2 SP-1G - Getting Started
2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
Use Kramer high performance high resolution cables
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs and to check if firmware
upgrades are available (where appropriate).
Caution: No operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning: Disconnect the power and unplug the unit from the
wall before installing
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer SP-1G away from moisture, excessive sunlight and
dust

SP-1G - Overview 3
3 Overview
The SP-1G 3G HD-SDI Synchronizer is a synchronizer for digital video signals up
to 3G HD-SDI. When Genlock is active, the device converts any SDI input
standard to any SDI output standard within compatible groups, scales the image,
and synchronizes with a video channel from the dedicated genlock input - either
an SDI input or an analog reference source. When the Genlock is inactive, the
device converts any SDI input standard to any SDI output standard, scales the
image, and synchronizes a video channel from the dedicated genlock input.
Input and output Video Standards (SMPTE 292M, SMPTE 259M and SMPTE
424M compliant): 480i/60, 576i/50, 720p/50, 720p/59.95, 720p/60, 1080i/50,
1080i/59.97, 1080i/60, 1080p/23.97, 1080p/24, 1080p/25, 1080p/29.97, 1080p/30,
1080p/50, 1080p/59.97, 1080p/60, 1080psf/23.97, 1080psf/24, 1080psf/25,
1080psf/29.97 and 1080psf/30.
The multi-standard synchronizer SP-1G can convert the frame rate of HDTV
signals without changing the number of lines per frame or the progressive–
interlaced raster structure. It implements cross-conversion between any two
standards belonging to the same group when the Genlock is active. Three groups
contain mutually compatible standards:
•720p: 720p/50, 720p/59.95 and 720p/60
•1080i: 1080i/50, 1080i/59.95, 1080i/60, 1080psf/23.97, 1080psf/24,
1080psf/25, 1080psf/29.97 and 1080psf/30
•1080p: 1080p/23.97, 1080p/24, 1080p/25, 1080p/29.97, 1080p/30,
1080p/50, 1080p/59.97 and 1080p/60
The unit contains a special audio synchronizer that de-embeds all input audio
channels, resamples them simultaneously, and embeds the resulting audio signals
in the SDI output. This corrects signal deterioration such as a frame drop or
repetition that may occur during video signal synchronization.
The SDI video signal that is applied to the genlock SDI input can also be used
(without external connections) as a third video input. Thus the SP-1G, besides its
synchronizing function, can implement Clean Switching (glitch-free) video and Soft

4 SP-1G - Overview
Switching audio between three separate non-synchronous SDI inputs even if the
standards of these signals differ, as long as they belong to the same group.
More specifically, the SP-1G features:
•Cross standard conversion
•Image scaling
•Two SDI inputs and outputs
•One dedicated SDI genlock input and one analog genlock input with LOOP
output
•Clean Switching video (glitch-free switching) and Soft Switching audio
functions
•Automatic standard detection
•TBC operation with continuous, uninterrupted syncs on the output, even
when there is an input glitch
•An audio embedder/de-embedder that handles 16 audio channels
simultaneously
•A built-in test signal generator that provides special video test signals as well
as a 1kHz (–18dBFS) audio sine wave for all 16 SDI audio channels (all 4
groups simultaneously)
•A two-line, 16-character per line LCD display that shows the status of the
device while in the main mode of operation
•Nine front panel buttons to control operation of the device
•One RS-232 port for controlling the SP-1G from a serial remote control
device or a PC

The SP-1G can be used as a clean switch as shown in the application in Figure 3.
To connect an 8x1 clean switch:
1. Connect the SDI OUTPUT of a switcher (for example, a VS-81HDxl) to the
SDI INPUT of the SP-1G.
2. Connect the SDI OUTPUT of the SP-1G to an SDI acceptor (for example, a
non-linear editor).
3. Configure the internal genlock of the SP-1G to INPUT 1 (see Section 6.6.3).

4.1 Connecting the SP-1G via RS-232
You can connect to the SP-1G via an RS-232 connection using, for example, a
PC. Note that a null-modem adapter/connection is not required.
To connect to the SP-1G via RS-232:
•Connect the RS-232 9-pin D-sub rear panel port on the SP-1G via a 9-wire
straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5 need to be
connected) to the RS-232 9-pin D-sub port on your PC

SP-1G - Operating the SP-1G 9
5 Operating the SP-1G
This section explains how to use the:
•LCD display (see Section 5.1)
•Front panel buttons (see Section 5.2)
5.1 Using the LCD Display
The SP-1G includes a two-line, 16-character per line LCD display that displays
(while in the main mode of operation) the device status, the genlock reference
source and standard of video signals on SDI outputs. The following examples
explain what is shown on the display.
1. When the genlock mode is turned OFF, the display shows:
SET3 INT.XTAL REF.
FrcSTD:1080p/60
This means the setup (preset) number is 3; the internal crystal generator
XTAL is used as the genlock reference source, the standard of output
signals on outputs is forced to 1080p/60.
2. If the genlock is turned ON and a reference input signal was selected as
dedicated input SDI GenlockIN, the display shows:
SET3 Ref: GnlSDI
FrcSTD:1080p/60
3. If the output standard selection mode is AUTO, the display shows:
SET3 Ref: GnlSDI
AutSTD: 1080p/60
4. If genlock is turned ON and Analog Genlock Input was selected as the
reference input signal, the display shows:
SET3 Ref: GnlAnl
AutSTD: 1080p/60
