Silver Stream-In/Stream-Out at a Glance 2.0

This section provides an overview of the Silver IP Encoder (Stream-In) and the IP Decoder
(Stream-Out). It outlines how you can start using these Codecs to send audio. Section 3 con­tains more detailed information on the operation and how the Codec systems can be con­trolled by the new WEB based Management System.

2.1 Introduction

The Silver audio Codec range is based on the new APT Codec core engine. This new engine is
designed to be as flexible and versatile in use as possible. The core is powerful and address­es more than ever the needs of professional IP audio transmissions.

The set of Silver Stream-In and Stream-Out can be used to setup a full duplex link. The Sil­ver Codec range consists of the Encoder (Stream-In) and the Decoder (Stream-Out) as sepa­rate units in a ½ 1U format.

As a multi-algorithm audio Encoder or Decoder it is offering conventional analog left and
right audio connections operating through IP. These analog audio connections are carried out
for semi-professional phone jacks or as professional XLR connectors.

In the first instance the new Codec generation incorporates the enhanced versions of the
apt-X® algorithm (real time transmission on the network with data reduction by factor 4:1)
and Linear PCM 16 and 24 bit. More audio algorithms will be available optionally on coming
firmware releases.

The units are capable of delivering high quality audio used for inter-studio networking, re­mote/outside broadcasts and STL/TSL monitor applications. Enhanced apt-X® offers 16 and
24 bit operation as an improvement over the performance of the original standard 16 bit apt­x® algorithm.

Audio modes and bandwidths are dependent on the network bit rate, the algorithm, mode
and frequency response selected and the bit resolution of the desired audio. Bandwidths will
range from 3.8 to 22.5 kHz in stereo mode and 7.6 to 22.5 kHz when set for mono operation.

The Silver Codec range runs an embedded WEB GUI which can be accessed from a web
browser. It will be also fully software driven via APT's WorldCast Codec Management System
which runs on a PC connected via LAN or WAN. A headphone socket provides for additional
monitoring of the audio input or the output.

An Additional interface allows for the connection of auxiliary data terminated on a DB-9way
connector. Regardless of using the Encoder (Stream-In) or the Decoder (Stream-Out) the
AUX Data link is provided always as a duplex link (while the audio is always simplex).

The Silver Stream-In and Stream-Out come with the SureStream option applied as standard.

Both units are very similar with the exception that the Decoder offers an additional USB port
for future use (e.g. playing out stored audio files).

2.4 The WorldCast Codec Management System - Overview

The WorldCast Network Management System (NMS) allows viewing multiple units from one
control point. The program has an intuitive look and feel that is easy to understand by both
the experienced technician and the casual user.

The graphical user interface provides access to an embedded WEB GUI to the Silver IP
Streamer when accessed from the NMS family tree view. The presentation of the GUI of the
Silver units is the same when opened from the family tree view (NMS) or directly from a
WEB browser.

Figure 2-3: Family Tree of the Network Management System (NMS)

 The presentation of the Silver configuration pages is the same whether it is opened from

the family tree view (NMS) or directly from a WEB browser.

 The NextGen codec range provides a context menu by right-clicking on the device (once

it is connected). This context menu provides an option called “Open Free View” – this
option opens as many independent views of the GUI as required but only one instance in
read-write mode. All other instances are locked to read-only mode.

The Codec Management System – (continued)

The Codec Management System is designed to operate as a program under Windows as a
single task. This means that only one instance of the NMS software can be installed on the
same PC.

Nevertheless, it’s possible and allowed to have more than one installation of the NMS in the
network. The NMS software design does not allow a simultaneous access to the same Codec
device from different seats. If one seat has opened a Codec device on the family tree, the
software inhibits any attempt of accessing the same unit from another seat in read/write
mode. The first user gets the read-write control of this particular device, and any other user
will be prompted to be restricted on read-only permissions. This feature avoids configuration
conflicts caused by several seats.

Whenever a user opens a device on the family tree, the NMS sends out a broadcast re­quest/announcement to the network looking for any other user actually configuring this par­ticular unit.

