A Methodology for User Interface Adaptation of Multi-Device Broadcast-Broadband Services

Abstract

New audiovisual experiences involve consuming several contents displayed through multiple internet-connected devices. The TV is still the central hub of the living room, but it is often used simultaneously with other screens. Consequently, the user has the chance to consume all different contents at once across multiple devices. However, no existing adaptation models are available to dynamically adapt such a multitude of contents in multi-device contexts. To address this gap, this paper proposes a novel multi-device adaptation methodology to build adaptive User Interfaces for multi-screen hybrid broadcastbroadband TV experiences. The methodology is extensible to any kind of content, device and user, and is applicable to different contexts considering technological evolution and other fields of application. The proposed methodology is the outcome of extensive research that arose from a previous multi-device media service deployment with broadcasters.

A New 5G Cellular Broadcasting Approach: Hybrid LDM-NOMA and FeMBMS-OMA Analysis Based on Stochastic Geometry

“…Incompatibility and contradiction in digital terrestrial television broadcasting (DTTB) infrastructure have been a historical challenge in cellular broadcast technology for BSP and mobile recipients. There was incompatibility in the 3G technology era for wide band code division multiple access against digital video broadcasting handheld in broadband and broadcast, respectively [10], [11].…”

Especificación, implementación y evaluación de soluciones de sincronización multimedia híbrida (broadcast/broadband) e inter-destinatario para posibilitar nuevas experiencias televisivas enriquecidas, personalizadas, inmersivas y compartidas.

“…Plataforma extremo-a-extremo para la generación, distribución y consumo sincronizado de contenidos híbridos, incluyendo contenidos omnidireccionales y efectos multisensoriales 124 [159], el uso de este tipo de tecnologías permiten unificar una sola aplicación para múltiples dispositivos con sus respectivas especificaciones. Además, tal y como se expone en [160], el desarrollo de aplicaciones con tecnologías web reduce los tiempos de desarrollo, mantenimiento y distribución.…”

“…De hecho, en [158] se propone el uso de este tipo de tecnologías para proporcionar a broadcasters y generadores de contenido para la TV Híbrida una solución de desarrollo unificado, abstrayendo así el tipo de dispositivo para el que se va a desarrollar la aplicación híbrida. En [159], se propone una metodología para generar interfaces de usuario para aplicaciones en escenarios multipantalla y multidispositivo.…”
