Ensemble Designs 7900 HD Up/Down/Cross Converter - Manual (Page 7)

SD Aspect Ratio Conversion
The 7900 module can perform standard definition aspect ratio conversion to convert the
aspect ratio of the SD input signal to a different aspect ratio needed on the output.
In the example shown below, the input from an SD camera with 16:9 lenses can be fed a
an anamorphic signal to the 7900 where the aspect ratio can be corrected for feeding an
SD switcher requiring an aspect ratio of Letterbox 16:9.
HD Cross Conversion
The 7900 module can perform cross conversion when an HD input signal must be convert-
ed for an output application similar to the example shown below. As shown here, the
1080i input from an HD network feed is fed to the 7900 where the format is converted to
720p as required for input to an HD router.
