1. Overview
The ENC-200™ real-time encoder is designed for LIVE streaming applications such as LIVE TV or
video transmission, video trunking, IPTV encoding, remote monitoring feeds, video collaboration and
is also used as the ingest for LIVE and VOD video publishing systems.
Real-time LIVE streams from ENC-200™ encoders can be viewed on PC’s by using Teracue’s
XPlayer™ software player. TV’s, LCD’s, plasmas, monitors, can join the transmission streams with the
robust DEC-200™ decoder. Consumer and PC-based displays can cost-effectively receive ENC-
200™ streams with set top boxes.
To record and preserve LIVE feeds for later viewing, analysis or simply archiving the iCue™
Streaming Server has been designed.
ENC-200™ encoders incorporate low-latency compression technology and professional signal
processing, creating full resolution and smooth motion DVD-quality video streams.
Connect LAN Ethernet and a video/audio input signal and the ENC-200™ encoder will turn into a true
video networking ‘port’, transmitting your video in digital form over IP networks.
To access the intuitive graphical user interface use your standard web browser from any PC on the
network, no special or additional tools are required. Remote network configuration is also supported
over Telnet, as well as serial control over the local Comport.
All ENC-200™ process input streams in up to full DVD-quality for professional MPEG-4 AVC H.264
SD streaming to any kind of device. ENC-200™ encoders are built for robust 24/7 LIVE encoding
operations and can be used in tough environmental conditions. They are designed without any moving
parts, making them disk-, fan- and noiseless.
ENC-200™ combines high-performance with unparalleled simplicity in a compact Ethernet video
encoding appliance designed for commercial, institutional, and industrial applications such as:
 Broadcast/TV Distribution over IP
 IPTV/Confidence Monitoring
 Security/Surveillance/Monitoring/Public Safety
 Medical/Corporate/Military/Industrial-Training
 Education/Distance Learning/Tele-Teaching
 Finance/Brokerage Television
 Legal/Legislative Communications
 News/Sports/Advertising Agencies – Air/Rail station advertising
 Manufacturing/Process Monitoring
 Hospitals/Clinics/Telemedicine
The ENC-200™ blades are operated inside the FR chassis series. Blades can be used in the FR-110
single channel chassis or in the FR-210 dual channel chassis. High density requirements are solved
by operating the ENC blades in the FR-2000 multi-channel rack, which can hold up to max. 21
Teracue blades. Different types of ENC encoder blades, DEC decoder blades and DVB/IP video
gateways can be ‘mixed and matched’ inside the FR-2000 chassis.

2. General Information
You can operate the ENC-200™ blades in the FR-110 single blade chassis, in the FR-210 dual blade
chassis or in the FR-2000 multi-channel rack chassis. For example when only a small amount of
encoders is required, or if single channel encoders need to be set up at dispersed network locations.
All equipment (like the chassis) and ENC-200™ accessories are handled as model options and need
to be purchased separately.
2.1 Unpacking the Encoder
When you unpack the ordered equipment, please make sure that all the equipment is complete.
Normally the ENC-200™ blades are pre-fit into the according chassis that the encoders have been
ordered with.
If ENC-200™ blades are ordered and shipped separately, please be careful when handling the blades.
Be sure to avoid electrostatic influence when touching the blades.
After unpacking, your ENC-200™ should include the following:
 1 x Teracue DVD which includes this user guide
 1 x ENC-200™ H.264 Encoder blade
 1 x Breakout cable ‘S’
2.2 Setting up the Encoder and Safety Instructions
Always read the instructions carefully and keep this user guide for future reference.
Please choose a suitable location for operating the encoder(s).

2.3 Connecting the Encoder (FR-110 chassis)
Please pay attention about the cabling order between the power supply and the FR-chassis. Connect
at first always the connector of the power supply to the FR-chassis.
The cable connector can be locked to the socket of the encoder, so the cable cannot accidentally be
pulled out [Bayonet Socket]. To do so the connector has to be placed on the socket and lightly turned
90° in a clockwise motion.
After you have connected the connector of the power supply to the chassis, please connect the power
cable to the power supply.
As next, please connect the network cable to the network interface and connect your video source unit
to the video input of the ENC-200™. Concerning of the video input you have the choice between
different video signal types. The ENC-200™ supports SDI (with embedded audio), Composite, S-
Video, YPbPr signals. If you have a Composite (CVBS), S-Video (YC) or a YPbPr signal, please use the
Sub-D 26-pin connector via the breakout cable. If you have a SDI or Composite signal, please use the
BNC connector.
Furthermore, if you have analogue audio, please use the Sub-D 26-pin connector via breakout cable.

