Podcasting
From Wikipedia, the free encyclopedia.
Podcasting is a term used to describe a group of technologies for distributing audio or video programs over the Internet
using a publisher/subscriber model. It differs from earlier online
delivery because it automates the transfer of digital media files to
the user's computer for later use. Podcasting enables independent
producers to create self-published, syndicated "shows," and gives
broadcast radio or television programs a new distribution method.
Subscribing to podcasts allows users to collect individual programs
from a variety of sources for listening or viewing at the user's
convenience. In contrast, traditional broadcasting provides only one
source at a time, and the time is broadcaster-specified. "Streaming"
media files from the Internet removes the specified-time restriction,
but is still limited to a single source. "Aggregating" programs from multiple sources is a major part of the attraction of podcast-listening.
Any digital audio player or computer
with audio-playing software can play podcasts. From the earliest
RSS-enclosure tests in 2000 and 2001, feeds have been used to deliver
video files as well as audio, and other media such as photographs and
text are transferable by podcast. The term "cast," however, still
refers largely to audio distribution.
Podcasting's essence is all about creating
content (audio or video) for an audience that wants to listen when they
want, where they want, and how they want.
