SD Aspect Ratio Conversion

The BrightEye 90-FA can perform standard definition aspect ratio conversion to convert
the aspect ratio of the SD input signal to a different aspect ratio. In the example below,
the input from an SD camera with 16:9 lenses can feed an anamorphic signal to the
BrightEye 90-FA where the aspect ratio can be corrected for input to an SD switcher that
requires 16:9 Letterbox.

HD Cross Conversion

The BrightEye 90-FA can perform cross conversion between two different types of HD
signals. As shown here, the 1080i input from an HD network feed is sent to the BrightEye
90-FA where the format is converted to 720p as required for input to an HD router.
