Abstract: An optical disc recorder/reproducer, a personal computer, a television receiver, an IRD and so forth are connected mutually via a 1394 serial bus. When data transmitted from the personal computer to the optical disc recorder/reproducer via the 1394 serial bus are to be recorded, an isochronous packet is sent to the recorder/reproducer inclusive of the data to indicate whether the personal computer is a device capable of cognizing copy control information. And depending on whether the source of the transmitted data is a copy control information cognizant device or not, the optical disc recorder/reproducer updates the copy control information with reference to a selected table, and then the updated copy control information is recorded on the optical disc. This system can distinguish between a prerecorded disc and a user-recorded disc, hence achieving exact management of copy control information.
