Abstract
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.
