Concesión
An encoder for at least partially encoding a 2-dimensional digital image representation into a data stream is shown. The 2-dimensional digital image representation comprises groups of coefficients representing spatial components of the digital image representation, each group comprising at least two coefficients of spatial components, wherein the groups are arranged in a 2-dimensional array. The encoder comprises a processor configured to generate the data stream using differential encoding in accordance with a relevance order of the groups. The processor may signal a stop of encoding if a predefined relevance threshold in the relevance order is reached.
