Abstract

"SISTEMA PARA MULTIPLEXAçãO DINâMICA DE FLUXOS DIGITAIS". A invenção diz respeito a um método para multiplexação dinâmica de fluxos digitais que são transmitidos na forma de unidades de fluxo em um canal, cada uma das ditas unidades de fluxo levando um identificador de fluxo que pode ser usado para associar o mesmo com o fluxo digital correspondente. A alocação de um identificador a um fluxo digital é definida por uma tabela de alocação e pode variar com o tempo, de uma maneira tal a permitir multiplexação dinâmica. De acordo com, a tabela de alocação supramencionada leva um número da versão e, a fim de indicar que uma alteração na versão da tabela de alocação se aplica a um dado fluxo digital, uma seq³ência de sinais é transmitida com pelo menos uma unidade de fluxo de alteração da versão compreendendo o identificador atual do dito fluxo digital, um indicador que pode ser usado para determinar se a unidade de fluxo é uma unidade de fluxo de alteração da versão e o número da versão tornando-se aplicável ao dito fluxo digital.
