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 present invention relates to a storage device, a storing method and rewritable record carrier for storing data file, wherein a rewriting frequency of the date files is identified and the data files are classified based on their identified rewriting frequency. Each data file is then written using a rule selected according to the result of classification. The definition of the allocation class and rules based on the rewriting frequency enables an optimization of the file storage for endurance and power consumption. Thereby, the life time of the storage medium and the battery life of the whole system can be extended.

摘要： The present invention relates to a record carrier, drive device and method of reading from or writing to the record carrier, wherein a predetermined navigation area (DN) is provided on said record carrier for storing at least one predetermined parameter specifying at least one of a logical format and an application format used on said record carrier. Thereby, a universal portable disc format can be provided, where a single disc can contain content in many formats from many different devices and all these content types can coexist. A clean separation of physical, logical and application level structures is thus possible without loosing any flexibility or ability of drive devices to maintain these structures.

The apparatus comprises input (1) means for receiving video data signals, generating means (100) for generating characteristic point information signals, processing means for processing the characteristic point information signals for a plurality of characteristic points into a sequence of characteristic points information signals (CPI) and writing means (108) for writing the sequence of video data signals and the sequence of characteristic points information signals on the record carrier (3). The characteristic point information signals identify a characteristic point in the sequence of video data signals. Various measures are proposed in relation to the CPI aiming at providing compact way of storing information related to a size of I-pictures.

摘要： An allocation and caching method and apparatus for speed-up of interactivity from storage media. When running an interactive presentation, the user is presented with a choice of presentation paths. The respective initial parts of these possible paths are decoded and cached before the user chooses one subsequent path through interaction in a decision D. The subsequent path is immediately replayed from the fast cache memory. Jumping to the chosen path on the storage medium is slower and takes place while the cached data is being presented. When the path from the storage medium is accessed, playing is subsequently continued from the storage medium until the next interactive decision appears. Hence, no time is lost after making a decision D.
摘要翻译：一种用于从存储介质加速交互性的分配和缓存方法和装置。在运行交互式演示文稿时，用户可以选择演示文稿路径。在用户在决策D中通过交互选择一个后续路径之前，对这些可能路径的各个初始部分进行解码和高速缓存。随后的路径立即从高速缓存存储器重播。跳到存储介质上选定的路径较慢，并且在缓存的数据正在呈现时发生。当访问存储介质的路径时，随后从存储介质继续播放，直到出现下一个交互决定。因此，做出决定后不会浪费时间D.

摘要： Method of recording a series of ordered real-time information signals, such as audio/video information, on a disc like recording medium, such as an optically readable disc. The method comprises recording of contiguous sequences of detectable marks, each sequence representing a successive series of information signals of an A/V program, in a distributed manner across the recordable area of the disc like recording medium. Between the recorded sequences, preferably free space remains available for recording contiguous sequences of information signals of another A/V program in a same distributed manner. In an embodiment, a logical address space is divided in successive allocation areas, each allocation area used for subsequently recording a specific sequence of an A/V program.

摘要： A method of storing a substantially real time stream of information signals arranged in separate, consecutive data packets of digital format on a disc like record carrier. A new stream pack (S-PCK) is defined comprising a pack header and a multiple of source packets containing said data packets with corresponding added time stamps related to a time of arrival of said data packets. The pack header comprises data packet retrieval information, such as the number of new source packets in the stream pack and the effect of the start location of the first source packet in the stream pack. Preferably private stream (2) of the MPEG-format is employed for this new stream.
