Familiarity
with analog and digital video would be helpful.
Although video compression is mathematically based, it is not
assumed that attendees are familiar with higher level math:
modern algebra, fractals, wavelets, etc. |

Description |
| VC-1
is in between a “rubber stamp” and a real open standard.
VC-1 is the informal name of the draft SMPTE standard describing
a video codec based on Microsoft Windows Media Video version
9. It is an evolution of the conventional DCT-based video
codec design also found in H.261, H.263, MPEG-1, MPEG-2, and
MPEG-4 Part 2 and AVC (MPEG-4 Part 10/H.264).
Microsoft® Windows Media 9 Series is a set of technologies
that enables rich digital media experiences across many types
of networks and devices. According to Microsoft, these technologies
are widely used in the industry for media delivery over the
internet and other media, and are also applied to broadcast,
high definition (HD) DVDs, and digital projection in theaters.
At the core of these technologies is a state-of-the-art video
codec called Windows Media Video 9 (WMV-9), which provides
competitive video quality for reasonable computational complexity.
WMV-9 has been submitted to and is currently being considered
for standardization by the Society of Motion Picture and Television
Engineers (SMPTE).

Objectives |
At the
end of this course, students will be able to accomplish the
following:
1. Understand the advantages of using digital image and video
compression algorithms in various digital imaging related products.
2. Have a clear picture of the engineering of a compression
system.
3. Compare the MPEG-2 algorithm with other approaches to video
compression.
4. Study the technical details of the MPEG and MPEG-like algorithms.
5. Understand requirements for: broadcast/DTV, streaming, and
downloading.
6. Make competent decisions regarding opportunities to incorporate
technical advances into the product.
7. Understand the performance limitations of various compression
solutions.
8. 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. The material should also be of keen interest
to scientists, engineers and managers working in the following
roles: strategic planners, business development and marketing
professionals, value-added developers and integrators, content
owners/providers, etc.
