Abstract
An apparatus and method for encoding a signal are provided. The apparatus and method of the present disclosure identify the various portions, or bytes, of an incoming packet in a Reed-Solomon (RS) encoded packet as either data bytes, RS parity bytes, or trellis reset synchronization bytes. The data bytes are passed through without change. The trellis reset bytes are provided to a trellis encoder to determine new byte reset values. These new values are then stored and later retrieved when needed and used to modify the appropriate incoming parity bytes. The new incoming parity bytes are computed using the new trellis reset byte values multiplied by, or added to, a weighting value retrieved from a table stored in memory based on a location of the parity byte and a location of the trellis reset byte in the RS encoded packet.
