[null,null,null,"Sommario/riassunto","Un demi-siècle après la vague des indépendances de 1960, l’année 2010 a marqué, pour de nombreux pays d’Afrique, le cinquantenaire de leur accession à la souveraineté et a été jalonné de multiples célébrations. Cet ouvrage se propose de faire revivre ce moment clé des indépendances, à travers une série d’analyses témoignant du moment de l’indépendance, de la diversité des réactions qu’il a générées et du souvenir que les Africains ont construit ou conservé de ces journées de fête – ou de doute – jusqu’au jubilé de 2010. À partir d’un questionnement renouvelé, les contributions mettent à jour l’extrême diversité des perceptions et des vécus qui coexistent et la complexité jamais démentie du rapport entretenu à cet événement fondateur. Colère et joie se sont mêlées à Tananarive et au Cameroun, fierté et déception ont été perceptibles à Lomé et Dakar. Des fêtes officielles parfois convenues aux bals où l’on a dansé « jusqu’à fatigué », les sociétés africaines ont tenté de s’approprier le moment « indépendance » en faisant parfois entendre des voix discordantes, notamment celles des « vaincus » des luttes politiques de la décolonisation (radicaux ou modérés) ou celles plus discrètes des mondes populaires ruraux et urbains, à la recherche d’une émancipation réelle et non formelle."]

[null,null,null,"Sommario/riassunto","This volume presents a parametric packet-based audiovisual quality model for Internet Protocol TeleVision (IPTV) services. The model is composed of three quality modules for the respective audio, video and audiovisual components. The audio and video quality modules take as input a parametric description of the audiovisual processing path, and deliver an estimate of the audio and video quality. These outputs are sent to the audiovisual quality module which provides an estimate of the audiovisual quality. Estimates of perceived quality are typically used both in the network planning phase and as part of the quality monitoring. The same audio quality model is used for both these phases, while two variants of the video quality model have been developed for addressing the two application scenarios. The addressed packetization scheme is MPEG2 Transport Stream over Real-time Transport Protocol over Internet Protocol. In the case of quality monitoring, that is the case for which the network is already set-up, "]
[{"$nulls":4},"the audiovisual stream is encrypted either at the level of Packetized Elementary Stream or of the Transport Stream. The presented model became standardized under the ITU-T P.1201 and P.1201.2 recommendations."]
