There are two parts to the complete installation of the encoder, as follows:

1.

2.

Connecting the Cisco Digital Media Encoder 2200

Configuring the Cisco Digital Media Encoder 2200

Most of the basic operations you will routinely use are performed from the front panel of the encoder, shown in

Figure 1-2 .

There are advanced setup and operations you may wish to access and to do so you will need to access the SCX Web Interface from a computer that resides on the same network as the encoder.

Although these advanced operations are not required for most streaming applications, you may want to customize your encoding settings and assign specific encoding profiles to the EZStream® ABC buttons on the front panel. The SCX Web Interface provides the ability to remote control your encoder from a computer that could be rooms or continents away from the system provided that both your encoder and the computer have Internet access to communicate with each other.

First, you need to connect the encoder. See the

“Connecting the Cisco Digital Media Encoder 2200”

section for connection information.

Chapter 1 Installing the Cisco Digital Media Encoder 2200

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 (

Figure 1-1 ).

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.

Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Note If you are not familiar with network protocols, please contact your network administrator for assistance.

The Cisco Digital Media Encoder 2200 network settings for its two 1,000 megabit network interfaces default to dynamically obtain an IP address from a DHCP server on the network.

If a DHCP server is not available or cannot be found on the network, then the encoder will assign its own

IP address.

For most network environments, it will not be necessary to modify these default settings. However, if you wish to assign a static IP address to the encoder’s Network Interface Cards (NICs), then you can change the network setting using the encoder front panel menu.

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

Live event at a specific time

Can be a remote or local capture

– Final content is delivered in real time to viewers

Each category has its unique set of requirements that also dictates different user interfaces, functionality and experiences. The Cisco Digital Media Encoder 2200 is designed for live video capture, processing and delivery.

Introduction

Simple Guide to Streaming Audio and Video Types

Cisco Digital Media Encoder 2200 can create several different types of audio and video streams.

Although all are a type of IP video format, each has certain properties that make it more attuned to a specific streaming video application. Cisco Digital Media Encoder 2200 was designed for creating video content in a reduced resolution to allow the content to be streamed across the Internet to be played back on a computer or a handheld mobile device.

Table 2-1

lists all formats supported by Cisco Digital Media Encoder 2200 with suggested application uses. All of these formats can be used for many different applications.

Description

Handheld devices and mobile phones

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.

Tutorial

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

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.

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.

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.

2-6

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.

For example, you can stream Windows Media at full resolution at 1 Mbps and the same time stream

RealVideo at CIF resolution at 300kbps.

Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200

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.

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.

Stopping an Encoding Session

To stop an encoder, press the <STOP> button.

Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200

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.

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.

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 them promptly 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 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.

Video & Audio Settings

Regardless of the encoder type, all types require that you set the audio and video properties. These values are the same for all encoder types except for the added color space setting for AVI and MPEG-4.

You can enable or disable video and/or audio by clicking the check box next to Source under Video

Settings and/or Audio Settings. When enabled, the Input, Signal, Proportions, Size fields under Video

Settings, and the Input field under Audio Settings, as shown in the following screenshot.

Although the Cisco Digital Media Encoder 2200 is a single channel encoder, meaning you can capture from two independent audio and video sources at any given time, you can capture multiple streaming formats and resolutions simultaneously from the same video source. To accomplish this, the video source is seen as multiple inputs denoted by incrementing decimal values. They appear in the following manner:

Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200

Encoder Preset (A, B, and C)

The audio source settings include the choices set forth below.

Warning Ensure that all of the encoders using the same video Proportion and Size settings also use the same video and audio source settings. For example, all encoders capturing at Standard proportion and CIF size are set to Osprey-5x0 Video Device 1.1 while encoders capturing at Standard proportion but QCIF resolution are set to Osprey-5x0 Video Device 1.2.

Set Input for both video and audio to match the connectors on the back of the encoder to which you have connected your video and audio source. This could be Composite or S-Video, or SD SDI for video input and Unbalanced, XLR Balanced, XLR AES/EBU, or embedded SDI for audio input.

When you performed the First Start Setup, you determine if your video signal was NTSC or PAL. The

Signal field adds granularity for regional NTSC, PAL, and SECAM settings. If you are uncertain which setting applies, refer to the owner’s manual for the video source you have connected to the encoder hardware.

The Proportions setting uses the term Standard, meaning square pixels for a VGA monitor, and

CCIR-601, meaning elongated pixels for a TV monitor. Choose the setting that reflects the type of display on which your content will be viewed. For example, if you will be streaming your video on the

Internet to be viewed on a computer monitor, select Standard. If the inaccurate setting is selected, your streaming video will be distorted.

The Size field refers to the pixel size of the encoded video. The standard sizes are as follows:

• Full-size for full screen video

CIF for video scaled from full-size to one-fourth size

QCIF for video scaled from full-size to one-fourth of CIF size

You can also specify a custom size for your video. This is useful when capturing video to be played on a mobile video device that requires a non-standard size for compatibility.

If you select Custom from the drop-down menu, two additional fields will appear allowing you to type in the exact size you want the resulting video to be.

Note If you specify a video size that is not compatible with the color space of your source video, the encoder will automatically correct the size to the closest compatible setting when you click the Submit button.

The color space format setting, entitled Format, is available only in AVI and MPEG-4 Encoder

Properties and appears as an additional field under the Size setting (see below).

Now that you have completed all of the Video and Audio settings, you can proceed to the encoder type settings at the bottom of the page.

Streaming Properties

As previously stated, these settings will vary according to the encoder type. Please refer to each encoder properties page setting in this document for further explanation and detail on the Streaming Properties

Settings and Advanced Streaming Settings sections of each encoder.

