Satellite Delivery for entertainment TV radio and in certain cases, Internet, provides a perfect solution to the wandering traveller as well as those who are in poor terrestrial reception areas.
The Campersat Division of Videosat is specifically dedicated to travellers and the need to provide superb reception of Satellite Delivered Programs.
Satellite delivery has now become the delivery method of choice to get services across this wide nation of ours. Providers now include:
• ABC and SBS services of TV and Radio free of charge
• Commercial service free of charge via satellite Commercial Broadcasters
• Traditional Pay TV providers such as Foxtel and Austar
• New Pay providers such as SelecTV
• Narrowcast channels providing services to special interest groups. Including ethnic and religious providers
• Internet Services
Satellite television and radio is available anywhere in Australia in superb digital quality.
Better still, satellite reception is not affected by the usual sources of interference that typically interrupts terrestrial (local antenna) reception. These can be caused by weather patterns, topography such as mountains or buildings, local electrical interference, even the earth's curvature can interfere with great picture and sound.
Satellites have none of these restrictions. Best of all, because you own your own satellite system, there are no monthly fees. With Campersat, you can enjoy your favourite free-to-air television programs for ABC, SBS, Channels 7, 9 & 10 (via satellite delivered regional services) with a wide range of radio services available wherever you go.
With the advent of digital terrestrial services most of us are now familiar with the quality of digital broadcasting, particularly with the advent of new lightweight flat screen TV's. Virtually all satellite transmissions have been digital since 1999.
Don't forget that despite fact that terrestrial services are now digital all over Australia, do not expect extended coverage. Terrestrial digital services have the same line of sight transmission restrictions as before. Further Understanding
A brief understanding the functions of satellite receiving systems What to look for when choosing a Satellite System
Virtually
all of the communication satellites we are dealing with are positioned
36,000 km above the equator travelling the same speed as the earth.
They appear stationery in the sky when "seen" from the ground and are
often called geo-stationary satellites.
Because
they seem fixed when viewed from earth, satellites make excellent
broadcast and telecommunication relay stations. Thus a transmitter on
earth beams a signal to the satellite which is received, enhanced and
retransmitted back to earth. This trip up and back, a distance of over
70,000 km, lasts for about 3/10ths of a second.
The
satellite is powered by the sun through solar panels. Because the
available power is minimal, the retransmitted signal is quite low.
Transponders on the current series Optus Satellites are nominally 50
Watts (Compare this to an ordinary 60 watt light bulb!).
Satellites
are owned and operated by carriers �eg (Optus-now part of Singapore
Telecom who operates four satellites (A2, A3, B1,B3 and recently
D1).and others such as Pan Am Sat (Pas8)
We
are interested in satellites providing services to Australia, Papua New
Guinea and New Zealand providing a range of broadcast and distribution
services (video, audio and data).
Virtually all services are digital with many many services being carried by one satellite.
These
days satellite operators shape their signal pattern to meet market
requirements. Translated this usually means satellite power is not
wasted in sending services where they are not needed.
Most services are now encrypted to service controlled markets and this includes assess to many free serivces.- Yes ABC/SBS and Commercial regional Satellite TV is encrypted.
It is very important to understand this so that you purchase correct
equipment, properly configured for the services you wish to view. There is no free lunch in this game.
Likewise Subscription services are managed to ensue that only viewers who are entitled to view services are able to do.
