Input (and Output) Cards
in the absence of a valid signal. Inputs are self-terminating. After equalization, the SD video is
buffered to compensate for any loss accumulated in the path to the crosspoint/output cards via the
motherboard.
Figure 3-11 shows a simplified view of the SD signal flow:
Figure 3 -11. SD Video Signal Flow
SD Video Input Backplane
The SD input card uses the backplane. It has 16 BNC connectors. The SD input backplane is an
active module.
SWB Video
The NV5128-MC and NV5100MC frames differ in their support for SWB video.
The NV5100MC frame is newer and provides more throughput for HD channels. It supports any
number of SWB output cards. The limit is the number of output slots which is 8.
The NV5128-MC frame supports up to 4 of the older SWB output cards that mount in the wings of
MCPM-HDs, -HD2s, and -SDHDs (and SWB output modules). The NV5128-MC frame also
allows 1 (only) new SWB output card.
(Without the MFR, there is no reason to have any output cards of any kind.)
Old SWB 16-Input Backplane and Input Modules
The SWB input card accepts a wide range of data rates, both HD and SD.
The SWB backplanes contain active circuitry that performs cable equalization.
SWB input cards support 16 inputs. An SWB input card buffers the automatically equalized inputs
from the backplane and feeds the 16 input signals to the motherboard.
New SWB 16-Input Backplane and Input Modules
The SWB input card accepts a wide range of data rates, both HD and SD.
The SWB backplanes contain active circuitry that performs cable equalization.
SWB input cards support 16 inputs. An SWB input card buffers the automatically equalized inputs
from the backplane and feeds the 16 input signals to the motherboard.
The new input cards can feed more than one MCE.
S
At least one SWB input card (and backplane) is required if the frame is to support an Intuition
XG subsystem.
Old SWB Output Module
The NV5000-HD-OUT is a special card that plugs into a wing slot of an MCPM-HD, -HD2, or
-SDHD. The NV5000-HD-OUT also fits in the wing slots of an
NV5000-HD-XPT/OUT
output mod-
ule (when an MFR is present).
