A useful new tool for securely sharing video online is now available to the NIU community, the Helix Media Library (HML). The HML is an on-campus streaming media server that allows faculty, students and staff to store media content (audio and video). Even more intriguing is that the HML is integrated with the Blackboard Learn course management system, making it easier to incorporate media into Blackboard courses by encoding and converting media so that it is optimized for streaming and able to play on most devices, including computers, laptops, tablets, and smartphones.
In the past, faculty who wished to post media content to Blackboard, especially video, may have experienced difficulty when adding it to their course. The process was unwieldy and awkward, yielding inconsistent results because the Blackboard server was not able to optimize the streaming video.
In addition, because video files are often larger than other course content, uploading media content could quickly fill up Blackboard course quotas. As a result, faculty might have resorted to using outside services such as YouTube or Vimeo, to post and distribute content. Now, with the HML, it is much easier to post audio and video files to this on-campus server and share them within the university or publicly. The HML operates behind a firewall, with content regularly backed-up by NIU.
The HML is a Mashups tool appearing in the Text Box Editor (see below). When you click the Mashups button, you can select the Helix Media Library link to begin the process of uploading content.
This means that media content can be uploaded anywhere in Blackboard that there is access to the text box editor, by both faculty and students. For example, faculty can add video or audio as an Item in a content area, or while creating Announcements, Assignments, and posting a Discussion Board topic. Students can upload their own media for a video assignment or when collaborating on the discussion board, blogs, wikis, or journals.
Currently, every NIU faculty, staff, and student has an HML account, with 4 GB of space available. However, if you need more space, you can submit a request to DoIT (Division of Information Technology) to increase that for free in 4 GB increments. Individual files can be up to 2 GBs in size, which allows you to upload longer video segments. Since video is uploaded into HML accounts, Blackboard course quota space remains unaffected.
When a video is uploaded, the Permissions feature allows you to determine who has access to view it. If the video is uploaded from within Blackboard, the ‘Personal’ setting allows only the instructor and students enrolled in the course to view the content. Selecting ‘Protected’ makes the content available to all NIU users (i.e., faculty, staff, students). Selecting ‘Public’ opens the content to potentially all online users.
You can check out your own HML account by logging into http://hml.niu.edu. You will be asked to authenticate with your university-assigned username and password.

In addition, the Faculty Development and Instructional Design Center offers a specialized workshop periodically, Adding Video to Your Blackboard Course Using the Helix Media Library, to train faculty and staff about how to use this tool. One-on-one consultation is also available.
