Video podcasts

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.

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.

Channeling of on-demand content has major benefits for both publishers and subscribers. Publishers can still bundle content for their audience. Subscribers can consume content on-demand and don't need keyboard or mouse interfaces to choose channels and items, much similar to zapping through regular TV stations, and new episodes show up automatically, so the technology is ideal for on-the-go (portable media players and mobile phones) and living room mass media consumption.

Uses in Education

Video podcasts enable students and teachers to share information with anyone anytime. If a student is absent, they can download the podcast of the recorded lesson. It can be a tool for teachers or administrators to communicate curriculum, assignments and other information with parents and the community. Teachers can record book talks, vocabulary or foreign language lessons, international pen pal letters (podcast pals!), music performance, interviews, debates. Video podcasting can be a publishing tool for student oral presentations. Audio podcasts can be used in all these ways as well. It also allows people to leave a journal.
