Abstract

''SISTEMA PARA A CONVERSãO DE FORMATO DE DADOS DIGITAIS E GERAçãO DE FLUXO DE BITS'' Um sistema de Conversão (200) intercala e converte dados em uma pluralidade de diferentes formatos de dados de uma pluralidade de fontes diferentes (202, 230), para um formato de dados de saída selecionado para transmissão em um canal de transmissão selecionado. Um método para conversão de formato de dados digitais envolve desfazer a colocação em pacote (210, 240) de um fluxo de dados em pacote de entrada. Um parâmetro de recuperação de sincronização é formado em resposta a um formato de dados de saída desejado (214, 245). Os dados desfeitos da colocação em pacote são novamente colocados em pacote (216, 250) em resposta ao formato dos dados de saída desejado e o parâmetro de recuperação de sincronização é incorporado nos dados novamente colocados em pacote. Os dados novamente colocados em pacote são multiplexados (218) em resposta ao formato selecionado e fornecidos para um canal de saída.
