Abstract
Still today, diagnosing a problem with multimedia
resources,
such as video and sound cards, is insufficiently
automated.
These resources therefore cannot be accurately managed.
One
reason for this is the lack of their thorough modeling.
In
this paper, we fulfill this need, by proposing a generic
information model, which we further apply to an MPEG2
video
codec. We highlight the main characteristics of this
kind
of codec, identify parameters that influence these
characteristics, and reveal some of the trade-offs that
the
application developer can consider in order to design
efficient
software for MPEG2 codecs. In addition to the benefits
of
this modeling for the user and the application
developer, we
also show how useful it could be for the providers of
distribution
services, such as "live" video transmission. These
providers
can use our model to achieve resource management on an
end-to-end
basis.
Keywords: Multimedia resources, information model, MPEG 2, video codec.
