Abstract

<B>SISTEMA DE TELEVISãO A CABO PARA TRANSMITIR DADOS NãO-MODULADOS<D> Um sistema de televisão a cabo (100) que compreende um transmissor (105) para transmitir um sinal de avanço compreendendo um primeiro sinal com informações em uma primeira faixa de freq³ência e um segundo sinal com dados de banda base transmitido em uma segunda faixa de freq³ência. Um nodo (120) recebe o sinal de avanço e divide o primeiro sinal do segundo sinal, e um centro de processamento de dados (255), tal como um centro de Ethernet, processa o segundo sinal para arrumar os dados da banda base em pacotes de dados. De forma subseq³ente, o primeiro e segundo sinais são recombinados como um sinal de avanço que é transmitido adiante dentro do sistema de televisão a cabo (100). Pelo menos uma derivação (125) é incluída no sistema (100) para dividir uma porção do sinal de avanço para prover as informações e os dados de banda base em canais de assinante (336) da derivação (125).<B> CABLE TELEVISION SYSTEM FOR TRANSMITTING NON-MODULATED DATA <D> A cable television system (100) comprising a transmitter (105) for transmitting a forward signal comprising a first signal with information in a first range of frequency and a second signal with baseband data transmitted in a second frequency range. A node (120) receives the forward signal and splits the first signal from the second signal, and a data processing center (255), such as an Ethernet center, processes the second signal to pack the baseband data into packets of data. Subsequently, the first and second signals are recombined as a forward signal that is transmitted ahead within the cable television system (100). At least one branch (125) is included in the system (100) to divide a portion of the lead signal to provide baseband information and data on subscriber channels (336) of the branch (125).
