| Terminología de las notas medias de opinión |
 |
En la Recomendación UIT-T P.800.1 se da la terminología que se utilizará junto con las expresiones de calidad vocal, de video y audiovisual relacionadas con las notas medias de opinión (MOS). Mediante la nueva terminología se pretende evitar malentendidos, por ejemplo si los valores de MOS especificados para una señal de audio corresponden a calidad de escucha, a calidad de habla o calidad de conversación, o si se han obtenido a partir de pruebas subjetivas, modelos objetivos o modelos de planificación de red, así como ampliar el concepto a la calidad de vídeo y audiovisual. Además, la Recomendación proporciona identificadores relacionados con el ancho de banda, el tipo de interfaz (eléctrica o acústica) y la resolución de vídeo. En la Recomendación UIT-T P.800.2 se presentan directrices adicionales para la interpretación de la nota media de opinión (MOS). |
