Abstract
"PORTADOR DE INFORMAçãO, DISPOSITIVO E PROCESSO PARA CODIFICAçãO, E, DISPOSITIVO E PROCESSO PARA DECODIFICAçãO" A invenção refere-se a um portador de informação que compreende marcadores de comprimento de processamento limitadas em uma trilha. Os comprimentos de processamento dos marcadores representam bits de canal principal a variação de um parâmetro adicional dos marcadores representando bits de canal secundário. Nem todos os marcadores tem as ditas variações, somente marcadores de pelo menos um comprimento de processamento tem as ditas variações. A invenção refere-se adicionalmente a um dispositivo para codificar, um processo de codificação, um dispositivo para codificar e um processo de descodificação.