Advanced Streaming Settings

This section includes the following topics:

SimulStream, page 2-29

Deinterlace, page 2-31

SimulStream

SimulStream employs filters to change the appearance of an image or part of an image by altering the shades and colors of the pixels in some manner. Filters are used to increase brightness and contrast as well as to add a wide variety of textures, tones and special effects to a picture. SimulStream filters have two interrelated purposes, as follows:

They allow applications to enumerate and list video capture and preview pins or streams (each with different settings) as named entries in their video device select lists. The video device driver can be configured to show multiple filters per device. Each filter has one preview pin and one capture pin.

Standard applications have the capability to access a particular filter without any custom programming specialized for Osprey devices.

Each filter has independent settings for cropping, default output size, watermarks, and captions that can be stored between sessions. Compared with the previous “pin-based” method, no requirements are necessary for a particular startup order to associate settings with instantiations.

Please see the Enable SimulStream dialog box below.

The checkbox next to Enable SimulStream at the top of the dialog box, when checked, enables

SimulStream to run for the currently selected encoder.

The encoder includes a full SimulStream license installed for each A/V channel, and this checkbox controls full SimulStreaming.

Note When you change the Enable SimulStream status and click Submit, you must restart the appliance. If you do not, SimulStream may become partially active, but the capture devices may be incorrectly named, and their pins may be incorrect.

Show filters per device

With the Show filters per device control, you can set the device driver to expose multiple filters per device for enumeration and selection by encoders. If, for example, 5 filters per device are chosen, device lists in applications will show four entries for the currently chosen device. For device 1, they are designated as 1.1, 1.2, 1.3, 1.4, and 1.5.

Note The number of filters you request will not display or work correctly until the system is restarted.

Note While it is possible to expose and enumerate multiple filters per device, the practical number of working filters will be less. The practical number of filters depends on the capability of the appliance, the types of filtering enabled, the types of scaling and color format conversions requested per encoder, and the type of processing employed. If the appliance has multiple capture channels, the number of filters is the total across all channels. In addition, some types of processing, such as deinterlacing and gamma corrections, which are performed once per channel may, in this case, occur multiple times. In summary,

Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200

Encoder Preset (A, B, and C) an appliance can support multiple concurrent filters on one device if the processing per filter is light.

However, only 2 or 3 simultaneously running filters can be supported if the processing load inside or outside the driver is particularly heavy.

Deinterlace

The Deinterlace field has four drop-down choices. These choices are Off, Auto, Inverse Telecine, and

Motion Adaptive, as you can see below.

In further explanation of each choice, please see the following definitions.

Off —Performs no deinterlacing of any kind.

Auto—Applies inverse telecine deinterlacing to all telecine video. Applies motion adaptive deinterlacing to all video that is not telecine. Switches dynamically between the two modes as the content changes. Available for NTSC video only.

Inverse Telecine—Applies inverse telecine deinterlacing to all telecine video. Performs no deinterlacing of video that is not telecine. Available for NTSC video only.

Motion Adaptive—Applies motion adaptive deinterlacing to all video.

Deinterlace settings are applied and stored per-device and are applied to all filters and pins associated with a device.

Motion Adaptive Deinterlace

Motion adaptive deinterlace is an algorithm for deinterlacing pure video (non-telecine) content. It detects which portions of the image are still, and which portions are in motion, and then applies different processing to each scenario. Motion Adaptive Deinterlace is the only type of deinterlacing that uses

Motion Threshold under Advanced Streaming Settings—Simulstream.

OL-17938-01

Telecine and Inverse Telecine

Telecine video is NTSC video which was originally created on film at 24 frames per second. In the telecine conversion process, certain fields are repeated in a regular, recurring sequence. If a telecined sequence is viewed directly on a progressive screen, interlacing artifacts will be visible.

The process called “inverse telecine” is the reverse of “telecine” — inverse telecine drops the redundant fields and reassembles the video in a 24 fps progressive format. Interlacing artifacts are 100 percent removed. If the video is viewed at 24 fps, you will see the exact timing and sequencing that was on the original film. If the video is viewed at 30 fps, every fifth frame will be repeated. However, there will be no deinterlacing artifacts.

Telecine and inverse telecine only apply to NTSC video. They are not used for PAL and SECAM video.

The Auto and Inverse Telecine button choices will be disabled when either PAL or SECAM is selected as the video standard.

Encoder Preset (A, B, and C)

Motion Threshold

Motion Threshold adjusts the threshold of difference from spatially- and temporally-related pixels, which are judged to be “motion.” If you enter a higher value, the number of pixels in motion will be greatly reduced. If you enter a lower value, the number of motion pixels greatly increases until the entire screen, more or less, is considered in motion. The recommended default is 16.

Sharp and Smooth Motion

When the Sharp Motion radio button is selected, detail in motion areas will be sharper, but at the expense of somewhat jagged diagonal edges.

When the Smooth Motion radio button is selected, more loss of detail will occur in motion areas, but edges will be smoother.

Since the eye does not clearly see detail in areas of motion—and edge artifacts are highly intrusive—the

Smooth algorithm is preferred for most applications. The Smooth algorithm uses a bit more CPU.

Both algorithms treat still areas in the same fashion, and there should be no loss of detail in still areas.

AVI Encoder Settings

AVI is an uncompressed audio and video storage format and, therefore, only has the ability to save to a file. You can type in a unique name for the generated AVI file and modify the directory path to the location the file will be stored. Clicking the Default Folder link will insert the path of the default folder for file storage on the encoder. By default the path is d:\AVFILES\.

Note It is not recommend that you store files in any other directory on the encoder.

Once you have saved your file to the encoder internal hard drive, we recommend that you move the drive to another external storage device such as a USB drive or a network drive for backup purposes.

After you have input your settings, click the Submit button at the bottom of the page to save your changes.

Warning If you click away from the current page to another web page without clicking Submit, your changes will be lost.

