Podcast Hosting

Finding Podcast Hosting

For anyone who wants to begin creating a podcast,
podcast hosting is the most important part. Before
anyone can begin distributing a podcast, they need a
place to store the files and keep the feed file that will
tell their subscribers about the new episodes available.
The first thing required is a domain name where the site
will be located. Many domain registrars are available
who will help one register a domain name for a small
fee. Once the domain is registered, hosting is required,
and again there are many different companies willing to
do the hosting for a small fee. One of those is
bluehost.com, but many others are available. When
looking for a host, the most important thing is to make
sure that a lot bandwidth and storage space is available
and cheap. Since podcasting deals with large media
files, a lot of disk space will be taken up storing the
files and bandwidth will be eaten quickly when they are
downloaded by the subscribers.

After podcast hosting has been acquired, it needs to be
used and the site needs to be set up. The DNS addresses
of the site need to be set to the addresses that the host
provides you so that the servers that underlie the
internet will know where your site is. DNS addresses
can be set by going to the domain registrar that was
used to acquire the domain and inputting the addresses
provided by the host. After that is done, it will take a
few days before the master list the domain registar
updates will be shared throughout the internet and all
name servers know where to find your specific domain.
You can then go about setting up your own podcast.

Using the podcast hosting you now have, you will need
to look at the disk space allocated to the site using
something called and FTP browser. The host may
provide one as part of their hosting plan, but if not there
are many available free to choose from. Using the FTP
browser, log on to the host and upload a file called
dircaster.php after editing it to fit the specifics of the
site. Dircaster.php is an easy to find piece of coding that
generates a feed file by looking at the contents of its
directory or folder. The individual episodes to be
podcasted can then be uploaded to the same folder as
dircaster.php for cataloging. Make sure that all the meta
data, or information about the mp3 file is correct before
doing so.

The podcast hosting you now have will allow you to
distribute a podcast. It would be best to upload more to
the site, such as an index page that tells visitors about
the podcast and provides the address of the file
dircaster.php on your site. When they subscribe to that
file, the podcast client they use will access it and receive
information about the latest podcasts available.

Free Podcast Videos

Finding Free Podcast Videos

Anyone can easily find free podcast videos online.
There are numerous podcast directories online that can
help you find feeds to subscribe to, or you may find a
feed that's available from a site you enjoy. After looking
through the directories and finding a feed you want to
download, subscribe to it using one of the many free
podcast clients available. The podcast client will
automatically download a small file called an RSS file,
which stands for Really Simple Syndication. The RSS
file tells your podcast client when there is a new file, in
this case a video, to download. Depending on your
client, the program will notify you or maybe even
download it automatically. Once the file is on your
computer, you'll be free to listen to it any time it is
convenient.

Soon you'll be on your way to downloading some of the
free podcast videos available online. Feeds are available
that publish on almost every topic, from independent
news shows to experimental videos, to scientific
information. Some colleges and universities even
podcast their most popular lectures so that students will
have a chance to watch and review from the comfort of
their computer chair.

The best part is that these free podcast videos, are of
course, free. All of these feeds are easy to find, and the
publishers, for the most part, do it simply because they
enjoy it, and are glad to give it away.

Podcast News

Downloading Podcast News

With the rise of podcasting, many individuals and
organizations are finding that podcasting is a great way
to distribute information, from music and comedy
shows to talk shows, even podcast news. CNET is one
of the groups that is distributing a news podcast. CNET,
being an online technology site, naturally found a niche
distributing a tech news related podcast. CNET's recent
podcasts covered such topics as viruses that attack cell
phones, problems with Google's software, China's web
restrictions and the "Great Firewall of China", and the
FTC's attack on spyware. These news items were
distributed in a sound file called an mp3 file that is
downloadable to a listener's computer for listening
whenever they wish. While these files were available
straight from CNET's site, the majority of them are
shared through the use of an RSS file. An RSS file is a
small piece of XML coding that is downloadable by
programs designed to read it. These programs are called
podcast clients, and the user can input the address of the
RSS files that hold the information on the feed. The
feed will contain links to the media files of the podcast,
and will download the new updates automatically.

