Abstract: A method and apparatus enable high speed transfer of real-time AV data over a bus. When transmitting real-time data of a specific format using isochronous packets, data indicating the transfer rate is added to the isochronous packet. The playback speed can be changed and playback can be stopped while maintaining the transfer rate. High speed data transmission is thus possible.

Abstract: The procedure for acquiring a band is simplified by expressing the propagation delay of a communication medium by using an identifier. After stopping the transmission from a first transmitter (806), a band acquiring means (809) of a second transmitter (814) finds the band which has been used by the first transmitter (806) by using a propagation delay identifier (804) read out from the first transmitter (806) and the maximum transmitted data quantity (805), and starts transmission by using the band. Therefore, the required procedure is simplified, because return and re-acquisition of band are not required at the time of switching the transmitter. In addition, since the propagation delay identifier is used, the band can be utilized effectively.

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

Abstract: A data recording/reproducing device provided with a transmitting/receiving means which transmits/receives data and command signals through a transmission line, a recording/reproducing means which records data received from the transmitting/receiving means on a recording medium at the time of reception and transmits data reproduced from the recording medium to the transmitting/receiving means at the time of transmission, an operating means which generates operation signals for guiding the operation of the recording/reproducing means, a control means which controls the recording/reproducing means in accordance with a command signal or an operating signal, and a switching signal generating means which outputs a switching signal for judging whether the operating signal is effective or ineffective based on the command signal received from the transmitting/receiving means to the control means. When the control means receives an operating means effectuating signal, the control effectuates the operating signal outputted by the operating means. When the control means receives an operating means ineffectuating signal, the control means ineffectuates the operating signal outputted by the operation means.
