| Técnicas de medición de la calidad de vídeo por percepción aplicables a la televisión por cable cuando hay una referencia reducida |
En la Recomendación UIT-T J.249 se ofrecen directrices sobre la selección de métodos adecuados para la medición objetiva de la calidad de vídeo percibida en presencia de una señal de referencia reducida. A continuación se presentan algunos ejemplos de aplicaciones que pueden emplear esta Recomendación:
1 Trenes entrelazados de vídeo en redes de clave, incluidos los transmitidos por Internet utilizando IP.
2 Algunos tipos de carga útil de vídeo de televisión por IP (TVIP).
3 Supervisión de la calidad de vídeo en el receptor cuando se dispone de canales laterales.
4 Supervisión de la calidad de vídeo en puntos de medición situados entre el punto de transmisión y el punto de recepción. |
