Agradecimientos
Me gustar´ıa dar las gracias a mi tutor, Daniel D´ıaz S´anchez, por toda la paciencia que ha tenido conmigo y por atenderme cuando me presentaba en su despacho sin previo aviso. Adem´as, ser´ıa injusto no darle las gracias a Davide Proserpio por su ayuda y dedicaci´on en aquellas cuestiones relacionadas con el servidor.
Finalmente, debo agradecer a Jean-Baptiste Kempf, a Pierre Ynard y a Geoffroy Couprie, cuyos alias respectivamente son j-b, linkfanel y geal. Por su ayuda a trav´es del foro de videolan y del canal de IRC #videolan, en los temas de migraci´on del programa VLC a la plataforma Windows CE.
Resumen
Las redes de pr´oxima generaci´on, o NGN, es la tecnolog´ıa que relevar´a al actual sistema de tercera generaci´on, 3G. Estas redes est´an basadas en tecnolog´ıa IP y proporcionan servicios de datos, telefon´ıa y multimedia. El principal objetivo es mezclar la tecnolog´ıa IP con los dispositivos m´oviles. Desde el punto de vista de los operadores, las redes NGN permiten la integraci´on en la red de servicios desarrollados por terceras personas. Y adem´as el proceso de desarrollo de un nuevo servicio es m´as r´apido y barato. Desde el punto de vista del usuario, ofrece un amplio rango de servicios que podr´an ser utilizados desde cualquier dispositivo con acceso a Internet. Este dispositivo puede ser un tel´efono m´ovil, el ordenador de la oficina o el ordenador de su casa.
El objetivo de este documento es describir el estudio de un sistema de televisi´on m´ovil basado en redes de pr´oxima generaci´on. El documento ex-pone un estado del arte sobre las tecnolog´ıas relacionadas con este proyecto y el proceso de desarrollo del proyecto. Finalmente, se presentar´an los resulta-dos del estudio y desarrollo del proyecto y se propondr´an unas futuras l´ıneas de desarrollo.
Abstract
Next Generation Networking, or NGN, is the technology that will replace the current third generation system, 3G. These networks are based on IP technology and provide data, voice and multimedia services. The aim is the merge of IP technology and the mobile devices. From the operators point of view, NGN allows to integrate in the network services developed by third parties. And also, the development process of a new service is faster and cheaper. From the users point of view, it allows a wide range of services that will be used from any device with access to Internet. This device could be a mobile phone, an office computer or a personal computer.
The aim of this document is to describe the study of a mobile television system based on Next Generation Networking. The document presents the state-of-the-art about the technologies related with this project and the de-velopment process of it. Finally, the results of the study and dede-velopment of the project are explained, and the future ways of development will be proposed.
