Abstract

Se describe un mecanismo de codificación de video. El mecanismo incluye recibir un flujo de bits que comprende un conjunto de parámetros de imagen (PPS) en una unidad de capa de abstracción de red (NAL) PPS y una imagen codificada que comprende un conjunto de unidades NAL de capa de codificación de video (VCL). Una unidad NAL VCL en particular no se refiere a la unidad NAL PPS a menos que el valor de un identificador de capa de encabezado de unidad (nuh_layer_id) NAL de la unidad NAL PPS sea menor o igual que el valor de un nuh_layer_id de la unidad NAL VCL en particular. La imagen codificada se decodifica a partir del conjunto de unidades NAL VCL basado en el PPS en la unidad NAL PPS para producir una imagen decodificada. La imagen decodificada se reenvía para su visualización como parte de una secuencia de video decodificada.
