Streaming Video and Audio In the
Internet
Author: Lester John M.

Entertainment is a necessity! And thank god we belong to
the
digitalage when almost all our needs are readily available
right in
the comforts of our own home.
And now that the Internet is here, the focus is not merely on
the
issue of merely supplying information to the users but giving
them
the choice to pick only the kind of information they are
most
interested in, when to obtain these information, where to
extract
these information from and of how these preferred
information
should take form.
Imagine using your computer in watching your favorite NBA
match,
your watch your favorite television show or the evening
newscast and
listen to the live concerts and Webcasts through Castdial.
Imagine
just sitting in front of your computer screen while searching
for
articles on the hottest political issues rather than going
through
those pile of newspapers or magazine archives in your local
library.
Streaming media is a technique that allows users to view audio
and
video contents while they are still receiving it. Or as
others
perceive it, an audio and video file that plays as instantly on
a
text based content as when a Web page downloads on your
browser.
And unlike downloading a video or audio file to be played
later, it
flows to your computer screen enabling you to view its
contents
simultaneous to the process of downloading.
So, how do you stream something into the Internet? Especially
video?
Here are the basic steps:
First, in order to stream a data in video form, a person must
use a
30-frames-per-second analog video that is fed by a VCH or
video
camera to a video board within the computer. This must then
be
converted from an analog wave form into binary data. This
representation is stored in the computer hard disk and
further
reduced in size by video compression software. The video
compression software then scans each of the frames of the video
file
and distinguishes which are redundant. The redundant ones are
erased.
Only needed data are retained.
A user can then watch a file by clicking on an HTML tag
embedded in
a website. When he does this the video streaming software on
the
remote server is released and a steady stream of data begins
to
flow. But before he gets to watch this, he must have an
interface or
a "player" installed in his computer. If he has this, he can
then
watch the file he requested through the website's remote
server.
Then comes the issue of speed of data retrievals in connection
to
bandwidth.
The snail's pace of the 28.8, 33.6 and 56 kbps modems simply
cannot
deliver the amount of kilobytes that streaming media demands.
This
situation provided the Vendors who are well aware of the
problems
to intelligently devise ways to manage network resources for
users
faced with streaming media flood. From the snail- blazing 28.8
dial-up
connections, there came much advancement. The 33.6 and 56K
variants
came out as minor upgrades to their 28.8 sibling. This
development
could be hardly felt by the users so they had to come out of
that
medium of connection—the analog modem. Then came what they
would
call the second generation of connection devices designed to
give
the subscribers a leap from 28.8 kbps to a stunning speed of up
to 1.5
mbps. What could these technical numbers signify then? Well,
it
means that the new connection speeds that subscribers could now
enjoy
could reach up to 20 or even 50 times faster than when they
were using
the 56K connection speed.
The efforts to battle bandwidth problems have produced good
results
especially in subduing qualms about supporting streaming
media
applications. By this, followed the advent of streaming
technologies to deliver audio, video and animation into
websites,
which is considered an appropriate response to this TV
generation's
insatiable demands.
Now that streaming media is gaining much recognition in the
Internet, websites are now transforming plain information
exchange in
the Internet to the ultimate sensory experience. And it is
the
consumers benefiting from these technologies. Entertainment
companies
have extended their broadcasts to the net thus expanding the
markets
across the barriers of the traditional transmitters to the
global
community in the Internet. Through innovations that
supported
streaming media, thousands of audio and video information are
now
available on the Internet. Only the users' individual
preferences
are considered their limit. Thanks to the many innovations and
new
gizmos that pop out every minute that ticks. Five to seven
years
ago, streaming media was just a young idea being cooked up on
the
Internet and now, the attention and respect for it is
increasing.
People find more reasons on why these streaming media will
slowly
shape and influence the way they see and access
information.
