AvediaStream e25xx and e35xx Encoders V1.4
1 Getting Started
AvediaStream Encoders create a single IPTV stream on your building, campus or
metropolitan-area IP network from the output of various video devices. You can use them to
distribute the output from a variety of Standard Definition and High Definition AV devices such
as video cameras, DVD players, set-top boxes and professional SDI feeds.
The AvediaStream e35xx encoders accept HD content inputs (up to 1080p 50/60Hz for
e3532/e3535 and e3552/e3555) and allow full resolution encoding in the output transport
stream. AvediaStream e35x2 encoders allow scaling of both resolution and frame rate in the
output stream to values the same as, or lower than the input signal. The e3535 and e3555
allow scaling of any input to any output resolution and frame rate up to 1080p 50/60Hz.
The AvediaStream e25xx encoders accept SD and HD inputs (up to 1080i) and deliver an SD
(525i/625i) output transport stream.
Refer to Table 5 on page 14 for more information about input resolution and frame rate
capabilities.
The following procedures must be performed for the encoder to perform correctly. These
procedures are summarised in this section:
1. Connecting the AV Source
Before the encoder can stream audio/video on the network, an AV source must be connected.
See Physical Interfaces on page 12 for details on how to connect your AV equipment to the
encoder.
2. Connecting to the Network
Connect the encoder to the network.
For more information, see the AvediaStream Installation Guide.
3. Connecting to Power
Connect the encoder to a power source.
For more information, see the AvediaStream Installation Guide.
4. Configuring the IP Address of the Encoder
By default, the encoder requires a DHCP Server to be available on the network to assign it an
IP address.
There are two methods of assigning a static IP address to the encoder, if required:
●
Use the serial Admin Interface to configure the IP address. For more information refer to
Admin Interface on page 24.
●
Temporarily set up a DHCP server on an isolated network. Once an IP address is
assigned to the encoder, you can configure a static IP address using the Web
Management Interface. For more information refer to Network Configuration on page 26.
Allocating a static IP address for the encoder allows continued operation without a DHCP
Server.
10
Administrator’s Guide
AvediaStream e25xx and e35xx Encoders V1.4
5. Naming the Encoder
Provide a name for the encoder so you can easily identify it in the future. This can be done
using the Web Interface General Page (shown in Figure 12 on page 25) or the AvediaServer
Director application (shown in Figure 10 on page 23).
6. Configuring Audio/Video Input
The device starts encoding and streaming automatically when an appropriate AV source is
connected. It may be necessary to configure the type of video source connected. Refer to
Encoding and Streaming on page 37 for more information.
7. Configuring Encoding Options
The device starts encoding automatically when an appropriate source is connected. Some
aspects of the encoding can be configured if required. The encoder starts streaming
(transmitting an MPEG transport stream on the IP network) automatically when an appropriate
source is connected. Some aspects of the stream can be configured if required. For more
information refer to Encoding and Streaming on page 37 and to Stream Properties on page 60.
8. Configuring Channel Announcements
The encoder uses SAP (Session Announcement Protocol) to announce its stream (channel) to
receiving devices. Included in the announcements are the name of the channel and the
multicast address and port on which the stream is sent. This is done automatically once the
encoder is up and running.
You can configure channel announcements to suit your requirements. For more information
refer to Channel Announcements on page 68.
9. Checking Status
You can check the operating status of the encoder and that the encoder is transmitting data at
the rate expected by the streaming settings. For more information refer to Status Monitoring on
page 72.

Administrator’s Guide
AvediaStream e25xx and e35xx Encoders V1.4
Device IP addressing
You can configure the encoder to obtain an IP address automatically using DHCP, or you can
specify static addressing information i.e. IP address, subnet mask and default gateway.
Note: After applying an IP addressing change, this change takes effect after a short time and
the device starts using the new IP address. No reboot is necessary.
To configure the encoder to be allocated an IP address automatically:
1. Click Network.
2. In the IP Address Configuration section, click Automatically using DHCP.
3. Click the Apply button.

