Gearbox Configuration and Operation
The gearbox in each camera chain in the SilverBack V base unit receives the main camera video stream
from the camera unit and de-multiplexes it back into its original video format.
The gearbox mode must be configured to match the type of output the camera is providing, which will
be either a single-link, dual-link, or quad-link signal. The default setting from the factory is Quad 3G.
Output Mode Description
Single Link The base unit outputs a single HD, 3G, 6G or 12G stream.
Dual Link 3G The base unit outputs a dual-link 3G stream (6G total).
Dual Link 6G The base unit outputs a dual-link 6G stream (12G total).
Quad Link HD The base unit outputs a quad-link HD stream (6G total).
Quad Link 3G (default) The base unit outputs a quad-link 3G stream (12G total).
The gearbox relies on SMPTE S352M PID metadata embedded in the camera’s output video stream to
process the signal correctly. In some cases, PID metadata from the camera may be missing or incorrect,
which can cause incompatibility with the gearbox.
The PID Mode setting is used to configure how the gearbox processes the PID metadata from the
camera. In most cases, the default setting of Auto should be used.
Auto PID Mode Description
Enable (default) Automatically determine video format conversion and PID conversion
modes based on incoming PID information and Output mode setting.
Disable The gearbox will output video using the selected Output mode but will
maintain original PID information from the camera.
The gearbox has certain limitations as to which camera video formats can be converted between single-
link, dual-link, and quad-link video streams. The gearbox cannot convert Square Division (SD) camera
formats into a 2SI formats, nor can it convert Level-B formats to Level A. Only 2SI Level-A camera video
streams are capable of being converted between single-link, dual-link, and quad-link. The gearbox can
accept and transport SD and Level-A camera formats; however, they must always be de-multiplexed in
the gearbox in the base unit back to their original format.
The gearbox for each camera chain is configured from the Video Settings menu:
