Subject fundamentals
The course is taught in Italian.
The expected knowledge outcome of the course covers:
* the most important algorithms for digital voice, audio, image and video processing;
* the protocols and network architectures for real-time data transmission;
* the most important multimedia applications, including theirs architectures and constraints;
* the techniques to control the quality of service of the most common multimedia applications over IP networks.
Moreover, the presentation of the topics is oriented to allow the student to acquire the basic abilities to evaluate systems in the previous fields and perform correct design choices in those contexts.
Expected learning outcomes
* Knowledge of the most common techniques for digital voice, audio, images and video signal representation.
* Knowledge of the most common techniques for robust transmission of digital signals transmitted over packet networks.
* 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, by performing the most appropriate design choices in each considered case.
* 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 resilient transmission techniques for the various application scenarios.
Prerequisites / Assumed knowledge
Basic knowledge of digital signal processing theory: digital filters, Fourier transform, time- and frequency-domain signal analysis. Basic knowledge of computer networks protocols and architectures. Knowledge of programming techniques. For laboratory activities, basic computer usage abilities are required.
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
The course is characterized by a strong theoretical approach. The course also includes two laboratory activities that will guide the students in the understanding of some concepts presented during the lectures about coding and transmission of multimedia data.
Texts, readings, handouts and other learning resources
The electronic version of all 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 available through the Politecnico course website.

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 in case of doubts, 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 exam aims to assess the student in terms of the expected knowledge and the abilities that he/she should acquire. The exam is composed of short exercises and multiple choices questions that cover all the main topics of the course. The final mark is computed on the basis of the written test mark and the oral mark (if required).
