A webcast is a media presentation distributed over the internet using stream media technology to distribute a single content source to many simultaneous listeners or viewers. This can be live or on demand. The largest webcasters include radio and t.v stations who simulcast their output through online TV or online radio streaming as well as a multitude of internet only stations. The term webcasting usually refers to non interactive linear streams or events. Eg Iplayer, Radio one etc.
Webcasting is also used in commercials for investor relations presentations such as annual general meetings In E learning and for related communications activities Eg of this is Skype. However webcasting does not bear much, if any, relationship to web conferencing, which is designed for many to many interaction.
The ability to webcast is usually cheap and accessible technology that has allowed independent media to flourish. There are many independent shows that broadcast regularly online. Often produced by average citizens in their homes talking about interests and topics.
We was shown three websites and apps that able you to upload and edit your webcasts for three on the internet.
These were:
- http://www.ustream.tv/new
- http://www.telestream.net/
- Collabracam
These were interesting as I knew that you could produce your own webcast online but I never realised that some of the sites are free. This is something I would love to develop on in the future
