摘要:
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.
