Abstract
This invention puts forward a video unit of quick advance and retreat and quick browsing based on contents, which presents the time interval for each step video span by the time points corresponding to video key frames to reduce redundancy of screen display so as to realize quick forward and retreat of the video, in which, users can localize their concerned video time periods quickly, conveniently and accurately, and key frame picture set provides a path for understanding video contents quickly.
Description
Technical field
The present invention a kind ofly positions video according to video content, realizes a kind of method and the video playback apparatus of video fast forward fast reverse play.
Background technology
In video display process, people usually need to begin to watch from its certain particular video frequency scene of being concerned about, by the F.F. or the rewind down mode of video, can help people to find this specific scene rapidly.Fast forwarding and fast rewinding method commonly used is, multiple according to normal playback speed, realize the fast forwarding and fast rewinding of video playback, its principle is by pre-determined frame period with the later video of decoding, take on screen, to show a two field picture (this image may be defined as and shows key frame) every several frames, reduce video and show the time, realize the fast advance and retreat of video.The maximum characteristics of this method are to implement simply, but performance is not enough on the comprehensive rapidity of video fast forward rewind down, and are difficult to realize F.F. or rewind down by once, are accurately positioned in certain special scenes.
Original video data is non-structured, and one section video can be divided into several scenes, and each scene comprises one or more camera lenses, and each camera lens is made up of a series of continuous recording picture frames again.Generally speaking, the difference of each two field picture is from continuous angle in the same camera lens, and difference is less, have great redundancy in the reflection, and differ greatly between the frame of different camera lenses, so generally speaking the content of two different camera lens reflections is different.Key frame is a kind of comprehensive description to camera lens, and it reflects the main contents of a camera lens usually, and generally speaking, key frame can be one, also can be the set of a plurality of frames.
Conventional method, because what take is that 2 multiples, 4 multiples are realized fast forwarding and fast rewinding to limited patterns such as 32 multiples, at multiple hour, speed is slower, it is more accurate to locate; When multiple was big, one time fast forwarding and fast rewinding speed was fast, but accurately the location may need the front and back of several times to advance and retreat, and comprehensive locating speed is unhappy.
Take the key frame of content-based extraction to realize the fast forwarding and fast rewinding of video, be to realize fully according to the key content in the video, this method is in fast advance and retreat is play, main contents with video serve as to carry out at interval, in this course, can be by the key frame of continuous display video, the current searching position of prompting user.This method is in the fast advance and retreat process, and the redundancy that key frame of video shows is little, thereby can be than the special scenes of the quicker search video more accurately of conventional method.
Summary of the invention
The objective of the invention is to play a kind of mechanism that provides, for the quick retrieval of video provides a kind of new method and video playback apparatus for the fast advance and retreat of video.
The present invention includes the content of the following aspects: (a) from the pairing time point of key frame, definition fast forwarding and fast rewinding step-length, and tabulation is broadcast in formation soon; (b) with key frame as display frame, for the user provides Search Results intuitively; (c) fast forwarding and fast rewinding mechanism.
Content (a) comprising: the time point of (a1) determining key frame; (a2) the fast advance and retreat step-length is determined; (a3) quick playlist; (a4) formation of key frame atlas.
The key frame of content (b) shows and can show by the image that following two aspects provide: (b1) show key frame images from decoded video; (b2) concentrate the extraction image to show from (a4) key frame images.
Content (c) comprising: (c1) according to pre-determined key frame time point, on the basis of video decode, show key frame one by one on screen, realize the fast advance and retreat of describing by the content key frame images; (c2) show key frame images collection in (a4) one by one, search certain special scenes after, begin normal broadcast by this scene or the pairing time point of camera lens key frame; (c3) on the basis of video decode, the fast method of the automatic extraction by key frame extracts key frame, and shows key frame, realizes the fast advance and retreat of video.

Embodiment
Principal feature of the present invention is exactly to utilize the description of video main contents----key frame, reduces the redundance that image shows in the fast advance and retreat, improves the speed and the precision of video contents search.
Key frame is a kind of form of expression that video content is described, and key frame can be by similarity analysis, one or several the representative image that extracts automatically from a camera lens; It can be the shot boundary frame that utilizes the camera lens switching detection method to extract automatically; It also can be the key frame that hand picking is come out.Generally speaking, the description of video content is explained by key frame, and is more directly perceived, more accurate, than text description horn of plenty more.
Mode one: the fast advance and retreat mode that from decoded video, in screen, shows this key frame according to the key frame time point
By each key frame time corresponding point, determine the time interval of fast advance and retreat, this is spaced apart the function of key frame time point, and can form the demonstration step-length table of a fast advance and retreat thus, show according to this, in decoded video, find key frame one by one, and in screen, show this key frame, realize the fast advance and retreat of video playback.
Mode two: concentrate the fast advance and retreat mode that shows key frame one by one from prior storage key frame images
Utilize the time interval table of good key frame images collection of storage in advance and fast advance and retreat, in screen, show this key frame images collection one by one, when the user finds its needed crucial camera lens or crucial scene, the time point that can provide according to key frame, begin from this key frame by normal broadcasting speed, appreciate or edit video content.
Mode three: utilize real-time extraction method of key frame to extract key frame and realize the mode of video fast advance and retreat
This mode has been utilized crucial super real time extracting method, extraction is based on the key frame of video content, in the super real time extracting method, the interval time that the computing cost that compares frame by frame shows when being less than the video normal play frame by frame, thereby can be when reducing the demonstration redundance, can with than normal playback speed faster mode extract key frame automatically, thereby realize the fast advance and retreat of video.This method need not to determine in advance the key frame time point or the key frame images collection of video, possesses better practicality.
