Abstract
A system and method for encoding via a trellis encoding scheme a digital data stream. The system and method finds particular application in the trellis encoding scheme used in the Grand Alliance digital television specification. In the system and method, a series of registers is used to cycle the digital bytes (or words) currently being interleaved and trellis encoded. A multiplexer selects the appropriate nibble of the data words for encoding during each cycle of the registers.
