Detailed Description

ATSC trellis encoder building block.

Note this is NOT the 12x interleaved interface.

This implements a single instance of the ATSC trellis encoder. This is a rate 2/3 encoder (really a constraint length 3, rate 1/2 encoder with the top bit passed through unencoded. This does not implement the "precoding" of the top bit, because the NTSC rejection filter is not supported.
