Video podcast
Video podcast (sometimes shortened to vodcast) is a term used for the online delivery of video on demand video clip content via Atom or RSS enclosures. The term is used to distinguish between podcasts which most commonly contain audio files and those 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. Web television series are often distributed as video podcasts.
However, the term podcast has from its inception described the distribution of digital media files, including video and audio via RSS enclosures and hence the terms video podcast, vodcast, and less commonly vidcast, are redundant.
Technology and history
From 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.
