A study of underpinning requirements, technologies, standards, industry developments, trends and network architectures in the delivery of multimedia (including audio and video) telecommunications services.
This is structured in three phases:
- Human perception of multimedia (vision and hearing), which establishes a set of fundamental requirements for signal structure, sampling and fidelity
- Technologies common to the representation and delivery of multimedia are introduced, including media formats, data compression, data description, copyright protection, streaming, content delivery networks and error recovery
- The major categories of multimedia service (Internet streaming, broadcast television, videoconferencing, Video-on-demand, etc.) are analysed, recognising the role of the above technologies in these systems and introducing additional components necessary to satisfy customers or users of the services
- Introduction to multimedia services and their requirements;
- Audio, video and image compression technologies for transmission and storage;
- Multiplexing and packaging techniques;
- Error detection, protection, recovery and concealment;
- Media streaming solutions;
- Media servers and storage techniques;
- Content delivery networks;
- Technical methods for protection of copyright and content distribution rights;
- Workflow in multimedia production and publishing systems;
- Key multimedia services and their delivery solutions (Internet streaming, IPTV, video-on-demand, digital TV and video calling);
- Emerging technologies in multimedia distribution and content delivery.
Intended learning outcomes
INTENDED LEARNING OUTCOMES (ILOs)
Having completed this subject it is expected that the student be able to:
- Understand the principles of human audio and visual perception and how it impacts on electronic reproduction
- Understand the working principles of relevant data compression methods, multimedia containers and multiplexing, content delivery systems, intellectual property rights protection, multimedia servers and storage, metadata and back-end systems necessary to deliver multimedia
- Understand the requirements and technical solutions which satisfy them, for the delivery of major classes of multimedia services (Video-on-demand, IPTV, Video calling, Internet streaming, etc.)
- Understand the technical literature associated with this subject, carry out their own literature-based research project, synthesise their own view, report on the topic and communicate it effectively
On completion of this subject, the students should have developed the following generic skills:
- An advanced understanding of how a knowledge base evolves;
- An ability to identify weaknesses and risks in technical solutions;
- Analytical, critical and creative thinking, with an aptitude for continued self-directed learning;
- A sense of intellectual curiosity;
- An ability to interpret data and research results;
- An ability to learn in a range of ways, including through information and communication technologies;
- An ability to evaluate and synthesise the research and professional literature;
- A capacity to manage competing demands on time, including self-directed project work.