3. ENC-200™ User Guide
This chapter gives you an overview over ENC-200™ and demonstrates the encoder's main functions.
.!. Before proceeding please be sure that the encoder is setup correctly and all necessary
connections are established.
Working and configuring Teracue's encoders is very easy.
You do not need to install an application or remote configuring software. If you know how to browse
the internet, then you already know how to access and control the encoders, simply via web-browser.
3.1 Accessing and Configuring Encoders
Open your standard web-browser and enter the encoder's IP-address (e.g. ‘172.16.20.100’) in the
address field and press the ‘Enter’ button.
.!. If you haven't changed the factory presets and if not specified elsewhere in the
shipment the encoder's IP-address will by default be set to: 172.16.20.100.
Default IP-address:
172.16.20.100
Login username:
admin
Login password:
admin
.!. The encoder is configured by factory default to automatically start the encoding
process and streaming the video with the multicast address 239.252.20.100, when a
video is connected and a network link is established.
.!. To be able to login to the encoder's user interface, your computer has to be in the same
IP-address range (subnet).
.!. Lower firmware versions than the version 0.9.15 have another default IP-address,
please see therefor also chapter 6 on page 57.
You briefly might have to change your computers IP-address to be in the same subnet as the encoder.
Only then you will be able to access the encoder and change the encoder's IP-address, and of course
afterwards change your computer's IP-address back.

3.3.2 ‘APPLY’ and ‘SAVE’ Buttons
A change or multiple changes of the configuration settings will only take effect
after the ‘> APPLY’ button is pressed.
The encoder will then start working with the new parameters, but the parameters
will not be saved to the encoder. Applied settings are not saved and will be lost
after a reboot.
Good for quickly testing and applying different settings.
Same as the ‘> APPLY’ button, but the configuration parameters will be applied
and saved to the encoders flash memory.
Saved parameters will be used by the encoder even when the encoder is turned
off & on or after a reboot has taken place.
Good for permanently saving the encoder configuration.

3.4 Encoder Configuration
3.4.1 Menu: Encoder / Settings
Under the menu option ‘ENCODER/SETTINGS’ you define the main operational state of the encoder.
Here you can set encoding process to ‘On’ or ‘Off’. See Figure 6.
Figure 6: 'Encoder / Settings' page of the ENC-200™ encoder
Settings: Description:
Page Refresh: Enables / Disables the refreshing of webpage every 10 seconds.
Encoder Start: Stops or starts the encoding process.
Stream Mode: Specifies the stream mode of the transmitted stream.
You can
choose between:
 TS (Transport Stream)
 TS/VIDEO (Transport Stream Video Only)
 TS/AUDIO (Transport Stream Audio Only
 VES (Video Elementary Stream)
 AES (Audio Elementary Stream)
Padding: Specifies the padding mode. You can choose between:
 ON (is recommend when a constant data rate is needed)
 OFF (the transport stream has a variable data rate
. All
settings in the ‘VBV size’ field of the ‘video’ webpage have
no effects)
 LOWDELAY (
the transport stream has a variable data
rate with enabled ‘Low Delay’ mode with the lowest delay.
A
ll settings in the ‘VBV size’ field of the ‘video’ webpage
have no effects.)
.!. ‘LOWDELAY’ will create non-ISO standard
TS
streams, but can reduce the delay.
To support
‘LOWDELAY’, the decoding side of your streaming
chain (i.e. decoder or STB) needs to be able to handle
the PTS and DTS codes as ISO/standard streams.

ENC-200™ H.264 Encoder
User Guide V1.8
18
Transport Protocol: Specifies the transport protocol.
You can choose between the
connectionless protocol UDP and the connection-
oriented protocol
TCP. If you use TCP, your destination must also
support TCP.
Furthermore, no multicast is supported when using TCP.
If you
choose ‘TCP/SERVER’, your destination must be the client. If you
choose ‘TCP/CLIENT’, your destination must be the server.
For
more information, please see chapter 4.3 on page 49.
.!.
If network errors occur in your network, we
recommend using TCP protocol.
Transportrate [kbps, 0=auto]: Specifies the transport rate. The value ‘0’ indicates the automati
c
mode for the transport rate. The transport rate consis
ts of the
video bitrate, the audio bitrate and an overhead.
Please see also
Table 6.
.!. We recommend using the
value ‘0’ for the automatic
mode.
.!. Between the transport r
ate, the enabled padding
mode and the VBV buffer exists a closed relation
and their settings have an effect to the video.
Therefore we recommend the following:
 Big transport rate value → Small VBV buffer value
 Small transport rate value → Big VBV buffer value
VideoLoss: If the video input signal is lost, you can choose here a screen
which should streamed out. Following screens are available:
 OFF
 BLACK SCREEN
 GREY SCREEN
 COLORBAR
If ‘OFF’ is chosen, the encoder stops the streaming when the
video input is lost.
The ‘Video loss’ function is supported for SDI
signals and analogue video signals.
Input locked: Displays the status of input video (Read only)
. ‘YES’ indicates that
video input is OK. ‘No’ indicates that video input is missing.
Transportrate: Displays the actual stream transport rate when ‘ON’ as ‘Padding
’
is chosen. I.e. the network bandwidth of the stream.
(Read only
field)
Bytes Transmitted: Displays the number of Bytes that have been transmitted
. (Read
only field)