Flash Encoder Settings

The Flash Encoder Settings are similar to the AVI settings for saving the audio and video to a file.

However, Flash adds some additional frame and bit rate controls. The frame rate changes the frames per second at which the video will be encoded. The audio format setting can be used to modify the audio frequency and changes stereo to mono. The bit rate settings pertain to the amount of data per second the audio and video are captured. Decreasing the bit rate for both or either will decrease the playback viewing quality.

The Flash encoder creates a Flash format audio and video file. You can type in a unique name for the

Flash file (.flv).

The following figure illustrates the screen you will see after creating an encoder through the Niagara

SCX Web Interface.

The Advanced MPEG Video Settings provide you with the ability to choose the MPEG Type required for your output. These MPEG Types include the following:

H.264–MP4: H.264, MPEG-4, Part 10, or AVC (Advanced Video Coding) was designed for very high-data compression while maintain better quality than its predecessor, H.263. It was also created to address a broad range of applications from low bit rate to high bit rate and from low resolution such as cell phones to high resolution such as broadcast. The encoder’s H.264 is Baseline Profile.

H.264–3G2: This setting will create an H.264 stream stored in a 3G2 container.

H.264–3GP: This setting will create an H.264 stream stored in a 3GPP container.

MPEG4–MP4: MPEG-4, Part 2, or H.263, is designed for situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth or device size. Examples of video applications for H.263 are cell phones, some low end video conferencing systems, and surveillance systems. H.263 is important for legacy handheld devices that do not support H.264.

Note By default, the encoder’s H.263 uses Simple Profile unless you select the Enable B Frames option. If B frames are enabled, then the resulting stream will be Advanced Simple Profile.

MPEG4–3G2: This setting will create an H.263 stream stored in a 3G2 container.

The Advanced MPEG Audio Settings, provide you with several Audio Formats, Audio Types, Audio

Encoders, and Bitrates from which to choose. These choices include several options as to audio sampling, and whether the audio is to be encoded monophonically (mono) or stereo.

The Audio Type setting is only related to AAC Encoding. If you select AMR in the Audio Encoder field, this setting is not used. The Audio Type field provides you with a drop-down box, which includes the following two choices:

Main: This format is the same as Low Complexity, but adds backward prediction.

Low Complexity (LC): The simplest and most widely used and support AAC audio format.

Note Depending on the player on which the resulting stream will be heard, either choice—Main or Low

Complexity—will use a specific set of tools to encode the audio stream. You should make your choice based on the requirement of the playback software or device. The most widely supported format is LC profile.

The Audio Encoder settings provides you with a drop-down box, which includes the following three choices:

AAC (Advanced Audio Coding): A standardized, lossy compression and encoding scheme for digital audio. AAC achieves better audio quality than MP3 and has been named a standard by the

Motion Picture Experts Group (MPEG)

AMR-NB (Adaptive Multi-Rate Narrow-Band – 8 kHz): An audio data compression scheme optimized for speech coding. AMR was adopted as the standard narrowband speech codec by 3GPP and is widely used in GSM.

AMR-WB (Adaptive Multi-Rate Wide-Band – 16 kHz): An audio data compression scheme optimized for speech coding. AMR was adopted as the standard wideband speech codec by 3GPP and is widely used in GSM.

Note The default settings will enable multicast streaming. If this is not desired, change the IP address for

Group to the IP address of the server to which you want to stream from the encoder.

The save SDP File field will require a name and destination path for the resulting SDP file created when the stream is started. If you are streaming to a Helix

, a Quicktime, or a Darwin server, refer to its respective documentation or online message boards for setup details specific for the individual streaming server.

Note You can stream point-to-point by selecting a share destination directory for the saved SDP file.

Remember to disable multicasting by entering in the IP address of the PC to which you want to stream.

For example, if you want another PC to view the stream, save the SDP file to a share folder on the local drive. The other PC can open the SDP file and the stream can be played in a Quicktime or other MPEG-4 compatible streaming player. Since MPEG-4 encoding can be CPU intensive, it is not recommend that you view the stream on the same system as the encoder unless you have a very powerful system

(dual-core processors or better). Doing so may overtax the host CPU which will cause video quality degradation and encode session failure.

OL-17938-01

Broadcast Method: There are several different broadcast types for streaming Real format video to a

Helix Server, as follows:

Push, Account-Based Login (Helix Server): Account-based, push broadcasting allows you to send a stream to Helix Server version 9 or later. In this method, the encoder maintains a monitoring connection to Helix Server. This connection allows it to pass a user name and password to authenticate access to the server. Helix Server uses this connection to send statistics about the broadcast stream back to the encoder.

Push, Password-Only Login (Helix Server): Unlike account-based broadcasting, password-only broadcasting does not establish a monitoring connection. Therefore, this type of broadcasting requires less network overhead, but receives no feedback from Helix Server. This broadcast method allows you to send a live stream to Helix Server version 9 or later. However, you must set up the server as a receiver in a splitting arrangement. Please refer to Helix Server documentation for details.

Push, Multicast (Helix Server): In a multicast, the encoder can deliver the same broadcast stream to any number of Helix Servers without increasing its outgoing bandwidth. The Helix Servers will need to be pre-configured for a multicast from the encoder. Refer to your Helix Server documentation for details.

Pull (Helix Server): In pull broadcasting, the encoder begins to generate broadcast packets as soon as you start the encoding. However, it does not deliver the broadcast stream until Helix Server requests the stream, which occurs when the first RealPlayer

®

user requests the broadcast. In that

User Guide for Cisco Digital Media Encoder 2200

2-39

Chapter 2 Getting to Know the Cisco Digital Media Encoder 2200

Encoder Preset (A, B, and C) way, Pull broadcasting saves bandwidth between the encoder and Helix Server when no one is viewing the broadcast. This broadcast method allows you to send a stream to Helix Server version

9 or later.

