Description
Technical field
The present invention relates to field of computer technology more particularly to a kind of audio play control methods and multitone display system to splice
Equipment.
Background technology
In daily life, in places such as food and drink hotel, market movie theatre, business halls, it is seen everywhere for information bulletin, pushes away
The large screen terminal presentation facility extensively publicized, i.e. digital signage；And in teaching and office meeting field, it is also often applied to height
Clear large-size screen monitors are display and operating platform, realize the intelligent interaction tablet of human-computer interaction.
, has there is the number that there is multi-screen splicing to form at present in the prior art constantly innovation and development in large-screen technology
Word label or intelligent interaction tablet, these multi-screen devices have multiple independent control systems, can play different letters simultaneously
Breath, meets the needs of more audients.But such as comprising multiple audio playing apparatus in equipment, when playing different audios at the same time,
Different sound can be caused to be superimposed, caused very noisy.
The prior art is all for example there was only one in multi-screen device by manually pre-processing to the processing scheme of this problem
A screen system installs audio playing apparatus, makes that there is the source signal of audio-frequency information to pass through uniquely with audio by manual operation
The screen system of playing device is exported；Or manual control source signal format, while the not homologous signal exported can only have
One source signal has audio-frequency information.These schemes, which all cannot achieve, to be automatically controlled, artificial treatment trouble, and is easy to because of people
Playback error, user experience is caused to decline for error.
Invention content
The technical problem to be solved in the present invention is, proposes that a kind of audio play control method and the splicing of multitone display system are set
