2.4 DVP-101i Electrical Installation
When connecting the DVP-101i to external equipment, make sure that all serial digital
connections are point-to-point. For instance, there must be a point-to-point connection
between a
4:2:2 OUT
BNC and target equipment. If a T-connector is used to connect
other equipment, the maximum specified cable length is no longer valid.
Also, make sure that the cable lengths of the output serial digital cables are a
maximum 250m (850') each. Refer to Figure 2.7 and to the following descriptions for a
complete DVP-101i electrical installation.
4:2:2 IN - serial digital input
Connect a serial digital video signal, conforming to the SMPTE 259M-C standard to
the BNC labeled
4:2:2 IN
. The DVP-101i will automatically switch to the detected line
format and turn on the corresponding LED on the module’s front end (figure 3.1).
Studio reference input with loop-through output
For external synchronization, connect the studio reference signal to the BNC labeled
REF IN
. The DVP-101i accepts SMPTE 170M/PAL ITU 624-4 or 2 Vpp/4 Vpp compo-
site sync reference signals. When using the Quartet, Quartet-C, Solo or Symphonie-
R-C, the DVP-101i provides a loop through output of the studio reference signal.
Make sure to terminate this output with a 75
Ω
terminator when it is not being used.
A valid analog composite reference signal will turn on the REF indicator located on the
module’s front end (figure 3.1). The reference signal must be NTSC for 60 Hz sources
and PAL for 50 Hz sources. If there exists a line format mismatch between the
reference input and the 4:2:2 input, the REF indicator flashes.
4:2:2 OUT 1 and 2 - serial digital video outputs
The DVP-101i provides 2 video output BNCs. These BNCs, labeled
4:2:2 OUT 1
and
2
provide the decoded video signal conforming to the SMPTE 259M-C standard.
Composite
outputs
Composite signals are provided on the BNC connectors labeled
COMPOSITE OUT 1
and
2
. Output format is user-selectable, NTSC for 525-lines format operation or PAL
for 625-lines format operation.
Delay – video processing delay signal and GPI output
When using a Quartet-M or Symphonie-R-M, the DVP-101i provides a video
processing delay signal through an RJ-45 connector using RS-422A transport
standard. The video tracking delay is a signal that specifies the current processing
delay of the card. It indicates to an audio processor the amount of delay that must be
added in the audio path to compensate for the video processing delay and frame sync
function to avoid lip sync problems.
Connector pinout is detailed on Figure 2.6. (When
using the DAP-711i/712i as audio processors, install the DAP module(s) in the same