Legacy Push (8.x, 7.x, G2): The legacy push method is similar to the account-based push method.

However, the legacy push does not use a monitoring connection to provide server feedback and statistics and is not as robust a broadcast method as an account-based push. Use this broadcasting method only when sending a broadcast stream to a server that predates Helix Server version 9, such as RealSystem Server G2, 7, or 8.

Transport Protocol: When you use a push broadcast method, you specify whether to use UDP or TCP upon delivering the broadcast stream to Helix Server. UDP is the preferred protocol due to the lower network overhead. But you may want to use TCP when delivering the broadcast over a lossy environment.

For the Server Address field, enter the IP address or DNS name of the Helix Server used for the broadcast, such as 207.188.7.176 or helixserver.example.com.

For the Port/Port Range field, specify the HTTP port on Helix Server. The default value is port 80, which is the server's default HTTP port. If multicasting, indicate the range of ports on the Helix Server receivers where the broadcast packets will be sent. The encoder and Helix Server negotiate the actual ports to use once the broadcast begins. The default range is from 30001 to 30020.

If using a Multicast Address, enter the multicast address for the broadcast stream in the Multicast

Address field. The Multicast Address must be in the range 224.0.0.0 to 239.255.255.255.

The Listen Address field is the IP address of your machine where Helix Producer will listen for resend requests from the server.

The listen address sets the IP address that Helix Mobile Producer Live uses to listen for packet resend requests from Helix Server. For the listen address, you can use one of the following possible values:

Automatic: This is the safest setting, and will work with most firewall configurations

System IP: The IP address of the machine

System IP 2: The second IP of the machine is multi-homed

• An IP address typed in by the user

If your Helix Mobile Producer Live machine has multiple IP addresses, enter the IP address that Helix

Mobile Producer Live should use for communications from Helix Server. If you are broadcasting through a firewall performing network address translation (NAT), set the listen address to the IP address of the firewall or the value 0.0.0.0. The 0.0.0.0 value tells Helix Server to allow a Helix Mobile Producer Live connection from any IP address. The connection still requires the valid password, however.

In the Stream Name field, enter a name for the broadcast stream. This name resembles a clip name and should use the appropriate extension, either .rm for a constant bit rate stream or .rmvb for a variable bit rate stream. This name appears in the broadcast URL.

The Path (optional) field specifies a virtual path, which can be used for archiving or splitting on Helix

Server. Use a simple name followed by a forward slash, such as news/.

In the User Name and Password fields, enter the User Name and Password defined in each Helix Server receiver definition. The broadcast connection fails if the value is incorrect.

Frame Rate, or frame frequency, is the measurement of the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (fps), or simply hertz (Hz).

The next series of fields activate the Real Encoder’s filters to improve video and audio quality. These filter settings will depend upon the type of content you are streaming and your subjective preference. It is recommended you experiment with these settings and view their results on a test capture.

The Cisco Digital Media Encoder 2200 features integrated de-interlacing and inverse telecine filters that automatically apply when needed. This allows the encoder to perform at maximum efficiency.

Note We recommend that you do not enable the Real Encoder de-interlace and inverse telecine filters since applying filters multiple times can produce undesirable results and consume additional system resources.

Enable SureStream

: SureStream allows you to encode the broadcast stream for multiple audiences.

However, each primary stream or substream you choose increases the processor load during encoding and adds to the outgoing bandwidth requirements. For example, with SureStream enabled, you can choose the 56k Dial-up audience and the 128k Dual ISDN audience. In addition, with SureStream enabled, the encoding might require twice as much processing power.

Regardless of whether or not you enable SureStream, you must choose at least one Audience Selection for your stream.

You can also choose to output to a file while streaming or output only to a file. Type in a unique name for the file.

Note If you use the same name as a current file, the current file will be overwritten.

Windows Media is both a storage format and a streaming format. In addition to the ability to output to a file, the Windows Media encoder can stream to a Windows Media Server. The settings for Windows

Media encoder include the ability to set parameters for connecting and streaming to the server.

First, select a Windows Media Capture Profile from the drop-down menu.

Note Some Windows Media Capture Profiles have pre-defined video resolutions and input selections. When you select a Windows Media Capture Profile, verify that your current video and audio settings have not been modified. If they have been modified, simply change these settings back to their previous settings and click the Submit button.

When streaming audio and video, there are two methods of delivery, as follows:

Pull: Using this method, the encoder begins to generate broadcast packets as soon as you start the encoding. However, it does not deliver the broadcast stream until Windows Media Server requests the stream. This method does not provide a secure connection to the server and should only be used if the encoder and server reside within the same network firewall.

Push: Using this method, the encoder maintains a secure connection to Windows Media Server. This connection allows the encoder to pass a user name and password to authenticate access to the server.

To enable clients to pull the stream from Cisco Digital Media Encoder 2200, you set up a session and begin broadcasting directly from the encoder. Clients (Windows Media servers or players) can connect to the stream at any time by using the following URL format:

• http://IP_address:port (for Internet connections)

• http://encoding_computer_name:port (for LAN connections)

By default, the encoder supports up to 50 direct connections during a broadcast.

Video & Audio Settings

The properties page for each encoder type uses the same Video and Audio Settings except for the added color space setting for AVI and MPEG-4.

OL-17938-01

You enable or disable video and/or audio by clicking the check box next to Source: When Source is enabled, the Source, Input, Signal, Proportions, Size, Format, and Input fields can be edited.

