events and news from around the world. The Satellite TV Solution

Satellite television solves the problems of range and distortion by transmitting broadcast signals from satellites orbiting the Earth. Since satellites are high in the sky, there are a lot more customers in the line of site. Satellite television systems transmit and receive radio signals using specialized antennas called satellite dishes.

The television satellites are all in geosynchronous orbit, meaning that they stay in one place in the sky relative to the Earth. Each satellite is launched into space at about 7,000 mph, reaching approximately 22,200 miles above the Earth. At this speed and altitude, the satellite will revolve around the planet once every 24 hours -- the same period of time it takes the Earth to make one full rotation. In other words, the satellite keeps pace with our moving planet exactly. This way, you only have to direct the dish at the satellite once, and from then on it picks up the signal without adjustment, at least when everything works right.

At the core, this is all there is to satellite television. But as we'll see in the next section, there are several important steps between the original programming source and your television.

Future of Satellite TV

Satellite television is television delivered by way of orbiting communications satellites located 37,000 km above the earth's surface. The first satellite television signal was relayed from Europe to the Telstar satellite over North America in 1962. The first domestic North American satellite to carry television was Canada's Anik 1, which was launched in 1973.

Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. Uplink satellite dishes are directed toward the satellite that its signals will be transmitted to, and are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. The increased diameter results in more accurate positioning and improved signal reception at the satellite. The signal is transmitted to devices located on-board the satellite called transponders, which retransmit the satellite signal back towards the Earth at a different frequency.

The satellite signal, quite weak after traveling through space, is collected by a parabolic receiving dish, which reflects the weak signal to the dish's focal point and is received, down-converted to a lower frequency band and amplified by a device called a low-noise block down converter, or LNB (Direct broadcast satellite dishes use an LNBF, which integrates the feed horn with the LNB).

A new form of satellite antenna, which does not use a directed parabolic dish and can be used on a mobile platform such as a vehicle, was recently announced by the University of Waterloo. The signal, now amplified, travels to a satellite receiver box through coaxial cable (RG-6 or RG-10; cannot be standard RG-59) and is converted by a local oscillator to the L-band range of frequencies (approximately). Special on-board electronics in the receiver box help tune the signal and then convert it to a frequency that a standard television can use.

Types of Satellite Television

There are two primary types of satellite television distribution:

1. Direct broadcast satellite (DBS)

2. Television receive-only (TVRO).

TVRO – Television Receive Only

TVRO was the first satellite system available for home viewing of satellite TV. It required a relatively big dish of 3 to 6 feet in diameter and worked in C-Band. Frequencies of around 4 G Hertz are called C-Band and require bigger dishes because the wave length of these frequencies is longer than in Ku-Band which requires a much smaller dish of about 18 inches. Ku-Band is at 12 to 14 G Hertz.

TVRO systems also need a movable dish because it needs to get all the channels of many satellites. C-Band satellites have much less channels available than Ku-Band satellites and therefore more satellites are needed to provide enough channels. Possibilities that exist with TVRO systems are that you can also receive free channels and independent feeds from for instance news www.mcsweb.in companies. You could for instance receive the unedited material that is broadcasted from a news crew somewhere in the coverage area of the satellite. They transmit their materials to their headquarters using a C-Band satellite. Many of these types of feeds are not scrambled and are available to everyone with the proper equipment.

TVRO systems are often referred to as Big Dish TV, C-Band Satellite TV and BUD (Big Ugly Dish).

DBS - Direct Broadcast Satellite

Satellite TV via DBS is done in the Ku-Band. These satellites work on higher frequencies and can transmit higher power signals. This means that much smaller dishes can be used to receive the signal. A small dish of 18 inches is already enough to receive all satellite TV by Satellite TV. This makes it possible to have satellite TV from an apartment on the 10th floor, if you have a clear line of sight to the south.

DBS is for everyone. The satellite dish is so small that it is not an obstacle like with for instance the TVRO dishes of 3 to 6 feet. Once installed the dish needs no maintenance since it is aimed at just one satellite. Some dishes actually have 2 or more feeds which makes it possible to receive the signals from more than 1 satellite.

There are no free channels available on DBS satellites as these are often owned and used by the satellite TV provider it self, while TVRO satellites often are used by those who rent space on the satellite for a limited time. TVRO systems are meant for, for instance, transport of unedited materials between continents, but also within one continent.

DBS is meant for everyone with a simple, low cost installation of the system. Often the installation is for free as it really is very easy to do. www.acting-international.com The only thing that is needed is a bit of knowledge of where to find the satellite and the tools that make this even easier. A qualified installer will find the satellite and point it to maximum reception within minutes.

When satellite television first hit the market, home dishes were expensive metal units that took up a huge chunk of yard space. In these early years, only the most die-hard TV fans would go through all the hassle and expense of putting in their own dish. Satellite TV was a lot more difficult than broadcast and cable TV.

Today, you see compact satellite dishes perched on rooftops all over the United States. Drive through rural areas beyond the reach of the cable companies and you'll find dishes on just about every house. The major satellite television companies are bringing in more customers every day with the lure of movies, sporting events and news from around the world. The Satellite TV Solution

This article may be considered science fiction, just like Arthur C. Clark once had a scientific vision about 3 satellites orbiting the earth in geostationary orbits to make global communications possible. Everything in this article is merely a scientific vision and an extrapolation of current technologies into the future.

What would be the future of Satellite TV? That may seem to be a difficult question, but extrapolating what we know about the past into the future and some educated guesses, we may very well end up with a reasonable picture of what the future of satellite TV looks like. The future of satellite TV will be guided by these properties:

Receive and Transmit
Equipment Size and Costs
Satellite Capacity and Coverage
Antenna Size
New Technologies
