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

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

Protocol 2000 for the SP-1G is described below. For RS-232, data is at 9600

baud, no parity, 8 data bits, and 1 stop bit. All values shown are hexadecimal.

Parameter Addresses

There are global parameters that are invariable in the case of a setup number change, and local parameters that have
appropriate E values for each setup number (16 different values, stored in special memory). During write or read operations
with local parameters, the PC gets access only to the active local parameter that corresponds to an actual setup number.
Certain local parameters (not all) are represented in two-byte format because of their large adjustment. To distinguish
between one-byte and two-byte parameters, as well as global and local parameters, the hex address of any parameter
(value "D"), contains a two-byte format flag – D7 (MSB) and a local parameter flag – D6.
All global parameters have the one-byte format, therefore their addresses (D7 = 0, D6 = 0) do not exceed 0x3f(hex) or
63(dec). One-byte local parameters (D7 = 0, D6 = 1) have addresses greater than 63(dec), but less than 128(dec). Two­byte local parameters (D7 = 1, D6 = 1) have addresses greater than 192(dec). Note that while writing or reading two-byte
parameters (PC -> machine), you must send two consecutive write or read commands (each command having a
conventional 4-byte structure) for low (first) and high bytes with a minimal time interval between them.