Ethernet settings
The encoder can automatically negotiate any combination of 10/100 Mbps and half/full duplex
with an Ethernet switch. It is also possible to disable auto-negotiation, resulting in a fixed
setting of 100Mbps full duplex (100FD).
The default setting is On (Auto-negotiation enabled).
It is important to ensure that the encoder settings match the settings on the switch port to
which the encoder is connected. If this is not the case, the result can be dropped packets
causing breakup of audio/video.
In practice this means the AvediaStream encoder and the connected network switch should be
configured for operation as follows:

Auto-negotiation enabled on both the AvediaStream encoder and the connected
network switch.

Auto-negotiation disabled on both the AvediaStream encoder and the connected
network switch, and a fixed setting of 100FD (Full Duplex) configured on the switch.
It is not recommended that the encoder is connected to a half duplex Ethernet port.
To enable/disable Ethernet auto-negotiation:
1. Click Network.
2. In the Network Port Configuration section, choose on or off as appropriate from the

● e3550 - SDI SMPTE 259M and SMPTE 292M
● e3552/e3555 - SDI SMPTE 259M, SMPTE 292M and SDI SMPTE 424M
24/60Hz Frame Rate
The e2552/e3550/e3552/e3555 AvediaStream encoders are compatible with SDI sources
which have output frame rates of 23.98Hz, 24Hz, 50Hz, 59.94Hz, and 60Hz. HD material can
either be true 24/60Hz, or may be offset by a 1/1.001 divider to give 23.98Hz or 59.94Hz.
The encoder automatically detects the frame rate and no configuration is required. However,
under certain circumstances the encoder may not be able to distinguish between 59.94Hz and
60Hz or between 23.98Hz and 24Hz. In this case you must manually select the appropriate
setting. The default setting is Automatic.
To specify the Frame Rate:
1. Click Input.
2. Choose an option from the 24/60Hz Frame Rate drop down list.
3. Click the Apply button.

output without modification. When Re-clocked loop-through is selected, the input signal is
processed to reduce jitter.
While the Re-clocked loop-through process delivers a better quality signal at the output, the
timing is affected and the output signal is out of phase with the input. Simple Loop-through is
more likely to suit environments where the timing of different SDI feeds is critical.
The default setting is Disabled.

Encoding – General
The device encodes video in H.264 format. The video can be encoded at constant bit rate
(CBR) or variable bit rate (VBR). For a CBR stream, the encoding bit rate can be configured.
For VBR, the maximum and average encoding bit rates can be configured.
Note: It is possible that the configured bit rate may not be the bit rate used for the encoding, as
the encoder has minimum and maximum limits based on the resolution of the connected video
source. The actual encoding bit rate is displayed on the Status page. Refer to Status
Monitoring on page 72 for more information.
The default settings are:
● CBR 15Mbps - AvediaStream e2522, e2532, and e2552
● CBR 20Mbps - AvediaStream e3520, e3522, e3530, and e3550
● CBR 24Mbps - AvediaStream e3522
● CBR 30Mbps - AvediaStream e3532,e3535, e3552 and e3555
For best picture quality, use CBR at the highest bit rate compatible with your system capacity.
For best use of bandwidth use VBR and/or a lower bit rate, although this can result in
degradation of picture quality.
Encoding – AvediaStream e2522/e2532/e2552
By applying the H.264 Scalable Video Coding (SVC) extension capabilities of the e2522,
e2532, and e2552, you can scale any input signal (up to 1080i 60Hz) and output it as an SD
(525i/625i) transport stream with bit rates ranging between 2 and 15Mbps. You can manually
select settings for the H.264 profile, the GOP Structure, and the Variable Length Coding Mode
if required. However the default settings provide the optimum balance of picture quality and
bandwidth in the output transport stream for the applied input.
Encoding parameters are configured from the Encoding page on the web interface as shown
in Figure 22.

Output Resolution and Frame Rates
The scaling capabilities of the AvediaStream e3522, e3532, and e3552 encoders allow a
variety of output resolutions and frame rates, depending on the applied input signal. Lowering
the resolution to suit the output device enables you to reduce the bandwidth required in the
output stream. However, this may affect the picture quality on high resolution displays. The
Input-Output Resolution table shows the encoding output combinations (green tick marks )
and the possible combinations (grey tick marks ) for a specific input signal. All other
combinations are invalid.
Note: Progressive formats are required for scaling. A 1080i input can only be output at 1080i
or at SD.
For example, with no scaling selected the output resolution matches the input as shown in
Figure 25. If an output scaled for iPhone4 (960 x 640) is required, the table indicates an input
of 1080p or 720p is required.

