Podcasts

Podcasting is a non-streaming presentation of audio or video content that people can download and access from a mobile device such as an iPod. Podcasts are often release episodically, and users subscribe using RSS feeds. Sites such as iTunes allows anyone to create and distribute a podcast.

Direct Download (non-streaming video)

Videos may be hosted on a website (such as an Athena locker), but will rely on the browser to have the appropriate plugin(s) to play the video. Merely pointing to a video file using "http://" in front of the file path will make downloading the file easy, given sufficient bandwidth. Note that storage lockers have space limitations, and video files are generally very large.

Physical Media (e.g., DVDs, tape, blu-ray)

Videos maybe stored on DVDs, tape, blu-ray, hard drives, or other physical media. These can make a particularly effective strategy for Archiving.
