quiz and test your knowledge.
Question: Are there any size limitations to podcasts?
Answer: There are no maximums or minimums when
it comes to podcast size. Obviously, the larger files might intimidate
listeners with a slow connection. Podcasts can be successful at
any size, generally wise podcasters balance the file size and the
quality of their show.
Question: What are ID3 Tags?
Answer: ID3 tags consist of meta data that
describe the contents of the audio file (typically ID3 tags relate
to MP3 files). ID3 tags generally contain information related to
the audio file, including things like title of the audio file, the
artist, album, or other relevant information. There is speculation
that podcasting search engines and directories will use the information
contained in the ID3 tags to categorize, search, and group podcasts
in the future.
Question: Are Podcasts are always in the RSS 2.0
Answer: No, while RSS 2.0 was the first version
to support enclosures, RSS version 1 also now includes an enclosure
tag for podcasting. While the current RSS 1.0 supports podcasting,
RSS 2.0 is by far the more popular format for those podcasting.
This is not only because RSS 2.0 was the first standard to support
enclosures, but also due to the fact that Apple iTunes uses RSS
2.0 for it's podcasts.
Question: Can podcasts be restricted to a specific
group of listeners?
Answer: Yes, while there are no provisions
in the RSS 2.0 specification for passwords or protecting files,
as with any web documents, podcasts can be password protected by
placing it in a subdirectory. You can use any security mechanism
available on the http server to protect the entire feed or the actual
Question: Are there any fee based podcasts?
Answer: Yes, while the model has not yet been
widely adopted, some publishers have experimented with providing
fee based "commercial-free" podcasts. Rather than charging advertisers
to advertise in the podcasts, the publishers have monetized the
podcasts by charging listeners for the contents of the podcast.
Typically the audio file is password protected and only subscribers
are able to download or listen to the file. The model is similar
to that which the cable shows HBO/Showtime use, where they charge
a fee for premium content. It is likely that educational podcasts,
or language lessons will adopt this model.
Question: What file formats are acceptable in a
Answer: It really depends on what your definition
of a podcast is. Initially the term podcast referred to any RSS
feed that contained an audio file as an enclosure. The usage of
the term podcast has expanded and now many people consider any RSS
feed that includes a file in the enclosure field to be a podcast.
In other words, many people use the term podcast to refer to an
RSS feed that has a video file, or power point presentation or other
Technically you can put just about any type of file
in the enclosure field. If you are referring to a traditional audio
podcast, for the sake of compatibility, most podcasters use either
MP3 or M4a. The added benefit of using an MP3 or M4a file is that
both formats are also supported by iTunes, which allow people to
expand their podcast with iTunes tags and include it in the iTunes
