Abstract

En un ejemplo, un método para codificar datos de video incluye codificar una o más unidades de capa de abstracción de red (NAL) de capa de codificación de no video (VCL) de una capa de una corriente de bits multi-capa, en donde una o más unidades NAL no-VCL contienen un mensaje SEI Hash de imágenes decodificadas; el método también incluye determinar un conjunto de capas de la corriente de bits multi-capa a la cual se aplica el mensaje SEI Hash de imágenes decodificadas con base en un identificador de capa de una o más unidades NAL no-VCL que contienen el mensaje SEI Hash de imágenes decodificadas.
