In a system for receiving a signal containing digital data representing HDTV image information in the form of multilevel symbols formatted into groups of successive fields, each field comprising a field segment, a plurality of data segments, and associated sync components, the received signal is demodulated to produce a demodulated signal. The demodulated signal is comb-filtered to reject NTSC co-channel interference to produce a filtered signal. The filtered signal is trellis decoded with a trellis decoder employing a truncated non-Euclidean metric.
