Method and system realizing content dynamically publishing based on hotness of user's demand

Abstract

The invention discloses a method and a system for realizing dynamic publication of content according to VOD (Video-On-Demand) heat degree of users, wherein the method comprises the following steps that: a plurality of nodes of a content distribution network respectively record and store programs in a specified time period according to preset strategy, and display the recorded programs to all users; when a program ordered by some user is not at the present node, the node where the program is stored actually is acquired through inquiry, and VOD is carried out through the node actually storing the program. The system comprises a plurality of nodes of the content distribution network and a media control center. Through the method and the system of the invention, identical content does not need to be recorded at all content distribution nodes; a download command is initiated only if the number of access users exceeds a threshold value. On the one hand, the storage space of the system is greatly saved, and on the other hand, the load of the system is balanced without affecting the access time delay of users and the processing efficiency of the system.

Description

technical field [0001] The invention relates to the field of storage and distribution of multimedia content, in particular to a method and system for realizing dynamic release of content according to user demand popularity. Background technique [0002] At present, in a distributed CDN (Content Distribution Network) system, all media content needs to be stored or recorded on all CDN nodes, which will cause a large amount of unnecessary waste of storage space in the entire system; however, if not on each node All media content is stored, and it may cause a large number of tandem requests when a large number of users order the same file, thus posing a threat to the system processing efficiency. Contents of the invention [0003] In view of the above analysis, the purpose of the present invention is to provide a method and system for dynamically publishing content according to the user's order popularity, so as to solve the problem that all media content in the prior art need...
