Problems solved by technology

[0007] These methods have the following disadvantages: First, the retrieval speed is slow
Second, the complexity of business logic is high
Either increase the index file maintenance module, or use the database system, in short, increase the complexity of business logic

Embodiment Construction

[0024] Specific embodiments of the present invention are as follows (as figure 1 shown):

[0025] Step 1: Get initial configuration. Determine the total available hard disk capacity of the system a, the size of each video file b and the number of video sources c.

[0026] Step 2: Count the number of directories and files. Calculate the number of subdirectories of each video source and the number of files in each directory according to the total capacity of the hard disk available in the system a, the size of each video file b, and the number of video sources c (rounded down).

[0027] Step 3: Create a video source directory. Create c video source directories, named S(1), S(2), S(3), ..., S(c) in turn, and then create d subdirectories in each video source directory, named D in turn (1), D(2), D(3), ..., D(d) (such as figure 2 shown).

[0028] Among them, S(i) represents the name of the video source directory whose serial number is i, and the format is a fixed width r...

Abstract

A storage organization of digital video videotaping files is structurally characterized in that one video source directory is respectively built for each way of video source on a hard disc, a plurality of subdirectories are built below each video source directory, and videotaping files with the same quantity as the subdirectories are stored below each subdirectory. A naming method of the search method of the digital video videotaping files is naming for the directory and files of the digital video videotaping file storage organization, namely the directory is named according to the number order, the files are named in an order of number order + connector + time of starting videotaping + connector + videotaping duration, the number order format in file names is with right-alignment fixed width, and 0 is supplemented on the left side not wide enough. The storage organization and the search method of digital video videotaping files have the advantages that: 1 directory structural characteristics of a file system are given full play to and search is fast; 2 index files are not needed to be maintained and a database system is not needed, so that the business logic is simple; and 3 file names are short and accordingly can be displayed on limited graphical interfaces conveniently.

Description

technical field [0001] The invention relates to a file storage method of a digital video recording system, in particular to a storage directory structure, file naming and file retrieval method of a digital video recording file. Background technique [0002] Digital Video Recorder (DVR, Digital Video Recorder) is the core equipment of the video surveillance system. Its main function is to sample, encode and compress multiple video signals, store the compressed digital video information on the hard disk, and provide Video playback function for subsequent inquiries. The digital video recording system with network function also supports the use of client software to receive and play real-time digital video on the computer, as well as query and playback video files and other functions. The digital video recording system adopts the method of cyclic coverage for recording, that is, when the hard disk space is used up, the earliest recording files are always overwritten to store ne...
