digital data transmitter for main data coding and optimized for transmission and main data processing method and optimized for transmission on a digital television transmitter

摘要

"DIGITAL TELEVISION TRANSMITTER FOR MAIN AND OPTIMIZED DATA CODING FOR MAIN AND OPTIMIZED DATA PROCESSING METHOD FOR A DIGITAL TELEVISION TRANSMITTER", a digital TV transmitter / receiver method (DTV processing method) data on the DTV transmitter / receiver are revealed; in the DTV transmitter, a preprocessor preprocesses the optimized data by encoding the error corrected (FEC) optimized data and expanding the FEC encoded optimized data; A data formatter generates optimized data packets, including preprocessed optimized data, and inserts known data into at least one of the optimized data packages. A first multiplexer multiplexes optimized data packets with main data packets, including the main data; and an RS encoder encodes the multiplexed master and optimized data packets by RS, the RS encoder adds systematic parity data to each master data packet and adds the RS parity space markers to each optimized data packet; At present, the RS encoder may insert non-systematic RS parity data or null data into the RS parity space markers included in each optimized data packet.
