Deposit the voice data in relief area and be integrated into multimedia file, and in real time the multimedia file of integration is stored in storage inside
Device.
In step S303, the multimedia file in internal storage is write outside storage by central processing unit 103 in real time
Device.
It is the flow chart that the embodiment of the present invention four stores method refering to Fig. 4, Fig. 4.
In step S401, multimedia synthesis module 101 judges whether the view data of video memory buffer reaches
One predetermined threshold value, and judge whether the voice data of audio frequency core buffer reaches the second predetermined threshold value, when view data arrives
When first predetermined threshold value, voice data reach the second predetermined threshold value, view data and voice data are integrated into multimedia literary composition
Part, and multimedia file is stored in internal storage.
In step S401, central processing unit 103 judges not write in internal storage the multimedia literary composition of external memory storage
Whether part reaches the 3rd predetermined threshold value, presets when the multimedia file not writing external memory storage in internal storage reaches the 3rd
During threshold value, the multimedia file not writing external memory storage in internal storage is write external memory storage, by pre-to first
If threshold value, the second predetermined threshold value, the 3rd predetermined threshold value different numerical value is set, can control view data, voice data
Speed in write external memory storage.
Supplementary notes, when, after drive recorder power-off restarting, central processing unit 103 will not write in internal storage
The multimedia file write external memory storage of external memory storage.
Drive recorder and storage method that the present invention provides can be by video memory buffer and audio frequency core buffers
View data and sound Data Integration become multimedia file, and store in internal storage by multimedia file in time, carry
High storage speed, it addition, internal storage is nonvolatile memory, even if when unexpected power-off, remains to preserve camera data,
Guarantee the integrity of data, it is ensured that view data, voice data are carried out full storage, by multimedia file from internal storage
A large amount of multimedia files can be dumped in the storage device that SD card, TF card etc. are convenient for carrying by write external memory storage, it is possible to
To dump in cloud storage equipment by multimedia files a large amount of in internal storage, can ensure that the storage of enough memory spaces is all
Multimedia file, and facilitate user that multi-medium data is copied.
Above example is merely to illustrate the present invention, rather than limitation of the present invention, relevant technical staff, without departing from invention
In the case of spirit and scope, it is also possible to make a variety of changes and deform, the technical scheme of the most all equivalents falls within this
Bright protection category.
