Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not entire infrastructure.
Embodiment one
Fig. 1 is the process flow diagram of the striding equipment synchronous method of a kind of shuffle playlist in the embodiment of the present invention one, the present embodiment is applicable to needs opertaing device to coordinate shuffle multimedia file situation with playback equipment, the method can be performed by the striding equipment synchronous device of shuffle playlist, this device realizes by the mode of hardware and/or software, this device is configured in the opertaing device that user uses usually, and opertaing device can be the mobile terminal of such as mobile phone, panel computer.
As shown in Figure 1, described method specifically comprises the steps:
The multimedia file quantity comprised in the non-playlist of step 110, acquisition opertaing device.
Wherein, the multimedia file list after described non-playlist and the current multimedia file play.Described multimedia file can be video, audio frequency etc.
Step 120, generate one group of unduplicated random number according to described multimedia file quantity.
Wherein, the quantity of described random number can be equal with described multimedia file quantity, and described random number and described multimedia file one_to_one corresponding, can play mark action.Exemplary, described random number can be chosen one group and be more than or equal to zero and the one group of integer being less than described multimedia file quantity, described random number can according to multimedia file one_to_one corresponding from front to back in ascending order and non-playlist, also can according to multimedia file one_to_one corresponding from front to back in descending order and non-playlist, also can certain rule preset corresponding, be not specifically limited.
Step 130, the random number according to generating, described non-playlist and default random list create-rule form new non-playlist.
Wherein, random list create-rule, namely according to the generation order of described random number, the arrangement rearranged the multimedia file in described non-playlist is to form the rule of new non-playlist.Concrete, can select the multimedia file in return file of a certain fixed position, according to the generation order of random number, multimedia corresponding for random number is taken out by order, and exchanges with described swap file; Can according to the generation order of random number, by the arrangement of the multimedia file of correspondence order, also can arrange random number according to a certain fixing rule, multimedia file corresponding to described random number, according to identical regularly arranged, is not specifically limited.
Preferably, after forming new non-playlist according to the random number generated, described non-playlist and default random list create-rule, also comprise: in described current play list, adopt non-playlist described in new non-playlist replacement to form new playlist.
Wherein, described current play list is the playlist of current all multimedia files, namely comprises the playlist of play multimedia file, the multimedia file play and non-play multimedia file.
Step 140, playback equipment is sent to make described playback equipment form new non-playlist according to described random list create-rule the random number of generation.
Wherein, the random number of generation is sent to playback equipment, make described playback equipment according to the new non-playlist of identical the form of the rules, to ensure that playback equipment is identical with the playlist of opertaing device, namely realize the synchronous of shuffle playlist.This case opertaing device only need send to playback equipment can realize the synchronous of shuffle playlist one group of random number that opertaing device generates, compared in existing shuffle playlist synchronous method, opertaing device need the new broadcasting queue synchronization generated to playback equipment, this case reduces data processing amount between opertaing device and playback equipment and transmission volume, improves the synchronous efficiency of shuffle playlist between opertaing device and playback equipment.
The technical scheme of the present embodiment, the multimedia file quantity comprised in self non-playlist is obtained by opertaing device, one group of unduplicated random number is generated according to described multimedia file quantity, and according to the random number generated, described non-playlist and default random list create-rule form new non-playlist, playback equipment the random number of generation is sent to make described playback equipment form new non-playlist according to the random list create-rule identical with opertaing device again, improve the synchronous efficiency of shuffle playlist between opertaing device and playback equipment, optimize result of broadcast.
