Abstract
The invention proposes a method and a device for arithmetic encoding of a current spectral coefficient using preceding spectral coefficients. The preceding spectral coefficients are already encoded, and both the preceding and current spectral coefficients are comprised in one or more quantized spectra resulting from quantizing a time-frequency-transform of video, audio or speech signal sample values.
