Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiment.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the application's protection.
In the present embodiment, the first electronic equipment is determined and in video data, is met pre-conditioned key video sequence frame; In video data, add the video tab of mark key video sequence frame; The second electronic equipment obtains the video data of this interpolation video tab, can determine fast key video sequence frame according to video tab, and in navigation position corresponding to the frame of key video sequence described in navigation information, export the information of described key video sequence frame, this information is used for key video sequence frame to point out, thereby can avoid blindly searching, be conducive to video frequency searching, can realize fast video frequency searching, save video and search the time, improve recall precision.
Below in conjunction with accompanying drawing, the application's embodiment is described in detail.
The flow chart of the embodiment of a kind of information processing method that Fig. 1 provides for the embodiment of the present application, described method can comprise following step:
101: the first electronic equipments are determined and in video data, are met pre-conditioned key video sequence frame.
This pre-conditioned can according to the features such as the color of video frame content, texture and shape determine, can also according to amount of information determine; Can also determine according to Search Requirement, historical search records etc.
Therefore, key video sequence frame can select frame of video that the features such as color, texture and the shape of video frame content meet certain condition as key video sequence frame.
Or, select frame of video that inclusion information amount is larger as key video sequence frame;
Or, select to mate with Search Requirement, or the frame of video of mating with historical search records is key video sequence frame, for example historical search records shows the video content of historical retrieval and the content of the first Topic relative, and therefore can select video content is that the frame of video of this first theme is key video sequence frame.
Certainly,, as the possible implementation of another kind, key video sequence frame can also select to represent the frame of video of video data main contents.Thereby carry out video frequency searching according to key video sequence frame, can ensure to a certain extent the accuracy of video frequency searching.
Carrying out key video sequence frame while determining, can first video data be carried out to camera lens and cut apart, thereby select key video sequence frame from each camera lens.Make the equal correspondence of each camera lens have crucial frame of video, key video sequence frame can represent the main contents in corresponding camera lens.
What now key video sequence frame can be selected is the frame of video of camera lens main contents of reflection, and it can be a frame or multi-frame video frame.
Same video camera carries out continuously uninterrupted shooting, and the frame sequence of a continuous action on expression time and space is called a camera lens.
The camera lens of video data is cut apart and can be adopted shot boundary detection mode to detect shot boundary, and then video data is cut apart according to camera lens again.
The formation of shot boundary is two results that camera lens switches, and border is because the discontinuous of video content caused, and therefore can determine accordingly shot boundary.
Key video sequence frame can also adopt frame average algorithm to determine, for example can the mean value of the pixel value of its all frame of video will be asked in a camera lens, using the frame of video that approaches most this mean value in a camera lens as key video sequence frame, now in a camera lens, choose a key video sequence frame, this key video sequence frame represents the main contents of a camera lens.
102: the video tab that adds the described key video sequence frame of mark in described video data; Wherein, when the described video data that adds described video tab is obtained and plays by the second electronic equipment, described the second electronic equipment is determined the described key video sequence frame in described video data according to described video tab, and in navigation position corresponding to the frame of key video sequence described in navigation information, export the information of described key video sequence frame, described navigation information is for representing the temporal information of described video data.
Video tab can be encapsulated in video data, transmits as a part for video data.
Navigation information refers in video data playing process, the control information showing at the predeterminated position of broadcast interface.Its temporal information by video data forms.Navigation information is made up of navigation spots, and each navigation spots represents a time point, a corresponding frame frame of video.Therefore the second electronic equipment is determined after key video sequence frame, its position and time etc. in video data can be determined, thereby according to the position in video data and the time of key video sequence frame, can determine its navigation position corresponding in navigation information.
As shown in Figure 1a, a kind of interface display schematic diagram while broadcasting for video data in the embodiment of the present application, in the time that video data is play, export navigation information 100 simultaneously, user can carry out Artificial Control to the broadcasting of video data by navigation information 100, for example, control when video data is play and advance or retreat some frame of video.In video data playing process, in navigation information, also can export the prompting to playing progress rate and/or buffer memory progress, for example in Fig. 1 a, the length of the black filling part of navigation information represent the size of playing progress rate and/or buffer memory progress.
Information 200 at navigation information 100 key video sequence frames is arranged in the navigation position that navigation information is corresponding.
This information can, for key video sequence frame is pointed out, point out user to have key video sequence frame in this navigation position.This information can be label symbol having notable feature etc.
This information can also be for the pointing out of the video content of key video sequence frame, and points out user the video content in this navigation position.This information comprises outside label symbol, can also comprise Word message or image information etc., and Word message can be subject information or the summary info etc. of the video content to key video sequence frame, and image information can be the thumbnail of this video content etc.Wherein, image information can also be dynamic image, and each two field picture of this dynamic image can be the frame of video in the camera lens of key video sequence frame place.
Wherein, in described video data, the video tab of the described key video sequence frame of interpolation mark has multiple possible implementation:
In a kind of possible implementation, specifically encapsulate video label in each key video sequence frame.
Can be to add video tab in the frame originating point information of each key video sequence frame.
Thereby the second electronic equipment gets video data, while decoding, if detect, frame of video is the frame of video that is packaged with video tab, can determine that it is key video sequence frame.
In another kind of possibility implementation, the video tab of specifically selecting key video sequence frame described at least one frame frame of video package identification in described video data, described video tab comprises positional information and/or the temporal information of described key video sequence frame in described video data.
