No matter be main control system 10 play multimedia file voluntarily, or external equipment is at play multimedia file, after multimedia file starts broadcasting, then main control system 10 obtains the visual effect data set corresponding with played multimedia file.
Above-mentioned visual effect data set, both can be stored in main control system 10, also can be stored in cloud server system.
Can comprise multiple visual effect label in visual effect data set, each visual effect label comprises time setting data and special efficacy setting data.The effective time of the visual effect label that time setting data setting is corresponding is interval, and special efficacy setting data is for setting the mode and other parameters that generate visual effect.
Be understandable that, visual effect label herein refers to time setting data and special efficacy setting data relevance in logic, but and do not mean that concrete data structure and the storage organization of visual effect label, namely the time setting data of same visual effect label and special efficacy setting data are not limited to preserve in the lump.
Namely the storage mode of special efficacy setting data collection can be deposit in the form of a file, also can be store in a database.Special efficacy setting data collection be in advance by artificial or automated programming system be every song customize generate.
If each visual effect label is used for expression beat, so, in a concrete execution mode, visual effect data set such as can be as follows:
[00:00.00] special efficacy setting data 1
[00:24.88] special efficacy setting data 2
[01:27.05] special efficacy setting data 3
[02:30.39] special efficacy setting data 4
……
Each time setting data wherein, such as [00:24.88], be the starting time of the visual effect of a beat, described visual effect naturally terminates after finishing.
If contain the visual effect of multiple beat in a visual effect label or contain static visual effect, so in a concrete execution mode, visual effect data set such as can be as follows:
[00:00.00] special efficacy setting data 1
[00:24.88] special efficacy setting data 2
[01:27.05] special efficacy setting data 3
[02:30.39] special efficacy setting data 4
……
For the special efficacy setting data in this kind of form, can be form a time interval by two adjacent start times, such as, the time interval that [00:00.00]-[00:24.88] is formed be that the effective time of special efficacy setting data 1 is interval.
Be understandable that, the data format of visual effect label is not limited to this, and time setting data also can comprise more information, such as, directly specify out time interval, as follows:
[00:00.00-00:23.86] special efficacy setting data 1
[00:24.88-01:00.90] special efficacy setting data 2
[01:27.05-03:29.00] special efficacy setting data 3
[03:30.39-05:38.86] special efficacy setting data 4
In square brackets, first time is the time started, and then a time is the end time.By this kind of mode, can define discontinuous time interval, its adaptability is more flexible than the mode only including the time started.In the case, all any visual effect can not be triggered at all time intervals outer (time such as at 01:10.00).
In addition, can also be add that time span is interval to the effective time defining each visual effect label the employing time started, can be as follows:
[00:00.00,00:55.00] special efficacy setting data 1
[00:24.00,01:03.00] special efficacy setting data 2
[01:28.00,03:02.00] special efficacy setting data 3
[04:30.00,08:08.00] special efficacy setting data 4
As can be seen from the definition of above-mentioned data, there is overlap in interval effective time of the visual effect that special efficacy setting data 1 is corresponding with special efficacy setting data 2, and therefore, in the present embodiment, two different visual effects can deposit in the interval at the same time.
Further, correspondence is interval at the same time, also can there is multiple visual effect, the visual effect of this multiple visual effect identical type, such as multiple lamp light specific effect, or multiple video superimpose special efficacy, also can be multiple dissimilar visual effect, such as, both comprise lamp light specific effect, also comprise special video effect.Now, special efficacy setting data collection such as can be as follows:
[00:00.00,00:55.00] special efficacy setting data 1-1, special efficacy setting data 1-2
[00:24.00,01:03.00] special efficacy setting data 2
[01:28.00,03:02.00] special efficacy setting data 3
[04:30.00,01:08.00] special efficacy setting data 4-1, special efficacy setting data 4-2.
Be understandable that, the setting means of above-mentioned first visual effect label is equivalent to under type:
[00:00.00,00:55.00] special efficacy setting data 1-1
[00:00.00,00:55.00] special efficacy setting data 1-2
That is, the visual effect label comprising multiple special efficacy is split into interval identical visual effect label multiple effective time.
