How Does Satellite TV System Work?

[ad_1]

Technology seems so important today and it seems to be the best thing in our everyday life. Without the help of technology, our lives would still be like in the Stone Age. People today however tend to take technology for granted. We all know how to use it but never really understand how a device does really works. Therefore, let us take a view on how does a satellite TV system operates.

Years ago, satellite TV was only and imaginable technology that everyone could only dream of. The cost of this technology includes the huge antenna and the high maintenance cost plus the costly installation or set up fee. However, once installed, you could get TV signals no matter which part in the world you are in. This system is extremely suitable for those who live in rural areas where there are no TV coverage from traditional antennas. The normal TV signals are broadcast using radio waves. This sort of transmission travels in a straight line. Therefore, in order for you to receive the TV coverage, you must have your TV antenna positioned in a direct line with the main TV station antenna.

As for the satellite TV system, the signals are sent to the satellite. The satellite will act as a transmitter and receiver at the same time. By receiving the signal from the TV station, it transmits the signal to the dish of every subscriber. With the satellite orbiting the earth exactly 24 hours, it will be coherent with the rotation of earth around its axis. With this, the satellite allows you to view your favorite shows from your very own TV set.

It is really as simple as that. The satellite TV system is just like a normal TV receiving signals from a TV station. The only difference is that the signal is transmit via a satellite which could cover a large area instead of the normal TV transmission which only works in a direct line. Therefore, we could conclude that the satellite works as a giant reflector that could gather a signal and spread it to numerous household giving then the power to be entertainment at the comfort of their own home.

Web 2.0 And Demolition of Print Media

[ad_1]

Web 2.0 is an open source for all netizens to exercise their democratic rights without misuse. To me, the constitution of web 2.0 reads, ‘We, the people of e-space, having solemnly resolved to constitute the cyber world into sovereign, secular, democratic, republic, and to secure to all its netizens”

In plain, web 2.0 is a netizens/Internet users driven world. It has following features:

Network as platform

User driven/controlled contents

A rich, interactive, user-friendly interface based on AJAX technology

Social networking Aspects

1:1 Connection Between Mobile and Website

Any website based on web 2.0 concept has lots of scope for users. In short, democracy is the main feature of web 2.0. Thus, Web 2.0 is ‘For the People, Of the People, and By the People’.

Web 2.0 implies Netizen journalism. As web 2.0 popularizes Neitizen journalism and more people are becoming ‘public writers’, there is a fear that journalism as a distinct profession is becoming harder and harder to sustain. The boundaries between ‘professional’ and ‘amateur’ performance are breaking down

Until web 1.0, Internet was more or less treated like print media in digital form. But the technological advancement has made it possible to unleash the full potential of the Internet. Today, Internet is recognized as the most powerful medium, even more powerful than newspapers and TVs. According to a study, majority of youngsters surf Internet for a long time than sitting silently in front of the ‘Idiot Box’. Why?

  • Internet is one stop place for both motion pictures (TV) and literary texts (Newspapers)
  • Internet offers a place for 1:1 interactions
  • Internet Today offers lots of spaces for users’ to participate (web 2.0)

In short, Internet serves everything you wish for! Under these circumstances, one can never undermine the scope of Internet at time when the wave of web 2.0 is floating across. It’s high time to recognize the potential of Internet as important media, which seems to be dominating print and visual   media  ( TVs ). While TVs continue to grow at their own pace, print media (newspapers, magazines, etc.) may likely to face a tougher challenge from Internet.

I cannot predict how long newspapers will remain. But I do feel confident in predicting that the Internet will continue to demolish the printed world. And with the advent of new technologies (WEB 2.0 AJAX), creating multimedia advertisements inside web pages will make online marketing closer to the highly effective television and radio market strategy. Flash and JavaScript have added visual interactivity–and scripted database functions fill the web with more possibilities than even TV and radio.
