ABSTRACT:
Variable rate data is reformatted for communication to an external device at a fixed rate. Fixed length packets of the variable rate data are recovered from a multiplex of data packets. A packet start byte is added to the beginning of each of the recovered packets. Fill bits are added to the recovered packets as necessary to maintain the desired fixed output rate if the output rate is greater than an information rate of the variable rate data. The recovered packets with the added packet start byte and fill bits are provided as output to the external device at the fixed rate. The recovered packets with the added packet start byte and fill bits are advantageously encoded using alternate mark inversion (AMI) and binary eight zero substitution (B8ZS). The packet start byte and B8ZS substitution can comprise unique AMI violation sequences.
