<p>A method and apparatus for re-synchronization of serial data blocks (13,17) utilizing recorded re-synchronizing signals (15a,15b,...,19a,19b,....) separating sub-blocks (13a,13b,...,17a,17b,....) of data is provided. Use of the re-synchronization signals (15a,15b,...,19a,19b,....) in combination with error correction codes allows the recovery of data lost due to a signal drop-out even when clock synchronization is also lost. The optimum re-synchronization mark comprises a unique key (40) having a header (44) of two b bits preceding the key and a trailer (42) of b bits appended to the key where b is the maximum correctable number of bits slipped that the clock can be out of synchronization with the beginning of a data sub-block.</p> |
