Division points, the function of editing division points, in addition there are division points fine adjustment functions.Fine adjustment function is used for after increasing division points, micro-
Division points position is adjusted, for example, we are in the song for carrying out Liu De China《Providence》Religion is when singing, want division points setting " who lies in,
Mine has more hardships at heart " ending at, but may be because certain reasons cause to be not provided with it is accurate, then can use micro-
Conditioning function is calibrated, and the division points that we choose are finely adjusted, and is moved forward or backward, until user thinks proper
To benefit.So the function being arranged by playback of songs interface, very easily division points can be arranged on desired ground by user
Side.
After obtaining the division points input by user to the song-video in some embodiments, also song-video is divided
The information of point is recorded in corresponding storage device.The corresponding storage device can be removable storage device, can also be
The storage equipment of song-video file.By storing the partitioning site of song-video, woth no need to again in the use of user afterwards
The secondary section for dividing song-video, in further embodiments, user can also delete the division points of song-video.
In some embodiments, teaching pattern may include that pattern is sung in continuous section religion.It is shown in Figure 2, in practice area
Section religion is sung in pattern, by according to the sequence in song-video of section, first plays the original singer of first section, then play first
The accompaniment of section, then the original singer of next section is played, then the accompaniment of next section is played, the original singer until all sections and accompaniment
After all playing, restart the original singer for playing the first section.In further embodiments, in a certain section of device plays
(original singer for playing the section or accompaniment), user, which is also an option that, is switched to the upper section for playing the section or next section,
The original singer of the section after switching is first played after switching, then plays the accompaniment of the section after switching, it is so piecewise according to sector sequence
Play original singer and accompaniment.This method is conducive to user and familiarizes teaching song, and user is made to have impression to each section of song.
In some embodiments, teaching pattern may include that pattern is sung in single section cyclic religion.Mould is sung in the religion of single section cyclic
In formula, the section that will be selected according to user repeats playing original singer or the accompaniment of respective segments, or plays companion again first to play original singer
The mode played repeats playing respective segments.After user selects section, user, which is also an option that, switches to a section or next
Section.
In some embodiments, teaching pattern may include that pattern is sung in self-defined AB division points religion.It is divided in self-defined AB
Point religion is sung in pattern, according to A division points input by user and B division points, will repeat A after entering the religion of AB division points and singing pattern
Section original singer between division points and B division points or accompaniment, or repeat playing A in a manner of first playing original singer and play accompaniment again and draw
Section between branch and B division points.
In the above-described embodiments, user can also be switched to broadcasting vocal accompaniment, or switch from vocal accompaniment is played when playing original singer
To broadcasting original singer.Such as in pattern is sung in the religion of single section cyclic, the original singer of certain currently playing section, user selects switching, then cuts
The vocal accompaniment for playing the section is changed, after playing the vocal accompaniment of the section, then plays the original singer of the section, is so recycled.
Because because being unfamiliar with to song when starting religion song, it is ripe to song progress first pattern can be sung using the religion of continuous section
It knows, user repeats according to the sectional of original singer-vocal accompaniment, listens several times and then hummings that will be slowly in this way.Then user can
Entire song is learnt from the beginning with selecting the single section cyclic religion of enabling to sing pattern, is learnt respectively paragraph by paragraph, until all songs
Tune is all familiar with substantially, it is last because in partial content or song in certain sections partial content may more difficult grasp, use
Family can enable AB division points religion sing pattern, this pattern can arbitrarily set AB division points, to AB division points refer within area
Domain carries out religion and sings, and the part for being easy to the song grasped to hardly possible in this way repeats to practice, and achievees the purpose that facilitate teaching.In this way, with
Family pass through more than several modes combination, it should one song of grasp that can be quickly.
In some embodiments, after obtaining song-video, also video file is checked, the basic principle of detection
Whether the time interval for being to look at the adjacent key frame of song meets religion and sings requirement, due to song key frame density (adjacent key
The time interval of frame) meet to teach in 1s songs below and sings requirement.For adjacent key frame density in the song of 1s or more, need to lead to
Crossing video recodification tool can recode to song-video, so that its key frame density is met religion and sing demand.
Transcoding key frame video frame is divided into key frame (I frames) and non-key frame (P frames and B frames), is mainly used for interframe compression.
P frames need to refer to front associated frame information when being forward predictive coded frame, i.e. P frame decodings could decode；B frames are bi-directional predicted
Coded frame, when decoding, had not only needed to refer to the existing frame in front but also had needed to refer to frame to be decoded below；P frames and B frames are all based on I
Frame carrys out compressed data.
Video frame after transmitting a frame key frame, then is transmitted multiframe non-key frame, is then transmitted again latter in transmission process
Frame key frame, is recycled with this, causes to be spaced multiframe non-key frame between two adjacent key frames.According to the frame per second of transmission of video, that is, every
The frame number for the non-key frame being spaced between the frame number and two adjacent key frames of second display, it may be determined that between two adjacent key frames
Time interval.In order to teach redirecting accurately, for the video of frame per second 25-30fps, it is desirable that be spaced not between adjacent key frame when song
More than 30 frame non-key frames.The reason of above-mentioned selection is that video frame rate is typically 25-30fps, between selecting between adjacent key frame
Every 30 frame non-key frames, the time interval 1 second or so through the adjacent key frame that converts.It is therefore to be understood that if frame per second is more than
60fps then preferably requires the non-key frame being spaced between adjacent key frame to be not more than 60 frames.When between adjacent key frame
Between be spaced in 1s or more, then need by video recodification tool, such as FFmpeg, MediaCoder etc. to song-video carry out weight
Coding makes its key frame density meet religion and sings demand.
In some embodiments, for a certain specific song, if song is divided into first segment 0s-17s, the second section
Then song division points information preservation is by 18s to 37s, third section 38s to 60s ...：Node 1-17s, node 2-37s, node 3-
60s ..., wherein 1,2,3 represent node index, and subsequent 17,37,60 are the corresponding song temporal informations of node, with this
Kind mode be saved in file SongInfo.ini.In other examples, song division points information may be to preserve
For：Node 1-18s, node 2-38s, node 3-61s ..., but it is understood that, these variants are substantially all equivalent
's.In some embodiments, this method is the division points information preserved in this way using song and song files SongInfo.ini
's：Here it is exactly that the song nodal information preserved above is read by code, specifically used is exactly that religion detects when singing playback of songs
Whether it is played at the timing node of song files record, sings pattern according to current religion if being played to and located accordingly
Reason, for example, song is divided into first segment 0s to 17s, second saves 18s to 37s, third section 38s to 60s ..., and corresponding song is drawn
Branch information preservation is：Node 1-17s, node 2s-37s, node 3s-60s ...；For the song of above-mentioned division, read (simultaneously
Parsing) after song division points information, if being in loop play pattern, the original singer for first playing 0s-17s sections plays 0s-17s again
Accompaniment, the original singer for then proceeding to play 0s-17s sections plays the accompaniment of 0s-17s again, until user be switched to practice other
Section；If singing pattern in the religion of continuous section：The original singer for then first playing 0s-17s sections plays the accompaniment of 0s-17s again, then jumps again
It goes at the 18s of original singer, plays the original singer of 18s-27s, redirect and play original of the accompaniment of 18s-27s until finishing entire song
It joins in the chorus accompaniment；If singing pattern in single section cyclic religion：(such as it is currently original singer, then just according to current former track of accompanying
Always original singer) loop play 1-17s section videos, it is desirable to play next section need manually triggering click screen on " under
One section " button.If singing pattern in the religion of self-defined AB division points：According to A division points input by user and B division points, repeats A and draw
