Pictures say much more than words:
Video podcast (sometimes shortened to vlog, 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.
A video podcast may be produced:
a) from a video footage
b) from an images slide show
c) A simple audio podcast will be produced from a .mp3 file.
For you as a business it is important how a podcast can improve your marketing mix in order to achieve better communication and more sales. Video podcasts are a great way get the best results.
More technical details:
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 podcasting 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.
