摘要: A data transfer method for preventing the malfunction of conventional equipment which does not cope with encipherment at time transmitting enciphered AV information protected by a copyright through an IEEE 1394 bus. In method, cipher identification indicating state real part and are contained in synchronous transferred isochronous communication is effected only on part. According to this transmitter transmits together receiver detects fact that has been from requests send deciphering and, upon receiving response request, deciphers using information.
