Objectives

This course aims to introduce the fundamental concepts of digital audio and video, compressed digital technologies used in television, TV diffusion and distribution networks, technologies of TV production, concepts of interactive TV and 3DTV.

Learning outcomes and competences

At the end of the course students will be able to:

-understand the basics in the digital representation and compression of audio and video signals used in television;

-identify the components of a television distribution system, the features offered by each, as well as various implementation alternatives;

-know the different alternatives for implementing a digital television distribution service (via broadcast, cable, satellite, IPTV, OTA, fixed versus mobile broadcast);

-be able to identify the characteristics that components of the television service should have to satisfy identified requirements (to select formats; type and degree of compression to be used; type of additional information needed; transmission infrastructure; transmission parameters; protocols).

-be familiar with the various international standards that are used in television and digital cinema, from media compression and metadata, through formatting to modulations, ciphers and protocols.

Teaching methods and learning activities

Classes will be based on the presentation and demonstration of technology. Laboratory classes will be based on practical assignments, so that students can apply and deepen their knowledge. The laboratory assignments consist mainly in the development of programs in MatLab or C language for image processing, audio and video. In particular, programs that implement operations on the audiovisual signals that typically exist in digital TV systems, such as quantization, spatial transform, motion compensation or entropy encoding.

Eligibility for exams

Students have to reach a minimum mark of 40% in the assignments and attend to classes, to be admitted to exams. Students have to reach a minimum mark of 30% in the exam, to complete the course.

Calculation formula of final grade

(9,5/20) * average mark of the assignments+ (10.5/20) * Exam

Special assessment (TE, DA, ...)

Students have to do two laboratory assignments identical to the ones done by ordinary students.
