By the term Pod casting, we mean delivery of audio contents by Internet. The word “pod casting” is an amalgam of the word broadcasting and the name of the popular MP3 player from Apple Computer called the “iPod”. It is not necessary that an iPod is required to pod cast. In fact, pod casts can be used with a variety of digital audio formats and play on almost any MP3 player or portable digital audio device - as well as any brand of desktop computer or laptop.
Definition: Pod casting is the process of capturing an audio event, song, speech, or mix of sounds and then posting that digital sound object to a Web site or “blog” in an RSS feed. Once the contents are posted, users can subscribe to a web page containing these RSS feeds and download them directly into an audio management program like Windows Media Player, Music Match etc. For this, they can use specialized newsreaders like iPodder or iPodderX.
After having synchronized their portable audio device with their personal computer, the user can listen to the audio contents whenever he wishes since the pod casts are automatically transferred to that device.
Pod casting may look similar to a Digital Video Recorder (DVR) but the aspect in which it differs is that the recorded content is delivered in it?s final format to a portable device that is independent of the recording.
After having created the audio contents using audio capture tools and audio editing tools, the file is transferred to the website by different methods like FTP/HTTP etc. Then the content is prepared in a specific structured format via XML tags to form the RSS feeds, which can be downloaded using RSS newsreaders such as iPodder or iPodderX.
