2 SP-4D - 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
• Use only the power cord that is supplied with this machine
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).
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)
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
• Position your Kramer SP-4D away from moisture, excessive sunlight and
dust

SP-4D - Overview 3
3 Overview
The SP-4D 4-Channel HD-SDI Synchronizer is a synchronizer for serial digital
signals up to HD-SDI. The unit synchronizes up to four channels from the
dedicated digital genlock input or any other specified channel.
The multi-standard synchronizer SP-4D 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. Three groups contain mutually compatible
standards:
• 720p: 720p/50, 720p/59.95, 720p/60
• 1080i: 1080i/50, 1080i/59.95, 1080i/60, 1080psf/23.97, 1080psf/24,
1080psf/25, 1080psf/29.97, 1080psf/30
• 1080p: 1080p/23.97, 1080p/24, 1080p/25, 1080p/29.97, 1080p/30
Each of the four SDI channels contains a special audio synchronizer that de-
embeds all 16 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 SP-4D features:
• Multi-standard operation: SDI (SMPTE 259M and SMPTE 344M) & HDSDI
(SMPTE 292M)
• Four SDI video inputs and outputs (SD, ED and all HD, besides 1080p/50
and 1080p/60) with automatic standard detection (any video input can be
used as the timing reference input for all channels instead of the dedicated
genlock input)
• One dedicated SDI genlock input common for all four channels (also in the
same standard group)
• An audio embedder/de-embedder that handles 16 audio channels per input
4 SP-4D - Overview
• One VGA/UXGA port on a 15-pin HD connector (in YUV or RGBHV format
selectable from menu) to output any one of the four synchronized video
channels
• Unbalanced stereo audio outputs on RCA connectors that can output any of
the embedded audio channels
• A two-line, 20-character per line LCD display that shows the status of
machine while in the main mode of operation
• Seven front panel buttons that control operation of the machine
• Five LEDs that indicate input signal loss or genlock loss
• One RS-232 port for controlling the SP-4D from a serial remote control
device or a PC

5 Connecting the SP-4D
Always switch off the power to each device before connecting it to your
SP-4D. After connecting your SP-4D, connect its power and then
switch on the power to each device.
To connect the SP-4D, as shown in Figure 3
, do the following:
1. Connect up to four SDI input sources (for example, video cameras or a
digital video player) to the IN 1 to IN 4 BNC connectors.
2. Connect up to four SDI output acceptors (for example, a non-linear editor) to
the OUT 1 to OUT 4 BNC connectors.
3. Connect the GENLOCK IN BNC connector to an SDI genlock source (for
example an HD-SDI black-burst generator).
4. Connect the ANALOG OUT 15-pin HD connector to a computer graphics
acceptor (for example, an analog display).
5. Connect the AUDIO OUT RCA connectors to an audio acceptor (for
example, a stereo amplifier).
6. If required, connect the RS-232 9-pin D-sub connector to a controlling
computer (see Section
5.1).
