Installation
Connecting the Cisco Digital Media Encoder 2200
Although it has many features and capabilities, the encoder at its most basic function takes analog audio
and video input and processes the signals and then encodes them into digital IP video formats. Then, the
encoder delivers the IP audio and video content to a storage device or streams it over an IP network.
There are four requirements for setting up the encoder for streaming or capturing video, as follows:
• AC power source (100-240v)
• Audio/Video source (camera, video player, or other A/V output device)
• IP network and/or Internet connection
• A streaming media server for streaming your content to many viewers
Connecting to an Electrical Power Source
The appropriate power cable is specified when your unit is ordered. Attach the block end to the power
input located on the upper corner on the rear panel of the encoder (
Plug the other end into a wall outlet or surge protection enabled power strip that is connected to wall
outlet or other common power source.

What is Streaming Media?
Streaming media is media that is consumed (read, heard, viewed) while it is being delivered. Streaming
is more a property of the delivery system than the media itself. The distinction is usually applied to media
that is distributed over computer networks; most other delivery systems are either inherently streaming
(radio, television, Internet TV) or inherently non-streaming (books, video cassettes, audio CDs).
Cisco Digital Media Encoder 2200 is designed specifically for streaming audio and video media over an
IP network.

Introduction
Streaming Infrastructure
Before setting up your new Cisco Digital Media Encoder 2200, it is useful to understand the complete
overview of live streaming video—from video capture to streaming video playback.
There are many applications for capturing video into the computer environment that can range from
DVD authoring to live webcasting. Regardless of the final use of the video, all can be categorized into
three main workflow processes:
• Single video/session capture (one-off file capture for non-real time delivery)
–
Typically the captured file is then processed and/or authored into its final form for delivery
• Batch video/session capture (archiving, scheduling and storage)
–
Multiple source content is to be digitalized
–
Device control is needed for unattended source
–
Ability to schedule sessions is needed to capture timed events
• Live video capture, processing and delivery (webcasting)
–
Can be single or multiple sources

Introduction
Tutorial
In choosing the right streaming format for your needs, you should first consider the audience to which
you will be sending your content. What is the most common player that they will have available to watch
your content? This will determine the format of the stream that you will create for your audience.
To determine the data rate that you will stream your content, you will need to determine the IP bandwidth
to which your audience has access. For example, if the access method uses an ISDN connection or less,
then you would stream your video and/or audio at a low data rate such as QCIF at 56kbps. If the access
is much greater like a cable modem or DSL connection, then you can provide a higher quality stream at
full resolution at 2 Mbps.
Cisco Digital Media Encoder 2200 provides preconfigured encoding profiles for different bandwidth
connections. The profiles loaded will depend upon how you configure your encoder on its initial startup.
There are two interfaces for operation of your Cisco Digital Media Encoder 2200: the encoder front
panel LCD display and buttons and the Niagara SCX Web Interface. This tutorial is divided into the
following two parts:
1. Basic Operation: Using the Front Panel, page 2-4
2. Advanced Operation: Using the Niagara SCX Web Interface, page 2-15
Note To access the Niagara SCX Web Interface or the Niagara SCX Encoder Explorer Software, you will
need a computer with a current web browser installed that has an IP connection to the encoder via a local
network on which both the encoder and the computer reside or through a direct IP connection by using
the included RJ-45 cable to connect directly from the encoder to a computer.

Basic Operation: Using the Front Panel
Starting an Encoding Session
The encoder LCD readout will display a list of available encoder profiles that can be used together with
the current status of each.
Note The name of each encoder profile is abbreviated to display the first 10 characters. When creating names
for custom profiles, be sure to create unique names that will be distinguishable by the first ten characters.
Use the <UP> and <DOWN> buttons to move the select arrow to point to the encoder profile that you
want the encoder to use for this encoding session.
Once you select the encoder profile you need, press the <STREAM> button again to start the encoder.
Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200
The encoder LCD readout then displays messages about the encoder start process.
After the encoder session has successfully begun, the encoder LCD readout returns to the previous
display of available encoders. The screen will indicate that the encoder profile you selected has begun
encoding.
If the encoder you started was assigned to one of the EZStream ABC buttons, the corresponding button
flashes and steady illuminates during and after the starting process.
By repeating this method, you can quickly start multiple encoders at the same time.
Cisco Digital Media Encoder 2200 is a two-channel encoder, which means you can connect and stream
up to two audio and video sources at any given time. However, you can stream the same audio and video
at multiple data rates and multiple formats to provide the best user experience for different viewing
audiences.
2-6
For example, you can stream Windows Media at full resolution at 1 Mbps and the same time stream
RealVideo at CIF resolution at 300kbps.

