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： In order to convert a first and second block of discrete values into a transformed representation, the first block is transformed (102) according to a first transformation rule, after which it is rounded (104). The rounded transformed values are subsequently summed up (106) with the second block of original discrete values in order to then process (108) the summation result according to a second transformation rule. The initial values of the transformation are, in turn, rounded (110) using the second transformation rule, and are subsequently subtracted (112) from the original discrete values of the first block of discrete values in order to obtain a block of integer initial values of the transformed representation. By using this multi-dimensional lifting schema, a lossless integer transformation is achieved that, by employing the same transcription rules, can, however, be undone with inverted signs during the summation or subtraction so that an inverse integer transformation can also be achieved. In comparison to dividing a transformation in rotations, a distinctly reduced computational complexity is achieved and an accumulation of approximation errors is avoided.
摘要翻译：为了将第一和第二离散值块转换成变换后的表示，第一块根据第一变换规则变换（102），然后取整（104）。之后，将经过舍入的经变换的值与第二块原始离散值（106）相加，然后根据第二变换法则（108）处理求和结果。使用第二变换规则的变换的输出值再次被舍入（110），然后从第一离散值块（112）的原始离散值中减去（112）以获得变换后的表示的整数输出值的块。这种多维提升方案实现了无损整数变换，通过应用相同的变换规则可以撤消整数变换，但是在加法或减法中颠倒了符号，从而也可以实现逆整数变换。与将变换分解为旋转相反，一方面实现了显着降低的计算复杂度，另一方面避免了近似误差的累积。
