Abstract
[EN] The combination of broadcast and broadband
(hybrid) technologies for delivering TV related
media contents can bring fascinating opportunities. It is
motivated by the large amount and diversity of media contents,
together with the ubiquity and multiple connectivity capabilities
of modern consumption devices. This paper presents an
end-to-end platform for the preparation, delivery, and synchronized
consumption of related hybrid (broadcast/broadband)
media contents on a single device and/or on multiple close-by
devices (i.e., a multi-device scenario). It is compatible with the
latest version of the Hybrid Broadcast Broadband TV (HbbTV)
standard (version 2.0.1). Additionally, it provides adaptive and
efficient solutions for key issues not specified in that standard,
but that are necessary to successfully deploy hybrid and multidevice
media services. Moreover, apart from MPEG-DASH and
HTML5, which are the broadband technologies adopted by
HbbTV, the platform also provides support for using HTTP Live
Streaming and Real-time Transport Protocol and its companion
RTP Control Protocol broadband technologies. The presented
platform can provide support for many hybrid media services.
In this paper, in order to evaluate it, the use case of multi-device
and multi-view TV service has been selected. The results of both
objective and subjective assessments have been very satisfactory,
in terms of performance (stability, smooth playout, delays,
and sync accuracy), usability of the platform, usefulness of
its functionalities, and the awaken interest in these kinds of
platforms.This work was supported in part by the "Fondo Europeo de Desarrollo Regional" and in part by the Spanish Ministry of Economy and Competitiveness through R&D&I Support Program under Grant TEC2013-45492-R.Boronat, F.; Marfil-Reguero, D.; Montagud, M.; Pastor Castillo, FJ.
