Subject fundamentals
The course is taught in Italian.

The main course topics are:
* the most important algorithms for digital voice, audio, image and video processing;
* the protocols and network architectures for real-time data trasmission;
* the most important multimedia applications: architectures and constraints;
* techniques to control the quality of service of the most common multimedia applications over IP networks.
Three subsequent courses will give, to the interested students, more in-depth presentations of the techniques for processing and transmission of voice-audio and video, as well as investigation of application development from a more practical point ov view.
Expected learning outcomes
* Knowledge of the most common techniques for digital voice, audio, images and video signal representation.
* Ability to evaluate the pros and cons of the main multimedia coding techniques, giving the student the ability to choose the most suitable techniques for the various application scenarios.
* Ability to face the most important issues related to the use of various multimedia formats.
* Ability to autonomously investigate, if desired or necessary, how specific multimedia coding techniques work.
* Ability to choose the most suitable protocols and architectures for the various application scenarios.
* Ability to choose the most suitable error resiliency techniques for the various application scenarios.
Prerequisites / Assumed knowledge

Basic knowledge of digital signal processing theory: digital filters, Fourier tranform, time- and frequency-domain signal analysis. Basic knowledge of computer networks protocols and architectures. Knowledge of programming techniques.
Contents
* Introduction about multimedia signals, coding and compression (4)
* Digital representation of audio, voice, images and video (22)
* Protocols and architectures for real-time data transmission (10)
* The most important multimedia applications: constraints and architectures (10)
* Techniques for QoS and error control for the most important multimedia applications over IP networks (14)
Delivery modes

A few laboratories will explain the concepts presented during the course that is, however, characterized by a strong theoretical approach. More in depth laboratories are offered in other subsequent courses.
Texts, readings, handouts and other learning resources
The electronic version of the slides and notes presented in the course by the teachers will be made available to all students. Examples of the exam past written tests will be available as well. All the teaching material will be made availble through the Politecnico course website. An updated list of reference books and sources will be presented by the course teacher during the lectures. The resources will also be available through the Politecnico course website (in conjunction with the library services).
Assessment and grading criteria

The final exam is a written test. If the mark is at least pass, the student can choose to give an oral examination, which could only moderately improve the mark in the written test or, at teacher discretion, the student can be asked to attend an oral exam. The written exam must be solved within two hours, without using any aid or source of information other than his/her personal memory. The final mark is computed on the basis of the written test mark, the mark for laboratory projects (if present) and the oral mark (if required).
