We recently worked with Paul Emerson in the President's Office to record this year's "Welcome" message delivered by ASU President, Michael Crow. The Office of the President has been actively exploring the integration of new media into the university, and they are committed to practice what they preach. Along this line, Paul contacted us a few weeks ago inquiring about the requirements and available options for producing video blogs. This year's Welcome message seemed to be an excellent first foray into the new medium, and we were happy to help.

This video will likely be available across a number of our digital distribution channels including the Office of the President Podcast page above, ASU@iTunesU, our standard web streaming channels, as well as other open and public channels that we are experimenting with including OurMedia and others.

Technical Notes - This video is about 6 1/2 minutes long (delivered in a single, nearly perfect take as is so often the case with President Crow). We shot this on miniDV using a Panasonic DVX100, filtered with both Neutral Density and Black Diffusion filters. President Crow was lit with two banks of Kino Flo fluorescent instruments that provide cool soft and directional light. We utilized existing shades on the windows in the background and also coated them with CO gel material. Finally, a single Lowel ViP instrument was used to accent additional background elements.

What is Podcasting?

Podcasting is the merging of two technologies: Downloadable media (audio, usually) and RSS.

Downloadable media is simply a file (such as MP3) stored on a server that users can download and listen to. RSS is a technology that allows a user to subscribe to a podcast and have episodes automatically downloaded to their computer.

Creating Podcasts at ASU, Overview

Podcasts at ASU may be used for either general public information such as promotional materials, guest lectures, public events, etc. or for delivering course content (lectures, videos, even digital print materials) to registered students.

ASU on iTunes U
ASU on iTunes U provides a user friendly, accessible podcast distribution mechanism for the ASU community. ASU on iTunes U leverages the Apple iTunes U infrastructure to facilitate storage and distribution of ASU podcast content; making it is possible for every ASU faculty member and researcher to effectively and efficiently provide podcast course material to students, colleagues, fellow researchers--the global community.

ASU on iTunes U, a Step-by-Step Guide to ASU podcast distribution

1. Determine if your podcast will be for Public or Private distribution. Public content may be downloaded by anybody, and is most suitable for guest lectures, promotional materials, and the like, while Private content may be restricted to a select group of ASURITE ID holders (e.g., course lectures intended for only registered students of the course)

2. Determine who will be responsible for maintaining your ASU on iTunes U podcast "Course/Channel". ASU on iTunes U content may be maintained by one or more individuals, so long as they have an ASURITE ID.

   Two Primary "Roles" are allocated for maintaining ASU on iTunes U content:

   • The "Instructor" Role has full editing privileges, including organizing the structure, content, and graphics of an ASU on iTunes U Course/Channel
   • The "TA" Role has the ability to upload and delete content in pre-defined areas designated by the Instructor
   • FYI, other Roles within the ASU on iTunes U environment presently include "Student," "All" (the general public), and "Authenticated/Unauthenticated." These Roles are primarily related to downloading content rather than uploading and maintaining content. It is not necessary to identify these Roles during your request, but they are mentioned here merely for informational purposes as such terminology may be present in other related ASU on iTunes U documentation.
   • ASURITE ID's are required for associated roles of Instructor and TA within ASU on iTunes U

3. Request your ASU on iTunes U "Course/Channel" using the ASU Course Request online web form located at http://my.asu.edu/courserequest
   • NOTE: Not all ASU on iTunes U podcasts need to be associated with an ASU Course. However, ASU on iTunes U is related to other ASU 'Learning Management Systems' such as Blackboard and Sakai as part of the overall ASU Distributed Learning Platform, and therefore the same ASU mechanism (my.asu.edu/courserequest) is used to establish and administer related environments and associated roles such as "Instructors" and "TA's" within each.

   Presently, the output ASU on iTunes U Course/Channel requests from my.asu.edu/courserequests notifies staff within the ASU University Technology Office, who will create your ASU on iTunes U Course/Channel within the Apple environment. You may be contacted personally for additional information to verify that your ASU on iTunes U Course/Channel is created in the most suitable manner possible.

4. Access to ASU on iTunes U Courses and Channels

   Instructor/TA Editing

   • Once your ASU on iTunes U Course/Channel has been created, you may access it for Editing and for Uploading Content using the "ASURITE" button located on the ASU iTunes U home page (itunes.asu.edu). As either an Instructor or TA you will be able to Edit your ASU on iTunes U Course/Channel and Upload content using the provided links with ASU on iTunes U Course/Channel that will only appear to Instructors and TA's. Additionally, as an Instructor you may select the "Edit Page" links and the "Edit Access" links which provide additional tools for adjusting the organizational structure, graphics, and access to you ASU on iTunes U Course/Channel.

   Private - Student Downloading of Content

   • If you have identified your ASU on iTunes U Course/Channel as 'Private' then only registered students enrolled in the ASU Course associated with the designated ASU on iTunes U Course/Channel will be able to see and download content. These students will also need to login to ASU on iTunes U using the the "ASURITE" button located on the ASU iTunes U home page itunes.asu.edu.
   • Additionally, you may place a link directly to your ASU on iTunes U Course/Channel on any web page (e.g., within Blackboard or Sakai) which will take students directly to your content after their identity (their ASURITE ID) has been verified. [Tip: Right Click on any content within an ASU on iTunes U Course/Channel to "Copy iTunes URL" to obtain the link to be placed in an external web page]
