TUTORIAL II
Multimedia System Design - Providing Quality Services
Rajeev Kumar
Indian Institute of Technology, Kharagpur

Audience: The tutorial is intended for practicing engineers in the area of Multimedia Technology. It is also very informative for engineering students with interests in multimedia codecs, transcodes, servers and communication. Prior exposure to algorithms, and fundamentals of operating systems and networking is a plus though not essential.

Course Description: Advances in multimedia technology coupled with explosive growth of Internet and the availability of high computing resources at affordable cost have led to the wide-spread use and exchange of multimedia data-streams over the Internet for varied applications. Side-by-side, the emergence of widely varying network capabilities in accessing multimedia objects for presentation through a variety of client devices with different resource constraints constantly poses new challenges to multimedia technology. In such an environment of varying network, storage, and display capabilities, there is a need to customize multimedia objects for the prevailing operating conditions for optimizing the resource-usages on one hand, and providing differentiated quality services to the application/user.

This interdisciplinary tutorial provides – (i) an introduction to basic concepts and techniques of multimedia computing, (ii) an in-sight into core technologies of system design and internals of multimedia system, (iii) an understanding of data-semantics for perceptual appreciation of time-constrained multimedia data, and (iv) a familiarity with the future extensions.

Key design considerations to developing multimedia systems will be looked into and followed with a few case-studies specific to some applications. In general, the tutorial is aimed at quickly laying a foundation that can be used as the basis for further study, research and system-development in wide ranging multimedia techniques and needs for various applications.