Basic Operation: Using the Front Panel
Warning
There are limitations to the number of streams that you can capture simultaneously. If you attempt to
capture more streams than the encoder is capable of processing simultaneously, the streams will
drop frames and the video will appear to stutter resulting in a poor viewer experience. If the number
of sessions is not reduced in order to reduce CPU load, all encoding sessions could self-terminate
without warning.
Checking CPU Usage
Since you are able to start multiple streams, understanding how much of the processing power of the
encoder is being used is invaluable. If you are using less than 50%, then you should be able to start
another encoding session without adversely affecting system performance.
Press the <MENU> button to display the main menu on the encoder LCD readout.
The LCD readout will display the following menu choices:
Using the <UP> and <DOWN> buttons, move the arrow until it is next to the menu item Access and then
press the <ENTER> button.
OL-17938-01
The LCD readout will display the Access menu choices. Press the <ENTER> button with CPU menu
item selected.
The encoder LCD readout displays the amount of CPU cycles in use. When the encoder is idle (no
encoder sessions running), the CPU percent displayed should be 4% or less. If one or more encoder
sessions are running, then the percent displayed will be much higher and will fluctuate in a range of +/10 percentage points.
Press the <ENTER> button to return to the previous menu.

Basic Operation: Using the Front Panel
Stopping an Encoding Session
To stop an encoder, press the <STOP> button.
The encoder LCD readout displays the list of encoding and shows the current status of each session.
Using the <UP> and <DOWN> buttons, move the pointer to the position next to the encoding session
you want to terminate.
Press the <STOP> button again, and the encoder session selected will terminate.
Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200
To return to the main menu, press the <MENU> button.
Connecting an External Storage Device
The Cisco Digital Media Encoder 2200 rear panel provides two USB ports, and the front panel provides
one. You can connect almost any standard USB flash drive to one or both of these ports. This allows you
to export any AV files you may have created on the encoder’s local storage drive. The local storage drive
is the D drive when you use the Save to File setting while you employ the Niagara SCX Web Interface.
When you insert a USB flash drive in one of the USB ports on the Cisco Digital Media Encoder 2200,
the encoder automatically detects the removable storage device and assigns a random drive letter to the
device. This device can capture files directly or can be employed to use the encoder Export File
function, which is available for access when using the front panel menu.
Exporting Captured Video Files
You can export your captured video files to an external USB drive.

OL-17938-01
Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200
Note To export files to a USB device from Cisco Digital Media Encoder 2200, you must set a default location
for the captured video files via the SCX Web Interface, and place those files in that default location. This
can be done on the System Configuration page of the web interface at the *Default AV Folder box. By
default, this folder is set to D:\AVFiles. After you input the preferred default location in the *Default AV
Folder box, you can begin exporting your files from the encoder.
Press the <Menu> button to access the encoder menu.
Using the <UP> and <DOWN> arrow buttons, highlight the Export Files option, and press the <Enter>
button.

DME Security Best Practices
We wrote topics in this section to answer and expand upon these customer questions about
DME
security:
• CSCsz67661 — How do I change the factory-default password for Windows?
• CSCta04924 — How do I disable unneeded Windows services, such as NNTP, SMTP, and SNMP?
• CSCsz67661 — How do I safeguard my encoded files on the DME file share?
Warning
Factory-defined passwords exist by default on all new and newly restored DMEs. These credentials
persist until you change them. Because they are well-known, these credentials are a security
vulnerability in your network. Therefore, we recommend very strongly that you change
each time that you start to configure a DME.
In addition, some services are enabled by default that you might never use. We recommend that you
disable all unneeded services.

Warning
Never configure a DME to log in automatically. Doing so
prevents true security in your network.
If — despite our recommendation — you configure a DME to log into
Windows automatically, password management becomes far more
complex. Thus, any time that you neglect to change an auto-logon
password specifically, you will prevent your DME from working as
designed. See
Other Required Password Maintenance (Only When
Autologon Is Configured), page 2-13.

Be very careful as you complete this workflow. Any mistakes that you make might prevent your DME
from booting correctly or functioning correctly.
Before You Begin
• This workflow uses the instance of Microsoft Windows that runs on your DME. Even though a
remote management connection might be sufficient, we recommend instead that you connect a
keyboard, a mouse, and a monitor to your DME directly and use them to control Windows.
• From Step 1, this workflow assumes that your DME is either new or in a factory-restored condition.
If this is not true, or if you are not sure, we recommend very strongly that you perform a factory
restore operation now.
