发明名称 Information recording apparatus and method, information reproduction apparatus and method, information recording medium, program storage medium and program
摘要 An information recording apparatus and method and an information reproduction apparatus and method enable security information of AV data to be managed appropriately. A copy control information detection section acquires copy control information (CCI_i) of a video signal supplied from a terminal and outputs it to a controller. The controller determines the values of is_not_free and is_encrypted based on the copy control information supplied from the copy control information detection section and outputs the values to a source packetization section. Is_not_free and is_encrypted represent a limitation to copying and an encryption mode of data recorded on a recording medium, respectively, and are described in the header of a source packet produced by a source packetization section. The source packet produced by the source packetization section is encrypted in accordance with the value of is_encrypted, undergoes a predetermined process by an encryption section, and is then recorded onto the recording medium.
