Podcast is a combination of the term "iPod" (a portable media plaer) and the term "broadcast". This technology enables the visitors of a web site to download audia or video files to their portable players or podcast software.
What is a podcast?
A podcast is a series of media and/or video files which can be downloaded to a portable player, to a podcast software or to an online service offering podcast support.
Subscribing to a podcast enables the user to automatically load new episodes of a podcast to their computer or portable media device.
What do I need to be able to download and play back podcasts?
In order to listen to or view podcasts, you need a so-called "podcatcher", which enables you to download, subscribe and play back podcasts.
There are various podcatching solutions, such as:
Podcast software (such as "iTunes" or "Zune") which enables you to either load podcasts to your portable player or watch or listen to them on your computer.
Mobile devices, which support downloading, subscribing and playback of podcasts directly from the internet (to watch video podcasts, you need a mobile device offering video functionality).
Online services supporting the integration of podcast to a personalised home page (such as e.g. "myAOL").
