Objectives

This course focuses on the basic principles and development of TV systems, together with the services and functionalities these systems offer nowadays, whilst also offering an analysis of advanced formats, applications, related technology and standards. It offers a broad view of the analog to digital switchover process and of the significant changes since the switch-off in the public television service. It briefly reviews the concepts of audiovisual digital signals representation and digital technologies. It studies the technologies and standards currently in use for multiplexing and transporting the television signals and to create the service offered to viewers. It details all the technological aspects of the digital terrestrial broadcasting system and those related to IP distribution of TV signals and applications. It analyses emergent technologies and standards to build advanced TV applications. It studies the processes for the generation, compression and presentation of stereoscopic and multiview signals.

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 (terrestrial broadcasting, cable, satellite, IPTV, OTA, fixed versus mobile broadcasting);

-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.

- be able to identify the emergent technologies and standards that can be used to create advanced television services, namely bridging the more traditional broadcasting world with the IP networks.

- to understand the processes of generating stereoscopic signals and presenting them to the viewer.

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 audio and video manipulation and systems aspects of the TV service. A review work will also be proposed analysing essential aspects of a modern TV service. Each group of two students should select and propose atopic within the digital TV context. It can be a study market / state-of-the-art identifying: existing technology, protocols and development tools: requirements, challenges, added-value and opportunities; challenges to overcome and possible solutions; etc. It can also be a software project using open source tools and/or Matlab.
