Satellite is often considered one of the biggest improvements in broadcasting since the introduction of the FM band. Satellite radio is also called subscription radio or pay-radio because it is only available trough subscription to one of the satellite radio providing companies.

Satellite follows a concept similar to cable television by providing a very wide range of programs which are not available in the traditional FM or AM format for a fee.

Satellite uses satellites to deliver radio programs to subscribers. The radio signal is broadcasted from Earth based stations to communicational satellites, which then redirect the signal to satellite radio receivers. The radio signal is broadcasted by communication satellites to a much larger area than traditional terrestrial radio antennas.

For example, satellite is available al across the continental area of the United States. Satellite radio is available now in most parts of the world trough services provided by companies like WorldSpace (in Europe, Asia and Africa), Sirius and XM Radio (in North America).

The signal you receive using satellite radio is digital, which means that it is always clear and static-free, which is one of the great advantages of satellite radio. Another great thing about satellite is that it is almost completely commercial-free.

To begin listening to satellite radio you will need the actual satellite (also known as tuner or receiver), a satellite antenna (which is often incorporated in the satellite radio) and a subscription to the service you choose. There are several types of satellite from which you can choose.

One of them is the dedicated car or home radio, which play trough your car or home stereo. A second option is the plug-and-play radio, which can be used in your car, as well as in your home by paying a single subscription. Your third option is the portable radio, which has rechargeable battery, a built-in antenna and you can listen to it wherever you go using headphones.

The signals offered by different satellite radio companies are proprietary, which means that you will need different hardware for receiving, decoding and playback, depending on your subscription. Each satellite receiver has its own serial number called Radio ID.

When you get your subscription, you will also get an activation code for your receiver. Besides the actual radio programs, satellite transmits metadata that contains the name of the artist, the title of the song or program, as well as the name of the channel. This makes it easier for you to decide which channel to listen to and which program to choose.

Satellite radio services provide the subscriber with more than 100 programs that vary in content from rock and jazz to rap and classical music. But satellite utility reaches far beyond listening to your favorite music without the interruption of those annoying commercials.

Satellite also offers exclusive sports programs, cultural and educational shows, news and talk-shows. Some of the celebrities that have moved their shows from free radio to satellite radio include Howard Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike terrestrial radio, satellite is not affected by bad weather or even calamities.

At first, many people wondered why they should pay for radio if they can get it free. However, satellite radio attracts more and more people every year due to its great advantages: no commercials, extensive reach, theme programs and exceptional quality of sound.

If you’re like me, I can’t seem to do anything just one thing at a time. I have to be able to do multiple things all the time and that includes watching sports events. Watching one sports event at a time just doesn’t work for me, I want to watch multiple sports events and Satellite Sports TV with the right TV makes it easy.

Using either a split screen picture, picture-in-picture (PIP), or multiple televisions you can watch several sports events at the same time. In the world of sports, this is really great because you can watch different sports events at the same time and then be able to switch between the sports events to watch the one with the action at the moment.

Today watching several sports events at the same time is a very simple process. To setup your own sports theater, you need a satellite TV receiver with multiple sports channels and a TV setup to display multiple sports channels. Satellite TV Sports allow you to have multiple sports programs on the same TV or separate TV’s at the same time.

If you want more than two sports programs at once, Sports Satellite TV also has packages where you can add additional TV’s, up to four per dish, onto one satellite system. This means you can be watching four different sports programs at once. Being able to watch four sports events continuously can really make you a sports authority. Being a sports authority means you can talk sports with anybody and having seen the sports event you will know what is actually happening.

Without a huge amount of money, you can watch up to four sports programs at the same time and do it within a reasonable budget. There are several different ways you can watch multiple sports programs.

One is using several TV’s and the correct satellite TV receiver to watch two to four sports channels at the same time. Satellite TV providers have receivers that will do either two TV’s or split screen of two channels on the same TV. Using this kind of satellite receiver, you can use a big screen TV to do side-by-side split screen or use multiple smaller TV’s to watch different receiver channels at the same time.

