Abstract

TRANSMISSOR DE TELEVISãO DIGITAL PARA CODIFICAR PACOTES PRINCIPAIS E OTIMIZADOS PARA TRANSMISSãO, MéTODO DE CODIFICAçãO DE PACOTES DE DADOS PRINCIPAIS E OTIMIZADOS EM UM TRANSMISSOR DE TELEVISãO DIGITAL, RECEPTOR DE TELEVISãO DIGITAL E MéTODO PARA DECODIFICAR UM SINAL EM UM RECEPTOR DE TELEVISãO DIGITAL, apresenta um pré-processador para pré-processamento dos pacotes de dados otimizados por codificação dos pacotes de dados otimizados para correção de erro à frente (FEC) e expansão dos pacotes de dados codificados por FEC; um formatador de dados adiciona os primeiro dados nulos nos primeiros suportes de local dentro de cada pacote de dados otimizados pré-processados; um primeiro multiplexador multiplexa os pacotes de dados principais com os pacotes de dados otimizados com os primeiros dados nulos; um insersor de suporte insere os segundos dados nulos nos segundos suportes de local dentro de um pacote de dados otimizados transmitido do primeiro multiplexador; um interleaver de dados substitui os segundos dados nulos pelos dados de paridade. Um gerador de dados gera pelo menos uma seqüência de dados conhecida; um processador de símbolo substitui os primeiros dados nulos incluídos em uma saída do interleaver de dados pela(s) seqüência(s) de dados conhecida(s); um codificador não-sistemático RS gera os dados da paridade através da realização de codificação por RS não-sistemática em uma saída do processador de símbolo, e fornece os dados de paridade ao interleaver de dados.
