Abstract

Se divulga un método, un aparato y un producto de programa informático para la codificación y decodificación de vídeo. De acuerdo con una realización, el método de codificación comprende concluir que una secuencia de vídeo codificada se inicia en una posición particular en un flujo de bits, en donde la secuencia de vídeo codificada es una secuencia de imágenes codificadas en orden de decodificación que se puede decodificar independientemente y es seguida por otra secuencia de vídeo codificada o el final del flujo de bits, y en donde el flujo de bits comprende unidades de acceso, y una unidad de acceso comprende datos de vídeo codificados para una única instancia de tiempo y otros datos asociados, y una unidad de acceso comprende una o más unidades de capa de abstracción de red (NAL); e indicar en un delimitador de unidad de acceso que se traten la unidad o unidades de NAL asociadas con el delimitador de unidad de acceso como un inicio de una secuencia de vídeo codificada.