.!. Occurrence of errors at the ethernet connection: These errors are mostly a combination
of packet losses, permutations, bit errors, dalay / round-trip time, jitter etc. The
performance of the TCP error correction strongly depends on the round-trip time. If you
use TCP with a sendbuffer size of 250.000 and your round-trip time is not bigger than 60
msec., the ENC-200 absorbs packet losses of 3%. If you use TCP with a sendbuffer size
of 250.000 and your round-trip time is not bigger than 300 msec., the ENC-200 absorbs
packet losses of 1%.

Settings: Description:
Codec: Displays the video codec of the output stream. (Read only)
Profile: Specifies the used H.264 profile. You can choose between:
 Baseline
 Main
Bitrate: Specifies the video bitrate in kBit/s of the output stream.
Intra Frame Interval: Specifies the interval of the intra frames. Intra frames (= I-Frames)
are total in
dependently coded frames which are used as
references frames.
Additional Information about P-Frames and GOP length:
At the ENC-200™ the data volume of a P-
Frame amounts
between 5% and 20% of an I-Frame.
If is assumed of an average
data volume of 10%, it means that for one I-Frame or ten P-
Frames the same data volume is needed.
The H.264 standard
allows long GOPs. The ENC-200™
limits the GOP length to 500
frames. More P-Frames at the same
data rate means also a better
quality. But more P-Frames have also tw
o disadvantages: 1) The
decoder can start the decoding process
not till then the decoder
get an I-Frame.
That means at a GOP of 500 frames, the decoder
waits in worst case 20 seconds before a picture can be displayed.
2) The result of this is also, that at occurrence
of network errors
(high packet loss), Frame gaps of up to 20 seconds can occur.
So,
the lower the P-
Frames, the higher are the robustness and the
faster can be switched the streams.
Deinterlacing: Enables / Disables deinterlacing.
Input: Specifies the video input which is available on the Sub-D 26-
pin
connector or on the BNC connector of the front panel.
 SDI (via BNC on the front panel; note here chapter 4.5)
 CVBS(BNC) (via BNC on the front panel; note chapter 4.5)
 CVBS (via breakout cable)

.!. Changes in this field require a reboot.
Format: Specifies the colour encoding system of the video input.
You can
choose between PAL and NTSC.
.!. Changes in this field require a reboot.
Aspect Ratio:
Specifies the aspect ratio. If an analogue input signal includes the
WSS (Wide Screen Signal) the encoder
can detect whether the
input signal is in 16:9 or in 4:3, when menu ‘Aspect Ratio’ is
switched to ‘AUTO’.
In the PAL standard video signal the wide
screen signal is included in the first half of line 23. In the NTSC
standard video signal the wide screen signal is included in the first
half of line 21. If your video source does not include the
WSS in its
analogue output signal, although you have a ’
16:9’ signal, you can
manually switch in this field the encoder to ’16:9’ or ‘4:3’.
Resolution: Specifies the video encoding resolution. You can choose between
full D1, half D1 and SIF/CIF resolution.
Full D1, Half D1 and
SIF/CIF streams can have a min. bandwidth of 500 kBit/s.
VBV size in ms: Specifies the input-
and output buffer of the encoder and decoder
and have an effect directly to the delay.
.!. We recommend a VBV buffer size of 2500 msec. H
ere
you are very safety.
.!.
For a small delay you can set the VBV buffer up to 800
msec.
, but when the video content is complex, it is
possible that a buffer overfl
ow occurs and because of
this the stream is faulty.
.!. Between the VBV buffer, the e
nabled padding
mode and the transport rate
exists a closed
connection and their settings have an effect to the
video. Therefore we recommend the following:
 Big VBV buffer value → Small transport rate value
 Small VBV buffer value → Big transport rate value
.!. This field have only an effect when padding is ‘ON’.
Deblocking:
Enables / Disables the deblocking function. You can choose
between:
 AUTO
 OFF
Encode Mode: Specifies the encoding mode. You can choose between:
 AUTO (Decision via visual conten)
 PROGRESSIVE
 INTERLACED
