How bad is
good enough: JPEG, MPEG-1, MPEG-2, MPEG-4, MPEG-7, MPEG-21 . . .
The Moving Picture Experts Group (MPEG) was formed to establish an
international standard for the coded representation of video and
associated audio.
The bit rate is reduced by exploiting the psychovisual properties of
the human visual system as well as statistical redundancies in the
image data. The MPEG-1 algorithm utilizes motion estimation/
compensation for the reduction of temporal redundancy and discrete
cosine transform (DCT) for the reduction of spatial redundancy. To
achieve additional compression on video data, variable length code (VLC)
is also used. Another characteristic of the MPEG-1 video compression
algorithm is the introduction of a bi-directional prediction method.
The MPEG-2 standard is designed for high quality use in broadcast
and telecommunications applications. MPEG-2 features CCIR 601
resolution video - similar to D-1 tape (704x480 pixels/frame, NTSC;
704x576 pixels/frame, PAL) at data rates of 3 to 15 Mbits per
second, and the concept of scalability. It also provides support for
the interlaced format, a 16:9 video aspect ratio, and multiple video
and audio channels within the same stream. In addition, MPEG-2
provides an extension ability to HDTV.

Course
Overview
This course provides a theoretical, intuitive and practical basis
for the coding of images into digital form and their compression.
Additionally, this course covers MPEG standards and alternative
proprietary compression algorithms/standards. Compression testing,
available tools and major artifacts associated with video
compression are surveyed. A review of the opportunities and
obstacles is given.
Course
Objectives
1.
Provide
background for understanding the MPEG standards
2.
Introduce
the student to both compression standards (MPEG) and proprietary
digital video formats
3.
Acquaint
the student with their (standards/formats) capabilities and
applications
4.
Compare
the MPEG-2 algorithm with other approaches to video compression
5.
Consider
opportunities and obstacles
Who Should
Attend
The course
is designed for scientists, engineers and technical managers
involved in design specification, implementation, management, or
utilization of video compression systems and others who wish to
acquire knowledge of the video compression technology field. This
course provides participants with the mathematical and conceptual
background required to understand, design, implement, and evaluate
video compression systems, in particular the MPEG-2 standard. Patent
lawyers should also find it useful.
Attendees will
benefit from the in-depth coverage of MPEG-1-2 compression standards
as well as summarized current status of MPEG-4 and MPEG-7 standards
and their relationship with other multimedia technologies and
standards. Upon completion of this course, students will be equipped
with the background that will help them understand the performance
limitations of various compression solutions.
Although video
compression is mathematically based, it is not assumed that
attendees are familiar with higher level math: modern algebra,
fractals, wavelets, etc.
