Multimedia Architectures
A.Y. 2024/2025
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.

Assessment methods and Criteria
Methods of verification are:
1. Written test (max grade 30/30)
2. Oral test, Thematic Deepening, Project (optional) that will result in an increase or decrease in the grade of the written test by + or - 3 points
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
