Abstract

Un valor de nuevo cálculo de POC es recuperado por un decodificador (100, 200, 300, 400) a partir de una representación codificada de una imagen RAP (12) en una capa de base (10) de un flujo de video (1) que comprende imágenes (12, 4, 16, 22, 24, 26) en capas múltiples (10, 20). Los valores de POC de imágenes de referencia (24) en una DPB (110, 430) del decodificador (100, 200, 300, 400) se vuelven a calcular usando el valor de nuevo cálculo de POC. Mediante la señalización del valor de nuevo cálculo de POC en la imagen RAP (12), que permite que el decodificador (100, 200, 300, 400) maneje correctamente flujos de video (1) con imágenes RAP no alineadas (12).
