A resynchronization method for use in a data communication system having a
first device configured to transmit data at a symbol rate to a second
device. The second device includes a Reed Solomon (RS) decoder having a
RS lock indicator and a Moving Picture Experts Group (MPEG) Protocol
Interface (MPI) having a MPI lock indicator, wherein the RS and the MPI
lock indicators are monitored. Four different states, defined by the
values of the RS and MPI lock indicators, determine whether the data
communication system will wait for the RS decoder and the MPI hardware
block to resynchronize, whether an intermediate-subset of the channel
acquisition algorithm is performed or whether the entire channel
acquisition algorithm is performed. The method for resynchronization
described herein recovers synchronization within a predetermined time
without the layers above the physical link layer having knowledge.