If the network does not allow broadcasting, i.e. in public domain networks like the internet,
this protection becomes ineffective.

2.6 Getting Started

Before you can launch the Management System please ensure the following pre-conditions of
your network settings:

 To get started with the NMS application, ensure that the cabling is properly connected

from the Codec to the PC, and that your service PC’s Ethernet cards has an IP address
within the range of 192.168.100.0 to 192.168.100.255. The Silver Stream-In and
Stream-Out are set to an IP address within this range as a factory default – usually

192.168.100.110.

 The NMS application will remain inactive until a link is established between the service

PC and an active Codec device.

Release Notes

As of this publication date, system release 1.0.4 is shipped with the Codec device. We rec­ommend that you check the APT website for updates.

2.7 Along the Main Tool Bar

Figure 2-5: NMS Tool Bar – functional overview

The tools and controls on the Main Tool Bar are mainly used for higher level operations and
management rather than controlling a dedicated audio Codec. Connected audio devices are
configured and managed with an individual set of controls depending of the Codec type.

 Depending on the connected Codec devices, not all of the tool bar functions are relevant

for the particular codec; some features are not supported at all or not yet supported by
different Codes.

2.7.1 Connecting a Codec to the Family Tree

The NMS allows adding Codecs to and removing Codecs from the Family Tree.

The Main Screen will appear without any Codec attached to the Family Tree for the first time.
The first option provides a quick way to attach a Codec with a known IP address to the NMS.
Clicking on “Add Unit” opens the “Add New Unit” window. Enter the IP address of the Codec

that you wish to connect and click “Add”. This window also provides access to the Net Wizard
and offers some options of the unit types; the “AutoDetect” radio button is selected as de-

fault and automatically chose the correct type of Codec.

Connecting a Codec to the Family Tree (continued)

Add a new Codec by
known IP address

Figure 2-6: Shows how to
add a Codec with a known
IP address to the Main
Screen

If you opt for “AutoDetect” (Radio Button) and the NMS is not able to connect to the desired

Codec then you will receive the following messages:

Message: Warning

Figure 2-7: If adding a Co­dec by known IP address

with “AutoDetect” selected

fails, you will receive this
warning

Message: Warning

Figure 2-8: If adding a Co­dec by known IP address

with “unit type” selected

fails again, you will receive
this message

If you still wish to use the chosen IP address click on “Yes”. The NMS will show this unit as
unreachable on the Main Page (refer to the screen shots on the next pages).

2.7.2 Deleting a Codec device from the Main Screen

The second button on the Tool Bar is for deleting a Codec from the main screen. Select the

2.7.3 The Net Wizard

The third button starts the Net Wizard, which scans a user defined IP address range in order
to auto-detect any reachable WorldNet/WorldCast Codecs on the network. Click on “Net Wiz­ard” to start the network scan. Run the Net Wizard for the auto-detection of any Codec on
the network.

The Net Wizard provides automatic detection of each device connected to the network by its
corresponding IP address. The Net Wizard scans an IP address range and reports the detect­ed unit. You may choose whether to add all or a selection of the detected frames to the Main
Screen. Click on “Net Wizard” and follow the Wizard’s instructions.

Figure 2-9: Shows results from a network scan of range IP: 192.168.115.1 onwards. The scan was
stopped manually at xxx.xxx.xxx.116 (no further units expected).

Begin by entering an IP address you wish to start searching from; then click on “Begin
Scan”. The Net Wizard will scan all IP addresses from the one entered, ending when the last

number in the search address reaches 255. You can stop the search at any stage by clicking
on “Stop Scan”.

Whenever the Net Wizard finds Codec devices it will display them in a list on the right hand
side of the screen.

To add a unit to the family tree, double click on the chosen entry in the list or to add all of
them click on “Add All”.

If the Net Wizard has not found any connected units, you should double check the network
settings on the Net Wizard. The Wizard scans the IP address range from the IP address you
enter incrementing the last number until it reaches 255.

