Problems solved by technology

In the prior art, the traditional file system has great uncertainty in read operations, and multiple read operations at the same time will greatly affect performance; for video servers with multiple channels, commands introduced at any time will affect the output real-time, and even broadcast quality
The traditional file system uses a standard file format and consists of multiple files, which increases the number of hard disk addressing and greatly affects the performance of the storage system; these files often do not support streaming; there are multiple formats of files coexisting and the size is different In extreme cases, this accelerates the generation of hard disk fragments, and also reduces the performance of the storage system a lot, leaving many hidden dangers for stable broadcasting

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0028] A method for establishing a media file system, comprising the following steps:

[0029] (1) First establish the storage method of media files on the disk, that is, divide the disk into areas, including system area, index area and data area, and the basic disk allocation unit is block;

[0030] (2) Then in the media file system on the disk, the media file is saved in units of image groups. The storage unit of the media file is a data block, and each data block saves an image group data, and corresponds to the index item in the disk index area.

[0031] Such as figure 1 As shown, the upper rectangle represents the distribution of the entire disk, from figure 1 It can be seen that the initial disk is the system area 1 and the index area 2, and the other parts are the data area 3. Each data block in the data area 3 contains an image group, whic...

Abstract

This invention relates to a method for building media file system, which belongs to the computer storing technique field of multimedia files. The existing file system can't satisfy the request for real time under the read-write operation, especially under the environment that has multi flows. The property of media file storing system is also affected strongly by using standard file format; such file format sometimes doesn't support the flow transmission, and it produces the hard disk shiver easily. Wherein the media file system which relates to this invention brings forward the picture group as the basic unit of disk read-write through integrating those correlative multi media files information into the media file system, which avoids the limitation in traditional file system.

Description

technical field [0001] The invention belongs to the technical field of computer storage of multimedia files, and in particular relates to a method for establishing a media file system. Background technique [0002] The existing media file system adopts a multi-level index structure. Media file information such as video is stored and transmitted by computer in units of blocks. When accessing media files such as video on information processing equipment such as video servers, it is usually based on logical records. Therefore, whether the length of the physical block on the storage medium matches the length of the logical record directly affects the addressing of the file. Generally can be divided into three situations: [0003] (1) The logical record length is equal to the physical block length; [0004] (2) The logical record length is an integer factor of the physical block length; [0005] (3) The logical record length is not an integer factor of the physical block lengt...
