Abstract
Se proporciona un proceso para determinar la selección de filtros y muestras de entrada para codificación de video escalable. El proceso proporciona re-muestreo que utiliza datos de video obtenidos de un proceso de codificador o decodificador de una capa base (BL) en un sistema multicapa para mejorar la calidad en codificación de video de alta eficiencia, escalable (SHVC). A fin de proporcionar una mejor alineación entre capas, se propone que se señalicen parámetros de ajuste de compensación de capa de referencia.
