Abstract:
1. An apparatus for scalable encoding of a spectrum of a signal including audio and/or video information, with the spectrum comprising binary spectral values, the apparatus comprising: a generator for generating a first sub-scaling layer using bits of a certain order of a first number of the binary spectral values in a band, with the first number being greater or equal to “1” and less than a total number of the binary spectral values in the band, and for generating a second sub-scaling layer using bits of the certain order of a second number of the binary spectral values, with the generator being implemented so as to select the second number of the binary spectral values, such that the number is greater than or equal to “1” and less than the total number of the binary spectral values in the band, and to further determine the second number of the spectral values, such that the number comprises at least one binary spectral value which is not contained in the first number of binary spectral values; and a Means for forming an encoded signal, with the means for forming being implemented so as to include the first sub-scaling layer and the second sub-scaling layer into the encoded signal such, that the first and the second sub-scaling layer are separately decodable from each other.
