Page 22: Theory Of Operation
2: Rackmounting and Hardware Overview Theory of Operation VBOB is a digital video switcher that routes video inputs from different sources to various output formats. VBOB inputs include Serial Digital Standard Definition (SD) and High Definition (HD) BNC connectors, a Low Voltage Differential Signaling (LVDS) video input connector, and an optional dual-link Transition Minimized Differential Signaling (TMDS) input. -
Page 23: Lvds Interface
Genlock Genlock is a device that enables VBOB to receive an external sync signal, which locks the timing of the output video picture. This allows you to maintain a common timing across multiple video devices, which enables smooth dissolves, wipes, and other effects commonly used on broadcast TV. -
