Although, have caching technology in prior art, can last play time point, and upper once play time be automatically found last time broadcast point carry out continuation play, but this technology is only confined on same computer, if the computer of study next time is different, just not all right.Also has a kind of technology, utilize time point exactly, key in the time point play last time, allow video jump to this time point play, but, people can not deliberately go when having learnt to write down this time point often, if the time is too of a specified duration, also easily forgetting, in any case for learner, is all very inconvenient.
Therefore, the learner how to make, when carrying out video study, can find the last video time point do not learnt fast, carries out to facilitate it problem that video study just becomes the art reception solution.
Summary of the invention
In view of the above, the object of the present invention is to provide a kind of method for full video marker, the problem once learnt a little cannot be found fast for solving in prior art when repeatedly learning a video.
For achieving the above object and other relevant objects, the invention provides following technical scheme:
For a method for full video marker, described method comprises step: 1) obtain whole video file to be marked, and extracts the voice signal in this video file to be marked; 2) identify described audio digital signals, and convert thereof into corresponding letter signal; 3) described letter signal is attached in the video file at described to be marked some place, for during the described video file of broadcasting, described letter signal is shown in described video clip or outside video clip.
Preferably, in the scheme of the above-mentioned method for full video marker, described step 2) and step 3) between also comprise step: described voice signal is changed into audio digital signals.
Preferably, in the scheme of the above-mentioned method for full video marker, described step 3) in additionally provide the method that letter signal is corrected, specifically comprise step: described letter signal is given preview display, and judge whether there is mess code or bad code in Word message corresponding to described letter signal: if so, then generate one for the interim Word message editor correcting described Word message; If not, then described Word message is preserved.
Preferably, in the scheme of the above-mentioned method for full video marker, in step 2) in, utilize speech text switching software to realize.
As mentioned above, the present invention has following beneficial effect: the present invention broadcasts video by treating or carries out full video marker or the mark that sets up an office broadcasting video, for video viewers provides the more convenient and preview effect of image, one is convenient to find fast the video playback point wanting to learn, and avoids in prior art the situation needing to keep track of time a little or can only carry out on same computer to remember the complex operations such as broadcasting.
Accompanying drawing explanation
In order to be illustrated more clearly in the scheme in the embodiment of the present invention, be briefly described to describing the required accompanying drawing used in specific embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those skilled in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on embodiments of the invention, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of protection of the invention.
In real process, we need to carry out many places mark to video, or learner needs just to know in advance the Word message under each progress point, so that carry out selectivity to play study.So can unnecessaryly carry out broadcasting mark, full video marker can be carried out to whole video file aforehand.
See Fig. 1, show the flow chart of a kind of method for full video marker of the present invention, concrete scheme is as follows: said method comprising the steps of:
Step S10, obtains whole video file to be marked, and extracts the voice signal in described video file to be marked;
Step S30, identifies described audio digital signals, and converts thereof into corresponding letter signal;
Step S50, is attached in the video file at described to be marked some place by described letter signal, shown by described letter signal for during the described video file of broadcasting in described video clip or outside video clip.
Adopt above-mentioned this scheme to obtain video marker, it is a kind of mark in full, so it uses when video and can play the video file after having marked, this is that we only need mobile progress bar or mouse to click relevant video progress, just can see the Word message under this progress bar or corresponding under mouse point, this does not realize for those learner having seen video, or want selectivity to watch the learner of video, be a kind of convenient selection, thus it also avoid the situation of carrying out blindly screening.
Particularly, in above-mentioned steps S10, mainly carrying out voice signal extraction to whole video, certainly, can also be that the video carrying out playing carries out voice signal extraction and convert thereof into corresponding Word message being attached in described video file according to the actual needs.Such as, can being when being played to the position needing mark, carrying out time-outs broadcasting, and utilize mouse to carry out point to be marked choose action; Also can be pull progress bar to choose to carry out dragging artificially, to find the point to be marked needing mark.Choose other point to be marked with this, thus realize video get mark ready.
Further, in step s 30, speech text switching software can be utilized to carry out speech conversion identification to voice signal, thus convert thereof into our visual form.Should be appreciated that in above-mentioned steps S30, above-mentioned speech text conversion identification software, this is the technology of comparative maturity in prior art, just repeats no more here for a person skilled in the art.
Further, between step S30 and step S10, also comprise step: described voice signal is changed into audio digital signals.If that is to say and passing through to resolve above-mentioned video, the voice signal obtained is if not digital signal, and so we need to convert thereof into audio digital signals, identifies it for speech text switching software.Should be appreciated that if the voice signal parsed from video file is digital signal, then do not need to carry out digital-to-analogue conversion again.
Finally, in step s 50, by letter signal being added in described video file, thus the display of markup information is synchronously realized when playing video file, certainly, it may be displayed in video clip, also can be presented in the window outside displaying video interface, and along with the broadcasting of video file, realize the Word message of display corresponding to it.
Further, carrying out before markup information completes mark, present invention also offers the method corrected letter signal, specifically comprising step:
Described letter signal is given preview display, and judges whether there is mess code in described Word message:
If so, one is then generated for the interim Word message editor correcting Word message;
If not, then described Word message is preserved.
In sum, the present invention broadcasts video by treating or carries out full video marker or the mark that sets up an office broadcasting video, for video viewers provides the more convenient and preview effect of image, avoid in prior art the situation needing to keep track of time a little or can only carry out on same computer to remember the complex operations such as broadcasting.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
