Abstract:
1. A method of packaging broadcast contents in a computer device comprising a processor having computer device-executable instructions, the method comprising: (a) extracting, using the processor, a copy control bit from first broadcast contents which are input and determining whether the first broadcast contents are to be encrypted before being stored based on the extracted copy control bit; (b) in response to determining in operation (a) that the first broadcast contents are to be encrypted before being stored, creating first usage rule information which comprises an encryption method, extracting the copy control bit from each of second broadcast contents which are sequentially input after the first broadcast contents, and determining whether each of the second broadcast contents is not to be encrypted before being stored based on the extracted copy control bit; and (c) in response to determining in operation (b) that one of the second broadcast contents is not to be encrypted before being stored, encrypting the first broadcast contents which are determined in operation (a) to be encrypted before being stored and the remaining second broadcast contents, excluding the one of the second broadcast contents that is not to be encrypted before being stored, which are determined in operation (b) to be encrypted before being stored, using the encryption method, and packaging and storing the encrypted first and second broadcast contents and the first usage rule information without generating other usage rule information for the encrypted second broadcast contents.
