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
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.
2 Select 'embed' as the audio input format.

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.
Setting your Input Aspect Ratio
Press the 'lbox' button to select letterbox, indicating that the input aspect ratio is 16:9.
Setting your Output
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 Teranex AV and Teranex Express, the 'embed' audio button will be blue.
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.
3 Using the soft menu buttons, select 'change'. The output video is now
displayed on the LCD and sent to all output connectors.
