摘要： A reproducing apparatus (1) reproduces content stored in encrypted form on a record carrier (2). The record carrier (2) further stores a carrier region code (RCC) indicating in which region content shall be allowed to be reproduced and an encrypted region key (RK) for decrypting content, in order to make it more difficult to hack a reproducing apparatus (1) for it to play record carriers having a wrong region code. The reproducing apparatus (1) has a region code storage (10) for storing a device region code (RCD), and a device key storage (11) for storing a device key (DK), which device key (DK) is different for all regions. The reproducing apparatus (1) reads a carrier region code (RCC) from the record carrier (2), checks if the carrier region code (RCC) matches the device region code (RCD), reads the encrypted region key (RK) from the record carrier (2), decrypts the encrypted region key (RK) using said device key (DK) in case the carrier region code (RCC) matches the device region code (RCD), reads the encrypted content from the record carrier (2), decrypts the encrypted content using the decrypted region key (RCD) and outputs the decrypted content.

摘要： The invention relates to an apparatus for receiving a first and second video signal. The first video signal represents a sequence of images having a first size, and the second video signal representing a sequence of images having a second size, the second size being smaller then the first size of the images. The apparatus combines said first and second video signal so as to obtain a composite video signal suitable for displaying on a display unit. The signal combination means being adapted to combine the first and second video signal while the size of the images corresponding to the second video signal remains unchanged.

摘要： A device is equipped with local storage arrangement such as HDD and a removable optical storage carrier input device. Removable carriers include storage applications that necessitate storage space for storing data items. A storage management unit allocates storage space of the local storage arrangement to the inserted removable optical storage carrier and the application stored therein. The management unit also attributes to the portion identification information respecting access rights granted to the application with respect to data items stored in the allocated portion. The application is given no access to data items stored outside the allocated portion.

摘要： The present invention provides a method and apparatus for playing an optical disc, and an optical disc recording apparatus. According to the method provided by the present invention, the description information of the program content and the description information of the enhancement content are first acquired, and then compared with each other; then it is judged whether the program corresponds to the enhancement content according to the result of the comparison; and finally, the program content is played independently of the enhancement content if the program content does not correspond to the enhancement content. With the present invention, the playback problem causing from the non-match of the program content and the enhancement content in an optical disc with the enhancement format resulting from the revision of the optical disc by a conventional optical disc recording apparatus that does not support the enhancement format can be avoided.

摘要： Current legislation requires the possibility of encryption when storing television programmes received by broadcast. However, legacy playback apparatuses will not be able to play back such encrypted data in a regular way, but possibly in a wrong way. This may result in problems like damage of speakers. Therefore, the application intends to hide any of such possibly damaging streams by intentionally providing such streams with a wrong identification during the encryption process. The application provides among others a method and circuit for encryption and a method and circuit for decryption. The application is especially suitable for DVD recorders, but may also be employed for other video and/or audio recorders. The invention may even be used for encrypting non-audiovisual data.
摘要翻译： 当前立法要求在存储通过广播接收的电视节目时加密。 然而，传统播放设备将不能以常规方式播放这样的加密数据，但可能以错误的方式播放。 这可能会导致扬声器损坏等问题。 因此，应用程序意图通过在加密过程期间有意地提供具有错误标识的这种流来隐藏任何这样的可能有害的流。 该应用提供了加密的方法和电路以及用于解密的方法和电路。 该应用特别适用于DVD刻录机，但也可用于其他视频和/或音频记录器。 本发明甚至可以用于加密非视听数据。

摘要： A device for rendering real time information arranged in cells constituted by units encoded at a variable bit rate, e.g. video on a DVD, is described. The device has various trick play modes for rendering the information at a different speeds based on speed pointers. A limited amount of speed pointers is included in the information stream. The device has a calculation unit 32 for calculating further speed pointers based on estimating the playback time of the units by retrieving cell playback information (C-PBIT) that includes the addresses of the first unit and the last unit within the cell and a cell playback time, retrieving a unit address map (VTS-VOBU-ADMAP) that includes the addresses of the units, determining a number of units within the cell by determining a position of said first and last unit in the unit address map, and dividing the cell playback time by the number of units.
