Abstract

"SISTEMA DE TRANSMISSãO PARA TRANSMITIR UM SINAL MULTIPLEX DE UM TRANSMISSOR PARA UM RECEPTOR, RECEPTOR PARA RECEBER UM SINAL MULTIPLEX E DEMULTIPLEXADOR E PROCESSO PARA DEMULTIPLEXAR UM SINAL MULTIPLEX". Em um sistema de transmissão MPEG-2, diversos programas, consistindo cada um de diversas correntes elementares são multiplexados em uma corrente de transporte por um multiplexador (8). A corrente de transporte é transmitida pelos meios de transmissão (10) via meio de transmissão (16) para um receptor (18). No receptor (18), o sinal é desmodulado pelos meios de recepção (12) e demultiplexado pelo demultiplexador (14). No sentido de ser capaz de encontrar as diferentes correntes elementares que formam um programa, diversas tabelas são usadas. As citadas tabelas que podem mudar ao longo do tempo são atualizadas pela informação presente na corrente de transporte. As tabelas são identificadas por um número de versão no sentido de ser capaz de distinguir diferentes versões delas. Os números de versão não são necessariamente números subsequentes. Em uma técnica anterior, a filtragem do sistema de transmissão tem que ser realizada em todos os números de versão possíveis para encontrar atualizações de uma tabela. No sistema de transmissão de acordo com a presente invenção, a filtragem é realizada somente selecionando seções possuindo um número de versão que é diferente dos números de versão prévios.