So, if you really want to be “The Sports Authority” and get all the sports events that you can handle, then going with satellite and multiple TV images is really the way to go. The two main things to look at are the TV’s and satellite TV receiver being used. Dish network provides several options including a high-definition DVR system that allows you to do split-screen automatically from the unit itself. This means using your existing TV, you can watch different sports events right on the screen at the same time.

If you want to have more sports, you can use separate receivers and multiple TV’s to get up to four sports events from one satellite dish. TV’s like the Mitsubishi 65 inch big-screen allow you to have split screen right on the television in a native mode. This means you can have multiple satellite inputs viewed on two screens and switch between sports events on the two sides. By setting up favorites on your satellite remote, you can then quickly flip between different sports events on each one of the split-screen sides.

To get even more events you can either add additional TV’s or get a different kind of TV that handles what is known as picture-in-picture. This will allow you to have multiple sports events on the screen at the same time. These TV’s tend to cost a bit more money and some models are a little problematic. So be careful with which TV’s you select for this particular methodology, but it can be great for watching multiple sports events.

The lesser expensive method is to simply pick up some low-end TV’s to use as side monitors and have your main television showing the sports program you want to watch at the moment. Use the side TV’s to monitor other sports programs on different receivers and switch to the sports event with action on the main TV when you see it happening on one of the monitors.

Using satellite TV receivers and a few TV’s, you can have a home Sports Theater that will make you “The Sports Authority”. So put your Sports Theater together now and start having those sports parties with all your friends.

The date has been set for the first Digital TV switchover in the UK. The analogue TV signal will be turned off from 17 October in Whitehaven area of western Cumbria. First to go will be BBC2 before being followed by the remaining analogue channels on November 14. The move means that the 25,000 residents of Whitehaven will have to switch to Digital TV by those dates in order to keep receiving TV.

In order to receive Digital TV people will need to purchase a Freeview set-top box or subscribe to satellite, cable or broadband TV in order to keep viewing TV. New equipment, installation and support will be given to people over 75, those with significant disabilities and the blind. The assistance will cost 40 pounds, or will be free for eligible people who are also on pension credit, job seeker’s allowance or income support.

Letters are being sent to everyone in the area explaining how the Digital TV switchover will work and what they need to do to keep viewing TV. On screen messages will also appear on analogue channels from May warning viewers that the analogue signal will be turned off in the next few months.

The Digital TV switchover will then be carried out region by region, with the rest of the Borders the next to have its analogue signal switched off, beginning at the end of 2008. By the end of 2012 the analogue signal will have been turned off across the whole of the country meaning everyone must have switched over to Digital TV in order to keep viewing TV.

Broadcasting minister Shaun Woodward said: “We’ve been fully engaged with preparing Whitehaven for a long time and it will - I underline that - be a success. Nobody in Whitehaven will be left behind because it is critical everybody understands it is happening.”

However, concerns have been raised as only 27% of households in the affected area, almost 7,000 homes, have yet to switch to digital. This is largely because Whitehaven cannot yet receive Freeview and so satellite has been the only option for residents.

There have also been concerns that many people, particularly pensioners, do not know enough about the Digital TV switchover and that more needs to be done for them. Age Concern’s director general Gordon Lishman said: “We will continue to champion the need for additional support for all older people who need it, not just the over 75s, and for a range of technology to be made available through the scheme. Measures must also be put in place so that vulnerable people are not exploited by rogue traders during the switchover.”

First of all, unlike earlier satellite communications which relied on a motorized dish to chase the mobile satellites across the sky, modern satellites are placed into a geosynchronous orbit about 37,000 km (22,300 miles) up. This means that they always remain above the same point on the earth’s surface. That way, all dishes on the earth can be pointed at a fixed location, and the satellite will always be there.

The signal to be broadcast originates at an “uplink center”, which collects nationwide programming from cable television networks and local programming from broadcast networks and encrypts it so that the programming cannot be intercepted by non-paying users. The uplink facility uses a huge dish, 9 to 12 meters (or 30 to 40 feet) wide, to accurately send a high-strength signal to the orbiting satellite.

