3.2.4 Video Input Card
To integrate analog video, SDI video and HD-SDI video, there are different types of video input cards available for
use in the H
YDRA
C
OMPACT
. Each board except the Streaming video card is additionally equipped with a RJ45 GPIO
PIO
connector for user specified functions like tallies or alarms. Furthermore there is an LED for each input connector
to indicate, if there is a video connection or not.
Depending on the type of the video input card up to 40 video sources can be processed and displayed by one
H
YDRA
C
OMPACT
.
Order
The video input cards are inserted into the slots on the right of the overlay input card (looking from the back on
the H
YDRA
C
OMPACT
). The order of the various video input cards and the RGB input cards can be chosen arbitrarily.
GB input cards can be chosen arbitrarily.
One exception from this is the combination of Quad SDI video input cards and RGB input cards since the RGB
input cards can not be inserted directly to the left of the Quad SDI video input cards. Either a card of another type
can be inserted between these cards or the RGB input cards can be inserted to the right of the Quad SDI video
input cards.
There is no empty slot allowed between overlay input card and video/RGB input card
B input cards and
between the video/RGB input cards themselves!
Maximal number of video/RGB input cards
Using multiple input cards in the H
YDRA
C
OMPACT
some restrictions concerning the number of different types of
input cards must be considered. In the following formula
H
stands for the number of HD-SDI input cards,
V
for
Dual analog video input cards, Quad analog video input cards, Dual SDI input cards and Quad SDI input cards,
S
for Streaming video cards,
R
for RGB input cards,
O
for one channel output cards,
OD
DDda
for DVI-DVI
digital/analog output cards,
/analog output cards,
ODDd
for DVI-DVI digital output cards and
A
for the audio mother boards. The
following rule must be applied for a H
YDRA
C
OMPACT
with redundant power net:
25
≥
(H * 4.7) + 2 + (V * 3.1) + (S * 3.7) + (R * 2) + O + (ODDda * 2.5) + (ODDd * 0.5) + (A * 0.8)
With a non-redundant power net the following rule must be applied:
45
≥
(H * 4.7) + 2 + (V * 3.1) + (S * 3.7) + (R * 2) + O + (ODDda * 2.5) + (ODDd * 0.5) + (A * 0.8)
With non-redundant operation for all types of cards an unlimited number can be inserted except for the HD-SDI
input cards (at maximum eight pieces, depending on the other cards). With redundant operation limitations
apply also for other types of cards. In both cases always the whole configuration must be considered.
