摘要： A recording and reproducing apparatus is characterized in that said apparatus has: inputting means for receiving a packet data which is based on IEEE 1394, and in which signal information for indicating copy right information of an AV data (hereinafter, referred to as EMI) is provided in a header of a packet according to IEEE 1394; and recording and reproducing means for recording and reproducing an AV data and the EMI which are held in the packet data received by said inputting means. Four kinds of EMI are used, and, when an AV data indicating allowance “copy one generation” among them is to be recorded, said recording and reproducing means performs recording while rewriting the EMI to EMI indicating “no more copy.”

摘要： The problem to be solved is that once copyright claimed AV data is passed to application software, the application software can freely process the AV data for recording, etc., defeating the purpose of copyright protection. The invention provides a computer which comprises a system section 12 and an application software section 13, and which takes in copyright claimed, encrypted data via a digital interface 1 for processing therein, wherein the system section 12 judges that the application software section 13 is legitimate application software for the protection of copyright, and if the application software is a legitimate one, the system section 12 passes a key for the encrypted data to the application software section 13.

摘要： A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STB 1 transmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR device 2 decrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB 1, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.

摘要： It is objected to simplify a procedure concerning bandwidth acquisition. Bandwidth acquiring means 809 of a second transmitting apparatus 814 acquires a bandwidth which was used by a first transmitting apparatus 806 by using a propagation delay identifier 804 read from first transmitting apparatus 806 and a maximum transmission data size 805 after stopping transmission of first transmitting apparatus 806. Each apparatus is composed so that transmission is started using this bandwidth and because returning and re-acquisition are not accompanied when the transmission is switched, necessary procedure can be simplified. Further, it is possible to effectively use the bandwidth by using a propagation delay identifier.

摘要： A data transfer method which eliminates erroneous operation of conventional devices not supporting encryption when copy-protected AV information is encrypted and sent on an IEEE 1394 bus. Synchronous data transferred through isochronous communication contains i) encryption identification information for indicating encryption of actual data and ii) actual data. Only the actual data is encrypted. Encryption identification information indicating encryption of actual data in synchronous data is sent together with actual data from the sending device. A receiving device detecting encryption of actual data from this encryption identification information requests decrypting information from the sending device. The receiving device decrypts the actual data using decrypting information received from the sending device according to this request.