The Net Wizard (continued)

For the PC to be able to address the audio Codecs, its IP address must be in the same subnet
as the Codecs. If you are using the DHCP service for dynamic assigned IP addresses on your
PC check that the assigned address is in the same subnet as the Codecs. If not then you
must disable DHCP and assign an IP address manually which is in the correct range.

 Once the audio Codec has successfully connected to the NMS application, you can also

change the unit’s IP address to the required value of your network using the NMS.

 You must first establish the network connection in order to access the Codec’s configu-

ration menus.

Figure 2-10: This example shows one WorldNet Oslo frame and one Horizon NextGen Codec successfully
added to the Family Tree.

Note: The IP address of the frame as well as the serial number and name of the frame (if
configured) are displayed. If the NMS cannot connect to a particular Codec it will show the
serial number as unreachable (disconnected) and add the flashing “ ” graphic.

2.7.4 Reset the Codec Hardware IP Address

In the case that you cannot detect the required Codec device on your network, neither by
entering the IP address manually or by running the Net Wizard, you should reset the unit in
order to force the hardware default IP address. This is done by pressing the reset button on
the hardware front panel. Refer to section 3.1.2.3 of this manual about how to initiate the
reset. After you have reset the Codec and the Net Wizard has successfully connected it to the
NMS, you can then set the IP address to the required value of your network.

The Silver Stream-In/Stream-Out hardware default IP address: 192.168.100.110

2.7.5 Current Alarms

Clicking on the “Current Alarms” button opens a separate window showing the currently

flagged alarms of all connected codec frames. This alarm window presents the alarms status
in real time.

2.7.6 The NMS User Management

Clicking on the “Users” button opens the User Management Window which provides the op­tion of adding new users or deleting existing user accounts for the NMS (not for a particular
Codec).

 It is important to know that all NextGen Codec Devices (Silver Codecs, Horizon, IP De-

coder etc.) are currently supported by an embedded WEB browser window on the NMS
application. This has effect on several NMS functions and to the NMS user management
in particular.

To add a new user select “Add new user.” Enter the new user details in the dialog box pro­vided. Decide which type of access this new user should have, and select the appropriate us­er level. Select “Save Changes” to add the new user to the account list.

To remove an account, highlight the user account on the list of available users and select
“Remove existing user.” Selecting “Save changes” stores all changes and closes the Users
dialog window.

If you want to modify an already existing account, you must first delete this account and
then add it again with your modifications.

The NMS User Management (continued)

 All NextGen Codec devices have their own user management on the embedded WEB

GUI. The NMS access limitation has effect on the NMS controls and the WorldNet Oslo
frames only! In consequence a NMS Guest account may have the full access to a Silver
Codec if logged in as Silver Codec Administrator.

NMS - Administrator:

Administrator allows full access to all features and controls of the Management System.
This includes the full control of WorldNet Oslo frames.

NMS - Normal:

Allows viewing access to the settings and logs and allows you to set up and clear down
IP connections (on the WorldNet Oslo frames).

NMS - Read Only:

This is very limited “Read Only” access that allows reading active connections only. Log­ging into a NextGen Codec is managed by the WEG GUI user management system.

These options are not relevant for the Silver Codecs.

Use NAT Traversal Mode

NAT Traversal Mode is required if the service PC running the NMS is sitting behind a NAT
traversal router. Checking this box forces the NMS communication to use the same IP
ports for sending and receiving packets through the router (Tx port = Rx port). In almost
all cased the NAT traversal router allows receiving traffic that is assigned to the same IP
port as the outgoing IP packets.

2.7.10 Firmware Update Manager

Clicking on the “NMS Firmware Update Manager” button allows you to manage the firmware
update of one or more Codec units in a centralized way. The Firmware Update Manager is
comparing the firmware currently installed in each Codec device of the Tree view to the
firmware package that you have selected for the update. The following description shows the
procedure on a Horizon NextGen, but it is the same for all APT Codecs.

Clicking on the Firmware Update Manager button opens the following window:

Figure 2-15: Shows the Firmware Update Manager Window (this example shows a Horizon NextGen)

The Firmware Update Manger detects all currently connected units from the NMS family tree.
Clicking on an individual unit selects it and allows removing it from the list (by clicking on

“Remove”). “Add” a unit opens an entry field for entering an IP address of non-detected de-
vices. “Import” and “Export” allows loading or saving the list of Codecs for firmware updat-

ing.

