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 method for synchronous 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 method for synchronous that a kind of scene areas in caption machine switches, and comprising:
New message queue changes original message queues dynamically by the user, proposes single broadcast of broadcasting the zone is required to form;
Described new message queue is sent to the broadcast engine by film titler;
Described new message queue is handled dynamically by described broadcast engine, the zone that described broadcast engine is modified according to the contents processing of message queue, and require the zone outside the change zone to realize broadcasting synchronously with the zone that is modified;
When described user changed original message queues dynamically, described user increased, deletes and change original message queues dynamically;
Described new message queue by described broadcast engine dynamic process after, described broadcast engine sends to described film titler with described new message queue;
Message queue in the described film titler shows the user by display device;
Described broadcast engine sends a synch command and requires zone and the described zone that is modified except the described zone that is modified synchronous.
Compared with prior art, the present invention has the following advantages:
Use a film titler, can realize the synchronism that scene areas switches, make scene carry out the broadcast that the zone can be orderly when switching, picture smoothness and correct.The broadcast mode is various and flexible, a plurality of zones can alternately superpose, the collaborative broadcast, broadcasting engine does not need to quit work when the dynamic process message queue, handle synchronously but also can carry out each zone easily, guaranteed the fluency that broadcasts, and strengthened flexibility, stability, the fail safe used, can deal with the broadcast requirement of burst.
