Making Video Reference Connections
The NV8288 and the NV8288-Plus provide timing reference connections for analog video signals,
labeled ‘VIDEO REF 1’ and ‘VIDEO REF 2’. The control card uses these references to perform
takes at the proper point in time (per SMPTE RP168), determining the router’s video frame switch
points. The video reference connections require a stable source of PAL, NTSC or Tri-level sync.
Both video reference connections use 75
ohm BNC connectors and coaxial cable. For a detailed
description of the video reference connections, see
Each ‘VIDEO REF’ connection can be use the same reference source (redundant) or two unique
reference sources (dual). For more information, see
If a video reference is present, signals switch at the defined frame and line switch points. If a video
reference is not present, the router still performs takes using an internally generated reference sig-
nal. If a video reference is not connected, the control card displays a lit red LED. (See
How to Make Connections to the Video References
1 Locate the video reference connections on the rear of the router, as shown in Figure 3-18. The
video reference connections are labeled ‘VIDEO REF1’ and ‘VIDEO REF2’.
