Abstract:
A process for data transmission between two stations by means of data blocks assembled in data packets, each of said data blocks having a synchronization pattern field (SYNC), a header field (HEADER) and an information field (INFORMATION) following the header field, wherein the synchronization pattern fields (SYNC) indicate a beginning of the respective data packets and the header field (HEADER) of each of said data blocks contains control characters for processing the information field following the header field, said process comprising the step of providing a header control field (HEX) following the header field (HEADER) in each of the data blocks for reconstruction of the header field when a transmission of the header field contains errors, and providing a number (z) of bits in the header control field (HEX) for encoding information regarding a possible header field change from one data packets to a subsequent data packets.
