Hoffman ha reflexionado sobre las expectativas que los espectadores tienen de la UHD afirmando que el uso de pantallas de gran formato no solo servir para visualizar im genes en ultra Alta sino tambi n para poder seguir en modo multipantalla varias se ales simult neamente.

Los consumidores est n comprando ya hoy televisores 4K de forma cada vez m s generalizada, los eventos internacionales que se producen en 4K son cada d a m s numerosos, y plataformas como BT Sport, Sky, Netflix, Amazon est n desarrollando ya estrategias para UHD. Sin embargo, los broadcasters p blicos necesitan definir con urgencia sus estrategias ante este gran cambio , ha afirmado.

Por otro lado, la puesto en el punto de mira el impulso que podr a significar la emisi n de los Juegos Ol mpicos de Tokio 2020 en 8K con alto rango din mico.

A su juicio, el alto rango din mico (HDR) y alto frame rate (HFR), junto con una metodolog a de evaluaci n correcta de estos par metros, podr n elevar la Ultra Alta Definici n a un nuevo nivel.

Por ltimo, ha subrayado que en estos nuevos entornos el audio es tan importante como el v deo en este caso, el audio multicanal basado en objetos jugar un papel relevante . Hoffman ha concluido su intervenci n subrayando que como suele ser habitual en todos los cambios tecnol gicos el rey sigue siendo el contenido .
