Safety Guidelines
Kraken User’s Guide, v2.6, Issue 02 3
Safety Guidelines
Use the following guidelines when unsafe conditions exist or when potentially hazardous
voltages are present:
●Always use caution and common sense.
●To reduce the risk of electrical shock, do not operate equipment with the cover
removed.
●Repairs must be performed by qualified service personnel only.
Antistatic Precautions
Electrostatic discharge (ESD) results from the buildup of static electricity and can cause
computer components to fail. Electrostatic discharge occurs when a person whose body
contains a static buildup touches a computer component.
The equipment contains static-sensitive devices that may be easily damaged, and proper
handling and grounding is essential. Use ESD precautionary measures when installing
systems or cards, and keep the parts and cards in antistatic packaging when not in use. If
possible, use antistatic floorpads and workbench pads.
Improper handling and/or installation practices may VOID the warranty.
CAUTION When handling components, or when setting switch options, always use an
antistatic wrist strap connected to a grounded equipment frame or chassis. If a wrist strap
is not available, periodically touch an unpainted metal surface on the equipment. Never
use a conductive tool, such as a screwdriver or a paper clip, to set switches.
Waste Electrical and Electronic Equipment (WEEE) Disposal
This symbol on Haivision products or packaging means that the product
should not be disposed of with general waste. It is your responsibility to
dispose of your waste equipment by handing it over to a designated
recycling collection point. The correct disposal of your end-of-life
equipment will help prevent potential negative consequences to the environ-
ment and human health.
In accordance with the European Union (EU) WEEE Directive, Haivision products that fall
within the scope of the WEEE, are labeled with the above symbol, and customers are
encouraged to responsibly recycle their equipment at the time of disposal. Haivision also
offers its customers the option of returning Haivision equipment to facilitate its environ-
mentally sound disposal.

New Features in Kraken v2.6
Kraken v2.6 introduces the following features:
Support Source Specific Multicast (SSM) (IGMPv3) Streaming from any
Ethernet Port
Kraken now supports IGMPv3 Source Specific Multicast reception. This means that input
streams may be configured to join a multicast group and filter the input streams based on a
specific source IP address. Only streams originating from the specified source IP will be
forwarded to Kraken. This allows Kraken to quickly and easily select an input stream in
environments with many sources sharing a common multicast IP.
MPEG-2 Video and Audio Encoding Support
Kraken now supports transcoding to MPEG-2 Video and MPEG-1 audio with closed
captioning pass-through. This allows Kraken to inter-operate with widely deployed legacy
systems.

Introduction
Product Overview
Kraken User’s Guide, v2.6, Issue 02 13
Product Overview
NOTE Transcoding is defined as the process of converting a media stream or object from
one format to another. This may be done in cases where a target device (or workflow)
does not support the format, has limited storage capacity or limited network bandwidth
that mandates a reduced stream size, or to convert incompatible or obsolete data to a
better supported or modern format.
Haivision’s Kraken Video Encoder/Transcoder delivers performance IP video transcoding.
Kraken is designed for Transport Stream to Transport Stream in enterprise or satellite video
distribution applications. The base model redistributes digital video broadcasts over enter-
prise networks. Kraken ISR (with ISR firmware option) provides low latency transcoding
for metadata-rich applications, such as within military Intelligence, Surveillance, and
Reconnaissance (ISR) full motion video applications.
Kraken Server is available in Base, Premium, and Ultra System appliance options (see
Figure 1-1 and 1-2).
Kraken CR (see Figure 1-3 and 1-4) is a small form factor H.264/HEVC
encoding/transcoding appliance. For details, see “Appliance Options” on page 19.

Product Overview
Kraken User’s Guide, v2.6, Issue 02 15
Kraken Enterprise – Distributing Streams for Enterprise
Kraken is used to groom high bandwidth broadcast streams for various destinations on the
network. It provides a solution to IP video deployments that capture digital video broad-
casts for redistribution over the LAN to enterprise viewers. For example, a set-top box such
as Haivision’s Stingray may consume 6 Mbps HD H.264 multicast streams, whereas a
desktop computer only 1 Mbps H.264 streams at a lower resolution.

Product Overview
Kraken User’s Guide, v2.6, Issue 02 16
Kraken ISR – Intelligence, Surveillance, and Reconnaissance
Kraken ISR is designed to collect, process, and disseminate information for full motion
video applications. This includes passing through MISP-compliant metadata, typically in
KLV (Key-Length-Value) format. Kraken ISR is optimized to disseminate information in
the formats required by downstream systems, networks, and viewers, while preserving any
required metadata with frame accurate synchronization.
Figure 1-6 Example Kraken ISR Scenario