 Each type of Codec has its own firmware file container (the .osr file) clearly labeled, e.g.

SLVR_SR_xxx for Silver Stream-In/Stream-Out. The firmware Update Manager process­es one firmware container at once; hence all Codecs that are not from the selected type
should be removed from the list (e.g., Oslo frames and Horizon NextGen or IP-Decoder).

Tel.: [phone] | Fax: [phone] | www.aptcodecs.com | [e-mail]

Firmware Update Procedure

After the Update Manager has detected the all Codecs, the list must be cleared as described
above; only the Silver Codecs should be listed. Before the update procedure can start, the
firmware file container must be selected.

Figure 2-16: Shows the file manager for selecting the desired .osr container (this example shows a Hori­zon NextGen)

Clicking on the file manger icon opens the file manager and allows navigating to the location
on the hard drive where the firmware was stored.

Once the firmware was selected, press “Next” to start the firmware scanning.

Tel.: [phone] | Fax: [phone] | www.aptcodecs.com | [e-mail]

Firmware Update Procedure (continued)

The firmware Update Manager scans each selected unit and analyses the currently running
firmware; it compares these system release versions with the firmware container that was
selected for the update and presents the results:

Figure 2-18: Presents the firmware scanning results (this example shows a Horizon NextGen)

The figure above shows the unit type, the current version of firmware and the new version.
In this example both, the current and the new version are the same. The blue arrow on the
“Action” row indicates that an update is not necessary. However, you may make different op­tions by selecting a card and clicking on one of the following buttons:

“Skip” leaves the firmware unchanged for the selected unit. In case that the firmware
scan result shows the green update arrow clicking on “Skip” will inhibit an update.

“Update” forces the update to the version contained in the .osr file for the selected unit,

regardless of the scan result. The Firmware Update Manager will ask for your confirma­tion in case you attempt to downgrade a Codec (current release is newer than the re­lease contained in the .osr file).

Clicking on this “Update” button starts the update process. The firmware will be loaded

to the Codec unit(s) simultaneously. The Update Manager will process and monitor the
updates. The process always starts first by uploading all necessary firmware to each Co-

dec concerned. This operation is reported as “Upload” in the Action column (see image

on next page).

2.8 Codecs and Switches

Codecs react in a similar way to all network devices and therefore should not be flooded with
background non-related network traffic.

The best way to limit traffic is to have a switch (not a hub, or a switch that acts like a hub)
communicating with the unit similar to the diagram below.

Figure 2-22: This figure shows the recommended network installation: Audio Codec connected to a
Switch

It is recommended that the port settings on the switch are set to auto negotiate.

 Default IP address for the ETH: 192.168.100.110 – DHCP disabled on default.

WorldCast/Silver WEB-Browser GUI 4.0

The WorldCast/Silver Web GUI is the control and monitoring tool which communicates with
the Silver units. All the next generation units, including the Silver range, run their own Web­server with can connect to standard Web Browsers or to the APT NMS. It is used to configure
the unit, create audio streams and to get status and alarm information.

This section outlines this application and provides a detailed description of all aspects of the
Silver configuration options.

4.1 The WorldCast WEB GUI - Overview

The Silver Web GUI allows you to view and control a single instance of the Silver IP­Streamer. The application has an intuitive look and feel that is easy to understand by both
the experienced technician and the casual user. All configuration instructions described in
this section relate to the WEB GUI. This section provides detailed step-by-step instructions
on how to set up the Silver Stream-In/Stream-Out.

4.1.1 WEB GUI – Technical Requirements

The Web GUI can be run from a standard web browser such as:

 Mozilla Firefox (from v. 6.0)
 Internet Explorer (from IE7, IE8)
 Google Chrome
 Safari

 Recommended screen/window size: min. 1280px by 1024px

The GUI is based on a web application using inherent browser technologies only: Java Script,
Cookies and CSS (2.0). The application does not require installing any additional browser
Add-In. The Cookies are session Cookies and used as temporary memory for configuration
changes until they are uploaded to the hardware. A session Cookie expires after the actual
session was closed.

