Digital video data and auditory digital data are delivered to video by the 4th step, separate storage respectively respectively by control system
Data storage and audio data memory；
5th step, generates independent time control information, first by the video data in video data memory with each frame picture
Video independent time axle is formed for a time point, the voice data in audio data memory is formed with the millisecond unit interval
Audio independent time axle；Independent time axle control system is then set up, while its time point synchronization video of video independent time axle
Independent time axle and audio independent time axle；
6th step, generation video and audio control information, it is a certain when triggering by independent time axle control system timing time point
After preset time point, its extract current video one frame frame picture feature or extract successive frame picture global motion information and
Local pose information, is converted into video control information；Converted by the frequency values, range value, pitch analysis that extract audio sound
For audio control information；
7th step, foundation, which is called, independently intercuts database, passes through independent time control information, and video and/or audio control letter
Data in database are independently intercutted in breath triggering.
As preferred embodiment, the data of independently intercutting in database are digital video data and/or audio number
Digital data.
As preferred embodiment, the database that independently intercuts is provided with more new interface.
As preferred embodiment, the control system is additionally provided with information gathering response system.
As preferred embodiment, its method of described information collection response system is as follows：Responded by information gathering and be
System gathered data, and data are delivered into control system, control system control, which is called, independently intercuts data in database.
As preferred embodiment, described information collection its gathered data of response system is believed with generation independent time control
Breath and/or the control information binding of generation video/audio.
As preferred embodiment, described information collection response system includes environment information acquisition equipment and attitude information
Collecting device.
As preferred embodiment, described information collection response system also includes voice capture device and physiologic information is adopted
Collect equipment.
The present invention compared with prior art, Digital Media preparation method of the invention, by independent time control information,
And the triggering of video and/or audio control information is interactive, interactive information can carry out later stage modification, and interaction solutions are diversified, and it can
Individually interactive control is realized, the interactive control of binding is also can be blended, it is strong using flexibility, independently it can be set according to scene application
Put.
