Podcasting Terminology


A podcast is a series of digital media files, usually audio or video, that is downloadable via RSS feed (really simple syndication). The syndication (subscribe) aspect of the delivery is what differentiates podcasts from direct file download or streaming. Special software applications, generically known as pod catchers (such as Apple iTunes), can automatically retrieve new files associated with the podcast when they are made available.

RSS Feed

RSS stands for Really Simple Syndication and is what makes a podcast different from a downloadable file. Web feed formats are used to publish frequently updated work—such as blogs, news, audio, and video in a standardized format. An RSS document includes metadata such as publishing dates and authorship. Web feeds benefit publishers, such as professors, by letting them syndicate content automatically. RSS feeds can be read using software called an "RSS reader". RSS is signified with this standard image.
