Aspect Ratio Selection
Aspect ratio conversion (ARC) provided in the Teranex Processor includes fixed modes such as Anamorphic
(
ANAM
),
14x9
, Letterbox/Pillarbox (
LBOX/PBOX
), Center Cut/Zoom (
CCUT/ZOOM
) and
SMART
conversion. The output aspect ratio conversion you use is dictated by your desired output format. HD to
HD conversions are always 16:9, therefore the Aspect Ratio selection buttons do not apply and will not be
lighted, 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.
