System for processing data streams audio / vu00ecdeo (AV)Apparatus for copy control for use in a system for processing data streams audio / vu00ecdeo (AV) that processes a data stream of AV.Method for processing a data stream of AV, method of copying control in the processing of a stream of audio data / vu00ecdeo (AV), and mu00ecdia passu00ecvel reading in the computer.It is a system of processing of data streams AV which includes an input unit of data streams AV that receives a data stream of AV with a field of information.S content of AV including first information for copy control, and a field of content of AV including second control information of the copy.A determination unit which extracts the first and the second control information of the copy of the data stream of AV received and determines whether the first copy control information isAm changed, and a unit for decryption of data stream of AV that processes the data stream of AV received according to predetermined criteria.When the first copy control information has been modified.