Source: This field displays a drop-down list of devices available on the encoder. The Cisco Digital

Media Encoder 2200 is a two channel encoder, so there are two physical sets of audio and video inputs can be used at any one time. However, you can capture multiple streaming formats and resolutions simultaneously from this one set of video inputs. Video source is seen as multiple inputs denoted by incrementing decimal values. They appear in this manner:

Osprey 5x0 Video Device 1.1

Osprey 5x0 Video Device 1.2

Osprey 5x0 Video Device 1.3

Osprey 5x0 Video Device 1.4

Set Input for both video and audio to match the video and audio inputs on the back of the encoder to which you connected your video and audio source. This would be either Composite, S-Video or SDI for video input and Unbalanced, XLR Balanced, XLR AES/EBU or SDI for audio input.

When you performed the First Start Setup, you determined if your video signal was NTSC or PAL. The

Signal field adds granularity for regional NTSC, PAL, and SECAM settings. If you are uncertain which setting applies, refer to the owner’s manual for the video source that you have connected to the encoder.

The proportion setting uses the term Standard, meaning square pixels for a VGA monitor, and

CCIR-601 meaning elongated pixels for a television monitor. Choose the setting that reflects the type of display on which your content will be viewed. For example, if you will be streaming your video on the Internet to be viewed on a computer monitor, select Standard. Selecting the incorrect setting can make the streaming video appear distorted.

The Size field refers to the pixel size of the encoded video. The standard sizes are as follows:

Full for full screen video

CIF for video scaled from full size to ¼ size

• QCIF for video scaled from full size to ¼ of CIF size

You can also specify a custom size for your video. This is useful when capturing video to be played on a mobile video device that requires a non-standard size for compatibility.

User Guide for Cisco Digital Media Encoder 2200

Chapter 3 Using the Ease Menu and Niagara SCX Web Interface

Niagara SCX Web Interface

If you select Custom from the drop-down menu, two additional fields will appear allowing you to type in the exact size you want the resulting video to be.

Note If you specify a video size that is not compatible with the color space of your source video, the encoder will automatically correct the size to the closest compatible setting when you click the Submit button.

The color space format setting is only available in AVI and Flash encoder properties and appears as an additional field under the Size setting (see below).

Now that you have completed all of the Video and Audio settings, you can proceed to the encoder type settings at the bottom of the page. As previously stated, these settings will vary according to the encoder type.

Advanced Streaming Settings

SimulStream and DirectShow Filters

SimulStream filters have two interrelated purposes, as follows:

• They allow applications to enumerate and list video capture and preview pins or streams (each with different settings) as named entries in their video device select lists. The video device driver can be configured to show multiple filters per device. Each filter has one preview pin and one capture pin.

Standard applications have the capability to access a particular filter without any custom programming specialized for Osprey devices.

• Each filter has independent settings for cropping, default output size, watermarks, and captions that can be stored between sessions. Compared with the previous “pin-based” method, no requirements are necessary for a particular startup order to associate settings with instantiations.

Chapter 3 Using the Ease Menu and Niagara SCX Web Interface

Please see the Enable SimulStream checkbox below.

Niagara SCX Web Interface

OL-17938-01

The checkbox next to Enable SimulStream at the top of the dialog box, when checked, enables

SimulStream to run for the currently selected encoder.

The encoder includes a full SimulStream license installed for each A/V channel, and this checkbox controls full SimulStreaming.

Note When you change the Enable SimulStream status and click Submit, you must restart the appliance. If you do not, SimulStream may become partially active, but the capture devices may be incorrectly named, and their pins may be incorrect.

Show filters per device

With this control, you can set the device driver to expose 1 to 10 filters per device for enumeration and selection by encoders. If, for example, 4 filters per device are chosen, device lists in applications will show four entries for the currently chosen device. For device 1, they are designated as 1.1, 1.2, 1.3, and

1.4.

Note The number of filters you request will not display or work correctly until the system is restarted.

Note While it is possible to expose and enumerate up to 10 filters per device, the practical number of working filters will be less. The practical number of filters depends on the capability of the appliance, the types of filtering enabled, the types of scaling and color format conversions requested per encoder, and the type of processing being done. If the appliance has multiple capture channels, the number of filters is the total across all channels. In addition, some types of processing, such as deinterlacing and gamma corrections, which are performed once per channel may, in this case, occur multiple times. In summary, an appliance can support 5, 6, or more concurrent filters on one device if the processing per filter is light.

However, only 2 or 3 simultaneously running filters can be supported if the processing load inside or outside the driver is particularly heavy.

Auto—Applies inverse telecine deinterlacing to all telecine video. Applies motion adaptive deinterlacing to all video that is not telecine. Switches dynamically between the two modes as the content changes. Available for NTSC video only.

Inverse Telecine—Applies inverse telecine deinterlacing to all telecine video. Performs no deinterlacing of video that is not telecine. Available for NTSC video only.

Motion Adaptive—Applies motion adaptive deinterlacing to all video.

Deinterlace settings are applied and stored per-device and are applied to all filters and pins associated with a device.

Motion Adaptive Deinterlace

Motion adaptive deinterlace is an algorithm for deinterlacing pure video (non-telecine) content. It detects which portions of the image are still, and which portions are in motion, and then applies different processing to each scenario.

Telecine and Inverse Telecine

Telecine video is NTSC video which was originally created on film at 24 frames per second. In the telecine conversion process, certain fields are repeated in a regular, recurring sequence. If a telecined sequence is viewed directly on a progressive screen, interlacing artifacts will be visible.

The process called Inverse Telecine is the reverse of Telecine — it drops the redundant fields and reassembles the video in a 24 fps progressive format. Interlacing artifacts are 100% removed. If the video is viewed at 24 fps, you will see the exact timing and sequencing that was on the original film. If the video is viewed at 30 fps, every fifth frame will be repeated. However, there will be no deinterlacing artifacts.

Telecine and inverse telecine only apply to NTSC video. They are not used for PAL and SECAM video.

