Switch 5 - Component, Composite or S-Video
Set switch 5 to ‘off’ to select analog component video output, or ‘on’ for composite and
S-Video outputs.
To display the HD video input as SD on the S-Video and composite outputs, down conversion
must be set to ‘on’ by toggling switch 1. Component analog video supports both HD
and SD video.
Switch 4, 3 and 2 - SDI Audio De-Embed
Switches 4, 3 and 2 are represented as bits 2, 1, and 0 respectively. This simply means that by
setting various on/off combinations for switches 4, 3, and 2, you can choose which pair of audio
channels from your SDI input you would like to output to analog or AES/EBU audio.
The switch legend on the base of your converter gives you all the
information you need to change conversion settings.
Switch 1 - Processing Off - Processing On
Switch 1 lets you change the aspect ratio conversion that occurs when down converting Ultra
HD or HD inputs to SD analog outputs. This occurs because Ultra HD and HD formats are
presented in a 16:9 widescreen ratio of width to height, whereas SD is a taller 4:3 ratio.
The three options for aspect ratio conversion you can toggle through here are anamorphic,
center cut and letterbox. These stretch, crop, and add black bars to the top and bottom of your
image, respectively. To switch between these, simply toggle switch 1 on and off to move
through the available options. Each time switch 1 is set to ‘on,’ the aspect ratio type will move
ahead one option.
The behavior of switch 1 also changes depending on the analog output format you are using.
Composite video is always standard definition, so setting switch 1 to ‘off’ simply leaves the last
aspect ratio conversion option in place. However, component video can support a HD signal,
so when you are converting video from an SD source to a component output, setting switch 1
to ‘off’ will output a widescreen HD analog signal, with no aspect ratio conversion.
SDI Audio Selection Table
By using the following combinations of switch settings, you can select which SDI audio channels
to output as analog or digital AES/EBU audio with your Teranex Mini - SDI to Analog 12G.
