The course aims to provide systematic and modeling aspects related to the support of multimedia services in telecommunications networks. We will define the characteristics of the media and the different sources (human visual system, auditory system, etc..). Will cover aspects related to architectural and protocol models and in particular will be considered source coding, secure information channel coding, and integration of different information media (video, audio, data, reality 'virtual). Part of the course is devoted to innovative coding and transmission.
