KISA KURSLAR:
MPEG Standards: including MPEG-4 and MPEG-7
Prof. Murat Tekalp
University of Rochester
Early MPEG standards, MPEG-1 and MPEG-2, have impacted consumer electronics
and broadcast industries with the introduction of VideoCD, DVD video, and
most recently digital TV and HDTV. The course starts with an in-depth review
of the MPEG-1 and MPEG-2 technologies, and then moves onto the more recent
MPEG-4 and MPEG-7 (just underway) standards being developed by the same group.
MPEG-4 is an international standard that provides core technologies for
efficient object-based compression of multimedia content for transmission,
storage, and manipulation. MPEG-7 addresses content description technologies
for efficient and effective multimedia retrieval and browsing. Both are
essential in developing interactive digital multimedia broadcast and
internet multimedia applications. The course covers the MPEG-4 visual part,
including object-based natural video coding, shape coding, error-resilience,
face animation coding, 2D/3D geometry coding and still texture coding.
We also discuss VRML and MPEG-4 systems technologies including scene
description, update, animation, elementary stream management, and
transport/network interfaces. Next, the goals of MPEG-7 are presented and
the related technologies, including features, descriptors, description
schemes, and description definition language are reviewed. Finally,
the current status of MPEG-4 and MPEG-7 standards and their relationship
with other multimedia technologies and standards will be summarized.
