Prerequisites: Operating Systems, Networks and Security
Target skills and knowledge: The course presents the main technologies for encoding, storage and dissemination of multimedia information, and analyzes distributed applications with particular reference to the Internet.
Examination methods: Oral dissemination or a project.
Assessment criteria: The exam verifies the learning of the concepts presented in the course. The student can discuss these concepts during an oral discussion, or by applying them in the design and implementation of a smartphone application.
Course unit contents: - Introduction. Multimedia and hypermedia systems. Media formats. Media and data models. Classification of media items. Audio, static images and video. Static media, continuous media, timed media.

- Images. Representation of digital images. Resolution and colordepth. Human perception of color. Models for encoding colors. Techniques for the reduction of colors. Formats standard forthe representation of images: GIF, PNG, JPEG, JPEG2000.

- Audio files. Digital representation of audio information. Sampling and quantization. Nyquist theorem. Signal-to-noise ratio. Dimension of the data vs network capabilities. Standard formats for the encoding: WAV, u-Law. MIDI systems.

- Video formats. Representation of the analog video signal. Standard NTSC and PAL. Digital video. Representation of the color. Subsampling of the color. Standard H261, H263, MPEG.

- Data compression. Reversible and non reversible compression. Entropic compressione. LZW compression. Compression of the acoustical data. Hints to the psycoacustic theory.