The Auto and Inverse Telecine buttons will be disabled when either PAL or SECAM is selected as the video standard.

Motion Threshold

Motion Threshold adjusts the threshold of difference from spatially- and temporally-related pixels, which are judged to be “motion.” If you enter a higher value, the number of pixels in motion will be greatly reduced. If you enter a lower value, the number of motion pixels greatly increases until the entire screen, more or less, is considered in motion. The recommended default is 16.

Sharp and Smooth Motion

When the Sharp Motion radio button is selected, detail in motion areas will be sharper, but at the expense of somewhat jagged diagonal edges.

When the Smooth Motion radio button is selected, more loss of detail will occur in motion areas, but edges will be smoother.

Since the eye does not clearly see detail in areas of motion—and edge artifacts are highly intrusive—the

Smooth algorithm is preferred for most applications. The Smooth algorithm uses a bit more CPU.

Both algorithms treat still areas in the same fashion, and there should be no loss of detail in still areas.

AVI Encoder Settings

AVI is an uncompressed audio and video storage format and therefore has only the ability to save to a file. You can type in a unique name for the generated AVI file and modify the directory path to where the file will be stored. Clicking the Default Folder link will insert the path of the default folder for file storage on the encoder. By default, the path is D:\AVFILES\.

Note We do not recommend that you store files in any other directory on the encoder.

Once you save your file to the encoder’s internal hard drive, we recommend that you move it to another external storage device such as a USB drive or a network drive.

The Flash encoder settings are similar to the AVI settings for saving the audio and video to a file. To enable streaming to file, ensure the Output to a File box is selected. Flash adds some additional frame and bit rate controls. The frame rate changes the frames per second that the video will be encoded. The audio format setting can be used to modify the audio frequency and changes stereo to mono. The bit rate settings pertain to the amount of data per second the audio and video are captured. Decreasing the bit rate for both or either will decrease the playback viewing quality.

The Advanced MPEG Video Settings provide you with the ability to choose the MPEG Type required for your output. As set forth in descriptions of the MPEG Types, these include the following:

H.264–MP4: H.264, MPEG-4, Part 10, or AVC (Advanced Video Coding) was designed for very high-data compression while maintain better quality than its predecessor, H.263. It was also created to address a broad range of applications from low bit rate to high bit rate and from low resolution such as cell phones to high resolution such as broadcast. The encoder’s H.264 is Baseline Profile.

H.264–3G2: This setting will create an H.264 stream stored in a 3G2 container.

H.264–3GP: This setting will create an H.264 stream stored in a 3GPP container.

MPEG4–MP4: MPEG-4, Part 2, or H.263, is designed for situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth or device size. Examples of video applications for H.263 are cell phones, some low end video conferencing systems, and surveillance systems. H.263 is important for legacy handheld devices that do not support H.264.

Note By default, the encoder’s H.263 uses Simple Profile unless you select the Enable B Frames option. If B frames are enabled, then the resulting stream will be Advanced Simple Profile.

MPEG4–3G2: This setting will create an H.263 stream stored in a 3G2 container.

MPEG4–3GP: 3GP is a multimedia container format defined by the Third Generation Partnership

Project (3GPP) for use on 3G mobile phones. It stores video streams such as MPEG-4 or H.264 and audio streams such as AMR or AAC. This setting will create an H.263 stream stored in a 3GPP container. There are two defined standards for this format:

3GPP for GSM based mobile phones

3GPP2 for CDMA based mobile phones

H263–MP4: MPEG-4, Part 2, or H.263, is designed for situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth or device size. Examples of video applications for H.263 are cell phones, some low end video conferencing systems, and surveillance systems. H.263 is important for legacy handheld devices that do not support H.264.

Note By default, the encoder’s H.263 uses Simple Profile unless you select the Enable B Frames option. If B frames are enabled, then the resulting stream will be Advanced Simple Profile.

H263–3G2: This setting will create an H.263 stream stored in a 3G2 container.

H263–3GP: This setting will create an H.263 stream stored in a 3GPP container.

Note The Encoder Quality setting is currently not active and will not affect the results of the encoding stream or file.

Note Some players, such as Quicktime

The Advanced MPEG Audio Settings, provide you with several Audio Formats, Audio Types, Audio

Encoders, and Bitrates from which to choose. These choices include several options as to audio sampling, and whether the audio is to be encoded monophonically (mono) or stereo.

OL-17938-01

The Audio Type setting is only related to AAC Encoding. If you select AMR in the Audio Encoder field, this setting is not used. The Audio Type field provides you with a drop-down box, which includes the following two choices:

Main: This format is the same as Low Complexity, but adds backward prediction.

Low Complexity (LC): The simplest and most widely used and support AAC audio format.

Note Depending on the player on which the resulting stream will be heard, either choice will use a specific set of tools to encode the audio stream. You should make your choice based on the requirement of the playback software or device. The most widely supported format is LC profile.

The Audio Encoder settings provides you with a drop-down box, which includes the following three choices:

AAC (Advanced Audio Coding): A standardized, lossy compression and encoding scheme for digital audio. AAC achieves better audio quality than MP3 and has been named a standard by the

Motion Picture Experts Group (MPEG)

AMR-NB (Adaptive Multi-Rate Narrow-Band – 8 kHz): An audio data compression scheme optimized for speech coding. AMR was adopted as the standard narrowband speech codec by 3GPP and is widely used in GSM.

AMR-WB (Adaptive Multi-Rate Wide-Band – 16 kHz): An audio data compression scheme optimized for speech coding. AMR was adopted as the standard wideband speech codec by 3GPP and is widely used in GSM.

Note When you select AMR Encoder for audio, the audio will automatically be encoded using 8 kHz mono for playback on cell phones. When you select AMR-WB for audio, you must change the

Audio Format to be 16 kHz, 16 bit, mono, for playback on cell phones.

