For people who live in remote or rural locations, broadcast television is often limited. The VHF and UHF signals that broadcast television emits are picked up by antenna, however remote or rural locations often are not conducive to a strong signal.

There’s the option of cable, however many of the remote or rural locations do not have access to cable television. Today, people who live in these areas have an option for quality viewing and that’s satellite TV.

Satellite TV is created through a communications satellite that is in fixed orbit above the earth. A viewer signs up with a satellite service. By paying for the satellite service they are then able to receive the satellite programming. Only those who pay for the service are able to receive the programming. Others are unable to receive it because the signal is scrambled and is not descrambled without paid authorization.

Receiving programming though satellite TV is a wireless set-up. This contributes to the quality viewing. In addition, gone are the very large dish receivers of the earlier days. These were indeed an eyesore. Today the satellite dishes are small and barely noticeable.

As with cable television, theft has been a problem with satellite television. Unauthorized people figured out ways to descramble the programming and offer it to consumers at their own prices. Today, significant improvements have been made to prevent theft of the satellite network.

Also, the descrambling features are very specific for viewers. Not all programming will come into a household. … Continue Reading ...

Look closely at the eyes of anyone ‘glued to the TV,’ and you may see zombie eyes or a spaced out expression. TV is made to grab out attention and keep it there. Everyone knows that watching TV feels relaxing. It shuts out the rest of our crazy world and allows us to retreat somewhere else. But did you know that your brain waves are actually altered when you watch TV?

Your brain actually goes into an alpha wave state – a relaxed state where you become less alert and more passive. This state is somewhat comparable to hypnosis – and it doesn’t end when you switch off the tube.

The culprit is most likely the cathode ray tubes in the TV monitor which produce a flicker that the conscious mind does not detect.

According to a Scientific American survey, “participants commonly reflect that TV has somehow absorbed or sucked out their energy, leaving them depleted. They say they have more difficulty concentrating after viewing than before.”

In the 1980’s researchers in Australia found that the left brain “sort of went to sleep” once the TV was switched on, as the right brain was busy storing information in the memory bank. As the right side of the brain is dutifully absorbing all of the images, your left brain which is responsible for critical analysis, has been lulled into a stupor. This makes analysis of what you see on TV difficult.

These studies have profound implications on watching news and other … Continue Reading ...
