Sending apparatus and method of digital broadcasting system

Abstract

The invention discloses a digital broadcast system transmission device and a sending method thereof, wherein, the transmission device comprises: a first outer encoder and a second outer encoder, executing coding on a first input TS stream and a second input TS stream respectively; a first outer interleaver and a second outer interleaver, executing interleaving on the coded data of the first outer encoder and the second encoder respectively; a first inner encoder and a second inner encoder, executing coding on the interleaved data of the first outer interleaver and the second outer interleaver respectively; an inner interleaver comprising a bit-interleaver, used for executing bit interleaving on the coded data of the first inner encoder and the second inner encoder by a convolution interleaver; a symbol interleaver, used for applying N sets of interleaving addresses to carry out symbol interleaving on the bit-interleaved data of the bit-interleaver; a modulation unit, used for carrying out digital modulation to the interleaved data of the inner interleaver and sending the data. Therefore, by means of improving the randomicity of the symbol interleaver, more effective error correction coding performance is acquired.

Description

[0001] This application is a divisional application of the patent application with the filing date of May 9, 2003, the application number being 03123479.8, and the patent application entitled "Digital Broadcasting System Transmission Device and Method". Technical field [0002] The present invention relates to a transmitting device and method of a digital broadcasting system, and more particularly, to a digital broadcasting system and method capable of improving the randomness of an inner interleaver. Background technique [0003] Compared with analog broadcasting, digital broadcasting uses a digital coding system, which has the advantages of system integration and interactive operation. Therefore, with the help of computers and networks, digital broadcasting meets the requirements of the so-called media concentration center. In addition, the interactive features of digital broadcasting have also made great progress compared with unidirectional analog broadcasting. [0004] In ord...

Problems solved by technology

However, when a burst error beyond the error correction capability occurs, the receiver cannot perform error correction using the error correction code

This leads to the problem of deterioration of reception performance
