    摘要: A method of packaging broadcast contents are provided. The method includes: extracting a copy control bit from input broadcast contents and determining whether the broadcast contents will be stored after being encrypted based on the extracted copy control bit; creating usage rule information which includes an encryption method of the broadcast contents if it is determined that the broadcast contents will be stored after being encrypted; extracting the copy control bit from each new broadcast content sequentially input and detecting broadcast contents which include copy control bits indicating that the broadcast contents will be stored without being encrypted; and encrypting the input broadcast contents through the broadcast contents before the detected broadcast contents using the encryption method and packaging and storing the encrypted broadcast contents and the usage rule information. Therefore, the unauthorized copying of broadcast contents transmitted through a digital broadcast receiver can be prevented.

    摘要: A method and apparatus for providing digital rights management (DRM) content and a license, and a method and apparatus for using DRM content are provided. The method of providing DRM content and a license includes selecting usage conditions for content; transforming the usage conditions into a secure database (DB); and adding the secure DB to a license. The method of using DRM content generated by applying DRM includes searching for a license corresponding to the DRM content; authenticating a user who wants to use the DRM content; extracting usage conditions included in the license by using a secure DB agent, and confirming whether or not an action desired to be performed by the user satisfies the usage conditions; and if the action desired to be performed by the user satisfies the usage conditions, using the DRM content according to the action.
