INFORMATION RECORDING APPARATUS AND METHOD, AND INFORMATION REPRODUCTION APPARATUS AND METHOD

摘要

An information recording apparatus and method and an information reproduction apparatus and method capable of appropriately managing AV data security information. A copy limit information detection unit (15) acquires copy limit information (CCI_i) of a video signal supplied from a terminal (11) and outputs it to a controller (19). According to the CCI_i supplied from the copy limit information detection unit (15), the controller (19) determines the values of is_not_free and is_encrypted and outputs them to a source packetization unit (18). A source packet generated by the source packetization unit (18) is encrypted according to the setting of is_encrypted by an encryption unit (20) and recorded in a recording medium (24). The present invention can be applied to an information processing apparatus for processing AV data.
