iTunes U puts the power of the iTunes Store to work for colleges, universities, and other educational organizations, so users can easily search, download, and play education content just like they do with music, movies, and TV shows.
iTunes U Public Site Manager is an enhanced version of the iTunes U service for editing and managing public sites in the iTunes Store. iTunes U Public Site Manager replaces your existing iTunes U administrative tools, becoming the tool dedicated to helping you manage your public site content within the iTunes Store (private/internal site content remains unchanged). With iTunes U Public Site Manager, you have new administrative tools for managing your site and controlling your organization's content and pages in the iTunes U area of the iTunes Store. Using iTunes U Public Site Manager you can define one or more administrators and contributors to help you create, edit, and manage your iTunes U site and content.
In iTunes U Public Site Manager your site has a flattened structure and a new layout and design, allowing you to focus on your content. The new tools make it easier to reorganize and feature content most engaging to your users.
iTunes U Public Site Manager provides a publishing feature, allowing you to stage edits to your site and publish changes incrementally.

Original iTunes U public site administrators and managers should read this document to learn about transitioning to iTunes U Public Site Manager, as well as how to organize their institution’s site, including how to design and customize pages.
iTunes U Public Site Manager requires:

In order to guarantee a consistent user experience, always use the latest version of iTunes.
Safari version 4.0.3 or later for Mac or Windows
For provider-hosted content, to optimize your server bandwidth and performance, enable byte-range serving. Enabling byte-range requests for streaming and resumption of downloads on your web server allows you to send portions of content at a time and can improve the performance of the content caching system iTunes U Public Site Manager uses.
Once your site is live in the iTunes U area of the iTunes Store, your institution's content is available for download on a wide variety of devices (for example, iTunes, iPad, and iPhone) and to a broad worldwide audience with varying server bandwidth and performance. To ensure a good user experience, consider appropriate file size and compression when encoding your content.
iTunes U Public Site Manager supports the distribution of compressed audio and video files. Apple recommends using the following formats for your audio and video content:
Audio files (AAC, MP3) with appropriate file extensions (.m4a, .mp3). For best results during playback, Apple recommends converting MP3 files greater than 32 megabytes (MB) to AAC format. For AAC audio files, Apple recommends the following specifications:
Audio Format: Baseline Low-Complexity Profile with AAC-LC (Music)
Data Rate: Up to 160 Kbps
Channels: Stereo (in .m4v, .mp4, and .mov formats)
Output Sample Rate: 48 kHz
Encoding Quality: Better
Video files (MPEG-4 with H.264 compression) with appropriate file extensions (.mp4, .m4v, .mov). For best results with iPod, Apple recommends using MPEG-4 with H.264 compression with the following specifications:
Video Format: MPEG-4 with H.264
Data Rate: Up to 1.5 Mbps
Image Size: 640 x 480 pixels
Frame Rate: 30 frames per second
Key Frame: Every 24 frames
Audio Tracks: Baseline Low-Complexity Profile with AAC-LC audio up to 160 Kbps
You can also use iTunes U Public Site Manager to distribute Portable Document Format (PDF) and electronic publication (ePub) files. ePub files must pass ePubCheck 1.0.5, include only files listed in the manifest, and use UTF-8/16 characters. For more details, read the complete ePub specification at http://www.idpf.org/specs.htm. PDF and ePub files appear in iTunes U and the iTunes U library with a book icon. To open a PDF or ePub file, download the file and double-click the file. iBooks or another reader is required (download the free iBooks application from the App store). You cannot preview a PDF or ePub file in iTunes U.
iTunes U Public Site Manager supports images embedded in items in JPEG or PNG format with appropriate file extensions (.jpg, .jpeg, .png) in RGB Color Model. JPEG images can include EXIF or JFIF, but not both.
iTunes U Public Site Manager is designed to support public content and therefore does not support hosting content on a secure server using an SSL URL scheme (https).
If you are using QuickTime to create and edit video content, it is recommended that you export your videos by choosing “Movie to iPod” from the Export pop-up menu in QuickTime Pro. For more information, see http://www.apple.com/quicktime/.
Notes:
Some MP3 audio files, specifically ID3 version 1.x tagged files, have known issues displaying item artwork information. To use specific artwork with these audio files, Apple recommends either converting the files to MP3 files tagged as ID3 version 2.4 or converting the files to the AAC file type format (.m4a).
iTunes U does not support the downloading of WAV or AIFF file formats on the iPod, iPhone, or iPad.
Due to video file profile level requirements, iTunes U might not play some files on the iPad without re-encoding the files. For more information, see the iPad audio playback and TV and video requirements at http://www.apple.com/ipad/specs/.
