This chapter shows you how to connect the DG5-2/TVO board to VBOB for High Definition or Standard Definition graphics video output and genlock synchronization.
To display graphics images in High Definition or Standard Definition video, follow these steps:
Connect one end of the TMDS A cable (black cable with white connector on each end) to the TVO board's TMDS A connector. Attach the other end of this cable to the VBOB TMDS A connector, as shown in Figure 2-1.
Connect one end of the TMDS B cable (black cable with black connector on each end) to TVO board's TMDS B connector. Attach the other end of this cable to the VBOB TMDS B connector.
Connect one end of the BNC Timing Reference cable to the VBOB Timing Out connector. Attach the other end of this cable to the TVO board's Genlock in connector.
Connect the 75 Ohm terminator to the Genlock loop-through connector on the TVO board.
![]() | Note: VBOB has two BNC connectors for each external HD and SD genlock. You can use either of these connectors as an input or a loop-through. |
After you complete the above connections, connect the required cable(s) from the VBOB HD out or SD out connector(s) to the desired High Definition or Standard Definition video device(s).
If you want to lock the output serial digital signals to an external genlock signal, connect an analog sync source to the VBOB HD genlock in or SD genlock BNC connectors (see Figure 2-2). If you are not using High Definition or Standard Definition genlock loop-throughs, attach a 75 ohm terminator to the appropriate connectors.
