In order to preferably describe the embodiment of the present invention, with reference to Fig. 5, comprising:

Process one: start (system TV receives the order that switches between two media music applications, such as: QQ music and cruel Switch between dog music, system, which issues, interrupts character Command, and 0x100 represents order switching.)

Two: TV system of process starts media application name module, and system tables look-up to obtain media application by root mesh packet name Title, TV system read packet name and media name one differentiate and (judge whether each application is media application) two apply whether be The relevant application of media? such as: table packet name of media application name module in is corresponding with the title of media application, Media_ Name (x1)=com.ttl.qqmusic (QQ music);

Media_Name (x2)=com.kugo.music (KuGoo music)

Media_Name (x2)=com.iqyi.music (unusual music)

Does is three: TV system discovery of process two music application? such as: QQ music, KuGoo music application, two kinds of situations: A kind of situation, TV system discovery are currently at the application that front and back is two media, such as: Media_Name (x1)= Com.ttl.qqmusic (QQ music)

Media_Name (x2)=com.kugo.music (KuGoo music)

It is the application of two media that seven: TV system discovery of process, which is currently at front and back not, before system closes media application Backstage identity module.Such as: Media_Name (x1)=com.ttl.qqmusic (QQ music)

Media_Name (x2)=com.kugo.TT (KuGoo magazine);

Process four: a kind of situation, TV system discovery are currently at the application that front and back is two media,

System starts media application front and back identity module, and system should receive key-press event mode by media and differentiate currently Using in foreground or backstage, the application for receiving key-press event is foreground application, other are background application, 1, before mark Platform, 0, identify backstage such as: KuGoo music: Media_Identity_Mode (x2)=0;

Does is five: TV system discovery foreground application of process music application? such as: QQ music: Media_Identity_Mode (x1)=1, two kinds of situations: a kind of situation: TV system discovery foreground application is music application, such as: QQ music: Media_ Identity_Mode (x1)=1, another situation: TV system discovery foreground application is not music application, such as: Media_ Name (x2)=com.kugo.TT (KuGoo magazine), Media_Identity_Mode (x2)=0;

Process six: a kind of situation: TV system discovery foreground application is music application, abutment body before TV system discovery media application The packet name (QQ music) of part module is foreground application, and system, which is opened, applies dynamic memory detecting module, and system reads each application The maximum value of memory carries out being averaged for memory according to multiple applications with the entire region of memory of TV system, such as: input 2 is answered With being QQ music respectively, KuGoo music, TV system is interior in total to save as 512MB, obtains the averagely interior of foreground application and saves as 256MB;

The application number of input: Input_num_ap (x1)=2

The memory sum of TV system: TV_RAM (x1)=256M

It is total using average memory:

TV_AVE_RAM=TV_RAM (x1)/Input_num_ap (x1)=256/2=256M.

It is specific:

1, system, which obtains, applies memory headroom size itself,

Such as: QQ music memory maximum demand 50MB,

KuGoo music memory maximum demand 1000MB, if it is greater than the size that application needs, overabsorption is to QQ, KuGoo application It causes to waste.

2, system obtains the space size in total of physical memory, is dynamically averaging according to Video Applications number, and system obtains The memory size of the application of mean allocation, such as: multiple QQ music applications amount to 10,

TV_AVE_RAM=TV_RAM (x1)/Input_num_ap (x1)=512/10=51MB.

3, system compares the value of the memory applications of physical allocation with using memory size itself, and physical application space is big In application memory space, default application maximum memory size.Such as: QQ music memory maximum demand 50MB is distributed in time 51MB finally sets QQ music physical memory 50MB.

Process eight: another situation: TV system discovery foreground application is not music application, TV system discovery music (KuGoo Music) application is background application, system starting memory moves router-module, and system is read using dynamic memory detecting module Value is with after the half of background application downloading data, and the data transmission that backstage is downloaded is into router memory block 33, system Periodically 5 minutes, router memory space can only save the maximum memory for saving data of rear end time longest.Such as: routing is deposited Control 512MB is stored up, 5 minutes arrive, and router saves 3 songs of KuGoo music application, likes you 10,000 years, and ice rain, the heart only has you, MP3 music data at this time keeps in router, and router finds TV system background there are also other media applications, and router is sent The internal storage data order for stopping receiving application, does not receive the data of other application, and router also sends the finger for stopping other application It enables to TV.

Nine: TV system of process opens routing and closes background application module, and route system is automatically big by the running background time Application in 5 minutes is closed, and the data that TV is deposited at end empty, other background applications are out of service, and it is slow that TV system releases backstage The data deposited, such as: TV system receives the order of routing, out of service 1,000 applications harked, the sounds such as MP3 to empty the cache Happy data.

Ten: TV system of process, which is opened, reminds backstage media display module, and TV system is aobvious according to the background application title of closing Show that display is from the background in the title of the application of operation in the upper right corner, display caching to the big of router in the upper left corner of foreground application It is small.Such as: display closes 1,000 and harks that music, display KuGoo music are cached to 3 song of router, like you 10,000 years, ice rain, The heart only has you.

The executing subject of the storage controlling method of the application cache data of above-mentioned each embodiment all can be terminal.More into One step, the storage controlling method of the clarifier application cache data can be by installing client application caching number at the terminal According to storage control program realize, wherein the terminal includes but is not limited to smart television, mobile phone, pad, laptop etc., excellent It is selected as smart television.
