requiring video technology. Again, the need is to understand
basic concepts and applications, without being overwhelmed by
the details and implementation complexity.
The market sizes of these new video applications are growing
rapidly. For example, here are some publically available
projections:
• ABI Research believes that the video surveillance market is
poised for explosive growth, which the firm forecasts to
expand from revenue of about $13.5 B in 2006 to a remarkable
$46 B in 2013. Those figures include cameras, computers and
storage, professional services, and hardware infrastructure:
everything that goes into an end-to-end security system.
• According to Wainhouse Research, the overall endpoint
market for video conferencing will grow from $1.3 B in 2007
to over $4.9 B in 2013. Videoconferencing infrastructure
product revenues, including MCUs, gateways, and gate-
keepers, are forecast to grow to $725 M over the same period.
• HD penetration rates: there is still a lot of work to be done to
develop, store, edit and transmit HD signals within both the
USA and Europe.
Digital cinema is ramping upwithin the next five years

US theaters are to be upgraded in 2010
2011. Digital cinemas
drive significant design activity in HD and 4K video processing.
The $16 B US medical-imaging product industry will grow six
percent annually in the course of 2010 based on technological
advances, aging demographics and changing health care
approaches. Equipment will outpace consumables, led by CT
scanners and by MRI and PET machines.
All of these trends and many more lead us to believe that there
is a tremendous and growing demand for a topic that demystifies
video processing. Professional engineers, marketers, executives
and students alike need to understand:
• What is video - in terms of colors, bits and resolutions?
• What are the typical ways that video is transported?
• What functions are typical in video processing - scaling, dein-
terlacing, mixing?
• What are the typical challenges involved in building video-
processing designs - frame buffering, line buffering, memory
bandwidth, embedded control, etc.?
• What is video compression?
• How is video modulated, encoded and transmitted?
These concepts provide a solid theoretical foundation upon
which the reader can build their video knowledge. This topic
intends to be the first text on this subject for these engineers/
students.
