摘要:
An encryptor is provided for encrypting AV data sent from an interface. A controller controls recording of the encrypted AV data by controlling a recorder for recording the encrypted AV data in a magnetic disk. The recorder is controlled by the controller so as to reproduce the data recorded on the disk. A decrypter decrypts the reproduced data that is sent to the interface.

Alternation processes reduce the recording and reproducing speed of a hard disk apparatus.A hard disk apparatus comprising: an HDD 10 for recording AV data onto a hard disk; and stream controlling means 8 which is connected to the HDD 10 and thereby processes the signal of AV data transmitted from an IEEE1394 I/F 7 or the signal of AV data transmitted to the IEEE1394 I/F 7; whereby the hard disk apparatus can record and/or reproduce the AV data, wherein when AV data transfer is not normally completed for a disk access unit which is a minimum continuous unit in the access to the hard disk, an alternation process on a disk access unit basis is carried out so that another disk access unit is used hereafter in place of that disk access unit.

摘要:
Time stamps are attached to packets output from stream data input section by a time stamp-attaching section in a HDD, and the packets are then recorded into a HDD main unit. A stream data-generating section removes the time stamps from the packets subsequent to a predetermined amount of packets last recorded into the HDD main unit and controls the timing of the packets according to the time stamps, and the packets are transferred to an HDD. In the HDD, time stamps start to be generated according to the last predetermined amount of packets, and to the packets transferred thereafter, time stamps are attached in a similar fashion as in the HDD, so that the packets are recorded into the HDD main unit.
