Abstract

"INSERçãO DE DADOS AUXILIARES EM UM FLUXO DE DADOS DE TRANSPORTE" Um dispositivo digital, tal como um VTR digital, recebe e grava um fluxo de dados compatível com o MPEG. Na reprodução, o DVTR insere (32) informação auxiliar em pacote, tal como informação de exibição na tela, no fluxo de dados de transporte (30) para transmissão para um outro dispositivo digital, tal como um receptor de televisão. As impressões de tempo no fluxo de dados compatível com o MPEG não são afetadas pela inserção da informação auxiliar. O DVTR VSB modula (13) o fluxo de dados para produzir largura de faixa suficiente para a informação auxiliar no fluxo de dados.
