Multimedia Architectures
A.Y. 2021/2022
Learning objectives
The course aims at presenting digital models and systems for the processing, coding, storage, retrieval and distribution of multimedia information (texts, images, audio, video). The course deals with issues about the analysis, design and synchronization of complex multimedia applications as well as research and development activities in this field will be discussed.
Expected learning outcomes
The students will acquire the necessary knowledge for managing multimedia information and developing related architectures for the storage and communication of images, audio and video. In addition, students will develop high-level analytical and operational skills for the development of complex multi-disciplinary applications.
Lesson period: Second semester
Assessment methods: Esame
Assessment result: voto verbalizzato in trentesimi

Lesson period
Second semester
The next semester the course will be held in the presence by means of lectures with the help of slide projections, videos and other multimedia material.
For students unable to participate in face-to-face lessons due to the COVID emergency, lessons in live streaming will be offered. Lessons will not record for further downloads.
In the event of new emergencies and subsequent lockdowns, the measures adopted last year will be applied.
As for the lessons, the exams will also be held face to face in computerized classrooms. In cases of students unable, for valid reasons, to participate in face-to-face exams, tests will be provided remotely.

Assessment methods and Criteria
Methods of verification are:
1. Written test
2. Oral test, Thematic Deepening, Project (optional)
The evaluation criteria of the written test concern:
- Knowledge of the content
- Adherence of the response to the track
- Ability to make connections
- The relevance of the contents in relation to the question
The evaluation criteria of the oral test/thematic deepening/project concern:
- the focus of the issue
- logical rigour and use of technical language
- fairness and clarity of exposure
- The critical awareness, personal interpretation skills, richness and relevance of the oral presentation
