Abstract
em várias implementações, são aqui descritas técnicas para resolver problemas relacionados com a localização de uma unidade nal eob em um arquivo de mídia de base da iso. em várias implementações, essas técnicas incluem flexibilizar o requisito de que um arquivo inclua apenas uma unidade nal eob. essas técnicas incluem ainda a provisão da unidade nal eob a partir da camada mais alta quando da reconstrução do fluxo de bits. essa unidade nal eob pode ser adicionada a uma última unidade de acesso no fluxo de bits reconstruído. quando a unidade nal eob a partir da camada mais alta não estiver presente, uma unidade nal eob a partir de uma camada mais baixa pode ser provida em lugar da mesma.
