ABSTRACT:
The invention relates to a method for synchronizing a transmitter memory area in a transmitter memory in a transmitter apparatus with a receiver memory area in a receiver memory in a receiver apparatus, and to a receiver apparatus. The transmitter memory area stores transmission data as transmission-data packets and the receiver memory area stores received data as received-data packets with associated error status data which respectively indicate an error status for the received-data packets. Before a reference identification is generated in the receiver apparatus, which, following transmission using a feedback message in the transmitter apparatus, is used for memory area synchronization, the error status data for a plurality of the received-data packets are checked in the receiver apparatus until a first received-data packet is ascertained for which the error status data indicate no error status. An identification which identifies the first received-data packet is used to ascertain an identification for the current reference received-data packet taking into account a predetermined formation rule for forming the identifications for the received-data packets, from which identification the reference identification for the current reference received-data packet is derived.
