Abstract
According to the invention, there are provided sets of contexts specifically adapted to encode special coefficients of a prediction error matrix, on the basis of previously encoded values of level k. Furthermore, the number of values of levels other than 0 is explicitly encoded and numbers of appropriate contexts are selected on the basis of the number of spectral coefficients other than 0.
Claims10
Method for video coding with the procedural steps:
- Provision of a prediction error matrix;
- Conversion of the prediction error matrix by coefficient sampling into a series of symbols;
- Performing context-adaptive arithmetic encoding of the symbols on the basis of symbol frequencies, for which the distribution is selected depending on an already encoded symbol.
