Streaming media storage system and storage method

Abstract

The invention relates to a streaming media storage system which comprises a terminal device, a central server, a cache server and at least two storage servers. At least two subsidiary streaming media files formed after segmentation of each streaming media file are respectively stored in the cache server and each storage server. Mapping relations between each streaming media file and storage information of corresponding subsidiary streaming media files are built in the central server. The terminal device sends a streaming media request to the cache server and each storage server according to storage information, acquired from the central server, of corresponding subsidiary streaming media files of a specified streaming media file and obtains feedback from the specified streaming media file. The invention further relates to a storage method based on the streaming media storage system. By means of the streaming media storage system and the storage method, concurrency issues during multi-terminal access are solved, and network access speed of streaming media files can be effectively improved.

Description

technical field [0001] The invention relates to a streaming media storage system and storage method. Background technique [0002] Streaming media refers to the form of transmitting audio, video and multimedia files in the network in a streaming manner; the streaming media file format is a media format that supports streaming transmission and playback. The streaming transmission method is to divide multimedia files such as video and audio into compressed packages through a special compression method, and transmit them continuously and in real time from the server to the user's computer. In a streaming system, users don't have to wait until the entire file is downloaded to see the content as in non-streaming playback, but only need a few seconds or tens of seconds of start-up delay. Use the corresponding player on the user's computer to play the compressed video or audio and other streaming media files, and the remaining parts will continue to be downloaded until the playbac...

Problems solved by technology

[0004] corresponds to the form in which streaming media files are divided into multiple files for storage. In the application of streaming media in the prior art, technicians will separate the multiple files into Stored on multiple servers, this is because a single storage node not only restricts the number of concurrent users, affects the security and reliability of the system, but also is expensive, and has major defects in maintenance and data recovery speed. Therefore, dividing streaming media files into multiple files and storing them on multiple servers can effectively solve the above problems

However, with the wide application of streaming media and the continuous progress of the Internet era, more and more terminal devices are connected to the network. The transmission speed of the network has become an important consideration for people to use the network. The emergence and application of streaming media, It effectively solves the concurrency problem of multi-terminal devices, but for its network transmission, it still depends on the transmission speed of the network where it is located, and there is no effective way to improve it
