Abstract

En una implementación, se proporciona una estructura de fijación de parámetro suplementaria ("SPS") que tiene su propio tipo de unidad de capa de abstracción de red ("NAL") y permite la transmisión de parámetros dependientes de capa para capas sin base en un ambiente SVC. La estructura suplementaria de SPS también puede ser utilizada para ver información en un ambiente MVC. En un aspecto general, se proporciona una estructura que incluye (1) información (1410) de una unidad SPS NAL, la información describiendo parámetro para utilizarse en la descodificación de una primera capa que codifica una secuencia de imágenes, y (2) información 1420 de una unidad suplementaria SPS NAL que tiene una estructura diferente a la de la unidad SPS NAL, y la información de la unidad suplementaria SPS NAL describe un parámetro para utilizarse en la descodificación de una segunda capa que codifica la secuencia de imágenes. Se proporcionan métodos y aparatos asociados en los lados de codificador y descodificador, así como para la señal.
