Abstract
"MELHORIA DA QUALIDADE DE VìDEO POR TRANSMISSãO ESCALONADA EM MODO ROBUSTO". Descreve-se um processo e aparelho para transmissão escalonada de um sinal representativo de conteúdo, tendo um primeiro elemento e segundo elemento, que inclui o seguinte. Um primeiro sinal é codificado representando o primeiro elemento do sinal representativo de conteúdo, e um segundo sinal é codificado representando o segundo elemento do sinal representativo de conteúdo. Um sinal composto é gerado, contendo os primeiro e segundo sinais codificados, com tempo escalonado. Os primeiro e segundo sinais codificados são extraídos do sinal composto, e erros detectados nos primeiro e segundo sinais codificados e extraídos. Se um erro for detectado em um dos primeiro e segundo sinais codificados e extraídos, então o outro dos primeiro e segundo sinais codificados e extraídos é decodificado para reproduzir o elemento correspondente do sinal representativo de conteúdo. De outra forma, os primeiro e segundo sinais codificados e extraídos são decodificados e combinados, para reproduzir o sinal representativo de conteúdo.
