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 device for full video marker of the present invention, as shown in the figure, described device comprises: speech analysis module 10, for obtaining whole video file to be marked, and extracts the voice signal in described video file to be marked; Sound identification module 20, for identifying described audio digital signals, and converts thereof into corresponding letter signal; Control treatment module 30, for being attached to by described letter signal in the video file at described to be marked some place, is shown 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.
