摘要： Current BD specification prescribes that in an ADIP an address is expressed with 21 bits, 19 to indicate the corresponding RUB number, and 2 to be set to 00, 01 and 10 consecutively in the 3 successive ADIP corresponding to one RUB, the smallest addressable portion of data on a disc. From this it derives that at most 32.2 GB of storage space can be addressed. Due to recent developments however, a storage capacity of 35 GB per layer could be achieved. According to the invention, one or more bits are added to the 21 bits currently allocated to express an address. This additional bits however are not stored in the ADIP but left implicit, exempting from a heavy deviation from the current BD encoding rules. The additional bits are reconstructed by an apparatus on the basis of the position on the information carrier where the corresponding RUB is present.

摘要翻译： 当前BD规范规定，在ADIP中，地址用21位表示，19表示相应的RUB号，2表示在对应于一个RUB的3个连续ADIP中连续设置为00,01和10，最小可寻址部分 的光盘上的数据。 从中可以看出，最多可以解决32.2 GB的存储空间。 由于最近的发展，可以实现每层35 GB的存储容量。 根据本发明，一个或多个比特被添加到当前分配用于表示地址的21比特中。 然而，这个附加位不是存储在ADIP中，而是隐含的，可以免除与当前BD编码规则的严重偏离。 基于在存在相应的RUB的信息载体上的位置，装置重构附加位。

摘要： When duplicating the record carrier the angle between the sync words S1 S2 can be preserved at the cost of a change in bit length, or the bit length can be preserved at the expense of changes in the angle between the sync words S1 S2. Consequently a playback device that checks for both changes in the angle between the sync words S1 S2, or between other marks, and for changes in bit length can detect an illegally duplicated record carrier with a high certainty.

摘要翻译： 当复制记录载体时，可以以比特长度改变为代价来保留同步字S1 S2之间的角度，或者可以牺牲同步字S1 S2之间的角度的变化来保持比特长度。 因此，检查同步字S1 S2之间或其他标记之间的角度以及位长度变化中的两个变化的重放装置可以高度确定地检测非法复制的记录载体。

摘要： A drive, a method of operating the drive and a hybrid disc, BD9, comprising the physical layer of a dual layer DVD disc, DVD9, and the application layer of a Blu-ray disc (BD). The disc comprises a reserved area containing a modulation code and a file structure of the application layer and a BD-ROM mark for a copy protection system (CPS) according to the established BD-ROM format. The disc is readable by a conventional DVD drive, but the firmware and specific hardware and software (47,48,49) for detecting the BD-ROM mark is used. In this way, present DVD or BD drives need only firmware upgrades.

摘要： An information carrier for holding user information, the information carrier comprising access information in the form of access information bits for accessing the user information, the access information bits being stored on the information carrier in a variation of a parameter, which variation is detectable by integration detection. The access information bits are scrambled according to a pre-determined scrambling method. By scrambling the access information bits according to a pre-determined scrambling method, detection of the access information is not possible as long as the scrambling method is not known. Using the integration detection technique, the only way to obtain the access information is by knowing how the signal obtained after reading-out the area comprising the access information bits must be processed. In this way illegal retrieval of the user information is further prevented.

摘要： To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.
