On the other hand, what HDNet has done is to go back to the original
film masters of the "Hogan's Heroes" series and performed a true "HD
transfer" of those film frames to 1080i HD.
At the risk of oversimplifying the process, HDNet has "re-scanned" the
film master in order to capture more of the resolution that existed in
the original film frames of the series but that was lost when the film
was converted to 480-line NTSC video. At the same time, HDNet has
exposed more of the original film frame in order to fill (or nearly
fill) the 16x9 aspect ratio mandated in the HD standard.
