Abstract

"ESTAçãO TERRESTRE DE SISTEMA DE TELEVISãO VIA SATéLITE POSSUINDO ARQUITETURA DE CONVERSOR/TRANSMISSOR LNB DE MúLTIPLOS CANAIS DE BANDA LARGA COM SINTONIZADOR BRUTO NA UNIDADE EXTERNA". Um sistema terrestre de televisão via satélite, particularmente para um sistema de sinal de televisão via satélite realiza ou pára (make or break), inclui uma unidade externa e uma unidade interna que estão em comunicação uma com a outra através de um único cabo coaxial e um único condutor separado opcional para energia. O sistema terrestre de televisão via satélite opera para medir e reverter os erros de conversão de freqüência utilizando técnicas DSP, permitindo uma geração e transmissão mais precisas de sinais de ligação superior do sistema terrestre de televisão via satélite. Os dados de controle para o sistema são enviados através de uma conexão de taxa de dados baixa em um cabo de energia, ou por um canal de sinalização de banda estreita através de um cabo coaxial. O sistema também utiliza um único oscilador de referência para acionar os vários sintetizadores de freqüência e similares. O sistema terrestre de televisão via satélite utiliza osciladores relacionados para as seções de ligação superior e ligação inferior. O desvio da freqüência transportadora na ligação inferior é medido em uma parte de circuito de rastreamento de transportador de um demodulador de sinal de televisão. O desvio de freqüência transportadora da ligação inferior é utilizado para sintetizar vários sinais de freqüência para as seções de ligação superior e ligação inferior para corrigir os erros de freqüência. Para a seção de ligação superior, o desvio de freqüência transportadora da ligação inferior é revertido na ligação superior. Se a ligação superior estiver em uma freqüência diferente, o desvio medido do oscilador principal de sistema pode ser escalonado por diferentes razões de sintetizador.
