release. The output aspect ratio conversion you use is dictated by your desired output format. HD
to HD conversions are always Anamorphic, while SD to HD and HD to SD conversions may use any

aspect ratio conversion, depending on your needs for the output video aspect ratio. The sections

below provide details of the aspect ratio conversions available.
The Teranex Processor is an "output centric" processor. This means that you may establish parameters
for your chosen output video format that will automatically be maintained regardless of the input
format received. For example, if you decide that your output will be 1080i59.94 (16:9), you can set the
output ARC to Anamorphic and all input signals will formatted for the widescreen, 16:9 output. This
may be OK if your input format is also 16:9. But what happens if your source is a standard definition 4:3
aspect ratio? In that case, the Anamorphic stretch would be applied, which may not be desirable. To
prevent the geometric distortion caused by the Anamorphic stretch, you may set your OUTPUT aspect
to LBOX/PBOX mode, which will automatically put the 4:3 image inside a 16:9 pillarbox output! (See
illustration below.) Since the Processor defaults to the anamorphic mode for all HD to HD conversions,

any HD input will retain its proper 16:9 aspect ratio, even with the chosen LBOX/PBOX setting.

Similarly, if your OUTPUT is a standard definition 4:3 format and your input is sometimes a 16:9 HD
source, you can set the output aspect ratio to LBOX/PBOX to achieve a letterboxed 16:9 display
inserted into your 4:3 output.
