SUMMARY:Cooperation between LTE and emergent DVB technologies for an
 efficient delivery of mobile TV
DESCRIPTION:The broadcast/cellular cooperation for a common delivery of
 Mobile TV is at the heart of the emerging mobile broadcast technologies\,
 namely the mobile extension of the second generation digital video
 broadcasting for terrestrial reception (DVB-T2Lite) and its follower
 DVB-Next Generation Handheld (DVB-NGH). These broadcasttechnologies aim to
 cooperate with the Long Term Evolution (LTE)\, as the latter is intended to
 be the bearer of Mobile TV thanks to its enhanced-Multimedia Broadcastand
 Multicast Service feature (e-MBMS).Even though the 3GPP/DVB cooperation is
 not a new topic and was investigate dwith the introduction of the previous
 DVB technology\, known as DVB-Handheld(DVB-H)\, most of the works
 addressing this issue considered a common service area covered by both DVB
 and cellular systems and focused solely on the impact of such cooperation
 in terms of capacity gains brought by 3GPP and error repair gains brought
 by DVB. This strategy was judged to be expensive since a new and very dense
 DVB network was needed. In order to overcome this problem and decrease as
 much as possible the need for a new broadcast network\, we propose in this
 thesis a hybrid DVB/LTEnetwork with a coverage extension strategy\, where
 the LTE system\, planned for almost a universal coverage\, is used to
 deliver Mobile TV in areas not covered by recent DVB-T2 Lite (or eventually
 DVB-NGH) network. In this context\, we explore twomain issues:1. Mobile TV
 services have to share LTE resources with other higher priority services
 such as voice traffic. The dynamicity of the latter will impact the Quality
 of Service (QoS) of Mobile TV. We propose a new QoS-based planning1for the
 hybrid DVB/LTE so as to guarantee an acceptable watching experience without
 over-dimensioning the LTE system. We derive using Markov chain analysis and
 hitting time theory\, several QoS metrics pertaining to mobile TV
 performance\, such as interruption frequency and duration.2. A new business
 model which clarifies the relationships between the different factors of
 the ecosystem namely DVB and LTE operators as well as the TVchannel
 providers and constructs the service area from an economic point of view is
 needed. In fact\, the absence of a clear and viable economic model that
 resolves the monetary conflicts between cellular and broadcast operators
 was one of the main drawbacks behind the failure of the first attempt of
 mobile TVd elivery by cooperating UMTS/DVB-H. We develop in this thesis a
 profit sharing strategy for the cooperative network\, using coalition game
 concept Shapley value and Nash equilibrium for a self-enforcing strategy.
 We further develop anew framework using real option theory coupled with
 coalition games for investment decision in mobile TV networks (whether an
 operator should enter the mobile TV market and\, if yes\, when to do so)
 and show how operators canin corporate the uncertainties related to demand
 and network operation costs.We propose a bi-level dynamic programming
 algorithm to solve numerically the developed real option game.
