SYSTEM FOR BROADCASTING IN PERSONAL IP BROADCASTING SYSTEM BY APPLYING PERSONAL DRM AND METHOD USING THE SAME

摘要

A personal DRM(Digital Rights Management)-applied personal multicasting service system and its providing method are provided to allow only an authenticated user to use a service to thus prevent improper contents from being broadcast or an unauthenticated user from illegally using a service. A personal broadcast transmitting unit(130) creates and stores contents, applies a personal DRM code to the created contents, and transmits the same to a personal broadcast receiving unit. The personal broadcast receiving unit(110) receives the transmitted contents, decodes the contents based on corresponding personal DRM certificates, and reproduces the same. After the personal broadcast transmitting unit allocates a channel for transmitting broadcast, a channel management server unit(140) manages the channel, and transmits information of a particular broadcast transmitting unit requested by the personal broadcast receiving unit. An authentication server unit(120) verifies the validity of the personal broadcast transmitting unit and the personal broadcast receiving unit, and issues/manages the personal DRM certificates.
