Abstract

Se describen métodos, sistemas y sintaxis de flujo de bits para el procesamiento restringido en la codificación de video. Utilizando uno o más elementos de sintaxis y cualquier señalización explícita o implícita, un codificador puede señalar decodificadores compatibles que ciertas características del perfil principal, como subimágenes y la codificación escalable multicapa, están deshabilitadas.