More sites than CNET are finding that podcast news is
an expoitable technology. The British Broadcasting
Corporation podcasts some of it's programs, as well as
the US radio network NPR. The NPR, because its work
is created by a variety of different groups, treats
podcasts differently from show to show. The NPR show
"This American Life" distributes a podcast of the show
through a site called audible.com, which allows feed
listeners to subscribe to the feed for a small fee and
download the show . The NPR Hourly News show, on
the other hand, shares a short 5 minute broadcast that
summarizes the news for free. Since the NPR is taking a
radio show and converting it into a file that is
downloadable by the user, little is lost in the translation.
The sound is designed to convey the entire story, and so
podcast subscribers are able to treate the podcast as
nothing more than TIVO for the radio. ABC's podcast
of the news show Nightline, on the other hand, is
simply the sound track from the television show. This
has been one of the criticisms of the Nightline podcast,
because by merely stripping the sound from what is
designed as a television show, much information is not
given to the users. Listeners have problems telling who
is who because they miss the visual cues that were
supposed to be there, and there is no truly easy way to
convert the shows. For this reason, some news shows
have been moving from audio podcasts to video ones.

Podcast Client

A Podcast Client

A podcast client is the software used to access and
download podcasts. Podcast clients are also known as
media aggregators, programs designed to automatically
access an online file, or feed, and download the audio or
video file associated with it. Hundreds of these
programs exist, with names like IpodderX, Juice,
Nimiq, and PodSpider. These podcast clients are easy to
find, and because there are so many available for free, it
is easy to find one that suits an individuals needs and
style. These programs run on the users computer,
periodically downloading a small RSS file from sites
that it has been told to monitor. The file tells the
program about an audio or video file stored on the
server, and the podcast client then downloads that file
for the user to view or listen to.

The podcast client thus allows the user to view
information on a wide range of topics from their
computer, without even using a web browser. Just like
blogs let people find writers they enjoyed for any niche
topic they were interested in, podcasts let people do
them same for audio and video. Its as if a thousands of
radio and television channels were created to serve
every possible interest, and more were made every day.
Using the podcast client to access and download the
files makes it as easy to keep up with the sites one likes
as it is to publish the feed.

Podcast Downloads



Podcast downloads are a wonderful new online way to
share files. A podcast is a way to send files from a
distributor's online site directly to the subscribers
computer, where they can view them whenever they
wish. A podcast works by having a small file called an
RSS file placed somewhere on the podcaster's web
page. This RSS file is updated regularily, usually
automatically with text and links to new media files
available for downloading. The RSS file is then
accessed by the podcast client of the subscriber's
computer. A podcast client is a small program that goes
online to look for the RSS files that the feed subscribers
wish to view. There are many podcast clients available
for every conceivable need, and most are free to
download and use.

The podcast download will be done when the podcast
client downloads and views the file from the feed's
website. After finding the links to the media files
embedded in the RSS file, it will download those files
and store them on the computer, allowing the user to
view them whenever and as many times as they wish.
The podcast files may be of many things. There are
comedy shows done by people who enjoy creating and
writing a regular show, but aren't able to do it as a
business. Some podcasts are music mixes, an mp3 file
that subscribers can play. Even some radio shows are
getting into podcasting, allowing subscribers to
download portions of their shows from the internet in
podcast form and play them on their home computer.

Podcast downloads could conceiveably be applied to
any type of file. The RSS files that allow the mainly
audio and video files now used in podcasting to be
downloaded can be customized to enclose almost any
type of file. This has led some analysts to believe that
podcasting could eventually be used to distribute
software updates, demonstration programs, and many
other types of files, moving beyond the simple use of
podcasting to share media files. All that would be
neccessary would be for the users to subscribe to the
feed with their podcast client. They could then stay
regularily updated for nearly anything.

Podcast downloads offer many different possibilities for
distribution of files across the internet. Because it is a
different mode of using the internet, allowing the data
to come to the user rather than the user having to visit
each site they enjoy, podcasting has the possibility of
changing the way the internet works. Content can be
given directly to the individual, easily and ever more
quickly as broadband use spreads. This means that what
the internet is will change drastically. The web changes
from something connected to in order to be used to
something that is integrated and connected with our
personal life.
