The course provides the basics of modern telecommunication networks and some knowledge on the techniques needed to produce and distribute multimedia contents. Moreover, the Internet architecture is presented and the main characteristics of audio/video signals are discussed in order to motivate the opportunity and convenience of a suitable coding able to reduce information redundancy. Eventually, the principal products for multimedia streaming are shortly illustrated.
