Embodiment Construction

[0043] When the data of the existing multi-video channels is stored, the stored data of each channel is scattered. When the subsequent operation of deleting the data of a certain channel is performed, fragments will be generated in the storage area. After the video system has been running for a long time, the number of fragments generated will also continue to increase. Once the storage space in the storage area is full, and the fragments need to be used to store the data packets generated by each video channel, the storage stability and storage efficiency of the data will be seriously affected.

[0044] Therefore, the embodiment of the present invention provides a solution, the basic idea of ​​which is: divide a storage area for different video channels, and each video channel performs data cyclic storage in the corresponding storage area.

[0045] After the disk is formatted, a corresponding storage area is established for each video channel, and a storage area can be a disk...

Abstract

The invention discloses a data storage method and device. The method comprises the following steps: receiving a data pack which is needed to be stored and transmitted from a data channel, judging whether enough residual space for storing the data pack to be stored is in a storage area corresponding to the data channel; if so, determining the storage information of the data pack, storing the data pack in the storage place of the storage area according to the indication of the storage information; if not, determining the number of data packs needed to deleted according to preset conditions, deleting the same number of data packs with earliest storage time in the storage area, and then executing the judgment operation. The data storage method and device can not generate fragment during the data storage process and increase the stability and efficiency of the data storage.

Description

technical field [0001] The present invention relates to the field of data processing, and more specifically, to a data storage method and device. Background technique [0002] When the existing video recording system stores data, multiple video channels share the same storage area. The storage area is realized by a physical disk or a disk array, and sequentially stores the received data packets. When storing the data packets corresponding to each recording channel, the data packets of multiple recording channels are sequentially stored in the storage area according to the time when each recording channel requests to store the data packets. [0003] Since the data corresponding to each recording channel is in a discontinuous position in the storage area, when data of a certain recording channel is deleted, fragments will be generated in the storage area. In particular, there are multiple video channels, and after multiple data deletions, the number of fragments formed in th...
