Abstract

A first number of system bits together with given information bits form a coherent block. The second number of different system bits consists of blank bits without any information meaning. At most the first sytem bits are used for frame synchronisation, and these system bits ensure the block position recognition and/or synchronisation of an error correction device. The first system redundant bits used for frame synchronisation form a coherent synchronisation word preceding the given information bits, and the synchronisation word position recognition is used for speed balancing in the total flow, when strict synchronisation between the sender and transmission fails. Then the number of blank bits is changed.
