Abstract

A digital broadcasting transmission system and method thereof. The digital broadcasting transmission system, comprises an RS encoder to encode a dual transport stream (TS) which includes a normal stream and a plurality of turbo streams multiplexed together, an interleaver to interleave the encoded dual TS, a turbo processor to detect the turbo streams from the interleaved dual TS and to encode the detected turbo stream, and a trellis encoder to pseudo2 (P-2) vestigial sideband (VSB) code the turbo-processed dual TS, and, then, to perform trellis encoding, and a main multiplexer (MUX) to multiplex the trellis-encoded dual TS by adding a field synchronous signal and a segment synchronous signal thereto.

Description

technical field [0001] An aspect of the present invention relates to a digital broadcast transmission system and method thereof. More particularly, an aspect of the present invention relates to a digital broadcast transmission system and method thereof, which achieve improved reception performance by encoding a turbo stream using various methods. Background technique [0002] Based on the Advanced Television Systems Committee (ATSC) digital vestigial sideband (VSB) technology, the terrestrial digital broadcasting system originating in the United States uses a single carrier and a field synchronous signal in 312-segment units. This system has poor reception performance especially in poor channels such as Doppler fading channels. [0003] figure 1 is a block diagram of a conventional ATSC VSB broadcast sending device, figure 2 shown in figure 1 The frame structure of the data used in the system. [0004] More specifically, figure 1 Shown is an EVSB system that generates...
