Abstract
The present invention provides an advertisement detection method and system. The method comprises the steps of when a play device detects and finds video playing, acquiring, according to a preset frame algorithm, a video hopping frame threshold of every two adjacent frames of images in a video played currently and a histogram square error of every two adjacent frames of image, and then acquiring a mute time period in the video played currently, wherein the video hopping frame thresholds are within a preset slide window threshold; comparing the histogram square error of every two adjacent frames of image in the video played currently with the video hopping frame threshold, and determining whether the mute time period is within a preset assigned mute interval threshold range; and when the histogram square error of two adjacent frames of image in the video played currently is greater than the video hopping frame threshold, and the mute time period is within the assigned mute interval threshold range, determining that the advertisement is played. According to the method, the frame difference of two adjacent frames of image in the video played currently and the mute time period are detected so as to determine whether an advertisement is played, so that advertisement embedment position in the video is detected precisely.

Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment. Should be appreciated that specific embodiment described herein is used only for explaining the present invention, be not intended to limit the present invention.
Refer to the flow chart that Fig. 1, Fig. 1 are commercial detection method preferred embodiment of the present invention. As it is shown in figure 1, described method includes step:
When S100, playback equipment detect video playback, obtain the video saltus step frame threshold value of all adjacent two two field pictures in default sliding window threshold value in currently playing video and the rectangular histogram difference of two squares of every adjacent two two field pictures according to default frame algorithm, then obtain the time periods of silence in currently playing video.
In embodiments of the invention, by the rectangular histogram difference of two squares to the video saltus step frame threshold value of adjacent two two field pictures all in default sliding window threshold value and every adjacent two two field pictures, and the detection of time periods of silence and computing judge to realize advertisement is interted in video the detection of position. Owing to common advertisement has following two form: one is not only include dynamic video but also include the advertisement of audio frequency, two is the advertisement including static video (namely poster or picture) and audio frequency. Because insert the moment played out in advertisement, often there is the short time quiet or volume moment reduces, if also have advertisement video to play simultaneously, there is bigger picture frame saltus step. If the picture frame saltus step in single detection a certain moment or time periods of silence, all it is not enough to the broadcasting judging now whether carrying out advertisement. Only combine both to analyze simultaneously, could accurately judge currently whether have started to play advertisement.
Wherein, sliding window is a kind of flow control technique. Sliding window protocol is used to improve a kind of technology of handling capacity simultaneously, namely allows that sender transmitted additional bag before receiving any response, and recipient tells that sender at a time can send how many bag (title window size).Adopting sliding window to be transmitted controlling in Transmission Control Protocol, the size of sliding window means that recipient also has great relief area to may be used for receiving data. Sender can be come it is determined that send the data of how many bytes by the size of sliding window. When sliding window is 0, sender generally can not retransmit datagram.
Step S200, by currently playing video often the rectangular histogram difference of two squares and the described video saltus step frame threshold value of adjacent two two field pictures compare, and judge that described time periods of silence is whether in default appointment mute interval threshold range.
Step S300, when the rectangular histogram difference of two squares of two two field pictures adjacent in currently playing video is more than described video saltus step frame threshold value, and described time periods of silence is in described appointment mute interval threshold range, then be judged to that advertisement is play.
Obtain the video saltus step frame threshold value of all adjacent two two field pictures in default sliding window threshold value in currently playing video and the rectangular histogram difference of two squares of every adjacent two two field pictures in the step s 100, after obtaining the time periods of silence in currently playing video again, the rectangular histogram difference of two squares of often adjacent two two field pictures and video saltus step frame threshold value need to be compared, and judge that described time periods of silence is whether in described appointment mute interval threshold range simultaneously, meet above-mentioned two condition only simultaneously, just can determine that currently playing content is advertisement.
Further carry out example, also include before obtaining play parameter in described step S100:
Step S10, preset the frame algorithm for calculating video saltus step frame threshold value and the every rectangular histogram difference of two squares of adjacent two two field pictures, and sliding window threshold value is set and specifies mute interval threshold range.
It is analyzed known according to play-back technology is inserted in existing advertisement, advertisement is inserted the mute time of moment and is typically in more than 20ms, and less than 1s, so can according to this empirical value, exclusive PCR quiet, the short time quiet position of moment is inserted in detection advertisement, namely described appointment mute interval threshold range is set to 20ms-1s.
Further carry out example, specifically include as in figure 2 it is shown, obtain play parameter in described step S100:

When current video broadcasting content is advertisement, then there is the bigger rectangular histogram difference of two squares (namely frame is poor) with the image of former frame. Therefore the rectangular histogram difference of two squares S of often adjacent two two field pictures obtained in step S101j, namely can determine whether the difference size of image consecutive frame, the frame difference that step afterwards may utilize acquisition is poor to compare to determine the frame whether this frame difference is bigger with the video saltus step frame threshold value obtained.
Step S102, rectangular histogram difference of two squares S according to adjacent two two field pictures all in described sliding window threshold valuejObtain rectangular histogram difference of two squares average S, wherein, SxRepresenting the rectangular histogram difference of two squares of xth two field picture and xth-1 two field picture, N represents described default sliding window threshold size;
Step S103, obtaining video saltus step frame threshold value A according to the long-pending of described rectangular histogram difference of two squares average S and the empirical coefficient K preset, wherein K is the integer of 5-10.
In the enforcement of the present invention, described video saltus step frame threshold value A is not pre-set, but by the rectangular histogram difference of two squares S according to adjacent two two field pictures all in described sliding window threshold value in video display processjObtain the long-pending acquisition of rectangular histogram difference of two squares average and default empirical coefficient K. When being embodied as, described empirical coefficient K is set to 7.
Step S104, the time periods of silence T obtained in currently playing video, wherein T is the real number more than 0.
Visible, by above-mentioned detection method, when the rectangular histogram difference of two squares of two two field pictures adjacent in currently playing video is more than video saltus step frame threshold value, and time periods of silence is in appointment mute interval threshold range, then it is judged to that advertisement is play, it is achieved that the accurate detection of advertisement on position.
