Description
Technical field
The present invention relates to the fields such as captions, the solution broadcasted particularly to the association of a kind of image-text flash.
Background technology
In teletext field, image-text flash refers to the physics literary composition that one group of image sequence preserves through interframe compression
Part, it can realize the dynamic effect of picture and text, have and more use in teletext.The attribute that image-text flash is general includes chi
Very little size and length (i.e. frame number).The broadcast of animation is exactly image sequence decoding and the process broadcasted, and general picture and text system is all
Can realize the broadcast of animation, cutting from beginning to end is broadcasted and circulates the functions such as broadcast.The stunt type carried according to animation itself is not
Be divided into into, stop, go out animation, each type of animation correspond to different broadcast effects, represents animation broadcasted as entered animation
It is maintained in after Biing on screen, goes out animation and represent that animation broadcast is complete.
It is placed the cartoon material in three identical sources on time shaft as shown in Figure 1, is designated as A, B, C animation respectively, often
Individual animation is with different captions stunts, and they achieve the stunt of fading in of animation respectively, ripples stop stunt and linear slide
Go out stunt, therefore A, B, C be belonging respectively to into, stop, go out animation.Material ordering on the time line and position are needed by program
Ask decision, it is assumed that each material access point on the time line is not close to, according to respective stunt type, broadcasting of its reality
Putting effect is:
Animation A broadcasts in the way of fading in the timeline access point of its correspondence, and timeline often walks a frame, and picture and text system broadcasts
The image that one frame is corresponding, until it go out a little, at this moment animation A rests on transfixion on screen；Timeline continues to go ahead,
By the time the access point of animation B, animation A lost efficacy, and animation B starts anew to broadcast each content frame successively with the trick mode of ripples,
Until it go out a little, at this moment animation B rests on transfixion on screen；Timeline continues to go ahead, and has waited until entering of animation C
Point, animation B lost efficacy, and animation C starts anew to broadcast each two field picture content successively in the way of straight line stunt, until going out of it
Point.
There are the following problems for this traditional image-text flash player method: one is when timeline is in the blank between material
Place, because not having effective animation out points the most corresponding, animation remains static, until timeline arrives next animation
, therefore there is still frame, poor visual effect between two animations in the effective coverage of material；Two be the access point of each animation always
The image sequence head frame corresponding from animation file starts playing out, when whole timeline broadcasts the cartoon material in identical source, depending on
Feeling that effect can not be continuous, this can not meet the demand of user.
Summary of the invention
The invention provides the solution that the association of a kind of image-text flash is broadcasted, the cartoon material for identical source is set up altogether
With decoder object, the access point of first animation from time shaft, system from decoder object from the beginning of the first frame of current animation,
It is successively read each frame of current animation, commences play out current animation, to the last the going out a little an of cartoon material, and centre
Material number is unrelated, solves in tradition picture and text system and broadcasts incoherent problem, simultaneously between the cartoon material in identical source
Can need to increase with not limiting cartoon material according to broadcast effect, and give different stunts, solve animation literary composition with being also convenient for
Part on the premise of not affecting broadcast content seriality, the problem arbitrarily increasing different special effects.
Concrete grammar is as follows:
S101: the cartoon material for identical source sets up common decoder object；
S102: image sequence in decoding animation file successively, the animation of these shared decoder objects the most referred to as closes linkage
Draw；
S103: the access point of first animation from time shaft, system from decoder object from the beginning of the first frame of current animation,
It is successively read each frame of current animation, commences play out current animation, to the last the going out a little an of cartoon material；
S104: in the effective coverage of association animation, according to broadcast effect need increase cartoon material, and give difference
Stunt.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, required use in embodiment being described below
Accompanying drawing be briefly described.
Fig. 1 is background of invention time shaft and cartoon material graph of a relation.
Fig. 2 is the flow chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
As in figure 2 it is shown, detailed description of the invention is as follows:
One, cartoon material A, B, C are association animation, i.e. have identical physical file source, and system is that they are set up altogether
With decoder object, decoder object and an animation file be associated, and it is responsible for image sequence in decoding animation file successively, when
When cartoon material makes the picture material being finished last frame, decoder object starts anew to decode picture material again, the most permissible
Ensure no matter cartoon material broadcast length length on the time line is with short, can ensure the seriality of content.
Two, because the access point that the vital stage is first animation of association animation starts, last animation is continued up to
Go out a little, therefore when timeline goes to the access point of cartoon material A, decoder object need read picture numbers be 0, class successively
Push away, until timeline arrive cartoon material C go out a little, at this moment present frame serial number n of decoder object, this value depends on that animation is raw
The length of life phase and the length of animation file itself.Owing to associating the content decoding always continuous print of animation, so n value itself is also
Inessential.This addresses the problem the problem broadcasting discontinuous and blank space frozen frame.
Three, according to the feature of association animation, we the most just can realize animation file is not affecting broadcast content
On the premise of seriality, arbitrarily increase different special effects.As it is shown in figure 1, its effect broadcasted is:
From the beginning of the access point of A material, animation broadcasts with the stunt faded in, reaches when going out of A material, and stunt of fading in is complete
Finishing, the rear shifting animated content of line is constantly updated over time；When timeline arrives the access point of B material, it is special that animation performs ripples
Skill, until B material go out a little, ripples stunt is finished；When timeline arrives the access point of material C, animated content starts to hold
The stunt that row straight line goes out, until C's goes out a little.During whole, animated content keeps constantly updating, and in the different time periods
In complete different special effects, be greatly enriched the application of title cartoon.
The present invention is including, but not limited to embodiments described above, and any those skilled in the art need not pay wound
The property made work just can think of change all should fall into protection scope of the present invention.
