A method for recording and storing broadcast content in a mobile broadcast receiving terminal, comprising: generating a first encryption key; encrypting a broadcast content received from a mobile broadcast system using the first encryption key; generating a recorded file including the encrypted broadcast content; and storing, in a header of the recorded file, a field value indicating a OMA-BCAST DRM profile or a smartcard profile; wherein, when the first encryption key is encrypted once, the first encryption key is encrypted with a second encryption key, the encrypted first encryption key is stored in the header of the recorded file, and acquisition information on the second encryption key is stored in the header of the recorded file, wherein, when the first encryption key is encrypted twice, the first encryption key is encrypted with a third encryption key, the encrypted first encryption key is encrypted with the second encryption key, the twice encrypted first encryption key is stored in the header of the recorded file, and the acquisition information on the second encryption key and acquisition information on the third encryption key is stored in the header of the recorded file; wherein the acquisition information on the second encryption key includes identification information for identifying the second encryption key and address information of a server providing the second encryption key, and the acquisition information on the third encryption key includes identification information for identifying the third encryption key and address information of a server providing the third encryption key; wherein the first encryption key is a Content Item Encryption Key, CIEK, the second encryption key is a second layer encryption key, and the third encryption key is a Traffic Binding Key, TBK; wherein the acquisition information on the TBK is stored in an OMA BCAST TBK information box of an extended headers box; wherein when the field value corresponds to the smartcard profile, an OMA-BCAST profile information box having the field value is included in an OMA DRM common header box. generating a first encryption key; encrypting a broadcast content received from a mobile broadcast system using the first encryption key; generating a recorded file including the encrypted broadcast content; and storing, in a header of the recorded file, a field value indicating a OMA-BCAST DRM profile or a smartcard profile; wherein, when the first encryption key is encrypted once, the first encryption key is encrypted with a second encryption key, the encrypted first encryption key is stored in the header of the recorded file, and acquisition information on the second encryption key is stored in the header of the recorded file, wherein, when the first encryption key is encrypted twice, the first encryption key is encrypted with a third encryption key, the encrypted first encryption key is encrypted with the second encryption key, the twice encrypted first encryption key is stored in the header of the recorded file, and the acquisition information on the second encryption key and acquisition information on the third encryption key is stored in the header of the recorded file; wherein the acquisition information on the second encryption key includes identification information for identifying the second encryption key and address information of a server providing the second encryption key, and the acquisition information on the third encryption key includes identification information for identifying the third encryption key and address information of a server providing the third encryption key; wherein the first encryption key is a Content Item Encryption Key, CIEK, the second encryption key is a second layer encryption key, and the third encryption key is a Traffic Binding Key, TBK; wherein the acquisition information on the TBK is stored in an OMA BCAST TBK information box of an extended headers box; wherein when the field value corresponds to the smartcard profile, an OMA-BCAST profile information box having the field value is included in an OMA DRM common header box.