The Audio Bitrate drop-down box provides you with several choices, ranging from 8 to 320.

The web interface for the encoder includes options for Streaming Properties and Advanced Streaming

Properties. As to the broadcast type you choose, you have the option to check the Enable Streaming box. Please see the

“Real Encoder Settings (Helix)” section on page 3-34

for a more detailed description of enabling pull. Another option provides you with the abilities to Save to Portable Media and provide a Media Title.

Under the Advanced Streaming Settings feature, you have the options to output to a file while streaming or output only to a file. You must type in a unique name and location for this file.

Check the Save to file box if you would like to save the encoded content to a file. Enter a file destination in the field provided. By default, this folder is set to D:\AVFiles\.

Check the Save to Portable Media boxif you would like to save the stream from portable media to a file.

Note Remember the file name is referenced to the encoder system not to the system that is running SCX

Explorer.

When SCX Manager and SCX Explorer are not on the same computer, always start your browse for files at My Network Places and work down or enter the entire file pathname beginning with the system name

(for example, \\fileserver\c\videos). If you simply enter a file name, you may inadvertently browse your local computer when the media file resides on the remote computer.

OL-17938-01

Note The default settings will enable multicast streaming. If this is not desired, change the IP address for

Group to the IP address of the server to which you want to stream from the encoder.

The save SDP File field will require a name and destination path for the resulting SDP file created when the stream is started. If you are streaming to a Helix

®

, a Quicktime, or a Darwin server, refer to its respective documentation or online message boards for setup details specific for the individual streaming server.

Note You can stream point-to-point by selecting a share destination directory for the saved SDP file.

Remember to disable multicasting by entering in the IP address of the PC to which you want to stream.

For example, if you want another PC to view the stream, save the SDP file to a share folder on the local drive. The other PC can open the SDP file and the stream can be played in a Quicktime or other MPEG-4 compatible streaming player. Since MPEG-4 encoding can be CPU intensive, it is not recommend that you view the stream on the same system as the encoder unless you have a very powerful system

(dual-core processors or better). Doing so may overtax the host CPU which will cause video quality degradation and encode session failure.

Real Encoder Settings (Helix)

Real (Helix) is both a storage format and a streaming format. In addition to the ability to output to a file, the Real Encoder can stream to a Helix Server. The settings for the Real Encoder include the ability to adjust parameters for connecting and streaming to the server.

Broadcast Method: There are several different broadcast types for streaming Real format video to a

Helix Server. They are as follows:

Push, Account-Based Login (Helix Server): Account-based, push broadcasting allows you to send a stream to Helix Server version 9 or later. In this method, the encoder maintains a monitoring connection to Helix Server. This connection allows it to pass a user name and password to authenticate access to the server. Helix Server uses this connection to send statistics about the broadcast stream back to the encoder.

Push, Password-Only Login (Helix Server): Unlike account-based broadcasting, password-only broadcasting does not establish a monitoring connection. Therefore, this type of broadcasting requires less network overhead, but receives no feedback from Helix Server. This broadcast method allows you to send a live stream to Helix Server version 9 or later. However, you must set up the server as a receiver in a splitting arrangement. Please refer to Helix Server documentation for details.

3-34

User Guide for Cisco Digital Media Encoder 2200

OL-17938-01

Chapter 3 Using the Ease Menu and Niagara SCX Web Interface

Niagara SCX Web Interface

Push, Multicast (Helix Server): In a multicast, the encoder can deliver the same broadcast stream to any number of Helix Servers without increasing its outgoing bandwidth. The Helix Servers will need to be pre-configured for a multicast from the encoder. Refer to your Helix Server documentation for details.

Pull (Helix Server): In pull broadcasting, the encoder begins to generate broadcast packets as soon as you start the encoding. However, it does not deliver the broadcast stream until Helix Server requests the stream, which occurs when the first RealPlayer

®

user requests the broadcast. In that way, Pull broadcasting saves bandwidth between the encoder and Helix Server when no one is viewing the broadcast. This broadcast method allows you to send a stream to Helix Server version

9 or later.

Legacy Push (8.x, 7.x, G2): The legacy push method is similar to the account-based push method.

However, the legacy push does not use a monitoring connection to provide server feedback and statistics and is not as robust a broadcast method as an account-based push. Use this broadcasting method only when sending a broadcast stream to a server that predates Helix Server version 9, such as RealSystem Server G2, 7, or 8.

Transport Protocol: When you use a push broadcast method, you specify whether to use UDP or TCP upon delivering the broadcast stream to Helix Server. UDP is the preferred protocol due to the lower network overhead. But you may want to use TCP when delivering the broadcast over a lossy environment.

For the Server Address field, enter the IP address or DNS name of the Helix Server used for the broadcast, such as 207.188.7.176 or helixserver.example.com.

For the Port/Port Range field, specify the HTTP port on Helix Server. The default value is port 80, which is the server's default HTTP port. If multicasting, indicate the range of ports on the Helix Server receivers where the broadcast packets will be sent. The encoder and Helix Server negotiate the actual ports to use once the broadcast begins. The default range is from 30001 to 30020.

If using a Multicast Address, enter the multicast address for the broadcast stream in the Multicast

Address field. The Multicast Address must be in the range 224.0.0.0 to 239.255.255.255.

The Listen Address field is the IP address of your machine where Helix Producer will listen for resend requests from the server.

The listen address sets the IP address that Helix Mobile Producer Live uses to listen for packet resend requests from Helix Server. For the listen address, you can use one of the following possible values:

Automatic: This is the safest setting, and will work with most firewall configurations

System IP: The IP address of the machine

System IP 2: The second IP of the machine is multi-homed

An IP address typed in by the user

If your Helix Mobile Producer Live machine has multiple IP addresses, enter the IP address that Helix

Mobile Producer Live should use for communications from Helix Server. If you are broadcasting through a firewall performing network address translation (NAT), set the listen address to the IP address of the firewall or the value 0.0.0.0. The 0.0.0.0 value tells Helix Server to allow a Helix Mobile Producer Live connection from any IP address. The connection still requires the valid password, however.