4.1.2 Default Network Settings

The Silver units provide a single IP interface for IP audio streaming and web browser control.

The default settings for accessing the web server are (port #80):

4.3 WEB GUI – Home Page

Once the Web GUI has downloaded the application data from the Codec it will show the Sta­tus Page of the WEB application. The Status Page consists of three sections: The main menu
(1) on the left hand side, the main pages (2) in the middle and the “Current Status” frame
(3) on the right hand side which can be hidden and indicated by a colored bar (green, yellow
or red in dependence of current alarm events).

Figure 4-3: Shows the Unit Status page of a Stream-In unit with popped up "Current Status" frame

The default Main Page (2) is always the Unit Status page summarizing the status of the
hardware unit, the current Audio Codec settings and the Connection Status. The color of the
stylized LEDs indicates the current status condition (either green or red).

4.3.1 WEB GUI Session Close – Session Time Out

The WEB GUI allows connecting to a Silver unit in read/write mode only on one instance at
once. While in “Read Only” mode many instances can monitor a single Codec simultaneously.
Each time the browser connects to the hardware in read/write mode (Admin account) a new
session will be opened. This session must be closed after a period of time in order to allow
another seat connecting to the Codec in read/write mode. A timer ensures that a session
cannot keep open accidently and closes the session after 60 minutes automatically, if no ac­tion takes place in this period of time.

A session can be closed manually by using the “Logout” button, closing the browser or the
browser tab or by forcing a reloading of the application data by pressing the F5 key.

If the session has timed out or the session has been closed manually, a red “Session Locked”
icon appears on the top right corner of the browser window.

Unit Status Section

1. Unit Temperature

This shows the current Engine temperature of the unit and is not the environmental tem­perature. This value can exceed 40°C without causing a critical situation. There are no
fans fitted as default for two reasons; the emitted noise, and fans are wear and tear
items which need to be replaced periodically.

2. IP Transport Error

This error indication is related to IP data stream. If a stream is enabled on the streams
table it broadcasts any IP error to this alarm indication.

Main Menu – Status/Alarms Page (continued)

Audio Alarms Section

This section shows the status of the audio alarms. The alarms indicated in this section
are Silence Detections for Left and Right Input (Stream-In) or Output (Stream-Out) and
Sync alarm (on Stream-Out only).

1. Audio Alarms (Silence Detection)

The Audio signal has decreased below the threshold and timeout specified in the audio
configuration menu. This alarm will be flagged if silence occurs on the inputs (Stream-In)
or on the outputs (Stream-Out) for any reason.

2. Sync Failure (AutoSync Alarm) – Stream-Out only

This Alarm indicates a general sync failure in situation where an excessive amount of
packets were dropped or out-of-sequence that results in a gap to the audio stream sig­nificant enough to generate the Sync alarm. The different audio algorithms or linear PCM
have their specific sync-failure sensitivity.

For Enhanced apt-X this alarm corresponds to the AutoSync Alarm. AutoSync is a bit pat­tern sent embedded in the Enhanced apt-X audio stream that allows a very rapid re­sumption of decoding after a gap in the bit stream. This alarm will be flagged if the fol­lowing conditions occur (for network faults, usually along with other network specific
alarms too):

- Mismatch of audio algorithms on Transmit and Receive units

- Connection or transport errors

- A Call being dropped by the Transmit unit

Transport Alarms

This section covers IP alarms only such as IP Rx or Tx errors and audio mismatch.

1. IP Tx Error – Stream-In

The packets from the Tx unit have not been confirmed as hitting the Rx unit – either the
Rx unit is stating in its RTCP stream that there has been no packets, the RTCP port has
been blocked, or there is another form of network fault resulting in no line of sight to the
Rx codec.

2. IP Rx Error – Stream-Out

Packets are not arriving to the Decoder, and it is expecting to see traffic. This can be
caused by stream being dropped on the Encoder, a network fault or mismatch in audio
algorithm settings.

