Podcasts

• Definition– Digital media file distributed over the internet using

syndication feeds for playback on portable media players or computers

– Podcasting– Podcaster – author of podcast

• Podcasts: syndicated, subscribed to, downloaded automatically when new content is added (via RSS/Atom)

• iPod – 1st portable media player to accept podcasts via podcasting scripts

Page 22: Web Syndication  & Podcasts

How Podcasting Works

• 1. User creates a media file• 2. User uploads file to some webserver (file can

be accessed by public)• 3. User modifies RSS/Atom/XML document by

adding an “item” which contains the file information

• 4. Subscriber’s feed is notified that there is an update via a periodic check (how often is setup by the user or default programmed value)

• 5. File can be downloaded to computer or portable media device

Social Podcasting
