Streaming Video and Audio In the Internet

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.
