SIGNAL TRANSMISSION AND RECEPTION APPARATUS AND SIGNAL TRANSMISSION AND RECEPTION METHOD

摘要

FIELD: information technology. ^ SUBSTANCE: method involves receiving broadcast signals according to a time-frequency slicing (TFS) frame, multiplexed with at least one input stream in the time and frequency domain; deinterleaving the received broadcast signals in the frequency domain; syntax analysis of broadcast signal subjected to frequency deinterleaving with output of a predetermined input stream among the broadcast signals subjected to frequency deinterleaving based on the syntax analysed result; inverse transformation of symbols corresponding to the extracted predetermined input stream into bit data; and performing first error-correction decoding of the inverse transformed bit data based on a low density parity bit scheme. ^ EFFECT: high efficiency of transmitting data. ^ 8 cl, 31 dwg
