Dispositivos terminales de TVIP: Modelo básico

En la Recomendación UIT-T H.721 se describen y especifican las funcionalidades de los dispositivos terminales TVIP para los servicios TVIP básicos definidos en la Recomendación UIT-T H.720. Esta Recomendación está dedicada a los dispositivos terminales TVIP con capacidad para recibir servicios de televisión lineales y servicios de vídeo a la carta, además de contenido de datos (como texto) utilizando una red de entrega de contenido gestionada. La definición de servicio tiene en cuenta las condiciones de la entrega del contenido, como la QoS. Los tipos previstos de dispositivos terminales TVIP son los descodificadores y televisores digitales con capacidades TVIP incorporadas.
