| Metodología subjetiva de prueba para evaluar la repercusión del retardo de la carga inicial sobre la calidad percibida |
En la Recomendación UIT-T P.917 se define un procedimiento para realizar estudios de comportamiento destinados a investigar la calidad de la transmisión secuencial de vídeo y su relación con la calidad percibida (QoE) por el usuario. Los estudios se realizarán en entornos controlados. Los sujetos están expuestos a diferentes condiciones iniciales de retardo de carga y otras degradaciones de calidad típicas de la transmisión secuencial de vídeo, y se les puede pedir que califiquen la calidad audiovisual o su experiencia. Además, se puede investigar su comportamiento en caso de largos tiempos de carga (por ejemplo, abortar la reproducción del vídeo durante su fase de carga). |
