The Awesome Digital Television

Intro

 

Have you ever, wondered why is Digital Television better than analog TV? Also, why hasn’t DTV come out in stores yet? Maybe you’ve wondered what is DTV? Another good question is why do we have to switch from analog TV to DTV? There are many questions about the interesting DTV that my report will answer.

What is DTV?

 

This paragraph is about what DTV is. According to 2007 DTVansweres, “DTV is a type of broadcasting technology that has crystal-clear pictures and sound, and more channels then ever before. The benefits of DTV are remarkable, millions of public citicins risk losing television reception unless they take the easy steps to receive a digital signal.”

What do you need for DTV to work?

   

This paragraph is about what equipment requires for DTV to work. A popular question is do you need to buy a whole new TV to work? The answer is no. Analog TV used to use antennas to get a signal. The signal would come through the antenna and straight to the TV screen. Now in order for DTV to work all you need is a DTV converter or else you won’t be able to see anything except for maybe static.

What’s so great about DTV?

 


This paragraph is the qualities a DTV has. According to Marshall Brain, “the DTV has extra image area, better surround sound, and better picture. On DTV you’re able o broadcast to the police about emergencies. A break in at your house would be a great thing to broadcast to the police. Also, DTV has more pixels and the more pixels you have, the better picture. More pixels are better because there’s more detail in the picture.”

 


The switch to DTV

 

This paragraph is about why DTV hasn’t come out yet.

According to Kim Hart and Pete Whoriskey, “America's switch to DTV has taken more than two years to make. The government has spent over $2 billion making DTV. Broadcasts spent another $1.2 billion to run waning ads and millions more to upgrade equipment. Until last week, the United States seemed ready to follow the 6 European countries that have made the switch.”

 

 

This paragraph is about why we need to switch to DTV. According to Tom Harris, “Analog TV signals consist of vibrating electronic waves. Every detail in the picture is made by vibration. The more detail you have, the more of the vibrations it must make. There is a limit to how many vibrations you can pack into a 6 MHz TV channel, which explains why HDTV cannot fit into normal analog TV. Analog TV has other problems too. Little errors creep into the signal causing the colors to shift. Noise and other interference mixes with the signal causing the picture to become grainy. When it is snowy the signal becomes week. When the signal bounces off buildings and mountains, the reflected signal gets in the way of the original signal. When the signal gets recorded and played back, imperfections machinery degrades the picture even more. The invention of DTV answers many of these problems. Video's vibrating wave is electronically sliced into billions of tiny slivers, each sliver is converted into a number, and from then on, only numbers are transmitted, recorded, and manipulated by the equipment. Interference, noise and machine errors could make those fuzzy.”

 

Analog TV

       This paragraph is about what analog TV is. First of all analog TV is the TV that we have today. According to Marshall Brain, Analog TV is the technology that has been used for U.S. television broadcasts since the 1940s. TV stations are currently making the transition to digital broadcasts.

Conclusion

 

Thank you for reading my report on the awesome DTV! DTV is Digital Television that has better sound and picture. We need to switch because the signal of analog TV isn’t working out very well. Remember, you don’t need to get a whole new television set for DTV. All you need is a DTV converter.