3. Audio Mismatch

This is likely to be raised if the algorithm does not match on both sides of the link.

Connection Alarm (ETH)

Physical loss of connection to network directly (lead pulled)

4.4.4.1 About Stream Tables (general)

In general, a Stream Table (1) is a list of IP-Stream configurations organized in a table. In
dependence on where a stream table is accessed it will appear as red-only table, like on the
performance monitor page, or the table can be directly accessed for changing values and en­tries.

Figure 4-10: Shows Stream Tables from the Encoder and the Decoder

The exposure options of the Stream Table are flexible and can be widely controlled by the
user. Clicking on the little arrow on each of the columns (on mouse over) opens a context
menu and allows sorting the table ascending or descending. Another submenu provides tick
boxes for controlling the columns visibility. In general the stream table exposure also de­pends on the size of the current browser window. The width of the columns can be adjusted
by clicking between the columns and drag the border as appropriated.

4.4.5 Main Menu – Connection/Connection Page

The “Connection Page” is the page where IP streams and connections must be created and
can be managed. Basically a “Connection” consists of two parts, the audio settings and the IP

configuration.

The table in the middle of this page shows the currently applied Audio setting on the Encoder
(Stream-In) or the Decoder (Stream-Out).

Figure 4-12: Shows the Connection Page of the Stream-In unit

The Silver WEB GUI offers three ways to create and apply a configuration.

2. Quick Connection (applying a profile to the unit)

3. Connection Wizard (a step-by-step guide)

4. Advanced Configuration (direct editing of stream table and audio mode settings)

Main Menu – Connection/Connection Page (continued)

Quick Connection (1)

A “Quick Connection” is basically a pre-configured and previously stored profile. This pro­file was created and merged from an audio mode configuration and an IP stream setup.
Before a Quick Connection can be used, a profile must have been created first.

Clicking on the little arrow opens a list with available profiles. Once the required profile

was selected it can be applied seamlessly to the Codec by clicking the “Apply” button on

the bottom right corner.

Configuration Wizard (2)

The “Configuration Wizard” guides to a step-by-step procedure creating a profile. It
prompts for audio settings and for IP settings. Finally it creates a profile by merging both
components. Once a profile was created it appears on the Quick Connection drop down
list.

Advanced Configuration (3)

The “Advanced” configuration procedure provides all configuration and management op­tions on a single page. Other than the Configuration Wizard the “Advanced” configuration
allows modifications on the currently applied profile and configuration. It also provides
options and tools to edit already created profiles.

4.4.5.1 Connection Wizard - Creating a Profile

Connection Wizard – Profile Name

Selecting the radio box “Connection Wizard” on the connection page starts the Wizard. Firstly

a profile name must be entered in the Name field. Once a name is entered the “Next” button
becomes active. Clicking on this button opens the next page prompting the audio Codec set­tings.

4.4.5.2 Connection Wizard – Codec Settings

The next page guides to the Audio mode settings. The Silver units provide similar pages for
the Encoder and the Decoder depending on the type of unit, hence the Encoder configuration
is provided on the Stream-In unit and the Decoder configuration on the Stream-Out.

Figure 4-14: Shows the Decoder configuration page (Stream-Out)

Algorithm (1)

Clicking on the “Algorithm” field opens the drop down list offering the available audio co­dec formats. Currently Enhanced apt-X and Linear PCM are available. Select the desired
format then click on the “Bit Rate” field.

Bit Rate (2)

Corresponding to the chosen audio format this drop down list presents the available bit
rates. After selecting the bit rate, the “Mode” field entry may be filled automatically in
dependence of the audio mode and chosen bit rate.

Audio Mode (3)

Audio Mode means either Mono or Stereo. If this field is not computed automatically,
chose the desired mode. Finally the “Bandwidth” field displays the resulting audio band­width and the sample frequency.

 The Encoder and Decoder configuration is almost identical. There is one important check

box on the Decoder page: The Re-Sequencer check box – keep this enabled! This en­sures that packets arriving out of order can be re-ordered inside the de-jitter buffer.

