Video podcast (sometimes shortened to vidcast or vodcast) is a term used for the online delivery of video on demand video clip content via Atom or RSS enclosures. The term is an evolution specialized for video, coming from the generally audio-based podcast and referring to the distribution of video where the RSS feed is used as a non-linear TV channel to which consumers can subscribe using a PC, TV, set-top box, media center or mobile multimedia device. Podcasts have always contained audio or video content, so the terms 'vodcast' and 'video podcasting' are redundant.
Technology and historyFrom a web server, a video podcast can be distributed as a file or as a stream. Both methods have their advantages and disadvantages. Downloading complete video podcasts in advance gives the user the ability to play the video podcasts offline on, for example, a portable media player. A downloaded version can be watched many times with only one download, reducing bandwidth costs in this case. Streaming allows seeking (skipping portions of the file) without downloading the full video podcast, better statistics and lower bandwidth costs for the servers; however, users may have to face pauses in playback caused by slow transfer speeds. A podcast client may work with a separate, or integrated player. One such example of the latter is iTunes, which is an unusual case of a web feed aggregator being added to a media player rather than vice versa. Video Podcast IconAn official icon for video podcasting has yet to be established. This has led to the proposal of several independently created graphics. Most of them are available under a Creative Commons license. Timeline
