A podcast is a collection of audio and/or video on the Internet that can be cataloged and automatically downloaded. It has a news feed (known as RSS) that allows it to be organized in various podcasting directories. In addition, the news feed allows the podcasting directory program to automatically download new episodes.
There are 3 different types of podcasts: audio podcasts, enhanced podcasts, and video podcasts. An audio podcast is the most common and is usually an mp3 file. Enhanced podcasts have images that go along with the audio content and allow chapter markers that make it easy to navigate through the podcast. Podcasts that are enhanced are usually mp4 and AAC files that are not supported on all devices. Video podcasts are movies, complete with sound. MPEG-4 is the most popular file for video podcasts.