In above each cited embodiment, when the characteristic manner of time is: point: second, but the present invention is not limited to adopt in this way, such as, can directly adopt the arbitrary unit such as number of seconds, millisecond number, the number of minutes to characterize.For time started 00:24.00, being converted into number of seconds is then 1440, and being converted into millisecond number is 1440000, directly represents with the number of minutes and is 24.The time data recorded in time setting data can also be to time value carry out various can the result of inverse operation, even can be encrypted computing.For above-mentioned number of seconds 1440, such as, it can be obtained 720 divided by 2.What that is store in time setting data is 720, but in fact its express be 1440 seconds.Be understandable that, after this computing, interval to the effective time calculating certain visual effect label, need to carry out reverse operation and obtain actual time interval.
Be understandable that, no matter through which kind of process, its essence remains by defining a start time or a time interval in visual effect label, and therefore, these all modes all should be included in the scope of above-mentioned time setting data.
Special efficacy setting data can be the source file of video, animation, picture, word.
Special efficacy setting data can be for setting the mode and other parameters that generate visual effect.Visual effect herein can comprise static special efficacy and dynamic special efficacy.Static special efficacy such as can comprise the constant special efficacy of the contents such as light color, lamplight brightness, display pattern, display word.Dynamic special efficacy such as comprises various animation, such as colour switching, brightness change, pattern change, word change, animation or its combination, and dynamic special efficacy can a corresponding beat, also can corresponding a series of continuous print beat.Above-mentioned animation effect, such as, can be included on vocal accompaniment multimedia video key frame and superpose animation effect, such as show full frame fresh flower, rain, snow, heart-shaped cake etc.Special efficacy setting data can also be the data of the extended formatting for obtaining visual effect, such as, and the identifier of visual effect resource file.And visual effect resource file herein can be pre-stored in the memory that is connected with main control system 10, or be stored in cloud server.Main control system 10 can read the visual effect resource file corresponding with the identifier of visual effect resource file in memory, or initiates network request, downloads visual effect resource file from cloud server.
Preferably, the visual effect set by special efficacy setting data is relevant to the beat of music, and the timing node of beat is controlled by above-mentioned time setting data.In general, visual effect set by special efficacy setting data, for each beat in the middle of music, visual effect preferably can export an obvious visual effect change, and amplitude, speed, scope etc. the parameter of visual effect change should be to the feature of beat (by audio frequency parameter as volume, frequency are carried out analysis and obtained) relevant.Therefore, just can be reflected the change of music by visual effect, make music except sound, can also by the mode of visual effect to people with abundanter stimulation.In other words, the object of the visual effect in the present embodiment is by visual for the beat of music, the beat sense of strengthening music.
In the pressure sensitivity visual effect system of the present embodiment, also synchronous according to pressure-sensing assembly 15 pressure data of main control system 10 adjusts the visual effect that visual effect device 11 exports immediately.
In a concrete execution mode, main control system 10 according to the special effect parameters of the rule prestored from pressure data computation vision special efficacy, and changes Current vision special efficacy signal according to described special effect parameters.Such as, pressure data can be mapped with the brightness of visual effect.That is, the mapping function F (θ) between build-up pressure data θ and visual effect brightness.So, corresponding to the pressure data of each cycle synchronisation of pressure-sensing assembly 15, main control system 10 adjusts the brightness of Current vision special efficacy signal immediately.Above-mentioned mapping function is preferably a continuous function, thus make described special effect parameters along with the change of hand-held pressure assembly 11 intensity of pressure consecutive variations.
Be understandable that, the parameter that can change is not limited to brightness, arbitrary display parameters such as all can associate with pressure data conversion rate in lamplight brightness, color value, color-ratio, animation or angle, the distribution density of figure, contrast, special efficacy size, and change at every turn be also not limited to change display parameters, such as, contrast and brightness can be changed, by that analogy according to pressure data simultaneously.
In another particular embodiment of the invention, also comprise pressure-responsive setting label in above-mentioned visual effect data set, described pressure-responsive setting label defines the mode of pressure data change described in described visual effect signal response in certain time period and change.
