Abstract

Patente de Invenção <B>"SISTEMA DE TELEVISãO DIGITAL MULTICANAL"< D>. Um sistema de televisão digital incluindo um meio de transmissão (4, 6) para transmitir informações audiovisuais digitais em uma pluralidade de canais (41), caracterizado pelo fato de que compreende ainda um meio (44, 45) para introduzir em tempo real uma mensagem de evento concernente a uma difusão de evento ao vivo em pelo menos um canal no fluxo de dados de pelo menos um outro canal, a mensagem de evento incluindo informações relativas à ocorrência de um evento e ao canal no qual o evento ocorreu. De preferência, o meio de transmissão inclui ainda um dispositivo de retardo (3) para introduzir um retardo predeterminado no tempo de transmissão das informações audiovisuais difundidas em cada um dos canais. A invenção encontra aplicação particular no caso de transmissão simultânea de eventos esportivos, quando um espectador assistindo um canal pode ser informado da ocorrência de um evento, tal como um gol, em outro canal.
