Q 1. How can I view the webcast?
Beginning at 6:45 PM EDT on Saturday, October 13, you may click on the
banner on the bottom of the page at www.nws.edu. You will be directed
to a page that will ask you to sign in, providing your name and e-mail
address, neither of which will be shared or used in solicitations. Upon
pressing "submit," the webcast stream will automatically appear
on your
screen.
Q 2. What is streaming audio or video?
Streaming audio or video is sound (as on the radio) or video (as on
television) delivered over the Internet via a modem or broadband connection.
Q 3. Why is it called "streaming"?
It's called "streaming" because the sound and picture data flow in
a digital stream from a server computer to your computer, ready to hear
or view in real time, without having to download all of the content before
you can enjoy it. It comes to you in a stream of digital bits... hence
the term "streaming."
Q 4. What kinds of streaming audio or video are there?
The streaming media player used in this web cast is Windows Media Player
(Microsoft). It provides streaming media players for the Mac and
Windows platforms. The media player types vary in cross-compatibility.
The best web browser to view the stream is Internet Explorer, although
the stream is compatible with Mozilla Firefox and Safari.
Q 5. What difference does it make if content is streamed,
rather than downloaded?
Audio and video files can be very large. You would spend many minutes
or even hours waiting for them to be downloaded to your computer if they
weren't streamed. Streaming media technology allows you to see or hear
the content in just a few seconds, instead of having to wait for it.
Your only wait is a few seconds for a "buffer" to be built up that helps
avoid interruptions caused by Internet traffic problems.
Q 6. What special equipment do I need to get streaming audio
or video?
You only need modern computer with a Web connection plus player software
that can receive and process audio/video streams. You probably have the
players already on your computer.
Q 7. How can I tell if I have everything I need?
Most recent computers will have everything needed. If you have
speakers/earphones for your computer and you've heard them play sound,
chances are you're okay. The faster your online connection (modem,
cable, DSL) and computer speed (in megahertz), the higher the quality
of
the streaming audio or video will be. A minimum connection of 300kbps
is
necessary in order to properly view the webcast.
Q 8. What are media players? Do I have one?
A media player is a special type of software that recognizes the
stream coming into your computer and displays the video on your screen
or plays audio through your speakers or headphones. There are three
different formats of media players that are most commonly used: Adobe
Flash, RealPlayer and Windows Media. Your computer may or may not have
one of them already installed.
Q 9. Is it possible to record streaming audio?
If it is allowed it's possible, however this web cast is restricted.
Q 10. Is there any downside to streaming?
There are some potential problems, but we'll tell you how to avoid
or minimize them.
(1) Traffic jams. Streaming requires an Internet connection that's free
of bottlenecks or "traffic jams." But the Internet isn't a direct pipeline
from the source to you. Streamed content passes through many other computers
on its way to your computer via your ISP (Internet Service Provider). If
any one of them is carrying too much traffic, the streamed content may
be interrupted and pause. Streamed content is "buffered" to help avoid
this, but sometimes it's unavoidable. Usually the delay only lasts a
few seconds, and the audio picks up where it stopped. Video is more sensitive
to such interruptions.
(2) A slow computer. Even with a fast computer, if you have too many applications
open, it could slow down your media streaming. If you notice things are
sluggish, close all unnecessary applications and windows running on your
computer. Just keep your Web browser and your media player open. (If you're
just listening or watching, you can even close your browser.) In any case,
speedy computers (at least 400 Mhz or higher) are best.
Q 11. What if I am using QuickTime to view the webcast?
To view this stream using QuickTime, you will need to
download the free plug-in for QuickTime, which is
available by clicking
