    • Provided are a Vestigial Side Band (VSB) digital television (DTV) receiver based on is A/53 of the Advanced Television System Committee (ATSC) that can secure backward compatibility of a low-ranked DTV receiver by using parity bytes added to robust data for error correction and obtain RS coding gain from the robust data, and a method thereof. The DTV receiver includes: a receiving unit for receiving a transmission signal including general data and robust data and converting the transmission signal into a base-band signal; an equalizer for determining a symbol level of the transmission signal; a trellis decoder for performing trellis decoding on a symbol of the determined level; a nonsystematic Reed Solomon (NRS) decoder for performing NRS decoding on the trellis-decoded robust data and correcting an error; and a restoring unit for restoring a digital video data stream with respect to the trellis-decoded general data and the NRS-decoded robust data.

    • Provided is a Vestigial Side Band Digital Television (DTV) transmitter/receiver based on Advanced Television System Committee A/53. The invention provides DTV transmitter/receiver having a dual stream structure through generation of robust data which has a transmission rate a fourth as fast as that of normal data, and a method thereof. The DTV transmitter includes: input means for receiving digital video data stream including normal and robust data; encoding means for performing ¼ rate coding on the digital video data stream so that one bit can be transmitted through two symbols; and transmitting means for modulating/transmitting output signals of the encoding means. This invention can reduce SNR and satisfy TOV of robust data by performing additional FEC on robust data, transmitting/receiving ¼ rate coded robust data, which are capable of transmitting one-bit data for two symbols, and improving decoding ability of an equalizer and a trellis decoder of a DTV receiver.
