Embodiment 2
The schematic flow sheet of method second embodiment of video segment is intercepted in the embodiment of the present invention as indicated at 3.
Step 21, mobile terminal receive the interception initiation command that user submits, and mark and remember in current video broadcast interface
To intercept starting point, i.e. locus intercepting starting point, while recording the broadcasting attribute of interception starting point；
The present invention will intercept the broadcasting attribute record of starting point, heretofore described broadcasting attribute tool by writing function
Body is that, corresponding to the position and currently playing mode represented on former video with time point, the currently playing mode includes broadcasting
Put, F.F., slow-motion, rewind and move back slowly.
Wherein, user submits interception order to pass through " starting interception " pre-set button in video playback interface and submits interception life
Order.Mobile terminal receives the interception order of user's triggering, in current video broadcast interface mark, and the presentation mode of the mark can be with
For flicker intercepts symbol on any corner on currently playing interface；Or display interception symbol, and interception time is shown, it is similar
In the existing video capture function of mobile phone, symbol is revealed as " interception 00 when citing interception starts:00”.
And in another embodiment, of the invention can carry out video intercepting in the pattern of " rewind " or " moving back slowly ",
For the video intercepting of this retroversion type, the equally interception symbol when starting interception is " interception 00:00 ", cut with falling back

And this setting meaning for playing operating point is more：(1) interception video person intuitively can be carried out in broadcasting
The adjustment of efficiency is intercepted, such as operator thinks that present segment must intercept and be not desired to lose time, then can take fast-forward mode；And for example
When operator is played to some interface, think that the interface need not be intercepted, then can be retreated using rewind or the slow pattern of moving back,
While such inverse operations, corresponding reduction occurs for the time shown in interception mark, and such as normal reverse is played 30s, then shown
The time shown accordingly reduces 30s；Played even if continuation of going back on one's word after operator retreats moves ahead, can switch to broadcasting, F.F. or slow
The play mode entered, and intercept the time shown in mark is then increased by above-mentioned rule.(2) interception video person can work as playing
Front interface using rewind or it is slow move back time for being shown in the reverse interception that pattern carries out video, interception mark according to video it is actual when
It is long to be shown.
According to above-mentioned rule, randomness and the flexibility of interception video are realized；Locus intercepting is covered along track is played,
When changing play operation dot command, system records the broadcasting attribute of each play operation point.
In step 23, broadcasting video, the terminal played in last play operation point, mobile terminal receives user and submitted
Interception terminate order, be interception terminating point in currently playing Interface Mark, stop interception action, record interception terminating point is broadcast
Put attribute, and tentatively generation interception video segment；
Need explanation when, the step generation interception video segment be preliminary segment, be to be regarded without the interception of reparation
Frequency fragment, the video segment can be the video segment that lower interception is played according to normal play mode, and this video segment is
It need not be repaired；Can also include broadcasting, F.F., slow-motion, rewind or move back middle two or more play mode slowly and broadcast
The video segment of interception is put down, and this kind of video segment is then to need to be repaired.
After step 24, interception action stop, locus intercepting is repaired, the final interception video segment of generation；
Specifically include following two contents：
1st, determine that interception terminates section according to the broadcasting attribute of record, judge that interception terminates the type of gesture of section, and correspondingly enter
Row is repaired.
Wherein it is determined that the method that interception terminates section is：By the starting point to the end of last play operation point of record it
Between broadcasting track be determined as interception terminate section.
If the track that interception terminates section is single-track, it is determined that it is video intercepting terminal that interception, which terminates section final on trajectory, cut
The broadcasting track for taking track to be covered is the video segment of interception；If the track that interception terminates corresponding to section is dual trace
(it is 2 to refer to track number) or multi-trace (referring to track number more than 2), it is determined that it is video intercepting terminal that interception, which terminates section final on trajectory, will
First paragraph track terminates section trajectory extraction with interception in dual trace or multi-trace, and by the play position of first paragraph track and interception
The play position for terminating section track is compared, and carries out determining whether in target interception video segment with reference to interception starting point
Hold, if then cutting off, obtain the target video fragment to be intercepted.Specific determination methods are as follows：
When the track that the interception terminates section is single-track, including：
(1) play position of interception starting point is before the play position of interception terminating point, and interception terminates that section is last broadcasts
It is broadcasting, F.F. or slow-motion to put operational order, then the path that interception termination section broadcasting track is covered is the video of interception
Fragment.Shown in Fig. 3 first paragraphs, reproduction times (i.e. play position) 02 of the starting point A of fragment in former broadcasting video is intercepted:00
In interception terminating point B play position 08:Before 32, and it is preceding progressive die to intercept the last play operation orders of termination section a
Formula (broadcasting, F.F. or slow-motion)；So, the path that interception termination section broadcasting track is covered is the video segment of interception.
(2) play position of interception starting point is after the play position of interception terminating point, and interception terminates that section is last broadcasts
Operational order is put for rewind or is moved back slowly, then the path that broadcasting track is covered is the video segment of interception.Fig. 3 second segments institute

Take the play position for terminating section a1 to compare, will be greater than terminating point play position 09:30 video content is deleted；If first paragraph track
The play position that an and interception terminate section a1 tracks has overlapping, then cuts off the lap intercepted in termination section a1 tracks.
(2) play position of interception starting point is after the play position of interception terminating point, except first paragraph rail in multi-trace
Mark is cut off with intercepting the track terminated outside section track, and first paragraph track and interception termination section track play out position and compared, will
Play position is less than the video content excision that interception terminates segment endpoint play position, wherein, if first paragraph track and interception are terminated
The play position of section track has overlapping, then interception terminates lap in section track and cut off.
Shown in Fig. 5 (third and fourth section), the starting point A of fragment play position 08 is intercepted:00 broadcasting in interception terminating point B
Put position 02:Behind 14, interception terminate the last play operation order of section an for forward mode (in figure shown in the 3rd section) or
Person's " fall back " mode" (in figure shown in the 4th section), then, on the interception video segment tentatively generated, except first paragraph track an and cut
Take termination section a1 to retain outer, other tracks a2, a3... are cut off, and first paragraph track an play position and interception are terminated
Section a1 play position compares, and will be less than terminating point play position 02:14 video content is deleted, if first paragraph track an and cutting
Take the play position for terminating section a1 tracks to have overlapping, then will intercept the lap excision terminated in section a1 tracks.
2nd, when having more than two overlapping tracks in the video intercepting fragment, reparation is deleted in progress.
Detect the interception video segment track tentatively generated：There are more than two overlapping tracks in the video intercepting fragment
When, then retain first paragraph overlapping tracks and final stage overlapping tracks, remaining excision；By first paragraph overlapping tracks and final stage
Overlapping tracks play out position and compared, if any overlapping, then lap excision in final stage overlapping tracks, and retain
First paragraph overlapping tracks splice with final stage overlapping tracks incision.
