Abstract
A method for managing contents of Video On Demand (VOD) services, where a Middle Ware (MW) controls the stored contents on a VOD server according to the VOD service information correlated with a channel is provided. The corresponding device and system are also provided. Therefore, the specific service forms are separated from the stored contents, and the MW controls the contents in a centralized manner according to the service information; the VOD server does not need to store the contents of each service separately, but adds and deletes the stored contents according to the unified control from the MW, thus avoiding repeated storage of the same data for different services.
