| DESCRIPTION | The study-unit first overviews Multimedia Information - Audio, Video, Graphic, and Textual - and the Quality of Service (QoS) and Quality of Experience (QoE) targets required for acceptable delivery over Multimedia networks. Multimedia Networks including Terrestrial - fixed, wireless and mobile; and Satellite are then introduced and their characteristics studied with a view to understand their multimedia delivery capabilities. The distribution of multimedia content over TCP/IP with QoS guarantees will be studied using RTP/UDP/IP and Reservation Protocols. Current Multimedia Systems such as Satellite Broadcasting, Digital Terrestrial Broadcasting, Digital Mobile Systems, and OTT systems will be covered in some depth. The study-unit will then focus on audio (both speech and music) representation and coding. The transmission of digital audio will be studied as a real-time service posing stringent latency QoS requirements on multimedia networks. SIP and H323 VoIP protocols will be studied and analyzed. Their use in supporting Unified communications will also be studied. Finally the role of the IMS in next generation multimedia networks will be introduced. Study-unit Aims: CCE5401 first reviews the multimedia information that is transacted over telecommunications networks, and studies the requirements for the various components. Then, generic properties of multimedia networks are introduced, followed by a description of current networks and how these support multimedia transmission. The study-unit also overviews the work on future multimedia systems such as Multimedia transmission over IPv6, HDTV, 3D TV and multimedia in 4G mobile networks. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Understand the nature of the various multimedia information sources and the QoS demands each component places on the network; - Understand the types of broadcasting channels available, modes of transport and the protocols that support multimedia transmission, rather than just best-effort traffic; - Understand how the major current telecommunications networks support multimedia transmission, including terrestrial, satellite, fixed, mobile and those based on IPv6; - Understand how new multimedia techniques shall stress telecommunications networks and how the latter are expected to evolve to meet the challenges; - Understand how RTP/UDP/IP and reservation protocols are used to transport multimedia traffic with QoS guarantees in TCP/IP networks; - Understand how audio signals are digitized, compressed and transmitted in current and future multimedia networks; - Understand the role of SIP and H323 protocols in delivery of multimedia services in TCP/IP networks; - Understand Unified Communications services and systems; - Understand the role of the IMS in next generation multimedia networks; 2. Skills: By the end of the study-unit the student will be able to: - Characterise and describe the properties of multimedia information sources; - Characterise and describe the characteristics of current and future multimedia networks; - Predict, characterise and measure the interaction between multimedia and current and future multimedia networks; - Describe Audio representation and coding techniques in detail; - Design real time multimedia network using SIP protocols; - Describe the role of UC and IMS in defining current and future multimedia communications networks.
