ABSTRACT:
Still and moving picture components of a motion video transmission are coded by using the same algorithm. The system provides a posteriori recognition of still pictures on memorization of the quantization step used to code groups of pixels of a still picture which belong to a certain hierarchical level (e.g. the macroblock level), and allows convergence of the quantization step towards a minimum predetermined value.
