Streaming Audio and Video on the Internet
Entertainment is a necessity! And thank god we belong
to the digital age 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 Web casts 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
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.
