Abstract

The present invention discloses a distribution type of audience-choose-broadcasting video system and its data storing and accessing method. Said storing method includes the following steps: dividing a data file into data blocks in a predetermined manner; forming a data checking block for calculating the data blocks having predetermined number; storing the said data blocks and the data checking block into a plurality of predetermined buffer-server in turn in a predetermined manner; and creating corresponding index information for storing data blocks in each said buffer-server. The technical solution of the invention can improve storing efficiency and save a lot of storing space; and increase the safety of data because adopting the distribution type of memory and the data are distributed among a plurality of buffer-server.

Description

technical field

[0001] The invention relates to a distributed video-on-demand system, in particular to data storage and access. Background technique

[0002] Data storage is a key technology involved in video on demand system. In the distributed video-on-demand system, there are very special requirements for data storage. Since the demand for data storage space in the video-on-demand system is very large, how to improve the utilization rate of the storage space in the distributed video-on-demand system becomes a very difficult problem.

[0003] In a conventional distributed video-on-demand system, such as using the method described in US Patent 5649196 (Distributedstorage management system having a cache server and method therefor), the distributed method is based on a geographical division, in order to allow all If all video servers share one or some data streams that need to be buffered, the data must be copied to all buffer servers, which means that there are multiple c...
