A system converts an input data stream in a first format (identified by a first stream code having at least two bits) into an output data stream in a second format. The system includes, among other things, a data sequencer for sequencing the input data stream and a counter. The sequencer includes a select input having a first number of selection input locations, a data input for receiving the digital data stream, and output for transmitting the output data stream. The counter includes the first number of selection outputs. A first logic element and a second logic element are coupled to a number of the selection inputs of the sequencer and a number of the selection outputs of the counter. The first and second logic elements control the data sequencer such that the input data stream in converted into the second format.
