The downconverter in the Production Afterburner changes the 16:9 aspect ratio of the input HDTV signal
to the 4:3 aspect ratio of the output SDTV in one of three ways. Letterbox mode reduces the overall
picture proportionally so that the complete width fits in the width of the 4:3 raster. This produces a black

from the center of the picture while maintaining the full height of the picture. This loses picture information
at the extreme left and right sides of the picture.
