Verbesserungen von Systemen zur Hybrid-Kodierung eines Videosignals.
摘要
The invention allows still and moving picture components of a motion video transmission to be coded by using a same algorithm. The invention is based on aposteriori recognition of still pictures and on a 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 it allows convergence of the quantization step towards a minimum predetermined value. <IMAGE>
