How a Television Works
The job of a TV set is to turn the electronic signals created by TV
cameras and microphones back into pictures and sound. The TV's aerial
picks up the signals from the transmitting studios and they then
travel down a cable to the aerial socket at the back of the TV. When
you switch on the set, the sound and picture signals are separated
from each other and from the carrier waves. (The TV signal on its own
isn't powerful enough to travel very far so it is mixed with the much
more powerful carrier wave and can then travel much larger distances.)
The sound is then sent to the TV's loudspeaker. The picture signal is
split into three separate colour signals; red, blue and green. If you
look closely at a television screen you can see that the picture is
made up of lots of horizontal lines. These lines are made up of tiny
dots which glow red, blue or green. Your eye has three types of
detectors - called cones - that react to these colours differently.
There's a red cone that likes red light, a green cone that likes green
light and a blue cone that likes blue light. When any colour enters
your eye and hits these cones they send messages to your brain saying
"I'm seeing red light" or "I'm seeing green light" or eve "I'm seeing
a bit of blue and a bit of green". When the light from the dots on the
television screen enters your eye, each cone sees each colour and
sends a signal to your brain. Your brain then works out what colour it
is supposed to be seeing from these signals. The screen itself is part
of something called the picture tube. At the back of the picture tube
are three electron guns (that fire electrons rather than bullets!) one
for each colour. The electrons are shot out of the gun and hit the
screen. These dots are made of phosphor, which glows when electrons
hit it, the stronger the beam of electrons the brighter the glow.
...on and bring pleasure in the form of entertainment. Even though television, a technology that produce moving picture and current events affected the lives of America from 1930s to 1960s. They found a way to recuperate by minimizing the use of television and maximizing the use of the outside world.
Readability of text: The grade level I chose is fifth, and the material comes from McGraw-Hill’s Reading Wonders. “The Boy Who Invented TV” by Kathleen Krull and illustrated by Greg Couch is the text I used to apply Fry’s Readability Formula. The Lexile Text Complexity Range is set at 860 and the Text Evaluator is at 38 for this particular story. “The Boy Who Invented TV” was an appropriate biography for fifth grade, however I was surprised to use the Fry’s Readability Formula and find that it was actually graphed at an upper seventh grade level. After doing this readability I have a newfound understanding as to why students, especially lower level, can really struggle with the text found in their books. It is much more evident that after reading
Before television existed people had to depend on Radio stations to receive their little bit of entertainment and news. But in 1878, the invention of TV began. The first TV made didn’t look anything like the way TV’s look today. It was a mechanical camera with a large spinning disc attached to it (Kids Work). But as over the years, of course, inventions of different TV’s progressed and by the 20th century about 90 percent of our population had a TV in their household (MGHR). Television today is mainly used for people take a break from their life by relaxing and enjoying some entertainment.
The Television Decoder Circuitry Act of 19903 required all new televisions sold in the United States to contain a chip to decode closed-captioning4 signals. The basic technology needed to implement the V-chip is the same as that currently used for closed-captioning.
As similar their names might sound, a television is not like a telephone. A telephone connects two people's minds to each other, while a television only sends pictures and sounds to one person's eyes and ears. In fact, if you let television affect your mind too much, it can cripple your imagination. You might have more images stored in your mind, but you will be out of practice for generating new ideas. Television does not provoke original thought.
Adams, Guy. “Is your TV spying on YOU? It sounds like science fiction but many new TVs can watch you- telling advertisers your favorite shows or even filming you on the sofa. And there’s no off switch!” Mail Online. (25 Nov 2013). Web.30 Mar .2014.
TV show the essence of a what a TV is in the manner of what it means to be a TV in this day in age. The TV in it self is not just the glass, plastic and metal in their separate forms but once brought together with the Idea of a traditional TV set. Where the glass is used to show an imagine on the screen and the plastic as a way to keep the metal components unexposed. The Efficient cause, this refers to the reason behind something’s existence. In the example, a TV exists because someone had the idea to build one and put all the parts together to make it
Over the last forty to fifty years, television has been a major topic of discussion. Specifically, many debate societal benefits to television watching. One widely accepted opinion is that watching TV makes people dumber. People have referred to it with terms like the “idiot box” and do not feel that watching TV has any benefit at all. They feel that it is a waste of time and people need to spend their hours more wisely. Others are of the opinion that TV is actually has societal benefits. From this perspective, they claim that the development of the structure of the programs now requires one to intellectually participate in watching television. Essentially, the argument is whether TV is a beneficial societal force or is it simply a convenient, yet detrimental, outlet for entertainment.
Factors that Shaped the Invention and Development of Television in the UK Up to 1939
Overall there are many advantages to digital television. The point to creating digital television is to receive digitally encoded broadcasts. These digital broadcasts are more picture perfect and have more lifelike sound than analog television. In an analog system the waves are modulated into mechanical form and transmitted through air or over cable. In a digital system sound and images are analyzed first then converted into a stream of numbers. Digitized information is transmitted in this system, not mechanical waves(Johnson).
Many Americans today go home and flip on the television, but many do not take the time to think about the complexity of this great invention that is common to us. Nearly sixty years ago television barely existed and was not thought to be used as a broad communicator like it is used in today’s generation. Through its starting, stopping, then restarting in the 1940’s, television took off and expanded greatly in just a few short decades and had great technological breakthroughs to allow it a widespread range of uses. Though technologies existed in the forties, the great advancement and possibility that television would have, were not yet explored. Just as the radio, television was a process being experimented with, worked, and transformed into a sufficient idea. What was television for in the early 1940’s? How was it used? How did it progress into the 1960’s? What great advancements that took place between the two decades? These are questions many people may think of, but never quite get the answer to how we got the great television advancement we have today.

As stated by Alex Zambelli, 2014 “To the generation of children being born now, flipping TV channels will one day seem as foreign as rotary phone dialling”. Based on the quote above, it has come to an understanding that technology may develop into a new medium. Jenkins (2006) argues, “digital revolution presumed that the outcome of technological change was more or less inevitable.” This implies that technology will continue to be more advance and it is unavoidable. In example, some of the changes can be seen from hand phones to smart phones and desktops to laptops or tablets. This does show that technological change is inevitable, as technology will continue to be more advance because of competitors and inventors. This paper focuses on the
