Quick Start Guides for LIS-SDI
Used as a line synchroniser with deglitcher.
1. Attach SDI input and SDI output(s) to the backplane module (see Figure 2 on page 8) and
attach the Black&Burst signal to the backplane. Terminate the Black&Burst signal with
75ohm to ground.
2. Set DIP-switch 1
on
(towards backplane). Set DIP-switch 3
on
. Leave the rest of the
switches untouched.
3. Insert LIS-SDI into a slot in the sub-rack.
4. Power on. After one second the LIS-SDI should be running, all LEDs should be green, see
section 5.2. Note that up to 12 seconds may be needed to synchronise SDI and Black&Burst
at initial power up.
5. The BCD switches and the pushbuttons
must
be used to adjust which line and sample the
output will lock to. The output phase must be set with respect to the Black&Burst signal in
such a way that the delay through the card is between 41 samples and 1 line and 41 samples.
(See section 4.3)
Used as a video deglitcher.
1. Attach SDI input and SDI output(s) to the backplane module (see Figure 2 on page 8) and
attach the Black&Burst signal to the backplane. Terminate the Black&Burst signal with
75ohm to ground.
3. Insert LIS-SDI into a slot in the sub-rack.
4. Power on. After one second the LIS-SDI should be running, all LEDs should be green, see
section 5. Note that up to 12 seconds may be needed to synchronise SDI output to the
Black&Burst input at initial power up.
5. The output from LIS-SDI is now delayed ca ½ line with respect to the SDI input. When a
upstream switch is performed and a SDI input with another phase is placed on the input. The
delay through the linesync is changed, but the output phase is the same. When in deglithing
mode, the different SDI inputs must not have phases that differ more than ± ¼ line.
Note that if a GYDA controller is used, switch 1 should be in the
off
position.
