  • Publication number: 20080168155
    Abstract: The present invention relates to a system and method for a web hard disk server to download broadcast contents from a broadcast content providing server and to store a minimum number of broadcast contents in order to avoid redundancy among downloaded broadcast contents. More specifically, among several individual broadcast contents downloaded or to be downloaded to a web hard disk of the web hard disk server, only one instance of identical broadcast contents is physically stored in a shared manner, so that the capacity of the web hard disk can be efficiently used while users perceive that they use the web hard disk individually.
