Terrestrial is earthbound. It is broadcast from antenna towers here on Earth. Satellite TV is broadcast by communications satellites from outer space in geosynchronous orbit. They orbit at the same rate that the Earth rotates, therefore they remain "parked" over the same geographic region, relative to the surface of the Earth they are standing still. Terrestrial TV also makes use of satellites, but rather than broadcasting directly to a customers dish, they are broadcasting specifically for re-broadcast by local network affiliates over their terrestrial antennas.

What is the difference between terrestrial and digital television transmission?
Digital television is the opposite to analogue television. There are 3 ways of receiving digital television: 1) Satellite 2) Cable 3) Aerial (terrestrial) Thus using a terrestrial aerial is one method of receiving digital television (branded as Freeview in UK)
What is the difference between satellite tv service and cable Don't they all receive there signals from a satellite?
The difference between satellite tv service and cable is satellite tv offers more channels and are more expenisve. No, they don't receive their signals from a satellite.
What 's the difference between satellite and terrestrial?
IN COMMUNICATIONS: Satellite uses satellite (orbiting) relay-stations in Space but Terrestrial uses cable or antenna-to-antenna signals based entirely on Earth to broadcast your television, radio or cell-phone :) ++++ IN ASTRONOMY: Terrestrial means Earth- (or planet-) bound; a Satellite is any natural or man-made object that orbits a planet. The Moon is a satellite of the Earth.
Does Thornaby TS17 have terrestrial TV?
Yes - ALL areas of the UK have terrestrial TV - the majority of areas also have either cable, satellite or both. TS17 is not far from where I live.
Are all TV channels in Bangladesh digital?
Only Satellite Channels. Terrestrial Channels are only analogue.
Is there a difference in pricing between satellite and cable Tv?
The 2 industries are very competitive,they are constant proce wars going on.
what is the difference between DirecTV and cable TV?
DIRECTV is a satellite company and cable TV is not. DIRECTV has more channels and clear reception. Also, DIRECTV is a good company and satellite is much better than cable TV.
Why microwaves can be used for satellite TV communications but not terrestrail TV?
Microwaves can be used for satellite TV communications because they can travel long distances with minimal attenuation and penetrate the Earth's atmosphere effectively, allowing signals to be transmitted from satellites in orbit to ground receivers. In contrast, terrestrial TV often uses lower frequency signals that are better suited for covering shorter distances and penetrating buildings. Additionally, terrestrial TV relies on a network of ground-based transmitters that are optimized for local broadcast rather than long-range transmission like satellites. Thus, the characteristics of microwaves make them ideal for satellite communication, while terrestrial systems utilize different frequencies.
Do you have to pay for a cable box each month if you get an HDTV with a digital tuner?
There are several alternatives to cable for HD television. They are dependant on the television and also the location. Terrestrial broadcasts are now being offered in HD. A television with an HD tuner needs no other equipment to receive HD terrestrial broadcasts but a digital HD terrestrial receiver box may be needed. Most areas have satellite coverage. Sky in the UK and Dish Network in the US are two examples. The UK also has the Freesat service - a free satellite service that includes SD and HD broadcasts. A suitable satellite receiver is needed but there is no subscription to be paid. Cable providers provide competitive services to terrestrial and satellite broadcasts but almost all demand a monthly subscription. Depending on the location, satellite and terrestrial broadcasts offer free to air services as well as subscription channels. Local television retailers will be able to advise on the availability of broadcasts in your area but be aware that their intention is to sell equipment and sesrvices to you so their advice may be biased towards subscription based solutions.
What is the difference between microwaves in ovens and microwaves used in phones and satellite tv?
nothing really, they are just put in different devices to make them perform different jobs.
What type of electromagnetic waves are used in satellite TV?
Satellite TV uses microwaves, which are a type of electromagnetic wave. These microwaves travel between the satellite in space and a receiver on the ground to transmit television signals.
What are the basic differences between cable and satellite TV technology?
satellite cables and TV cables are the same to a point. the difference in the too are is the TV cable a RG59 or a RG6 RG59 will not work with satellite because if the smaller center conductor with satellite it pushes power were it will end up destroying the center conductor RG6 witch is in newer homes is ideal for both satellite and cable RG11 is used with TV cable from usual the box / tap outside to houses usually running over 300 ft depending on the DB coming from the starting location
