Abstract: With a reproduction-only disc having a large recording capacity, an interactive function having a higher degree of freedom than the related art can be easily accomplished. A virtual player model corresponding to a function of a player is created and described in Java. BDBasicPlayer 210 detects a user input and the status change of the player and generates an event. An object 211 that implements a listener interface registers an event listener corresponding to an event that the object 211 is caused to receive to BDBasicPlayer 210 before the event takes place. When the event becomes unnecessary, it is unregistered. BDBasicPlayer 210 transmits the event to the object 211 in which the event listener has been registered. The object 211 executes a method corresponding to the received event. The relationships between events and methods can be flexibly set. Thus, a complicated interactive function can be easily accomplished.

Abstract: The more effective is the copy protection provided on a DVD, the greater is the likelihood that the copy protection will adversely interfere with legitimate uses of the disc. In a disc where the content is arranged in physical sectors, it is now proposed to provide subversive regions on the disc having a similar structure to genuine regions. A subversive region and a genuine region will each extend over one or more physical sectors. The subversive region will be provided with physical sector addresses which coincide with addresses of the genuine region. Navigational data will ensure that it is the genuine, rather than the subversive, region which will be accessed during normal play, but the subversive region will effectively hide the genuine region during copying.

Abstract: To copy a copy protected DVD (32), and thereby subvert the copy prot-ection technique, a DVD drive (50) is controlled by a disc copying program (54) to access data at a level other than that at the user data level. For example, if it is the data frame (44) which is read, the DVD drive (50) is controlled to write a data frame (12) to a copy disc (52). During the copying process, the program (54) may be arranged to remove sector IDs and error detection codes from the read data frames (44) and to generate new sector IDs and appropriate ID error detection codes for the data frames (12) to be written to the copy disc (52). This circumvents any copy protection which has been incorporated in the identification data in a data frame of the original disc (52).
