\section{The Product: Digital Video Recorder}

A Digital Video Recorder (DVR) is described in the same perspective as the building WDC
to compare building architecting and electronic product architecting.
One of the main functions of a DVR is {\it time shifting}, providing a consumer freedom in time.
Figure~\ref{fig:ETexampleTimeShifting} shows a simple example of the application
of {\it time shifting}.

Some objectives of the consumer are summed up in table~\ref{tab:WDCobjectivesConsumer}.

The product requirements are translated in a design in an iterative fashion.
Figure~\ref{fig:WDCarchitectingTechnicalProduct} shows some of the relevant technical
side of a DVR.

Finally all these issues are mapped on the ''CAFCR''-model,
see figure~\ref{fig:WDCannotatedCAFCRproduct}
Many similarities of the WDC and the DVR ''CAFCR''-model are evident.
