Abstract
The invention provides a method for storing video/audio data. Formatting is carried out on a storage card, the storage card is evenly partitioned into multiple storage blocks according to fixed size, each storage block is divided into an index part and a data part, the index parts store block index information generated by videos, and the data parts store the video/audio data. The invention further provides a device for storing the video/audio data. According to the method and device for storing the video/audio data, the index information is scattered to all the positions of the storage card, erasing times are evenly distributed, and the service life of the storage card can be prolonged.
Description
Technical field
The present invention relates to security protection video monitoring product technical field, relate in particular to a kind of storage means and memory storage of video/audio.
Background technology
At present a lot of IP Camera products are all with storage card, if SD card, TF card etc. are as the storage medium of video/audio.But this class storage card has the restriction of erasable number of times, in the time that erasable number of times reaches stipulated number, they will damage.Most security product can produce an index file for storing index information in the video/audio of storage video recording, and index information has comprised start time, length data and some other additional information of each video file.The object of index file is to want the video/audio of video recording for user can be navigated to fast.The shortcoming that produces separately an index file is, index file will be synchronizeed and upgrade with the video/audio of video recording, upgrades frequently, causes the storage area at index file place erasable frequent, thereby cause storage card regional area easily to damage, storage medium more easily damages like this.
Summary of the invention
One of the technical problem to be solved in the present invention, is to provide a kind of storage means of video/audio, reduces the erasable number of times of storage card, extends the storage card life-span.
One of problem of the present invention is achieved in that a kind of storage means of video/audio,
Storage card is formatd, make storage card average mark be slit into multiple storage blocks;
Each storage block comprises piece description and blocks of data two parts, describes the piece index information of partly storing this piece, described blocks of data part storage video/audio for described.
Further, the format of storage card is specially: the piece index information of the piece of each storage block being described to part carries out initialization, and is labeled as unused state.
Further, when storage video/audio, in internal memory, synchronously piece index information is upgraded, in the time that current storage block is write full or video recording end, this piece index information is write in current storage block.
Further, storage video/audio, the concrete steps that the piece index information of generation is stored in each storage block comprise,
After step 10, device power, the piece index information of all storage blocks in storage card is read in the internal memory of system, and form an internal memory chained list;
Step 20, start video recording or video process storage block switch time, from internal memory chained list, find out one and be labeled as untapped index information, upgrade this piece index information flag state for using;
Step 30, in blocks of data part corresponding to current storage block, write video/audio, and data length and the storage synchronously upgraded in piece index information corresponding with this piece in internal memory chained list finish temporal information;
Step 40, in the time that current storage block is write full or video recording and is finished, piece index information corresponding to this storage block in the internal memory chained list after upgrading write to piece corresponding to this storage block and describes part;
Step 50, in next storage block, repeating step 20 is to the operation of step 40, until video recording finishes.
Further, after described step 50, further comprise:
Step 60, when all storage blocks are all labeled as while having used state, adopt sequential loop coverage mode video/audio to be covered to the storage block using the earliest, thereby guarantee to be uniform to the number of operations of each storage block.
Further, the storage space of described each storage block is 4～16Mbyte.
Further, described index information comprises: resolution, audio coding form and the audio sample rate of the frame per second of the coded format of the video data of end time of initial video time, storage, data length, storage, the video data of storage, the video data of storage.
Two of the technical problem to be solved in the present invention, is to provide a kind of memory storage of video/audio, reduces the erasable number of times of storage card, extends the storage card life-span.
Two of problem of the present invention is achieved in that a kind of memory storage of video/audio, comprises formatting module and memory module;
Described formatting module: for storage card is formatd, make storage card average mark be slit into multiple storage blocks;
Described memory module: for storing video/audio, and the piece index information of generation is stored in the storage block of this video/audio of storage.
