Abstract
The synchronization method, consists in transmitting, in addition to the data: inter-block separators, for separating the data corresponding to separate blocks, each inter-block separator comprising: a fixed radical, a first binary word representing the rank of a block of picture elements associated with this separator, and a second binary word representing the sum of this rank and of the number of events which are encoded by the data corresponding to the block associated with this separator; picture separators, for separating the data corresponding to successive pictures, each picture separator being repeated several times and comprising a fixed radical followed by a binary word indicating the rank of the separator in the repetitions; synchronization patterns at the picture line frequency and synchronization patterns at the picture frequency, transmitted while interrupting the transmission of the data and of the separators. application to the transmission of digital video pictures on an asynchronous channel.
