer 4 Video frame of the first 5 to 10 seconds of the currently received video content.

- Fig. 3a shows the frequency of change of the video image of an advertisement
- Fig. 3b shows the frequency of change of the video image of an ordinary television program.
- the location of the spikes in the figure indicates that the image has changed significantly here. It can be seen from the figure that more than 5 shears can be detected in an advertisement of about 8 seconds, and the length of the shot does not exceed two seconds, while in an ordinary TV program (as shown in Figure 3b) 5 Seconds or even longer shots are not uncommon, but it can be seen that the frequency of changes in advertising shots is usually significantly faster than that of ordinary programs.
- long shot detection is used, that is, if the time interval of shot cut is not less than Threshold, then the advertising program is considered to have ended.
- the threshold can be set to about 5 seconds, or adjusted according to specific conditions.
- the basic principle of lens shear detection is to find a better method for comparing differences between frames to detect spikes.
- the point where the difference exceeds the set point is the lens switching point.
- color histogram matching is used to make the frame Analysis of differences.
- the specific calculation method is the same as described above, and the description is omitted here.

- step S202 the receiver 8 detects whether or not a command prompting the end of the advertisement transmitted from the signal transmitter 9 on the remote control side is received. If the determination result in step S202 is negative, it continues to detect whether a command prompting the end of the advertisement is received.
- step S202 If it is determined in step S202 that a command indicating the end of the advertisement is received, a start signal is provided to the controller 5 to start the controller 5 in step S203.
- the controller 5 controls the video lens shear detection and calculation device 6 to detect a sudden change of the video image frame, and stores in the buffer 4 the previous frame where the video frame has suddenly changed as a key frame for prompting.
- step S204 ' it is judged whether the newly received video frame stored in the buffer matches the prompt key frame (correlation).
- step S207 If the newly received video image frame matches the prompt key frame (relevant), or the time interval of lens shearing is greater than or equal to a predetermined threshold, the flow goes to step S207, and the prompt signal generating device 7 is controlled to generate an advertisement end prompt signal, and Appropriate methods, such as sounding, or displaying cue subtitles to alert viewers that the advertisement playback is over. If it is determined in step S204 that the newly received image does not match (not correlate with) the stored prompt key frame, and the time interval of lens cut is less than a predetermined threshold, the flow proceeds to step S205, it is determined that the advertisement playback has not ended, and returns Step S204 continues to perform correlation detection until the received detected received image frame matches the stored prompt key frame or is related.
- the method for detecting image matching or correlation, or cutting an advertisement image to a television program image can use the algorithm used in the description of the device of the present invention, and will not be repeated here.
