Abstract

Se proporciona un método de decodificación. El método incluye recibir un flujo de bits de video que incluye una unidad de imagen (PU), la PU que incluye una unidad de capa de abstracción de red (NAL) de encabezado de imagen (PH) que tiene un tipo de unidad NAL de encabezado de imagen (PH_NUT) y una unidad NAL de capa de codificación de video (VCL) asociada, el PH_NUT significa que un identificador de capa (ID) de la unidad NAL de PH es igual a un ID de capa de la unidad NAL de capa de codificación de video (VCL) asociada y un ID temporal de la unidad NAL de PH es igual a un ID temporal de la PU; y decodificar una imagen codificada desde la PU para obtener una imagen decodificada.
