Description
Technical field
The utility model relates to a kind of media player, especially relates to a kind of USB media player based on the Android platform.
Background technology
Along with the in-depth of intelligent movable, more and more higher for the requirement of cell phone entertainment function, particularly for management and the broadcast of multimedia file, user's requirement also improves thereupon.At present the intelligent movable mobile phone is a lot of for the technology of the multimedia administration of SD card and the network storage and broadcast, and the technology comparative maturity.Having ready conditions also is necessary to expand to the compatible of more memory device and manages, and realizes unified interface, to adapt to the experience of user's requirements at the higher level.
But can't manage for the multimedia file in the USB storage and play with regard to the Android platform at present, just can accomplish simple synchronously, can not satisfy the user and plug USB and just can work as the such experience requirements of music walkman, video player and picture browsing (gallery function).
The utility model content
For solving the deficiencies in the prior art, the utility model proposes a kind of USB media player based on the Android platform, the Android platform can be managed the multimedia file in the USB storage and play.
The utility model adopts following technical scheme to realize: a kind of USB media player based on the Android platform, connect USB storage by USB interface, and described USB media player comprises:
Video player;
Audio player;
Be used for monitoring the USB device monitoring module whether described USB interface connects described USB storage, it connects USB interface;
Be used for carrying out when described USB interface connects described USB storage the drive load communication module of USB device drive load communication, it connects described USB device monitoring module;
Be used for carrying out usb file that data docks processing to connection module with described USB storage, it connects described USB interface;
Being used for carrying out the USB device drive load with described drive load communication module communicates by letter, and control described usb file connection module is obtained multimedia file from described USB storage, resolve and be sent to the Android kernel module that playback process is carried out in described video player or the control of described audio player behind the described multimedia file, described Android kernel module connects respectively described drive load communication module, described usb file to connection module, described video player and described audio player.
Compared with prior art, the utlity model has following beneficial effect:
The utility model proposes the USB media player that adopts the Android platform, can carry out on the synchronous basis of data at existing Android platform and USB storage, realized play-overing multimedia (such as music, video) in the USB storage by the Android platform, have simple in structure, realize being easy to advantage.
Description of drawings
Fig. 1 adopts the USB media player of Android platform and the connection diagram of USB storage;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the USB media player 1 that adopts the Android platform and USB storage 2 are connected by USB interface, are monitored and are managed by 1 pair of USB storage 2 of USB media player, and then USB storage 2 interior multimedia files are managed and play.
In conjunction with shown in Figure 2, adopt the USB media player 1 of Android platform specifically to comprise: the Android kernel module 11 of realizing Android operating system; The usb 12 that is connected with USB storage 2; Be serially connected in USB device monitoring module 13 and drive load communication module 14 between Android kernel module 11 and the usb 12, whether connecting outside USB device driving by 13 pairs of USB interface of USB device monitoring module monitors, when finding outside USB device drive load is arranged, can send event message to Android kernel module 11 by drive load communication module 14 communicates, a Volume Daemon(Vold is arranged in the middle of the Android kernel module 11), utilize Vold that the event message of passing through of sending out on the drive load communication module 14 is processed; Be connected to usb file between Android kernel module 11 and the usb 12 to connection module 15, when the driving arrangement that monitors current loading when Android kernel module 11 is USB device, Android kernel module 11 notice usb files hang over USB storage 2 under the file directory of Android kernel module 11 appointments to connection module 15, make USB storage 2 as a mount point in the Android operating system, finish Android kernel module 11 and dock with the data of USB storage 2; The video player 16 and the audio player 17 that connect Android kernel module 11 and processed by 11 controls of Android kernel module.
After finishing Android kernel module 11 and the data of USB storage 2 docked, Android kernel module 11 obtains the information of the multimedia file in the USB storage 2, and it is resolved, and finally the data that are resolved to are stored in the data pool of Android kernel module 11.
The USB media player 1 that the utility model proposes carries out interface display and the playing function that offers user interactions by the multimedia file that obtains in the USB storage 2.Wherein, Android kernel module 11 control video players 16 or/and audio player 17 carries out video playback audio frequency play and have two kinds and inspire opportunity, a kind of is user's active request, another kind is when having detected USB drive load and carry and finishing, and is inspired by Android kernel module 11 and finishes.
Open video player 16 or/and audio player 17 also can be opened video player 16 or/and audio player 17 by user selection by 11 controls of Android kernel module.Android kernel module 11 obtains multimedia file to connection module 15 by usb file first and resolves from USB storage 2, and finally the data that are resolved to are stored in the data pool of Android kernel module 11, from data pool, obtain again the information of multimedia file and directly pass to video player 16 or/and audio player 17 carries out playback process.
To sum up, the utility model proposes the USB media player that adopts the Android platform, can carry out on the synchronous basis of data at existing Android platform and USB storage, realized play-overing multimedia (such as music, video) in the USB storage by the Android platform, have simple in structure, realize being easy to advantage.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
