| Terminología de las notas medias de opinión |
En esta Recomendación se describe una terminología que se utilizará junto con las expresiones de calidad vocal, de vídeo 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 vocal 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 la anchura 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). |
