ABSTRACT:
A transmission system includes a first forward error correction unit, a robust processor unit, a trellis encoder unit, a second forward error correction unit, and a transmitter device. The first forward error correction unit encodes packets belonging to robust and normal bit streams. The robust processor unit receives the encoded robust packets and processes the robust packets to generate the robust bit stream. The trellis encoder unit produces a stream of trellis encoded data bits corresponding to bits of the normal and robust bit streams by mapping encoded data bits of the robust packets into symbols according to one or more symbol mapping schemes. The second forward error correction unit reads in only packets of the robust bit stream and enables generation of parity bytes only for the robust packets. The transmitter device transmits the robust bit stream over a communications channel to a receiver device.
