Abstract

<B>DERIVAçãO DE TELEVISãO A CABO INCLUINDO MODEM<D> Uma derivação (125) para uso em um sistema de televisão a cabo (100) inclui um circuito de derivação convencional (218) para receber um sinal elétrico direto e derivar o sinal elétrico recebido em mútiplos sinais de saída, incluindo informações de televisão, para derivações de assinantes. A derivação (125) também inclui um modem (216) para processar o sinal elétrico recebido para demodulá-lo e deste modo gerar um sinal demodulado que inclui dados. Um empacotador (220), tal como um hub Ethernet, está acoplado ao modem (216) para receber o sinal demodulado e dispor os dados em pacotes de dados para transmissão da derivação (125) para as derivações dos assinantes. Os pacotes de dados podem ser transmitidos para assinantes utilizando as mesmas derivações que são usadas para transmissão das informações de televisão ou diferentes derivações que são dedicadas a fornecer pacotes de dados.