After completing the Encoder/Decoder settings also, click on the “Next” button to enter the

IP Stream configuration page.

SureStream 5.0

SureStream Technology is a standard feature of the Silver IP Streamer range.

Figure 5-1: Shows the Status Page with SureStream enabled

5.1 About SureStream

SureStream Technology is a revolutionary innovation from APT that enables broadcasters to
use inexpensive IP links and still maintain professional broadcast-grade audio quality and re­liability. It delivers the audio quality and reliability known from a synchronized TDM based
link at a fraction of the associated cost.

The technology approach of SureStream is based on redundant streaming. SureStream repli­cates a single program audio stream and passes it through the Statistical Diversity Genera­tor. Following this process the redundant program streams appear on the network as unique
streams generated from different or the same source.

In practice a single stream will be duplicated on the IP port as SureStream component
streams. This feature works on a single physical port (like on the Silver Streamer Range) as
well as on Codec systems equipped with dual IP ports.

SureStream is highly efficient on potentially lossy networks like the public Internet. It can al­so be used for permanent redundant streaming on managed networks.

About SureStream (continued)

Figure 5-2: Shows a typical configuration running SureStream on a single IP port

The configuration example above shows a typical SureStream configuration using two
SureStream component streams. This example uses the Internet with standard xDSL access
services. Diverse streaming on the internet has the effect, that the access routers treat each
SureStream component stream individually by passing it randomly on different paths to the
destination IP address.

On the receiving end, the Enhanced Re-Sequencer generates from all component streams
the single packet stream on a first-in-first-out packet basis. All duplicated/redundant packets
will be dropped. The number of component streams is not limited by the SureStream tech­nology.

SureStream is a powerful algorithm that protects an IP link against packet losses and Loss of
Connection errors. The latter protection can be achieved only if the Codec device uses dual
IP ports for streaming out the component streams.

 On a single IP port device, like the Stream-In and Stream-Out, SureStream cannot pro-

tect the IP link against Loss of Connection errors.

About SureStream (continued)

5.1.1 SureStream Encoder

On the Encoder side the heart of SureStream is the Statistical Diversity Generator. This gen­erator ensures that the component streams appear on the network as diverse as possible.
This generator runs an algorithm that can be set up with three different sets of parameters
(called “levels”) allowing the use of more than one component stream while keeping each
stream divers from each other.

5.1.2 SureStream Decoder

Once SureStream has generated duplicated streams with the same payload intended to
reach the same receiver, the Decoder on the receiving end must cope with a massive
amount of redundant packets arriving from a single or different networks. Allowing the De­coder to cope with duplicated packets it must run the complementary algorithm as on the
Encoder side; this is the Enhanced Packet Re-Sequencer Engine.

5.2 SureStream – Encoder Configuration

Creating a SureStream component stream follows basically the same procedure as a normal
stream configuration. A set of component streams will be identified as part of a SureStream
group by the equal packet size. This is an important indication, because within a set of re­dundant streams the packet sizes must be equal. If a set of component streams are config­ured correctly, the connection page will indicate this by grouping the corresponding streams
(SureStream group). If the packet size is not equal on all component streams, the streams
will be treated separately and no SureStream group will be generated.

Figure 5-3: Shows a SureStream configuration on the Encoder

 A SureStream group (i.e. SureStream 1) will be displayed only if the packet sizes on ALL

component streams are equal!

The figure above shows a working Encoder configuration in principal with two streams are
assigned to the same destination IP address, hence they are received on a single port at the
Decoder end. This implies that both streams are going out on the same ETH port on the En­coder into a single network. – In a real world application this configuration will protect the IP
link against packet losses very efficiently as explained above.

The next section outlines the recommended and mandatory settings for a group of compo­nent streams.

SureStream – Encoder Configuration (continued)

Once the SureStream license was applied to the unit the Diversity Generator option appear
on the stream configuration window. Again, creating a group of component streams follows
the normal procedure.

