Digital Technology: TV’s Next Step
Digital technology is a recent innovation to sweep through America. It has already become the standard for music purchases, and with the use of DVDs, it is now the preferred way to watch a movie in the home. Cell phones were once primarily analog, but now most service areas are digital. These changes came from the market place wanting better sound, picture, and more reliable signals. This is in stark contrast to television, because its change from analog to digital has been brought on by the FCC enacting regulations. The market place should be excited and the change, but not just for better picture quality. Though the FCC may be forcing the change in television, the market place should embrace the changes and even be excited about them.
Picture quality is not the only difference between digital and analog television. The FCC has several reasons to switch to digital. A digital signal offers better sound than an analog signal. With analog, you are only able to get two channels of sound. Digital offers you the same 5.1 channels of digital surround sound you hear in movie theatres. The combination of better sound and picture is enough to make many want to upgrade, but there are more reasons.
Digital television also allows for more bandwidth with the use of MPEG-2 technology. This is a way of compressing the information and using less bandwidth. It can reduce the number of bits by about 55 to 1, allowing more space on the spectrum. The practical use of this is multicasting. Although how this will be used is still to be determined. It is likely networks will run multiple programs in standard format during the day and use HDTV during primetime.
Naturally, both analog and digital signals lose strength over long distances. With analog signals, this causes a horrible picture filled with static. This differs drastically with a digital signal. The signal still weakens over distance, but it makes no difference in quality of picture or sound. As long as the television receives the signal, no matter how weak it is, the picture and sound will be clear. Obviously, this could be a potential problem for cable and satellite providers. Many consumers will no longer have to pay monthly fees to have an acceptable picture.
A TV signal is captured by a camera and then manipulated during program production. At this point the video must be at its highest quality and full bandwidth for recording, editing and special effects purposes. Then the TV signal needs to be compressed for economical transmission and storage. The possible efficiency of compression depends on a couple of factors. If a signal will be further edited and manipulated in the receiving studio it must maintain a relatively high quality and therefore can’t be compressed as much as a signal that will be sent directly to the viewer’s TV set. Also, the extent to which a signal can be successfully compressed depends on the type of program (E.g. movies can be compressed more than sports). Nevertheless, a typical program mix will fit up to 10 digital television channels on one transmission line.
During the sixteenth century and even into the seventeenth century, scientific discoveries and new empirical ways of thinking began to emerge. This period of history is commonly referred to as the Scientific Revolution. The Scientific Revolution challenged past authorities by challenging church teachings, philosophy, and traditionally held views of humanity’s place in the cosmos.
Milton Friedman is one of the well-known America economist that success in the field of economics. He was born on 31st July 1912 in Brooklyn, New York, United State of America and died of heart failure on 16th November 2006 at the age of 94 in San Francisco, California, United State of America. Milton Friedman has three elder sister and he is the fourth and last child and first son of Jeno Saul Friedman and Sarah Ethel, both of whom worked as dry goods merchants. His height is about 152 centimetres. His spouse is Rose Friedman who was born on year 1938 and died on year 2009 at the age of 71. Milton Friedman has two children, David D. Friedman, an anarcho-capitalist economist born on 12nd February 1945 and Janet. Patri Friedman, his grandson was the executive director of The Sea steading institute from year 2008 to 2011.
...rom broadcast media also heralds an opportunity. In a world of self-service digital, where consumers compare everything according to value, online video is the ultimate table stakes. For mere pennies a day, consumers can get the content they want (that’s key) when they want it on whatever device they are using. They can watch their shows on their time from the mobile phone or a tablet or a computer or a smartTV. And that is the ultimate value for whatever it costs. Perhaps broadcast media can figure it all out in time. Perhaps they can stave off Judgment Day by evolving their business models to provide the kind of value consumers want. Then they become just another online video provider competing for the same eyeballs as everyone else. Changing their business model (away from subscriptions) would require Herculean efforts.

The digital evolution began to transpire on November 1, 1998. Since then there have been many other forms of digital technology adopted by our society and digital television quite possibly is next. “The speedy conversion to digital technology will have profound interest benefits, permitting efficient spectrum use, optimizing the development of new technologies and services to consumers, and fostering diversity and competition(FCC).
As Europe began to move out of the Renaissance, it brought with it many of the beliefs of that era. The continent now carried a questioning spirit and was eager for more to study and learn. Throughout the sixteenth and seventeenth centuries, many discoveries were made in subjects all across the realm of science, but it was the doubting and testing of old traditions and authorities that truly made this time into a revolution. The Scientific Revolution challenged the authority of the past by changing the view of nature from a mysterious entity to a study of mathematics, looking to scientific research instead of the Church, and teaching that there was much knowledge of science left to be discovered.
When you think of digital signal processing, what comes to mind? Well you may think digital signals, so cell-phones? What about radio’s or even satellite television? The answer is yes, all these are correct, but there is a broader impact of digital signal processing that goes beyond these everyday items. Digital signal has been around for about 5 decades, starting back in the early 1970’s [4]. Analog has

The revolution brought about many radical changes and ideas that helped to strengthen it and the scientists that helped to bring it about became significant persons in history. "The emergence of a scientific community is one of the distinguishing marks of the Scientific Revolution."2 It was this form of community that gave a foundation for open thinking and observing throughout the sixteenth century and through twenty-first century. It was the first revolution that had more of a dedication to the ongoing process of science than of a goal to achieve scientific knowledge.3
... viewing quality becomes and the more channels we can get, the more people are likely to stay inside. Don’t get me wrong, I love TV, and I feel that it is one of the most important inventions that this world has been blessed with; but I feel that it is taking away from some of the “realness” of our lives. People are becoming less healthy, they are developing eye and other health problems, and they don’t know what is real and what is not any more. I hope that in the future television designers and makers can develop so new technologies that would improve and not worsen our environment. The television is a very helpful and important tool that has had a great impact on our society, but we need to be aware of how this tool has also affected out environment as well, so next time you watch you television, think about what impact you might be having on our environment!

In conclusion, the scientific revolution brought dramatic change in the way people lived their lives, and it certainly influenced eighteenth century free-thinking. The scientific method was comprehensively utilized during the eighteenth century to study human behavior and societies. It enabled scientist and scholars alike to exercise their freedom of rationality so they could come to their own conclusions about religion and humanity as a whole. They could finally do so without having to defer to the dictates of established authorities.
