Error-robust multiplex process with retransmission

A process for transmission of data from data sources by means of data blocks between a transmitting station and a receiving station, said data blocks each having a synchronization pattern field (SYNC), a header field (HEADER) and an information field (INFORMATION), wherein said synchronization pattern field (SYNC) of each of said data blocks indicates a data block beginning, the information field follows the header field and the header field contains control characters for processing the information field (INFORMATION), said process comprising the steps of:

• a) providing a fixed information field (FIXINFO) in each of said data blocks for data for which a delay in transmission due to error correction processes is avoided;
• b) immediately transmitting said fixed information field (FIXINFO) of each of said data blocks to the receiving station without information from the header field and independently of any occurring erroneous transmissions after a receiver-side synchronization for said data block;
• and
• c) testing a remainder of each data block for at least one error within a predetermined error detection range in the receiving station and, when said at least one error is detected within said detection range, performing an error correction only for said remainder of the data block, wherein said remainder of each of said data block does not include the fixed information field (FIXINFO).
