Abstract

Digital television has become one of the most promising industries. The advanced television system is scheduled to totally replace the current television broadcasting system in the US. In this paper, we present the implementation and discussion of the trellis en/decoder in the grand alliance digital television system proposed by the Advanced Television System Committee (ATSC). In the paper, we use a relatively efficient way to realize the en/decoding circuit. The correctness of our design has also been demonstrated
