Why Do We Need Cable TV Today?

[ad_1]

During our younger years, we are educated by our parents about the needs and wants. If you really forgot about the meaning of both needs and wants, we will try to review this for our future and existing customers or subscribers in the world of cable television. When we speak of the need, it is something that you give importance to a person, thing or anything that surrounds you. Some of the good examples of a need are food, clothing, shelter, education and medicine. These are very common for all kinds of customers or subscribers around the world.

On the other hand, a want is something that has no importance or purpose to a person, place, or thing. In this way, you are giving or obtaining an item that is not really important in your daily life. A good example for this situation would be a Sony PSP. It is a portable gaming platform that allows you to play games in a real high quality mode. You can play any time you want, but it’s not that important. It is considered as a want, because it is not really needed for your daily life. However, we need something that can make a living for ourselves.

Food and drinks can make a living for all of us. It is considered to be our body’s energy source, and it fuels our way to live. Without them, we will not live longer. Now we know about the different needs and wants in our daily lives, let’s try to relate this with cable TV. There are customers who think that cable or satellite TV is a need, while others say it’s a want. Why do we need cable TV for the customers and subscribers? First of all, cable TV is an appliance that gives us pure entertainment at home or any place we want to watch TV.

There are lots of reasons that cable or satellite TV is considered a need, and there’s no question about it. The first reason would be pure entertainment. Everybody loves to be entertained, especially at home. It is also good for those who are stressful at their workplace. If you work around the clock for 8 hours a day, stress will arrive after work. We understand that being a stressful person is not healthy, and we need something to get you out of stress. Cable television is one of the reasons that a customer or subscriber is free from stress.

It gives them a lot of fun and relaxation in watching their favorite TV shows at home. Best of all, it is considered to be an alternative medicine of boredom. Speaking of boredom, it is one reason that customers or subscribers need cable or satellite television for good. Aside from being stressful, cable or satellite television will get you out from boredom. It is really sad that you always feel bored at home, doing nothing for a cause. This is where customers or subscribers are trying to get their hands on a cable or satellite TV to give them non-stop entertainment at home.

LCD vs. DLP TVs

[ad_1]

Two new technologies in the world of TV, DLP and LCD, are now in a tight competition. Not long ago, everyone was talking about Plasma and LCD – which one would win? It became clear to most that Plasma, with its short lifespan of just 3-4 years, was simply not the best choice. In fact, the LCD screen has several benefits over plasma. For instance, LCD screens run much cooler than the average plasma TV, and thus require less power to operate. Plasma TVs run so hot, in fact, that they require a fan to cool them down – which can be noisy. In addition, plasma screens have a tendency to degrade over time, slowly becoming dimmer. LCD screens, on the other hand, run relatively cool, and do not degrade over time. Some Plasma owners, who have used their TVs for a few years now, have already witnessed the dimming of their screens. Also, LCD screens tend to have overall better picture quality, and are typically 10 to 15 percent lighter than plasma.

Now the choice is mainly between LCD and DLP – two distinct technologies that offer slight differences in display, price, and performance. If you are looking to buy a new flatscreen TV this year, you are probably wondering which one is right for you.

What are DLP, LCD TV Screens?

DLP stands for Digital Light Processing, while LCD stands for Liquid Crystal Display. DLP technology, developed by Texas Instruments, uses a DMD, or Digital Micromirror Device, contructed of 1.3 million microscopic mirrors. Each of these mirrors is essentially a single pixel. When a digital signal enters the DLP system, each mirror is either activated or not, resulting in tapestry of mirrors tilting either towards the DLP light source or away. This process produces different levels of light and dark reflected by each individual mirror. The colors are produced when the DLP light sources run through a red, green, and blue color filter on a moving wheel. Depending on the lightness/ darkness of each mirror, the colors come in an enormous amount of shades, producing vivid color images.

LCD screens are made of several polarized glass panels, between which are liquid crystal molecules. An electric current is run through the crystal molecules, changing their position in respect to the glass. As light passes through the molecules, these changes in angle result in different lightness/ darkness patterns that produce images on the screen. There are usually three polarized glass panels, one with red pixels, blue, and green. This system also produced very accurate, vivid images, but angle is important. You may notice that the best colors in an LCD display are seen straight-on.

Is DLP, LCD TV Screens better than the other?

Simply put, that is a difficult question to answer. Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contrast, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over the last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you’ll want to remember that in order for you to get the best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is the best investment, at least for the next few years.

Everything Needed To Know About Satellite TV

[ad_1]

Similar to cellular telephones, many people around the world use Satellite TV. For some people, this is the only way to receive television signals, but for others it is simply a way to view more television channels than what standard cable providers provide. There are television providers in Japan, Europe, South America, and basically all over the world.

Satellite TV has existed since the 1960s, though it did not become popular until later when it became more accessible. The first TV company was in the Soviet Union, however it did not send TV signals directly into homes until 1976. Until then, there was a central antenna that received the signal and the signal was sent out to the homes of the people. This new technology did not appear in North America until some years later, but has now become extremely popular.

Direct broadcast is the mode that is typically used today, which is not the same as the earlier version. This direct broadcast is where the individual has his or her own satellite antenna and receives a signal that goes straight to his or her television. Today, signals are digital as opposed to analog, which means more or less, they are able to be broadcast at a higher frequency.

Typically, due to the laws of physics, a higher frequency wave will travel a shorter distance. This higher frequency often translates to better quality whether the medium is radio, television, or internet. However, because digital signals are better quality than analog signals, it is now possible for satellite TV to be broadcast in digital.

Currently, there are two major providers in the United States. These providers offer anywhere from 250 to 1000 channels. They charge for their service based on a series of packages, which are groups of channels. Typically, if the customer wants more channels, he or she will have to pay extra. Most of the time, there is a basic group of channels that the company deemed most customers would want, and then each subsequent package will have more channels. Most packages are a mix of sports, news, movie, and educational channels.

In recent years, HD television has become popular, and therefore, most providers offer High Definition service. This typically requires a larger antenna and a special high definition television, However, in many countries these are becoming cheaper and more accessible to the public.

The technology is being improved every day. Through technological innovations that allow the interaction between television and internet it will be possible, and is in some cases, to use the internet with the equipment provided for the satellite TV. It is already possible in many instances to listen to digital music with the satellite equipment.

It is thought that this form of television may not as disruptive to the environment, since to broadcast to homes, there does not need to be a wire connected from the home to the television provider. For people in more remote locations, where the cable companies cannot provide the wire connection, this may be their only option.
