Described title insert 1B is used for, and when carrying out captions and playing output, calls the subtitle file by captions generalized edit module and captions special technology making module making, carries out the broadcasting of captions, specifically can comprise:
Superposition output module 101, for getting frame captions picture from subtitle file, and to superpose with described frame captions picture the video background picture of input and exports.
Father's special technology making submodule 121,
Before submodule 121 makes father's stunt, just caption object should be divided into multiple caption object group, division principle can be, the caption object with identical captions stunt is classified as one group.
Be briefly described captions stunt type and caption object below, the captions stunt in reality mainly comprises:
Distortion stunt, comprises growth, scrolling, stroke as, cracked, distortion etc., only supports two-dimensional primitive;
Path stunt, comprise straight line, linear, wave, spring etc., support two dimension, three-dimensional pel and figure tuple;
Transparent stunt, supports two dimension, three-dimensional pel and figure tuple;
Texture stunt, makes superficial makings convert by specified coordinate, only supports two dimension, three-dimensional pel;
Material stunt, makes surface change by designated parameter the reaction of illumination, only supports three-dimensional pel;
Packaging stunt, the gorgeous stunt that display is accelerated, comprises flame, laser, streamer etc., only supports two-dimensional primitive.
Caption object in reality mainly comprises:
Word pel: word, libretto object;
Roll screen pel: roll screen pel, roll screen file object;
Animation primitive: animation, video file object;
Common pel: all caption object except word, libretto, roll screen, animation primitive, such as, figure tuple.
Such as, when introducing the starting-lineup of Women's World Volleyball Grand Prix China Team, a first out plate object, this plate object has stunt of rolling from bottom to top when entering; When simple solution mentions each team member, each team member's object enters screen from top to bottom, also namely requires that each team member's object adopts when entering stunt of rolling from bottom to top; Further, when concrete certain team member of explanation, require that this team member's object uses color stunt in displaying process; But meanwhile, each team member's object also has the stunt different from other object, such as, use upset, highlight stunt etc.Like this, when dividing into groups, just 6 team member's objects of described plate object and China Team can be divided into two groups: roll from bottom to top stunt group and color stunt group.
In specific implementation, increase group stunt one in the attribute of current subtitle object, namely can divide into groups this alphabetical object.
Be appreciated that, when described caption object is word pel, the production unit of described word graph meta object can be word for word (such as, certain word in team member's name), by word (as team member's name), line by line (as team member's name and height, age information) or overall (such as, the information of all team members).
In upper example, the course of work of submodule 121 can be, for stunt group of rolling from bottom to top, makes stunt of rolling from bottom to top, as father's stunt of described plate object and 5 team member's objects in group.
Sub-special technology making submodule 122,
The function of submodule 122 is the captions stunts for not being grouped in current subtitle object, makes the sub-stunt for this caption object.
Such as, when solution mentions certain team member's object, this object has and highlights stunt, and does not divide into groups for highlighting stunt, so, need submodule 122 to carry out the making of the sub-stunt of this object.
Stunt process submodule 123,
The major function of submodule 123 is the father's stunts to current subtitle object, sub-stunt carries out calculation process.
Be appreciated that when a caption object is in multiple groups, submodule 123 may be used for carrying out superposing the captions target stunt formed for current subtitle object to multiple father's stunt and sub-stunt.Such as, team member's object 1 is in 2 groups: roll from bottom to top stunt group and color stunt group, but, when solution mentions this object, it also has upset stunt, and does not comprise upset stunt group in described caption object group, so, need submodule 122 to carry out the making of the sub-stunt of this object.Visible, the target special effects of team member's object 1 is brought jointly by two father's stunts and a sub-stunt.
Some news program end play Domestic News time, usually using the caption animation shown in Fig. 2 as character background, father's special technology making submodule 121 has made father's stunt for caption object circular arc 201 and 6 circles 202, and its translational speed is S1; Sub-special technology making submodule 122 has made sub-stunt for 6 circle 202 caption object, and its translational speed is S2; And it is some T relative to the delay entered a little of the broadcast time of father's stunt that the broadcast time of sub-stunt enters, and the broadcast time of the two goes out a little identical.
For said circumstances, submodule 123, from the broadcast time of sub-stunt enters, superposes described father's stunt and sub-stunt, such as, according to the plane coordinates of described father's stunt and sub-stunt, can calculate the plane coordinates of target stunt.In upper example, the speed of hypothetical target stunt is S, and the superposition due to father's stunt and sub-stunt forms the target special effects for current subtitle object, therefore has S=S1+S2.
In like manner, be mobile stunt in father's stunt of current subtitle object, and sub-stunt for mobile+upset stunt time, the arithmetic operation of submodule 123 can be, according to the plane coordinates of described father's stunt and the plane+upset coordinate of sub-stunt, calculate the plane+upset coordinate of target stunt.
And when father's stunt of current subtitle object and sub-stunt are upset stunt, the arithmetic operation of submodule 123 can be, for being axial coordinate by the upset Coordinate Conversion of described father's stunt and sub-stunt, then calculates the upset coordinate of target stunt.
