The Media Service provides faculty with the ability to podcast audio and video. The podcast feature gives students enrolled in the course the ability to subscribe to downloadable content posted in the course. Any time additional media are made available by the instructor, the new media are delivered to the students so that they can be played in iTunes or in similar RSS-capable media programs.
Course podcasts may include recordings of lectures that you give during class and ancillary media that you wish to make available to your students. Podcasts can also provide an easy way to download "lessons" or "chapters" of media rather than downloading the lesson's files one by one.
