Cross Conversion
Cross Conversion allows you to change the video resolution and/or aspect ratio of your program
material. Cross conversions between 1080 and 720 HD formats are accomplished using a high quality
de-interlacing algorithm that permits all conversions to be performed in the progressive domain. In SD
formats, aspect ratio conversions between 4:3 and 16:9 are also easy to perform. In this example 486i59.94
with 16:9 aspect ratio is cross converted to letterbox 4:3 via SDI with embedded audio.
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 Input Aspect Ratio
Press the LBOX button to select letterbox, indicating that the input aspect ratio is 16:9.
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 486 button. The button is illuminated green. Note that the I button and the 59.94/60
button are also illuminated green. This is because interlaced video and 59.94 fields per second
are the only selections available for an NTSC 486 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.
Setting your Output 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 cross convert your video.
Press the IN button to see the format of the video signal that
you are converting. In this example, the format is 486i59.94
over SDI with embedded audio.
