Abstract: Disclosed are a method, a system and a terminal apparatus for reproducing content purchased by a user in a plurality of terminals. To this end, a Right Object (RO) is received through an authentication process for content and a service registration process, and is stored in a User Identity Module (UIM). If the UIM is used, a user can use corresponding content in a plurality of terminals through one-time registration. Accordingly, the user having completed the registration can reproduce content in multiple terminals owned by the user based on user identification by means of a license acquired through the registration regardless of a specific terminal, instead of reproducing the content only in a single terminal to which a license has been bound.

Abstract: Provided is a method for delivering all or part of a rights object (RO) of a user associated with the content to other users. The method includes creating a rights object to be transmitted to a second user within a limit of the rights object held by the first user, and forwarding the created rights object to the second user. The method allows each user to share its own RO with other users within the limit of the RO without server authentication.

Abstract: Disclosed is a method of recording and storing a broadcast content received for mobile broadcast services in a transmitting-end level. A broadcast receiving terminal includes a type of the key profile in the header of the recorded file for the particular broadcast content, the CIEK which is used in encrypting the broadcast content and encrypted with the second layer encryption key, and the acquisition information on the second layer encryption key. The acquisition information on the second layer encryption key is included in a corresponding field of the header according to the type of the used profile. As in the SRTP and IPSec, a recorded file format in the transmitting-end level recording is the PDCF. Information associated with the encryption of the encrypted broadcast content is stored in the OMA DRM common header box (ohdr box) of the PDCF recorded file.

Abstract: A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.
