The FP7 M EDIEVAL project, which started in 2010, has been defining the necessary evolutions over today's mobile Internet architecture, in order to more efficiently support the upcoming growth of video services, in mobile wireless environments. This paper evolves from these initial definitions, by taking into consideration the requirements placed by a core set of next generation video services and defining a global architecture. We describe its main functionalities and subsystems as well as the necessary interfaces, towards the operation of these services in different use cases.