The satellite, in turn, converts the signal to a different microwave frequency band, so that the downlink doesn’t cause interference with the uplink. The two most common frequencies used in United States satellite tv broadcasts are the “C-band” (4 to 6 GHz) and the “Ku band” (12 to 18 GHz).

After traveling more than 50,000 miles, and being converted in between, the signal that arrives at the receiving dish on the outside of the consumer’s home is fairly weak. It is focused by a bowl-shaped parabolic dish onto a device in the center called a “feed horn”, which channels the signal to a “low-noise block downconverter” (LNB) which filters out unwanted interference, and sometimes converts it to yet another frequency before amplifying it and sending it to the satellite receiver box inside the house through a coaxial cable.

The satellite receiver box converts the signal to an analog television, audio or data signal. The receiver may be equipped to decrypt the coded signal itself, or it may require a separate box or a “smart card” plug-in (either to the receiver box or to the television to perform the decoding. A single receiver can serve only one television or computer; multiple receivers must be purchased to provide signal to multiple devices, including watching one channel and recording on another.

Many receivers also include integrated digital video recorders (DVR), allowing them to rewind and pause live television, and to record and store their favorite shows on a built-in hard drive. There are also increasing numbers of high-definition television (HDTV) satellite receivers and DVRs available.

Newer technologies being integrated into the system include pay-per-view functionality, interactive television channels, and video-on-demand (VOD) channels.

The competition for between satellite tv providers, and between satellite and cable providers, is quite fierce. The advantages of being the first to provide new features are driving the pace of invention among satellite technology providers, so we can expect to see many more breakthroughs in the near future.

A computer is one heck of a tool for working on. It can launch ships. Run incredibly complicated calculations and it can even help organize almost endless amounts of data. But, where a computer at home really shines is in the fact it’s one heck of an entertainment device. Now, as the power of the computer is tapped into more readily, the PC TV is stepping forward to offer new entertainment solutions.

The PC TV offers some advantages over regular television that were previously only imagined. These advantages include such things as:

* On-demand capabilities. A Personal computer TV that’s hooked into a good service for finding and playing different shows can give users almost unlimited abilities to watch shows when they want and how they want. Rather than having to wait for a set time, a PC TV can locate a program on different stations and play it when users are ready to view. Depending on the services chosen, the video ability can be downloaded, streaming or both.

* Selection. Most personal computer television programs on the computer give their users a level of selection that covers more channels than most people even knew existed. Depending on the service that’s used to create a PC TV set up, stations can be piped directly onto a computer from anywhere in the world or shows can be chosen for download.

* Pricing. The actual fees involved in computer TV service are a lot less than most people would think. Depending on the program in question, a set up that’s reliable can cost as little as a one-time fee. Other services might charge by the month or year, but overall the selection versus the price of regular cable pretty much defies comparison.

* Reliability. As computer TV set ups become more widely accepted and embraced by television companies, Internet providers and computer users themselves, the reliability and quality is getting better and better.

As PC Television services moves forward in complexity, the set ups behind these systems are becoming better. More companies are starting to introduce services that enable a wireless link between regular computers and larger screen televisions. This means fans can download or stream their favorite shows on their computer, send them to wireless boxes and watch the actual shows on their television sets.

Technological advances in computer television seem to be growing in leaps and bounds every day. The biggest upcoming trend involves the ability to use a PC Television setup and pipe signals to any portable device that’s hooked into a homeowner’s network. This means a show can be sent from a PC to a portable device or any television in a home at the flick of a switch or darn near close to it.

Computer TV wasn’t much to look at a few years ago, but as online viewing gains in popularity and demand, the programming options for viewers are becoming incredible. Viewers who choose to go this route can watch what they want, when they want it almost without exception thanks to today’s technology.

Enjoy convenient, affordable PC TV

What is a satellite? A Satellite is an object that orbits another object. There are many kind of satellites used for many purposes. For communication and entertainment artificial communication satellites are used. The orbits that are in use for satellites are geosynchronous orbits, low Earth orbits, and Molniya orbits.

