Perfiles de accesibilidad para los sistemas de TVIP |
Esta Recomendación define tres perfiles con características de accesibilidad diferenciadas para sistemas IPTV, con niveles crecientes de necesidades en términos de soporte. El perfil básico ofrece una accesibilidad elemental, el perfil principal proporciona la gama más amplia de características y el perfil mejorado ofrece un nivel intermedio entre el perfil básico y el perfil principal. La información para la accesibilidad es del tipo subtítulos, trenes de lenguaje de signos y descripciones de audio que se transmiten por separado de los contenidos de vídeo a los dispositivos terminales IPTV. Al definir los perfiles anteriores, las personas con discapacidad pueden elegir más fácilmente los dispositivos terminales que disponen de las funciones que necesitan. |
