Abstract
Los presentes principios se relacionan con un decodificador de referencia hipotética (HRD) para una extensión de codificación de video escalable para un algoritmo de compresión. Tal implementación propone modificar el HRD H-264/AVC con el SVC de AVC. Esa implementación define las restricciones de HRD para cada punto de interoperabilidad de SVC. Se describe una implementación en particular, pero son posibles otras implementaciones y se contemplan por los presentes principios. Se muestran los cambios para el escalamiento espacial, temporal y de SNR. También hay cambios con los parámetros HRD relacionados que se muestran. Las diferentes implementaciones mencionadas proporcionan reglas para un HRD para SVC. Por lo menos una implementación propone las reglas SVC-HRD como modificaciones para las reglas AVC-HRD. Un usuario puede utilizar las reglas SVC-HRD propuestas para construir un SVC-HRD y probar una corriente de bits para la compatibilidad de SVC.
