摘要： The invention relates to a device for the scalable coding of a spectrum of a signal comprising audio and/or video information. The spectrum comprises binary spectral values which are grouped into bands. Said device comprises a device (102) for producing a first partial scaling layer and a second partial scaling layer and a device (106) for forming the coded signals in order to incorporate the first partial scaling layer and the second partial scaling layer into the coded signal, such that the first and the second partial scaling layer can be decoded separately from each other. A partial scaling layer exclusively comprises, in comparison with a full scaling layer, bits of a defined order of part of the binary spectral value in the band such that additional decoding of a partial scaling layer can provide a finely controllable and finely scalable precision gain.

摘要： The invention relates to a method for generating a second data stream from a first data stream containing a first start block and a first user data block comprising user data. According to said method the first start block is extracted (116) from the first data stream. Next the second start block for the second data stream is generated (118), after which at least a part of the first start block, which part contains information making it possible to trace the origins of the user data, is integrated (120) into the second start block. Finally the second user data block containing the same user data is generated (122) so that a complete second data stream can be obtained. The method provided for by the invention allows for the device-specific encoding of user data, makes it possible to obtain a flexible device-specific copy for other devices of a user and, notably, provides complete references as to the origins of a copy, which in turn permits effective copyright protection.

摘要： The invention relates to a method for generating an encoded multimedia data stream, according to which first a start block (12) and then a user data block (14) are generated. The initial segment (20) of the user data block (20) contains unencoded user data which are followed by encoded user data (16). In this way a preview or prelist function can be implemented in a simple manner. In addition, a playback device can already play back the unencoded initial section (20) while the complete start block is being processed so as to obtain a multimedia data key for generating hash totals, etc. The above parallel processing makes it possible to use playback devices with limited storage and processing resources without having to accept excessively long delays.