Introduction
Kraken Features
Kraken User’s Guide, v2.6, Issue 02 17
Kraken Features
Kraken is designed to be used by consumers of HD video who are contending with high
bitrate / high quality streams that are either too big to transport over some network segments
or too costly for users’ end points to render the video smoothly.
As a transcoder, Kraken takes the stream from a source URL, re-encodes the audio/video,
and sends it out as a new stream with different encoding characteristics. The characteristics
that may be changed include Audio Bitrate, Video Bitrate, Video Resolution, Frame Rate,
Group of Pictures (GOP) size, and Maximum Transmission Unit (MTU).
As a baseband encoder (Kraken CR platform), Kraken captures and encodes/processes
baseband digital video, digital audio and ancillary metadata.
Kraken may be controlled and managed either through a Web interface or a Representa-
tional State Transfer (REST) Application Programming Interface (API). For details on the
API, please refer to the Kraken API Integrator’s Guide.
Audio/Video Characteristics
Kraken input streams are MPEG Transport Streams with the following characteristics:
●Video Codecs: MPEG-1, MPEG-2, MPEG-4, H.264 or H.265 (HEVC)
●Audio Codecs: AAC 2 channel, AAC 5.1 channel, AC3 2 channel, AC3 5.1 channel,
or MPEG 1 Layer 2
NOTE Kraken only supports Single Program Transport Stream (SPTS) inputs. Multi
Program Transport Stream (MPTS) inputs are not supported.
Output streams are MPEG Transport Streams with H.264 or H.265 (HEVC) video (Main
Profile 4.2 level maximum) and AAC 2 channel stereo audio. Any input stream that had a
mono audio source will have that source replicated into Left and Right stereo channels.
Audio may be disabled, which will remove any audio tracks on the output stream.
Transport Characteristics
Kraken input streams may be unicast UDP (the stream is sent to Kraken), UDP multicast,
TCP unicast (the stream is sent to Kraken), or TCP unicast (Kraken obtains the stream).
Input streams may be CBR, VBR or Constant Quantizer (ConstQ). The maximum
bandwidth of a single input stream is 20 Mbps.
Output streams may be Unicast UDP (the stream is sent to a third party device), TCP
Unicast (Kraken listens for a request), TCP Unicast (Kraken sends a stream to a third party
device), or UDP multicast. Output streams are VBR. The maximum single bandwidth for
an output stream is 20 Mbps. Note that Kraken requires a connection to a Haivision Furnace
server to integrate each TCP stream.

Introduction
Kraken Features
Kraken User’s Guide, v2.6, Issue 02 18
Kraken supports downscaling, de-interlacing, and selection of the frame rate in frames per
second to allow users to select the exact output frame rate for a transcoder session. Note
that “Auto” uses the same frame rate as the source stream.
NOTE The presence of Referenced B-Frames, streams without a “low-delay” bit set in
the stream, and/or streams where the audio and video are not interleaved can cause an
increase in latency.
SRT (Secure Reliable Transport)
Kraken supports Haivision’s Secure Reliable Transport (SRT) input and output streaming
format for interoperability with the Haivision eco-system. This enables end-to-end security
and stream resiliency for recording and streaming applications. For more information,
please refer to the SRTDeploymentGuide (available from the Haivision Download Center).
SRT is a transport technology that optimizes streaming performance across unpredictable
networks, including the public Internet, for secure, reliable, low latency HD video. SRT as
a protocol is included with Makito X encoders and decoders and Haivision’s Media
Gateway.
Console User Interface (Appliance Only)
A Console UI is available for Kraken appliances which may be accessed directly by
connecting a keyboard and monitor to the appliance (either from the front or the back of the
appliance), or through SSH. The Console UI allows administrators to perform basic system
administration tasks and network tests, as follows:
●Set basic network settings such as the IP address, netmask and default gateway.
●View statistics about the appliance’s health, including current IP address, Kraken
Version, CPU use, Memory use, and System uptime.
The Console UI requires a username and password. Console UI users will be able to change
their password.

Introduction
Appliance Options
Kraken User’s Guide, v2.6, Issue 02 19
Appliance Options
Kraken Server
Kraken Server is available in Base, Premium, and Ultra System appliance options.
●The Base System contains only one power supply and will therefore be affected by
power interruptions as a single point of failure. It supports up to 2x HD H.264/AVC
encoding channels only (no H.265/HEVC encoding), so is typically used where fewer
channels need to be transcoded. Its short-depth form factor makes it suitable for
applications and installations where space is limited.
●The Premium System provides redundant power supplies, so it can be plugged into
redundant power sources, ensuring higher availability. It supports up to either 8x HD
H.264/AVC encoding channels or 2x HD H.265/HEVC encoding channels, thereby
providing more transcoding channel density, enabling users to transcode more streams
and more outputs. It also features a short-depth form factor.
●The Ultra System also provides redundant power supplies. It supports up to either 16x
HD H.264/AVC encoding channels or 4x HD H.265/HEVC encoding channels,
thereby providing the most transcoding channel density. It is full depth.
The Ultra System also provides redundant Hot Swap Hard drives (RAID 1) and power
supplies.
All server appliances are 1RU tall. See Figure 1-1 and Figure 1-2 on page 13. For more
information, see “Physical Description (Kraken Server)” on page 20.
Kraken CR
Kraken CR, introduced in Version 2.2, is a small form factor H.264/HEVC
encoding/transcoding appliance, supporting capture of Analog Composite Video or
HD/SD-SDI digital. See Figure 1-3 and Figure 1-4 on page 14.
Kraken CR was designed to harmonize the user experience and functionalities between
Kraken and the Makito X platform. With the introduction of baseband capture and addi-
tional metadata functionalities, ISR customers can use Kraken not only as a GCS (Ground
Control Station) transcoder, but also as a source encoder.
For more information, please refer to the Kraken CR Installation Guide available through
Haivision’s Download Center.
