The objective of the invention is to the defective at existing caption editing system, a kind of collision detection method based on captions under the program of zone division is provided, to realize the collision detection function of captions under the program.
Technical scheme of the present invention is as follows: a kind of collision detection method based on captions under the program of zone division comprises the steps:
(1) according to captions in the position that video screen shows, screen area is divided the corresponding different caption editing template in each zone;
(2) determine that needing the affiliated area of captions under the interpolation program is regionId;
(3) all captions in traversal this program, if having other captions and required interpolation captions time to overlap, and regionId is identical, then points out subtitle collision;
(4) traversal timing captions, if having regularly captions and required interpolation captions time to overlap, and regionId is identical, then points out subtitle collision.
Further, aforesaid collision detection method based on captions under the program of zone division, the screen area of dividing in the step (1) comprises: rod-pulling type information area, guide information area, advertising message zone, roll titles information area, TV play information zone.
Further, aforesaid collision detection method based on captions under the program of zone division, determine in step (3) and the step (4) that the method whether different captions time overlap is as follows: the time started of establishing captions 1 is that startTime1, concluding time are endTime1, the time started of captions 2 is that startTime2, concluding time are endTime2, and the time, more early numerical value was more little, and the time that meets following any one situation overlaps:
(1) startTime1＜startTime2, and endTime1〉startTime2;
(2) startTime1＜endTime2, and endTime1〉endTime2;
(3) startTime1〉startTime2, and endTime1＜endTime2.
Beneficial effect of the present invention is as follows: the present invention according to captions in position that video screen shows, screen area is divided, according to the zone subtitle template is divided and managed, formed the corresponding different zone of different channel, and the structure of the corresponding different templates in zone; When captions are edited, select the zone earlier and then select a template under the zone to edit, detect by the testing conditions the set subtitle collision to the same area, avoided the overlapping demonstration of captions, improved the fail safe that caption editing and program broadcast.
