Prepare the Infrastructure
...
- A source: The EchoSystem SafeCapture HD or the Echo360 PRO
- A reflector: The Wowza Media Server (Wowza) to stream live Flash media content
- A sink: One or more EchoPlayers that allow students to view the content
...
- Enable licensing.
- Registering the ESS with Echo360's Collaboration and Statistics Service (only required if using chat and presence features of live webcasting).
- Configure the Wowza Media Server, including including configuring the system streaming settings for for the ESS.
- Optional - Distribute live webcasts with a CDN.
...
See Configure the Flash Media Streaming Server and Configure an External Wowza Media Server for media server configuration information as needed.
Enable Licensing
- Update the the ESS to use the EchoSelect license. This license includes live webcasting as an option.
- Do one of the following:
- If you have a site license, continue with configuration. See See Configure the Wowza Media Server
- If you have venue licenses, assign the licenses to to venues (typically classrooms) that will have live webcasting.
...
- Make sure the Wowza Media Server has a production license. Each viewer receiving the live webcast requires at least four connections to the Wowza Media Server and may need as many as seven. Development or staging licenses do not have enough connections to support a typical class.
- Estimate your anticipated media server requirements for both live webcasts and on-demand recordings. See See Deployment Planning and and Bandwidth Requirements for Capture and Media Formats.
- Install and configure your Wowza Media Server. See See Configure the Flash Media Streaming Server and and Configure an External Wowza Media Server for for external configuration instructions.
- Reconfigure the firewall ports for the the Wowza Media Server.
- Review, and if necessary, edit the Streaming Settings.
...
Echo360 does not provide a CDN integration, but you can integrate your Wowza Media Server with certain CDNs , as described in this article: http://www.wowza.com/partners.html. Please also see the push publishing article on on the Wowza Support forum. The RMTP solution described requires some custom configuration on the Wowza server.

- Determine which sections might have live webcasting, and verify those sections occur in rooms containing a SafeCapture HD device.
- Configure product group defaults and security settings for for the section.
- Configure a schedule for the section. The section section must be be scheduled in a room containing a SafeCapture HD device.
- Review the Person and Section roles for for the section. Make sure you have a Teaching Assistant assigned to the section.
- Notify the students/participants as as necessary.
The sections below explain how live webcasting configuration differs from on-demand capture configuration.
...
Security defaults for a section determine whether students need to log in to view the Echoes or live webcasts for a section, or if the section outputs, including any live webcasts, are available to anyone with access to the proper URL.
The portion of the of the Edit Section page that that contains these settings is shown in the figure below.
- Use the the Product Group drop drop-down list to select a live-enabled product group. The selected product group is passed through to each schedule you generate for this section, however, you can select a different product group for each schedule if appropriate.
Use the the Security Module drop drop-down list to identify how users access captures for this section (either live webcasts or Echoes).
- If you select Allow All, users are not required to log in to view any live webcasts or Echoes published for this section. This also means that the chat and presence capabilities for the live webcast are also disabled , because these features require users to be identified (via their logins).
- Selecting a different different Security Module will will require authentication (student login) in order to access the live webcasts or Echoes, and also allows use of the chat feature for live webcasts if you have the the Collaboration and Statistics Service configured for your system.

Configure a Schedule for a Live Webcast Section
...
Use the following steps for every section or event that needs live webcasting. The steps below assume you have already created a live-enabled product group as well as the section you must now schedule. See See Manage Product Groups and and Add a Section for more detailed information on those tasks.
- Navigate to the Schedules page (Schedule > > Schedules).

- Configure or review the Date and Time, Exclusions, Presenters, and Echo Defaults settings.
- Review or edit the Product Groups selection for the section.
- If you choose a product group for which live is required, the the Stream Live field field is checked , but grayed (dimmed) because there is no need to configure it.

For more information on providing access to the scheduled live webcast, see see Notify Students.
Administer the Live Webcast
As an Administrator, you can can monitor and and control the the live webcast as it is happening. The Instructor may also monitor and control the webcast through the the instructor interface for the live webcast.
Monitor the Live Webcast
You may want to monitor the SafeCapture HD inputs prior to the start of the live webcast, and monitor at least the initial few minutes of the presentation to make sure all of the sources are being webcast correctly. There are two ways to monitor a live webcast:
...
To monitor the webcast through the ESS interface:
- In the ESS, navigate to to Monitor > Summary.
- The Capturing tab is active by default. If there is a current live webcast being captured, it is listed on the Capturing tab along with a a Monitor link in the Streaming column, as shown in the below figure.
- Click the the Monitor link link. This opens the EchoCenter page for the live webcast section in a new tab.
- Click to join the live webcast in progress. The student view of the webcast appears, allowing you to see the output being viewed by students.
...
Below is an abbreviated procedure for this task. See See Log In to the EchoSystem SafeCapture HD for for more detailed instructions.
- In the ESS, navigate to to Configuration > Devices.
- Look for the SafeCapture HD device in the room where the live webcast is taking place. If necessary, use the Search drop-down lists to filter which devices are shown.
- Click the the MAC address for for the device. The Device Details screen opens.

- When finished, click click Stop Monitoring. If the webcast has begun, simply close the browser.
Capture Control of the Live Webcast
Live webcasts can be controlled much the same way that Ad Hoc recordings are controlled. This includes the ability to pause, resume, extend, and stop a live webcast. In fact, you use the same interface features. If you have integrated the capture appliance with an AMX or Crestron system, there are no changes to enable capture control functionality through the capture device API.
...
There are two ways to access the capture control features of a live webcast:
- Using the administrative access to the capture appliance
- Using the instructor interface of the live webcast screen
To use the administrative access method:
- Navigate to Configuration > Devices.
- Look for the SafeCapture HD device in the room where the live webcast is taking place. If necessary, use the Search drop-down lists to filter which devices are shown.
- Click the MAC address for the device. The Device Details screen opens.
- In the Device Details screen, click
...
