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 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 decoded 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 of resynchronization described herein
recovers synchronization within a predetermined time without the layers
above the physical link layer having knowledge.
