Accompanying drawing explanation
Fig. 1 is the device schematic diagram of play multimedia archives of the present invention;
Embodiment
Referring to Fig. 1, a kind of device of play multimedia archives, is characterized in that: this device comprises: virtual disk 40, playing module 10, play multimedia archives; Judge module 30, judges whether virtual disk is opened and judge pre-conditioned whether setting; Memory module 50, store files; Labeling module 20, the use state of mark store files.
Said apparatus comprises virtual memory archives economy, the store files that managing virtual disk is stored.
Said apparatus comprises analysis module, analyzes the response message of store files.
Said apparatus comprises removing module, after storing, removes virtual disk.
The invention provides the method for play multimedia archives, the method contains the following step:
1) provide virtual disk;
2) play multimedia archives;
3) judge whether virtual disk is opened;
4) in play multimedia archives process, write store files to virtual disk;
5) the use state of mark store files;
6) judge pre-conditioned whether setting;
7) when pre-conditioned, according to using Determines whether to store store files to entity disk.
Above-mentioned steps 1) after, step 6) comprised: the stored store files of virtual memory archives economy managing virtual disk.
Above-mentioned steps 3) after, step 5) comprised: the response message of analyzing store files.
Above-mentioned steps 5) after, step 6) comprised: after storing, remove virtual disk.
The method of play multimedia archives according to the present invention, provides detailed process step as follows:
Step 101: virtual disk is provided.
After host computer system initialization completes, create a virtual disk, wherein, virtual disk refers to apply for a region in internal memory, then manages by the method for hyperdisk, is equivalent to a virtual entity disk.
After establishment virtual disk completes, can carry out initialization to virtual disk, and be suspended in host computer system virtual disk as disk, just be equivalent to increase in host computer system a pseudo-entity disk, and can carry out unified management to this virtual disk and other entity disk through the job procedure (OS) in host computer system, application programs layer is transparent.The file of application layer reads/stores and waits action and unmodified before identical, does not need to do any variation, and application layer can be accomplished binary compatible completely.At this, the present invention is with the stored store files of virtual memory file system management virtual disk, and wherein, virtual memory files system architecture is on file system layer.
Step 102: play multimedia archives.
In this step, with application program play multimedia archives, and multi-medium file can be music archive or video signal archives.
Step 103: judge whether virtual disk is opened;
Step 104: write store files to virtual disk.
Host computer system, in the middle of the process of broadcasting music, if application program has the action of storage file, first deposits store files in virtual disk in, and the response message of this store files is analyzed, and carries out Classification Management.
Step 105: the use state of mark store files.
In this step, the use state of mark store files, and use state is for changing state or opening, is labeled as and changes state and opening by the mark position in layer store files.
At this, change state is that store files has write new data and has been stored in virtual disk, rather than really writes entity disk; Opening is for store files is just by application program is opened, and all direct entity disks of every store files that is labeled as opening, because application program all may continue to write new data at any time to this store files.When after closing application program store files, stop marking opening, remove the opening of this store files.
Step 106: judge pre-conditioned whether setting;
Step 107: when pre-conditioned, judge whether mark meets default use state.
Switching another multi-medium file etc. as user meets when pre-conditioned, can judge that whether store files is for changing and non-opening, if when store files is still opening, get back to step 104, after closing application program store files, remove the opening of this store files; If store files meets default use state, store files, for changing and non-opening, carry out step 106.
Step 108: store store files to entity disk.
Be labeled as and change and the store files of non-opening meets when pre-conditioned switching another multi-medium file etc., all will write entity disk.In addition, write after entity disk in store files, and relevant information in information and the virtual disk of corresponding this store files of scavenger layer, improve the service efficiency of virtual disk.
Under Root catalogue in virtual disk, there is Test.bin, and the zone bit of store files is for changing and non-opening, be copied to by Test.bin under the Root catalogue of target entity disk, if virtual disk is B disk, target entity disk is C disk, then remove the information of the Test.bin responding in B disk, improve the utilization rate of virtual disk.
Store files is stored to the detailed process of virtual disk, comprises the following step:
Step 1: open store files.
Step 2: judge whether to adopt covering and write.
In this step, cover and write if will adopt, carry out step 5; Cover and write if do not adopt, carry out step 3.
Step 3: check whether entity disk has existed store files.
Be B disk at this virtual disk of giving an example, target entity disk is C disk, and VRFS layer can check under the Root catalogue of C disk whether had Test.bin.
Step 4: copy the response catalogue of store files to virtual disk.
There is Test.bin in the Root catalogue of C disk, Test.bin file copy is arrived under the response catalogue of virtual disk.
Step 5: revise response and store path to virtual disk.
Step 6: store store files to virtual disk.
There is not Test.bin in the Root catalogue of C disk, directly the Test.bin of needs storage is stored to response catalogue.
Application program covers the mode writing and stores store files, even there is store files to exist, destroy this file and write new data, if there is no store files, create new store files and write new data, now need to not search for store files at destination path, only need to revise response and store path to virtual disk.
Step 7: the use state of mark store files.
This step is the step 104 of above stated specification, and the state of change and the opening of mark store files are labeled as and change state and opening by the mark position in layer store files.
The present invention is in music process, first store files is write to virtual disk, and manage with the method for hyperdisk, make it be equivalent to a virtual disk, then switch, suspend broadcasting at multi-medium file, to stop broadcasting, system closedown or the low electricity of system etc. different when pre-conditioned, deposit the store files in virtual disk in entity disk, therefore have the following advantages:
(1) effectively solve music in playing process, because the problem of the audio pause and transition in rhythm or melody that the action of storage file causes reaches and makes the level and smooth smooth object of playing process.
(2) significantly reduce the indegree of writing of entity disk, the serviceable life of effectively improving flash memory.Particularly be applied to the embedded device that need to frequently write, effect is particularly evident.
