Down Conversion
Down Conversion allows you to convert your video to a lower resolution. For example, you may need
to distribute a PAL SD version of a 1080i50 HD program master to a client. Once again, high quality
de-interlacing, down-sampling and anti-aliasing algorithms will assure outstanding down conversion
results. In this example, 1080p25 video via SDI is converted to 576i50 (PAL) with letterbox aspect ratio.
Audio is embedded in the input SDI signal.
Power your Teranex Processor and connect your inputs and outputs.
Setting your Input
Step 1. Press the IN button on the control panel and select SDI video. Teranex will display the input video
on the LCD, automatically detect the input format and illuminate the corresponding buttons.
Step 2. Select EMBED as the audio input format.
Setting your Output
Step 1. Press the OUT button on the control panel. On the Teranex 2D, all output buttons will be
illuminated blue. On the Teranex 3D, the EMBED audio button will be blue. Select the AES or
ANLG button. AES/EBU and analog audio outputs share the XLR connectors. On the Teranex
Express, the EMBED audio button will be blue.
Step 2. Press the 576 button. The button will illuminate green. Note that the I button and the 50 button
are also illuminated green. This is because interlaced video and 50 fields per second are the
only selections available for a PAL 576 output.
Step 3. Using the soft menu buttons, select Change. The output video is now displayed on the LCD
and sent to all output connectors. The buttons will also illuminate blue to confirm your settings.
Setting your Aspect Ratio
Press the LBOX/PBOX button to set your aspect ratio to letterbox. For more information on aspect ratio
conversion see pages 17 and 65-66.
Your Teranex Processor is now ready to down convert your video.
Pressing the IN button displays the input format on the
control panel buttons. In the above illustration, the input
format is 1080p25 via SDI with embedded audio.
