What
is I.V.I.N?
I.V.I.N. is an acronym for the Indiana Video Information Network.
Developed at the Indiana Department of Education in 1997,
IVIN delivers to the Internet community streaming programs
which vary in length and content. Refer to the main Program
Guide for the listing of available programs. |

In
what format does the Indiana Department of Education stream
their video?
The Indiana Department of Education uses the latest technology
to stream their video to the Internet using the RealEncoder and
RealServer. This technology includes the use of multi-rate
encoding and adaptive bandwidth delivery. Most of the videos
created are done so in multiple rates, so if you're on an Internet
connection that is very fast, you'll get a very clear picture
with stereo sound. If you happen to be on a slower Internet connection,
the picture may be pixilated -- however, you'll still be able
to watch the program. In addition, several of our programs are
offered in pristine H.323 video for iTunes and portable media
players. |

What
program should I have in order to view RealMedia files?
You must have either the free RealPlayer or the purchased
RealPlayer Plus application. The free RealPlayer can be obtained
on the IDOE web site by clicking the RealPlayer icon found
on any Program Focus page, or the IVIN home
page. Please note: the RealPlayer has a built-in method
of checking for updates. You'll find it in the menu under Help>Check
for Upgrade. Although you may be presented with a large number
of choices for the products Real offers, you only need to upgrade
when one of the selections reads "Full Upgrade". Also,
if you're planning on watching one of our live events, don't
wait until the last minute to upgrade. Depending on the time
of day and the speed of your Internet connection, it may take
several minutes to a half hour to upgrade your program. |

How
do I install the RealPlayer after downloading it to my
computer?

Whenever
I click on a link to play a RealMedia file, the RealPlayer
buffers almost the entire program. What am I doing wrong?
In the RealPlayer preferences (found in the menu) you probably
have your connection speed set too high. For example, you are
connected to the Internet at home on a 33.6 Kbps modem line.
You have the preferences in RealPlayer set at a connection
speed of T1. The RealPlayer sends a message to the RealServer
delivering the file and tells it that you are on a higher speed
line than 33.6. The server attempts to deliver a high speed
file. Since your computer is not receiving the file fast enough
to play it smoothly, it buffers the content until it can play
a reasonable amount of footage. To solve this problem, go into
the RealPlayer preferences and select the correct speed of
your Internet connection. (see below)

The
RealPlayer plays the video but I don't hear anything.
This could be due to a number of things. On a Windows machine,
make sure your computer has a sound card. On a Windows and a
Macintosh, check your speaker volume, power, and control panel
volume. |

When
I play a file, the RealPlayer gives me a message that it
is dropping the frame rate by a certain percentage due
to poor system performance or network congestion. What
does this mean and how do I correct the problem?
This means that for some reason or another your computer
just doesn't have the power to play the media file or there is
a lot of traffic on your Internet connection. 'Power' meaning
either there is not enough memory (RAM) available or you have
too many programs open at the same time. To correct this either
have more RAM installed on your computer; shut down applications
not necessary to the operation of the web, Internet, or RealPlayer;
or view the files on a more powerful computer. |

Can
I download these programs and view them offline?
Yes, with the RealPlayer Plus. All the media files have been
encoded with Selective Record enabled. This means if you have
the RealPlayer Plus, you can record the file to your hard drive
as you're watching the program. Beware, these files are greatly
compressed for delivery over the Internet yet an individual thirty
minute video file can be as large as one Gigabyte. In addition,
any program posted in our Podcast can be downloaded to your computer
for viewing at a later time. |