What is comsat?
It is an artificial communication satellite. When compared to the other two orbits the geosynchronous orbits are best suited as it can hold a ground-based antenna, which face the satellites. For television ground antenna are essential. Arthur Clarke first founded this method in 1929.

There are different satellite reception modes. To name a few there are Direct broadcast satellite and Television receive only satellite. Direct to home or direct broadcast satellite or mini dish system, is a recent development in the world of communication satellite. The direct broadcast satellite is a completely closed system and it uses proprietary reception equipment. Direct broadcast satellite uses the Ku band and sometimes it can run in C-band satellites. For the functioning of direct broadcast satellite system, encryption based on proprietary reception equipment and proprietary transport stream encoding is required. Direct broadcast satellite uses a smart card as part of the decryption system, which keeps a check on the authorization of subscribers.

Television receive-only, or TVRO, is open standard equipment and referred to as big dish satellite. Television receive-only is a well designed to receive for both television and radio as analog and digital satellite. Television receive-only uses both C-band and Ku-band transponders on the same level. Television receive-only or big dish satellite, as the name suggests uses larger satellite dish antennas. Additional receiver boxes are also used for receiving different types of digital satellite signal reception.

The digital revolution from space is altering the way that we receive information. The more advanced form of digital broadcast system is set-top box. Set-top box is a device, which receives signals, decode digital broadcast, and makes the television user interface friendly to the Internet. Its one of the main feature is to enable analog television to receive digital broadcasts.

Overall, there is a large improvement in the evolution of television relay system. That is from broadcasting through cable to broadcasting via satellites. There was again an evolution in the satellite system itself. For broad casting via satellite system, large dish were in use. Then came the mini dish to receive signal. The mini dish is sophisticated and easy to use system where tuning and maintenance was lot more easy than the traditional dish.

Televisions are the chewing gum for the eyes- Frank Lloyd Wright (1869 - 1959) and Satellites are the 1970’s lava lamps.

With the advancement of technologies, satellite television came in to existence. Satellite television is a revolution when compared to terrestrial and cable television, as it received signals from communication satellites in the space. In many places these satellite television supplement its conventional counterparts to get wide range of channels.
For years, satellite television is not an acceptable one as it had many disadvantages of fixing a very large satellite in a place and then lining it to the appropriate satellite. It even took months to set it by trail and error method. Bad weather is always a hindrance to this method of broad casting.

In the conventional method, the radio wave signals often disrupted and proper broadcasting was not possible as it was not inline with the antenna, which transmits these signals to the surrounding area. To get a perfect signal you should be very close to the broadcasting area.
Whereas satellite television, receives the signal from satellite dishes, which is in the geo-synchronous orbit of the space. It orbits in elliptical inclination or in geostationary orbit of 37,000 km above the earth.

Earlier in 1980’s the Consumer satellite television reception was highly were expensive and the dishes used were as large as 12-foot height. It had a motorized, multiple satellites reception. In 1995, easily usable small dish network came in to existence. Now, direct broadcast satellite (DBS) is usage to enable the satellite provider to select programs and broadcasts them to subscribers as a set of packages. It is a digital broadcast, which means transmission happens in Ku frequency range (12 GHz to 14 GHz).

Like other Satellite relayed communication, Satellite television uses an antenna, which is mainly located in uplink direction. These are mainly nine to twelve meters in diameter. These large structures are required for accurate and increased signals from satellites. These uplinked dishes placed in such a way that they receive to a particular frequency range from the satellite, which is in the space. Then these satellites in space, retransmits, or resend the signals back to these uplinked dishes in earth in a highly different frequency from the previous one. These kind of receiving the signals are termed as downlink. C-band and Ku -band are used for uplink service. The signal, received from the space, becomes weak. Therefore, these uplink dishes do conversions of the signals to low- noise block down converter. Then these radio waves get converted in to electrical signals from C-band and Ku -band to L-band. The L-band receives the signal through coaxial cable and converts in to desired output.

However, the process may look very complicated. These are the units, which are the eye of the satellite television, which helps in uninterrupted service of information and makes a pathway for everybody to enjoy the new access to the information age.