In the Stream Name field, enter a name for the broadcast stream. This name resembles a clip name and should use the appropriate extension, either .rm for a constant bit rate stream or .rmvb for a variable bit rate stream. This name appears in the broadcast URL.

The Path (optional) field specifies a virtual path, which can be used for archiving or splitting on Helix

Server. Use a simple name followed by a forward slash, such as news/.

In the User Name and Password fields, enter the User Name and Password defined in each Helix Server receiver definition. The broadcast connection fails if the value is incorrect.

Frame Rate, or frame frequency, is the measurement of the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (fps), or simply hertz (Hz).

The next series of fields activate the Real Encoder’s filters to improve video and audio quality. These filter settings will depend upon the type of content you are streaming and your subjective preference. It is recommended you experiment with these settings and view their results on a test capture.

The Cisco Digital Media Encoder 2200 features integrated de-interlacing and inverse telecine filters that automatically apply when needed. This allows the encoder to perform at maximum efficiency.

Note We recommend that you employ the deinterlace and the inverse telecine filters under either Streaming

Properties or under Advanced Streaming Properties/Deinterlace, but not both since applying filters multiple times can produce undesirable results and consume additional system resources.

Enable SureStream ™ : SureStream allows you to encode the broadcast stream for multiple audiences.

However, each primary stream or substream you choose increases the processor load during encoding and adds to the outgoing bandwidth requirements. For example, with SureStream enabled, you can choose the 128k Dual ISDN and the 64k Single ISDN audiences. In addition, with SureStream enabled, the encoding might require twice as much processing power.

Regardless of whether or not you enable SureStream, you must choose at least one Audience Selection for your stream.

You can also choose to output to a file while streaming or output only to a file. Type in a unique name for the file.

Note If you use the same name as a current file, the current file will be overwritten.

If they have been modified, simply change these settings back to their previous settings, and click the Submit button.

When streaming audio and video, there are two methods of delivery, as follows:

Pull: Using this method, the encoder begins to generate broadcast packets as soon as you start the encoding. However, it does not deliver the broadcast stream until Windows Media Server requests the stream. This method does not provide a secure connection to the server and should only be used if the encoder and server reside within the same network firewall.

Push: Using this method, the encoder maintains a secure connection to Windows Media Server. This connection allows the encoder to pass a user name and password to authenticate access to the server.

Digital Rights Management (DRM) for Windows Media

You can protect your content by using a technology called Digital Rights Management (DRM). Niagara

SCX allows you to encrypt your content with DRM technology while you are encoding. You can apply

DRM while encoding to a file and when broadcasting a stream. Users will be required to obtain a license to play the content. This license contains the key to unlock the content and the rights that govern its use.

Note Licenses are issued by a third-party license provider, so you must set up an account with a third-party license provider to protect your content.

Niagara SCX automatically detects any available DRM profiles imported on the encoding system. If there are no DRM profiles installed, the DRM functions in Niagara SCX are disabled. In order to enable the DRM function in Niagara SCX, you must do the following:

1.

Set up an account with a third-party license provider, and create a DRM profile.

2.

3.

Import the DRM profile by using the Windows Media Encoder application included with Niagara

Streaming Systems or available as a free download from Microsoft Corporation

(http://www.microsoft.com).

Restart the encoding system on which Niagara SCX is installed, allowing the software to auto-detect and enable its DRM functions.

Importing a DRM Profile

If you have not already done so, set up an account with a licensed provider and create a DRM profile.

Once the DRM profile is created, you must use Windows Media Encoder to import the profile on the encoding system.

Windows Media Encoder is included in Niagara Streaming Systems that have Niagara SCX version 5.0 or later installed. To access the desktop of the encoder, use Windows Remote Desktop Connection on a computer that resides on the same network.

Note When connecting to an encoder by using a Remote Desktop Connection, it is extremely important that you set the Local Resources to Leave at remote computer before connecting to the system.

To set this appropriately, open Remote Desktop Connection.

All alerts defined on the encoder Alerts page are logged on the View Alerts page when those alerts occur.

Once a user has cleared an alert by using the Help or i button on the front panel of the encoder, the alert is cleared from the View Alerts log page.

Alternatively, the Cisco Digital Media Encoder 2200 system informs you of an alert when the Alarm

Indicator Light on the front panel of the system turns red. When this occurs, to determine what the alert is, you must press the Help or i button, which will cycle the alert occurring.

For more information, see the

“The Help, or “i” Button, the Niagara SCX Web Interface, and Their Alert

Settings” section on page 3-59

The Help, or “i” Button, the Niagara SCX Web Interface, and Their Alert Settings

The Help button, or “i” button, on the front panel of the encoder allows you to view the alerts currently occurring in the Cisco Digital Media Encoder 2200. Directly below is a diagram of the Help or “i” button, which is located on the front panel of the encoder. The Help or “i” button allows you to view alerts of many types that can occur on the encoder based on the types of alerts you request of the system to notify you.

Note An alert is not necessarily an indication of a fault occurring. You might want to be made aware of changes in the system, which have nothing to do with errors that could occur on a Cisco Digital Media

Encoder 2200. For example, you might want a notification set to signal you as to when an encoder has started or when as to when an encoder has stopped.

To view alerts occurring, you have a choice to view the alerts through use of the encoder or the Niagara

SCX Web Interface. If you use the web interface, the following is the first page of the Niagara SCX Web

Interface you will see to View Alerts.
