General System Requirements
Hardware:
- Monitor resolution of 1024 x 768 or greater (1280 x 1024 or greater recommended).
- Speakers or headphones and a sound card with the ability to stream audio.
- Processor speed better than 1.0GHz with 512MB RAM.
Operating System:
- Windows XP or newer
- Macintosh OS X 10.4 or newer
Browser:
- Internet Explorer 8 or newer (IE 9 or newer recommended for best performance)
- Google Chrome 10 or newer
- Firefox 4.0 or newer
- Safari 4.1 or newer (Macintosh only)
Browser Plug-ins:
- JavaScript/ActiveX: To ensure the proper functionality of LearnLive webcasts, rebroadcasts, and self-study sessions, make sure to enable JavaScript and ActiveX in your browser.
- Adobe Flash Player: Our webcasts, rebroadcasts, and self-study sessions take advantage of the Adobe Flash Player for multimedia content. To install the free * Flash Player, go to get.adobe.com/flashplayer
- Adobe Reader: Handouts may be provided in Adobe .pdf format. Many browsers can display this format in the browser window without additional plug-ins. To install the free Adobe Reader, go to get.adobe.com/reader
- Java (Presenter only): In order to take advantage of screen sharing, the Java web plugin must be installed and activated. If you are not a presenter using screen sharing, you may disregard this requirement. *Please Note:* the latest version of Google Chrome web browser no longer supports Sun's Java plug-in.
Popup Blockers:
Portions of this site (uploading files, launching the media player) require pop-up windows to be enabled for LearnLive domains. For details on how to do this, view our popup blocker tutorial.
Internet Connection:
- Streaming audio requires an internet connection capable of 30kBytes/sec, and streaming video requires between 90kBytes/sec and 300kBytes/sec, depending on the video quality.
- Archived files require a connection capable of of 90kBytes/sec or better.
- A high speed internet connection such as an intranet connection, DSL, or cable modem is required.
- Firewall, if present, must allow RTMP traffic on port 443 (SSL) and on 1935 or 80 (or RTMP tunneling on port 80 with HTTP) for the following IP address ranges: 64.94.115.64/26 (64.94.115.65 – 64.94.115.126)
Note: The LearnLive platform uses an RTMP (TCP) based protocol, which by default runs on port 1935. If that connection does not succeed, RTMP will try to run on port 80 or try to tunnel RTMP over HTTP on port 80 (Some firewall configurations or proxy setups may prevent the use of tunneling). We recommend communicating over port 1935 for maximum performance. Port 80 tunneled can impact performance.
Compatability with Mobile Devices (Tablets, smart phones, etc.)
At this time, the LearnLive media player (the interface for displaying self-study, webcast, and rebroadcast content) is not compatible with iOS devices (iPad, iPhone) nor with other mobile devices. A mobile-friendly media player is in development.
The university itself will run on most mobile devices, as will the administrative site; however some functionality, such as file upload/download and editing cue points, will not function. While the LearnLive administrative and university sites can be accessed via mobile devices, we do not guarantee functionality when used on any device other than the desktop browsers listed above.
Additional Requirements for Specific Features and Special Cases
If you are a presenter:
- In order to publish audio, you will need a microphone attached to your computer. Many newer laptops have a camera and microphone built-in. In most cases, the camera is compatible with the Adobe Flash plugin, however, to make sure, you should test your hardware with the presenter interface well before any live event.
- In order to publish video, you will need a video camera attached to your computer. Many newer laptops have a camera and microphone built-in. In most cases, the camera is compatible with the Adobe Flash plugin, however, to make sure, you should test your hardware with the presenter interface well before any live event.
- In order to take advantage of screen sharing, the Java web plugin must be installed and activated. If you are not a presenter using screen sharing, you may disregard this requirement.
If you are an administrator:
- In order to use the cue point editor to time slides against an audio/video track in a self-study, you will need to use Internet Explorer 9 or newer, or Firefox or Chrome. Internet Explorer version 8 does not support modern video embedding techniques. For more information see Assign_cue_points_for_self-study_session.
- In order to safely upload large video files (approximately > 5 MB) from your desktop, you will need to use Internet Explorer 9 or newer, or Firefox or Chrome. Internet Explorer version 8 does not support the file utility we use to enable large files to upload smoothly.
