At IBC2007,
engineers from Harris Corporation (NYSE:HRS), an international
communications and information technology company, will present
two key technology papers that address broadcasters’
concerns as they move to high-definition (HD) transmission.
The presentations,
taking place at the RAI conference and exhibition centre in
Amsterdam, Netherlands, will address the following:

– Use of Automated, File-Based Quality Control Tools
in a Broadcast Environment, by Dave Guerrero, Vice President
and General Manager, Videotek® Test and Measurement, Harris
Broadcast Communications Division
This paper highlights the technology that
engineers and technicians should employ in order to assess
the quality of compressed, file-based audio and video content
to enable maximum customer satisfaction.
The transition to file-based media assets
at content playout facilities has proved daunting for Quality
Control (QC) departments as they are faced with checking an
ever-growing amount of compressed digital content. Poor video
and audio quality are not acceptable in today’s competitive
market where advertising revenues and customer satisfaction,
as well as loyalty to the brand, are of paramount importance.
QC has historically been performed by in-house staff who monitor
programme content in real time and write reports on the errors
they observe. Rejected programmes are returned to content
suppliers for necessary repair and re-evaluation prior to
transmission. This represents a very time consuming and costly
process for broadcasters.
Thoughtful use of technology is making it possible to not
only evaluate erred content, but also to conveniently perform
the necessary repairs while remaining in the compressed format.

— Algorithms and Artifacts: A Practical Guide to Deinterlacing,
by Leigh Whitcomb, Principal Engineer
This paper examines the challenges of deinterlacing
and the algorithms used therein. The algorithms examined include
field-based, fixed blending, diagonal interpolation, motion
adaptive, motion compensated and film mode. Some guidelines
for the means by which to create content to reduce deinterlacing
artifacts are also discussed.
Deinterlacing is an important component
of high-quality image conversion. However, it is a very complex
process, and no algorithm is perfect. Every algorithm introduces
artifacts that vary with image content. Today’s broadcasters
have new challenges, as more artifacts are being generated
in which film, video, graphics and overlays are increasingly
being combined.
To select the best deinterlacer for an application,
it is important to understand the tradeoffs and the types
of artifacts that may be introduced based on the image content
and the deinterlacing algorithm selected. This paper sets
out to address these challenges.
