摘要: Unequal error protection is provided for an HDTV signal by separately coding each one of the classes information in using a conventional coded modulation scheme and then time-division-multiplexing various outputs transmission. In particular, class 4-dimensional 8-state trellis code uniformly-spaced (QAM) constellation.
