Note: Active Format Descriptor (AFD) - normally it is necessary to set both the TV
Aspect Ratio and Conversion to correctly display the video program on the TV
system. The Auto AFD option enables the transcoder output to automatically match
the display format of the video program to the TV system based on specific (uplink)
program information carried in the transport stream. In this case, the transcoder
performs the conversion based on the TV Aspect Ratio setting combined with the
program-specific uplink information to provide the "best fit" for display of the
program material on the TV. This feature is primarily used in 16:9 and 14:9 (wide
screen) applications.
