Re: What is the difference between podcasting and videocasting with rss? by Jonathan Miller on Jul 7, 2006 at 12:56:11 am
Videocasting (video) and podcasting (audio) both use the same mechanism for distribution: an RSS feed.
An RSS feed is an XML file that, to put it simply, just tells your RSS reader (in this case let's say iTunes) that there are files available for download...and where those files can be downloaded from.
So, a typical "podcast" RSS feed can can contain instructions for downloading audio files (usually mp3), video files or a combination of audio files and video files.
You can also think of it this way:
A podcast is usually an audio file that can be subscribed to via an RSS feed.
A Videocast is a video file that can be subscribed to via an RSS feed.
Personally, I don't like the term "videocast" or "vodcast" or "vlog" so I simply say "video podcast". But that's just my preference.
