Introduction
Welcometo KramerElectronics! Since1981, KramerElectronics has been providing a world
of unique, creative,and affordablesolutions to the vast range of problems that confrontthe
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, makingthe best even better!
Getting Started
We recommendthat you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Review the contents of this user manual.
Go to www.kramerav.com/downloads/KDS-10tocheck forup-to-date user manuals,
application programs, and to check if firmwareupgrades are available (where appropriate).
Achieving Best Performance
•Use only good quality connection cables (we recommendKramerhigh-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (oftenassociated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interferencefrom neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer KDS-10 away from moisture,excessive sunlight and dust.

Overview
Congratulations on purchasing your KramerKDS-10 4K Video Encoder/Decoder.KDS-10 is
an advanced, multi-standard, dual-stream transceiver forstreaming 4K@60Hz (4:4:4) video
signals via Ethernet over copper cable. KDS-10 can be set as either an encoder or decoder.
As an encoder, it encodes and streams one or two HDMI™inputs overan IP network. As a
decoder, it receivesthe encoded signal, decodes it and outputs it to an HDMIoutput.
KDS-10 features:
•AdvancedVideo Streaming Transceiver –Streams up to 4K@60Hz (4:4:4) resolution
signals overa 1G network interface,when streaming one source and 4K@30Hz (4:2:0)
when streaming two sources.
•Multi-Standard Video Coding –Configure the transceiversaccording to your needs to
stream using either H.264 or H.265.
•Flexible Input and Output Options –Includes two HDMIinputs that can be streamed
alternately or together.
•Streaming Support –Unicast and multicast over RTP(Real-Time Protocol).
•Flexible Analog Audio Embedding and De-embedding –When in encoding mode, you
can select the balanced analog audio input to embed into the streaming HDMIoutput
signal. When in decoding mode, you canextractthe HDMIaudio signal and output it as
balanced analog audio.
•Convenient and Comprehensive Control –Control the unit using intuitive embedded web
pages or Protocol 3000 API commandsviaEthernet.
•Simple System Management –Remotesystem management support to enable quick
and efficientremotesystem and device life-cyclemanagement.

Setting and Operating KDS-10
This section describes the KDS-10 setup encoder-decoder system. To set up the system,
perform the following actions:
•Configuring Network Switchto Multicast Modeon page 8.
•Setting the KDS-10 System on page 8.
Configuring Network Switch to Multicast Mode
Beforesetting up the KDS-10 encoder and decoder, youneed to configure a network switch
to stream in multicast mode.
It is important that youuse a 1G Managed switch with IGMP snooping layer2.
Toconfigure the switch:
1. Connect the switch to your PC.
2. Set the following:
▪JumboFrames –Off.
▪IGMP Snooping –On.
▪IGMP Querier –On.
▪IGMP Immediate/Fast Leave –Off.
Switchis configured.
Setting the KDS-10 System
This section describes the following KDS-10 setups:
•Setting a KDS-10 Encoder and DecoderSystem on page 8.
•Setting an Encoder with a Custom Decoder on page 9.
Setting a KDS-10 Encoder and Decoder System
By default, KDS-10 is configured as an encoder. When setting a KDS-10 encoder-decoder
system, youneed to set the decoder first.
Toconfigure the encoder and decoder:
1. Connect the encoder-decoder system (see Connecting KDS-10on page 6).
2. Connect a laptop to the network switch.
3. Makesure that power to the encoder is Off.
4. Turn the power on the decoder to On.

5. Definethe deviceas a decoder (see Setting KDS-10Configuration to Encoder/Decoder
on page 19).
6. Change the decoder IP address (see Setting DeviceIP Address and Other IP Settings
on page 23).
7. Definethe source (encoder) IP address and streaming port (see Defining Decoder
Streaming Settings on page 17).
We recommendthat forthe encoder you use the default IP address.
8. Power the encoder.
9. Makesure that the streaming channel appears on the display.
KDS-10 encoder-decoder system is configured.
Setting an Encoder with a Custom Decoder
You can use a KDS-10 encoder to stream to a custom decoder (forexample,using
MediaPlayer).
Toconfigure an encoder and custom decoder:
1. Connect the encoder to the same network as the decoder.
2. Turn the encoder power On.
3. Use the following URLtemplate to connectto a generated stream forboth unicast and
multicast streaming: “rtsp://ip_of_encoder:port_number/stream”.
For example, to generate a stream from the KDS-10 HDMI1 input, enter the following:
rtsp://192.168.1.20:554/stream.
