Abstract

"APARELHO PARA RECEPçãO DE RADIO DIFUSãO DIGITAL". Um aparelho é provido para recepção de radiodifusão digital realizando processamento reverso para processamento de sinal realizado em um lado de radiodifusão sobre um sinal recebido de uma radiodifusão terrestre digital e suscetível de reproduzir corretamente dados fonte de informações contidos nos sinais de radiodifusão. Um valor inicial em um circuito de geração de seq³ência aleatória é definido de acordo com números de um canal e sub canal a ser recebido, uma seq³ência binária pseudo aleatória (PRBS) é gerada por um circuito de geração de seq³ência aleatória (12) baseado sobre este, um circuito de detecção de erro de sinal piloto (9) detecta erros de portadoras dos sinais piloto CP e SP desmultiplexados por um sinal desmultiplexador de sinal (7) utilizando a PRBS, distorção de uma portadora de uso de transmissão de informações ocorrendo em um canal é corrigida por um circuito de equalização (8) de acordo com a mesma, e um circuito decodificador de sinal de controle de transmissão (10) detecta uma fase de referência da portadora de um sinal de controle de transmissão TMCC utilizando a PRBS, decodifica o TMCC de acordo com aquela, fornece a mesma a um circuito de controle (11) para gerar um sinal de controle requerido, e dessa maneira controla a reprodução dos dados fonte de informação.
