Open Spectrum Bidding For Internet Usage

The government is trying to spread the word that in 2009, all television signals that are transmitted through the air are going to be terminated. All television signals at that time will be digital. When that happens, there will be an open section of the spectrum used to transmit all types of information through the air. Companies like Google are already trying to bid on some of these frequencies.

As of right now, the Internet is a big part of our lives, and that part may get even bigger. We can access the World Wide Web through our service providers, and some home phone services are now going through the Internet. A majority of these signals go through lines and wires, but some of it is going through the air. More space on the spectrum opening up could mean even more of these signals would be going through the frequencies of this spectrum.

If these frequencies are bought up or leased exclusively to private companies, prices could go up in some cases. There are some that would like to see an open spectrum that could be used by anyone willing to follow specific regulations on how to use it. For the consumer, an open spectrum could mean free use for telephone calls, or for Internet access that could reach almost any home within the United States.

Some politicians believe that an open spectrum would mean that more information could be freely shared, and that would be for the benefit of anyone with a way to access the Internet. With the freeing of frequencies coming up within the next year, people can only guess what is going to happen. Should Google buy up a large percentage of this open spectrum, the free access may not happen. However, that might just be what they have in mind.

Whatever happens, remember that phone calls are going through those Internet connections, and there may be more and more of these numbers should that spectrum open for free use.

The History of Scented Candles

Not many people seem to know this… By the end of 2012 the UK will have been the only country in the world to have totally made the switchover to all digital television. The digital switchover starts in 2008 – less than 2 short years away.

A recent Which Report (Which is the major consumer champion in the UK) shows that in many areas the awareness of the digital switchover is less than 2 %. Even in the Borders Television region – the first to make the change – only about a third of the people surveyed knew what was going to happen.

It really does seem that the UK is sleepwalking in to the Digital Switchover.

Not surprisingly, the whole switchover programme is being watched with keen interest by other nations around the World. The benefits of digital television for broadcasters, manufacturers and programme makers are pretty clear. The new media is already changing programme making – Planet Earth, currently showing on the BBC – is a prime example of what can be achieved. And of course the manufacturers are positively drooling at the thought of all the new televisions, video recorders and set-top boxes they expect to sell.

Consumers are set to benefit too – better pictures and sound, high definition television, interactivity, movies on demand… The list goes on.
Governments have a keen commercial interest too. They own the air waves. And digital television takes up much less band width than conventional analogue signals. So the move to digital frees up precious broadcasting capacity that Governments are keen to sell to the highest bidders. The sale of the mobile telephone spectrum for 3G providers raised over £20 billion. Who would bet that the sale of the television spectrum won’t raise significantly more?

The move to digital television benefits us all. So why do so few people know what is happening?

Simply being able to receive digital television is only part of the issue. Just about every television bought more than 12 months ago, and a good percentage of those being sold now, are effectively obsolete. All of them will need a separate satellite receiver or set top decoder box to receive digital signals. Every video recorder will also need an additional decoder.

The UK Government puts the average cost per household to upgrade to digital television at £132 ($210). I feel the real figure is likely to be 4 or times this level. Most homes in the UK have upwards of 4 televisions – each and every one will need significant investment to receive digital television signals.

In the UK 68% of homes already receive digital television in some form- satellite (which means BSkyB – the only UK satellite television provider), cable or terrestrial freeview. In almost all cases digital television is only watched on the main television in the house. The other sets are still restricted to the main analogue, terrestrial stations. From 2008 this has all got to change.

It’s time to wake up. We are at the threshold of the biggest change in the television experience since it was first invented.

Using Spectrum Graphic Analyzer to Help Those In Need

Color blindness is something that can happen at a young age or later on develops as the person ages. Someone who has this deficiency will not be able to distinguish one color from another or may not be able to see an image clearly on a background.

This could be genetic or is caused by an injury in the optic nerve or retina. The person may not be able to distinguish between red and green in the beginning or blue from yellow and studies have shown that this can get worse over time.

However, there are more patients who get this deficiency because of heredity and it happens more often to men than women. Some people may be partial meaning, the individual will not be able to discern some colors while this could be complete for others but such cases are very rare.

The part of the eye that allows people to distinguish one color from the other is the photoreceptor. Those who don’t have problems identifying the pigments are known as trichromats while those that do are called anomalous trichromats.

Color blindness also affects how someone sees a graphic image. A normal person may see a number in the background while those who have this problem don’t. The sad part is that there is still no treatment or cure for this deficiency.

Since many only suffer from mild symptoms of this problem, scientists have come up with a way to make this work. This is done by using a spectrum graphic analyzer that can aid the person in seeing things better.

The first thing this machine will do is transform more than 16 million colors into a smaller figure to about 256. This is also used in graphic pictures on television and any other object that the person sees.

Then, the individual will have to learn the colors and in time get to see an object more or less the way someone with normal vision can.

This device is the first step of many that will be taken to help those who are suffering from color blindness. Hopefully a surgical procedure can be developed just like how doctors are able to help patients with cataracts see again.

Spectrum graphic analyzers are not only used to help patients who are color blind. This is also used to record video and audio. The individual can download this into the computer and then review the recorded footage.
