Take the podcast 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
Question: Are Podcasts are always
in the RSS 2.0 format?
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 audio
Question: Are there any fee
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
Question: What file formats are
acceptable in a podcast?
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 enclosure.
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 Music Store.
