What is Podcasting? • A podcast is a multimedia file that is distributed by subscription over the Internet using syndication feeds, for playback on mobile devices and personal computers. • Like 'radio', it can mean both the content and the method of delivery; the latter may also be termed podcasting. • The host or author of a podcast is often called a podcaster.
What is Podcasting? • Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital audio formats by its ability to be downloaded automatically using software capable of reading feed formats such as RSS. • RSS means Real Simple Syndication, an internet broadcast method.
The History of Podcasting? • The concept of podcasting was suggested as early as 2000 and its technical components were available by 2001, then implemented in the program Radio Userland an internet radio system. • In 2003 regular podcasts started showing up on well-known Web sites and software support spread.
The History of Podcasting? • The editors of the New Oxford American Dictionary declared "podcasting" the 2005 word of the year. • Defining the term as "a digital recording of a radio broadcast or similar program, made available on the Internet for downloading to a personal audio player". • The name has aroused some controversy for implying one needs an iPod to listen to podcasts, when in fact all portable media players will play them.
How Podcasting Works • The publish/subscribe model of podcasting is a version of push technology, in that the information provider chooses which files to offer in a feed and the subscriber chooses among available feed channels. • While the user is not "pulling" individual files from the Web, there is a strong "pull" aspect in that the receiver is free to subscribe to (or unsubscribe from) a vast array of channels.
How Podcasting Works • Podcasting is an automatic mechanism whereby multimedia computer files are transferred from a server to a client, which pulls down XML files containing the Internet addresses of the media files. • In general, these files contain audio or video, but also could be images, text, PDF, or any file type.
How Podcasting Works • The content provider begins by making a file (for example, an MP3 audio file) available on the Internet. • This is usually done by posting the file on a publicly available webserver. • The only requirement is that the file be accessible through some known URI (a general-purpose Internet address). • This file is often referred to as one episode of a podcast.
How Podcasting Works • A consumer uses a type of software known as an aggregator, such as a podcast receiver, to subscribe to and manage their feeds. • A podcast specific aggregator is usually an always-on program which starts when the computer is started and runs in the background. • They work exactly like any newsreader someone would use to manage other web subscriptions. • The downloaded episodes can then be played, replayed, or archived as with any other computer file.
Why choose Podcasting? • Podcasting's initial appeal was to allow individuals to distribute their own "radio shows," but the system quickly became used in a wide variety of other ways; • distribution of school lessons, • official and unofficial audio tours of museums, • conference meeting alerts and updates, • police departments to distribute public safety messages.
Uses of Podcasting • Podcasting can be used in a number of different ways, including: • A way for people and organizations to avoid regulatory bodies that would not allow a program to be broadcast in traditional media. • A way for news organizations to distribute audio or video as an addition to their existing text (or mostly text) news products. • Education: Podcasting can be categorised as an m-learning strategy for teaching and learning. • These are only a few of the many uses of podcasting