Figure 5-4: Shows the Diversity Generator options on the stream configuration window

5.2.1 About Diversity Generator Levels

The SureStream Diversity Generator can be either disabled or set from “Level I” to “Level
III”. A “Level” does not indicate the level of severity of SureStream. A “Level” is a set of pa-
rameters used by the Diversity Generator to ensure the stream diversity. All three “Levels”

work on the same level of severity but differently from each other.

Having three sets of parameters allows to configuring more than one redundant stream and
keeping all streams processed individually by the Diversity Generator. It has been seen
sometimes that a particular “Level” delivers better results than another.

Therefore it is worthwhile to trying out what Level delivers the best results in a particular
network environment.

 Whenever a set of SureStream component streams are created, one of them should

have the Diversity Generator Level set to off. All other component streams should run
on a different level (I-III).

5.2.2 Creating a Set of Component Streams

A set of component streams processed by the Diversity Generator is not limited to a particu­lar number of streams. In practice a set of two component streams works reliably. However,
the Silver Streamer allows to creating more than one redundant stream.

5.3 SureStream – Decoder Configuration

Configuring the Decoder for using SureStream follows the normal procedure for creating as
many as desired receive streams (component streams).

A SureStream group will be displayed only if the RX Latency settings are equal on all compo­nent streams of a group. This is a very important setting and must not be ignored!

On the Decoder section, the Re-Sequencer as the complementary part of the Diversity Gen­erator MUST be enabled!

Figure 5-5: Shows a SureStream configuration on the Decoder with two streams received

The figure above shows a working Decoder configuration in principal. Again, two component
streams are received on the same ETH port; hence they are transmitted on a single port at
the Encoder end (as shown in the Encoder section).

 On the Decoder, SureStream needs the Re-Sequencer to be enabled whenever more

than one stream must be received from the same Encoder, regardless of the Diversity
Generator level settings of the Encoder!

 The RX Latency setting must be equal on each component stream of a SureStream

group!

5.3.1 SureStream – Decoder Performance

The performance monitor delivers precise information about the component streams treated
by SureStream and the summary performance of the SureStream group.

Figure 5-7: Shows the stream performance of component streams and the SureStream group

The figure above shows a perfectly working SureStream configuration on a Decoder. The
SureStream group consists of two component streams (Rx1/Rx2). While Rx1 shows no
Dropped Packets, no Duplicated Packets and no LOC errors, the Rx2 shows a huge amount of
duplicated packets. This is exactly how the Enhanced Re-Sequencer works. It re-combines
the component streams and creates an error-free packet streams for decoding and discards
all redundant packets.

In a real world environment, the component streams will show lost packets errors.

The statistic below the SureStream group shows the performance of the re-combined
stream. If any error (dropped packets) appears on this line, the decoder will be affected and
artifacts may be audible. In this case it is worthwhile trying to use another Diversity Layer on
the Encoder or, if possible, adding another component stream to the SureStream group.

This is a straight forward and intuitive procedure.

 A firmware update can be processed on the Admin Account only

6.1 About – System Firmware

A Firmware release consists of a set of inter-compatible firmware files. These are system files
for the DSP, the system operational system and the WEB GUI. A system release will be de­livered always as a Zip-Archive.

 The firmware zip- archive must never be unzipped on a PC. The system upload proce-

dure requests this zipped archive.

6.1.1 Firmware Update – Step 1

Open the “Update Page” on the main menu (System – Update). The following screen will be

presented:

6.1.5 Firmware Update – Step 5

The firmware update is a completely hidden process in order to avoid any user interaction.
Once you have clicked the “Upload” button the system prompts you to confirm the process.
This is the only user action necessary after initializing the update procedure!

- After approximately 20 seconds the browser shows the LogIn page

- The LogIn page is inactive for another 4 minutes

- 4 ½ minutes after initializing the upload process, the unit will allow to log in again.

This is the point in time the unit continues to operate in the same way as previously.

Figure 6-5: This browser switches to the LogIn page after approximately 20 seconds.

It is not necessary to re-start the unit after the update process. All settings will appear as
configured. On a live-link, the stream will be re-established automatically. No user action is
necessary to re-connect a running system.
