This section describes how you can share files by adding content to your iTunes U site. You can use iTunes U to share audio, video, PDF, and ePub files. iTunes, which displays the iTunes U pages, is designed primarily for audio and video files. Therefore, audio and video file types have importance within iTunes U because the software is designed to work in conjunction with iTunes, iPod, iPhone, and iPad.
Depending on your site set up, you can add content to your iTunes U site using:
A feed group
A feed course
The Upload and Manage Files page
iTunes U Web Services
Using feeds, your institution hosts content on a local server instead of uploading content to Apple’s servers, allowing the content to remain inside your institution’s network. This technique offers multiple forms of distribution from a single source, allows the content to appear in iTunes U and other podcast aggregation destinations without multiple efforts, and allows your institution to provide much more content than if it was all uploaded to Apple’s servers. iTunes U allows up to 300 enclosures in a feed. However, for performance and usability, Apple recommends an upper limit of 50 enclosures in a feed. If a feed has a large number of enclosures, your content can be more difficult for users to search and browse, thus making your content less discoverable. For information on creating feeds for iTunes U, see “Creating an iTunes U - Specific RSS Feed.”
Internet Explorer on Windows might have performance limitations when uploading files. For more information, see the Microsoft Help and Support Site at http://support.microsoft.com/default.aspx?scid=kb;en-us;329781.
It is recommended that your audio files be in AAC or MP3 format with the appropriate file extension (.m4a or .mp3) and your video files be in MPEG-4 format with H.264 compression and with the appropriate file extension (.mp4, .m4v, or .mov). For more information, see “Supported Formats.”
