Multimedia file storing and applying method, related device and system

Abstract

The embodiment of the invention discloses a multimedia file storing and playing method as well as a related device and a system. The multimedia file storing method comprises the following steps: dividing a first hard disk group and a second hard disk group; cutting a multimedia file to be stored into multiple segment files with equal size according to the size of a pre-set segment file; uniformlystoring the segment files in the hard disks of the second hard disk group; establishing an index file and storing the index file in the first hard disk group; and establishing a segment record file and storing the segment record file in the first hard disk group so that a multimedia server acquires the content of a corresponding segment file according to the index file and the segment record filewhen a play request of a multimedia client is received. Through the scheme of the invention, the response speed of the multimedia server to a multimedia broadcasting client is effectively improved, load balance of each hard disk in single multimedia server is realized, and the network bandwidth is saved at the same time.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method for storing and playing multimedia files, a related device and a system. Background technique [0002] With the development of network technology, computer technology and multimedia technology, the application of multimedia on-demand technology is becoming more and more extensive. The user can perform multimedia on-demand through the multimedia on-demand client, and the multimedia server reads the data (such as video, audio, etc.) contained in the corresponding multimedia file after receiving the playback request from the user, and transmits it to the multimedia on-demand client through the network end. In the application of multimedia on demand, the storage method of multimedia files is one of the key technologies involved in the multimedia on demand system. [0003] A method for storing multimedia files is to divide the multimedia files into data blocks according...

Problems solved by technology

[0004] Although the above method can save the storage space of the multimedia server, because the multimedia files are stored on different buffer servers in the form of data blocks, when the multimedia server receives the request for accessing the multimedia files from the multimedia on-demand client, it must first pass The network obtains the data block corresponding to the multimedia file from multiple buffer servers, which inevitably affects the reading speed of the multimedia server to the multimedia file, thereby affecting the response speed of the multimedia server to the multimedia on-demand client

On the other hand, there are usually multiple hard disks in a single cache server. The above method only stores data blocks in different cache servers, without considering the load balancing problem of multiple hard disks in a single cache server, which may lead to a single cache server One of the hard drives in the
