Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Referring to Fig.1, a kind of step flow chart of video identifier embodiment of the method for the invention is shown, can specifically include
Following steps：
Step 101, the corresponding barrage information of video is obtained, video is included at least in the barrage information when playing when difference
Between the barrage number of reviews put.
In the embodiment of the present invention, which specifically can be video and broadcasts
The module or device putting device or being built in video player, are also possible to the device independently of video player, still
It can be interacted with video player.
The embodiment of the present invention is identified video using barrage information.
Firstly, barrage is this dynamic menu of video and non-textual " annotation ".Share and interact, this pole mutual
Other people thought can be learned by targetedly " annotating " people for making any one watch this video, learn other people sense
Touching, plays an important role when helping us to understand video more accurate, comprehensive or polynaryly.And when a certain section specific
In, the clothing of hero, a unremarkable lines, movement etc. can all cause the comment of viewer, barrage comment
Number has just directly reacted the temperature of corresponding video clip.
Secondly, barrage is the content tab of a having time sequence, the comment of each barrage, is all the time shaft with video
It is corresponding, it further says, it is corresponding to each picture segments with video.In the past, people to a video into
When row is commented, often carry out whole commentary, and barrage provides a good mode, allow people can to a picture into
Row is commented, also, these are commented all by high polymeric under same section of picture, and is no longer discrete be distributed under comment box.Bullet
The concentration of curtain is almost positively correlated with the excellent degree of video content.The device i.e. can be using barrage information come to video accordingly
It is identified.
In this step, which obtains the corresponding barrage information of video first from server, which specifically may be used
To be barrage list, wherein at least to include the barrage number of reviews of video different time points when playing, the barrage information
It may include specific barrage comment content.
Step 102, determine that barrage number of reviews is more than or equal to the time point of threshold value in barrage information.
Assuming that the barrage number of reviews of video different time points when playing is as shown in Fig. 2, horizontal axis is view in barrage information
Frequency play time, the longitudinal axis are barrage number of reviews, then a threshold value W can be set in the device, determines barrage according to the threshold value
Number of reviews is greater than or equal to the time point of the threshold value, and continuous time point forms the period.
Step 103, time point corresponding video clip is determined.
After determining time point in upper step, these time points corresponding video frame constitutes corresponding piece of video
Section.These video clips are exactly that user comment is more, the higher video of attention rate, due to barrage concentration almost with video
The excellent degree of content is positively correlated, so, these video clips also can serve as the pith in the video.
Step 104, the video clip is identified.
The device can be identified the video clip after determining important video clip.Identification means have more
Kind, referring specifically to the description of subsequent embodiment.
The embodiment of the present invention utilizes the corresponding relationship and barrage information dense between barrage information and video playback time
Incidence relation between degree and video clip significance level determines barrage number of reviews by obtaining the barrage information of video
Big video clip, and the video clip determined is identified, realize the mark to pith in video.The mark
Method improves the fineness and accuracy identified to important content in video, can effectively be identified, meet to video
User only watches the demand of important video clip in video.
In another embodiment of the invention, if it is random that server, which receives the barrage comment to video that user sends,
And not timing, then server is safeguarded barrage list be also to be commented in the addition barrage of not timing, be in real-time update
State can be when the device obtains the corresponding barrage information of video and play the video receiving user in the device
Request when, obtain and receive barrage information before the request, the barrage information be from portion's video begins with barrage to
Point is read to stop.
In another embodiment of the invention, the advertisement etc. in barrage may be included in the read barrage information of the device
Some useless information, then barrage number of reviews was greater than or equal to before the time point of threshold value in determining barrage information, such as Fig. 3
Shown, this method further includes：
Step 301, the useless barrage information in barrage information is identified.
In this step, which may include specific barrage comment content, which can be according to keyword
With etc. modes identify useless barrage information, such as the advertisement in barrage in barrage information etc..
Step 302, filtering useless barrage information.
After identifying useless barrage information, which can be filtered, specifically can directly be existed
The useless barrage information is deleted in barrage information.
After deleting the useless barrage information, then determine barrage information in barrage number of reviews be greater than or equal to threshold value when
Between point.
In another embodiment, can also in determining barrage information barrage number of reviews be greater than or equal to threshold value time
Useless barrage information in point and then identification barrage information, is then marked, in the barrage number of reviews determined
More than or equal to existing useless barrage information is deleted in the comment of the barrage of threshold value, then count after deleting useless barrage information
The barrage that barrage number of reviews is greater than or equal to threshold value comments on corresponding time point.
By the above-mentioned filtering to useless barrage information, reduce the interference information when determining video clip, so that really
The video clip made is more accurate.
In another embodiment of the invention, there are many modes for identifying video clip：
First, the video clip determined can be extracted directly from video, only extracted to user's displaying
Video clip.
Second, the corresponding position of video clip can be identified in the broadcasting track of video.
Specifically, the corresponding position of video clip can also be gone out using different identification message identification in the broadcasting track of video
It sets, and the barrage number of reviews difference namely different identification information of the corresponding video clip of different identification information represent corresponding view
The temperature of frequency segment.It specifically can be and identify the corresponding position of video clip using different colours.
In another embodiment of the invention, as shown in figure 4, this method can also include：
Step 401, when playing video clip, control whether that the corresponding barrage of display video clip is commented according to user instructions
By content.
When user watches video, display can be issued by operations such as mouse clicks or close the finger that barrage comments on content
It enables, which, which can control display according to the instruction or close barrage, comments on content.
In addition, the barrage that the device can show or close a certain video clip according to instruction control comments on content.
It should be noted that for simple description, therefore, it is stated as a series of action groups for embodiment of the method
It closes, but those skilled in the art should understand that, embodiment of that present invention are not limited by the describe sequence of actions, because according to
According to the embodiment of the present invention, some steps may be performed in other sequences or simultaneously.Secondly, those skilled in the art also should
Know, the embodiments described in the specification are all preferred embodiments, and the related movement not necessarily present invention is implemented
