Video sequence generally includes a plurality of independently scenes, and a scene can be defined as a continuous incident or one group of continuous action.The content of scene comprises captions, file video, audio frequency, outside straight-through video, animation, clock (simulation, numeral), scrolling information, picture etc.Transition takes place between two scenes be called the scene switching.Video scene switches and to comprise following several types: the sudden change scene is switched, melts and is fade-in fade-out etc.It is exactly at a time that the sudden change scene is switched, and next scene directly covers a last scene.Melt is exactly that two scenes realize level and smooth transition according to certain trick mode.Being fade-in fade-out also claims " fade in and fade out ", and a back picture manifests gradually, and it is clear fully to arrive at last, and the beginning of this scene claims " fading in ", the beginning of a scene of expression; Previous picture conceals gradually until complete obiteration, claims " fading out " end of a scene of expression; The rhythm that fades in, fades out is releived, and can produce a kind of complete paragraph sense with visual intermittence.
A scene can comprise a lot of zones, and can there be function and the action of oneself in each zone.For example: in a multizone scene, video area, live district and 3 zones of subtitle region are arranged, for one of them regional subtitle region, need continuous lastest imformation to satisfy spectators' needs, this just needs independent subtitle region is constantly switched.Film titler shows spectators according to the message queue that edits with message, need intercut or original message need revise the time as new message, film titler deals with very difficult or can't handle, but also can cause deadlock to wait unsafe condition, and stability and fail safe are all very poor.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art:
In the prior art, use a film titler, can't realize the synchronous of scene areas switching, make scene broadcast zone meeting generation broadcast mistake when carrying out the zone switching, picture can get muddled, discontinuous broadcast, nor can be very smooth.
Summary of the invention
The invention provides the synchro system that a kind of scene areas in caption machine switches, in the message queue in order to dynamic increase, change, deletion film titler.
For achieving the above object, the present invention proposes the synchro system that a kind of scene areas in caption machine switches, and comprising:
Film titler is used for dynamic edit messages formation, plays the message queue that edits, and message is sent to display device;
Display device is used for message is showed the user.
Described film titler also comprises:
Broadcast engine, be used for dynamic change, increase, deletion message queue, for each unit that broadcasts in the engine provides software instruction;
Broadcast the unit, be used to play message queue, and message is sent to display device.