Encoding – AvediaStream e3535/e3555
By applying the H.264 Scalable Video Coding (SVC) extension capabilities of the e3535, and
e3555, any input signal (up to 1080p 60Hz) can be output in a variety of resolutions and frame
rates with stream bit rates ranging between 2 and 30Mbps. (Custom bit rates can be selected
down to 100 kbps)
With the AvediaStream e3535/e3555 encoders, any output resolution and frame rate can be
selected. You can manually select settings for the H.264 profile, the GOP Structure, and the
Variable Length Coding Mode if required. However the default settings provide the optimum
balance of picture quality and bandwidth in the output transport stream for the applied input.
You can also choose MPEG-1 Layer 2 (MP2) or AAC (Advanced Audio Coding) audio ending.
The Encoding parameters are configured from the Encoding page on the web interface as
shown in Figure 27.

Output Resolution and Frame Rates
The scaling capabilities of the AvediaStream e3535 and e3555 encoders allow a variety of
output resolutions and frame rates, depending on the applied input signal. Lowering the
resolution to suit the output device enables you to reduce the bandwidth required in the output
stream. However, this may affect the picture quality on high resolution displays.
With no scaling selected the output resolution matches the input. When scaling is enabled, you
can also choose the frame rate required from the available selection.

GOP Structure
GOP (Group of Pictures) is a group of successive pictures in the video stream and is a
fundamental part of MPEG encoding. The GOP contains I, P, and B, frames. The I frame is a
reference picture, while the P and B frames contain difference information. Auto is the default
setting, producing a GOP structure of IBBP with length 15.
Closed GOP can be selected only when IBBP frame structures are selected. With closed GOP
selected, frames from the current GOP cannot reference I frames from the previous GOP.
Closed GOP MPEG streams are preferred if subsequent editing is required.

Incoming frame rate inaccurate
If “Incoming frame rate inaccurate" is displayed, the encoder has determined a difference
between the configured and the detected input frame rate. Larger differences may cause the
encoder to lose, or not achieve synchronisation. Typically this is due to a 24Hz/60Hz input
applied while a 23.98Hz/59.94Hz frame rate is configured on the web interface Input page, or
vice versa. It may also occur over DVI and RGBHV connections to PCs where standard frame
rates are not met due to graphics sub-system limitations. Check the source and encoder
settings to resolve the mismatch.
Actual Video Rate (e2532/e3530/e3532)
Displays the Actual Video Rate, which is determined by the input/source present and the
Video Bit Rate configured on the Encoding page.

The encoder uses a range of video rates, depending on the connected input/source. For
example, if the Video Bit Rate is configured to 20Mbps but an SD source is connected, the
actual video bit rate will be 10 Mbits/s. For more information refer to Encoding on page 47.
Detected Video Input (e3535)
The Detected Video Input setting is displayed. If “Incoming frame rate inaccurate" is
displayed, the encoder has determined a difference between the configured and the detected
input frame rate. Larger differences may cause the encoder to temporarily lose
synchronisation, however the encoder automatically locks to the detected signal.

Network Statistics
Viewing the network port utilisation is an easy way to check if the encoder is transmitting data
at the rate expected by the streaming settings.
To view network port utilisation, go to the Network page on the web interface. The Ethernet
interface statistics are shown at the bottom of the page. The transmit utilisation should
approximately match the rate specified on the Stream page. You would normally expect to see
very little traffic on the receive side.

APPENDIX A
Serial Interface Connection
The serial admin interface provides the ability to manage a small subset of device functionality
e.g. to configure an IP address.
Cabling
To connect to the serial interface use the DB-9 – RJ45 adaptor supplied by Exterity (shown in
Figure 44.
Figure 44 DB-9 to RJ45 serial adaptor
The female DB-9 connector should be plugged into the serial port on a PC. A straight-through
network cable should be used between the RJ45 socket on the adaptor and the admin port on
the Exterity device.
Note: Although the cable fits, the admin port should not be connected to the Ethernet port on
a PC.
Adaptor Wiring
If you do not have an adaptor you can make one using the details shown in Figure 45 and
Table 10.
