    Mestrado em Engenharia Eletrónica e TelecomunicaçõesThe breadth of availability and variety of online video contents has helped to encourage a far more mobile experience, which has proved particularly popular among younger generations. Over The Top (OTT) services, particularly those on-demand video platforms, became more and more attractive to consumers when compared with the current main TV packages. This document describes how the video OTT Ecosystem works from a technical side. The description presented reaches both ends of the distribution chain: from how the video signals are acquired and processed, thru all the way to how they are delivered to the client, passing by the challenges and consequences that such services have on the network. The main objective of this dissertation is to understand the possibility to create in Portugal a new operator where the core business is video delivery using only OTT services.A amplitude e variedade de conteúdos disponíveis online têm ajudado a promover uma experiência cada ver mais móvel da televisão, serviço que se tem revelado particularmente popular entre os mais jovens.

    Monetizing IMS-based IPTV through personalized advertising

    The adoption of the IP Multimedia Subsystem (IMS) has faced a number of challenges. Furthermore, countries with developing infrastructure face additional difficulties. It is important for such countries to overcome these obstacles in order to adopt Next Generation Network (NGN) architectures and compete globally with operators offering IMS services. Funding the deployment of NGNs is a major hurdle for developing countries. Investors need a guarantee of returns within a particular timeframe. However, the declining Average Revenue Per User (ARPU) and the lack of a killer application for the IMS inhibit this. To overcome these challenges, this paper proposes a personalized advertising system for IMS-based IPTV to generate revenue based on marketing and incentivize IMS roll out for telcos. Furthermore, the system is integrated with the IMS charging framework to reward users for viewing advertisements
