We can get television channels in some way: the traditional analog RF wireless, cable TV, analog and digital (DVB) wireless satellite TV, or even internet TV (webTV).

The most popular is cable TV. It delivers high quality of pictures with relatively affordable equipments. But, the coverage of the service is not available at all places. Just some area are covered, in general available at big cities.

Internet TVs is another solutions for the coverage problems. You can use this service everywhere, as long as internet connection is available. The coverage is better, and unlimited theoretically. But, the problem is about the internet connection itself. In some countries, quality internet connection is rare. You will need a broadband internet connection for television purpose. Even more for HD shows. The internet connection cost is separated.

Direct satellite TV need more complex equipments, and complex configuration. You will get the television channels direct from the satellite broadcast. You must have a satellite antenna (most is parabolic antennas) that configured to receiving a television signal from satellite, a satellite for a time for each antenna. The position is very important, the position of antenna is affecting the quality of the pictures. Then, you must have the receiver to process the satellite signal, and optional "decoder-capability" to decode the digital television signal, before shown on your television.

But, the advantage is its coverage. Satellite based service, such as Direct TV, has relatively large coverage. So, you can enjoy international television channels, even you are in the middle of the small village that has no cable TV service or even the traditional UHF television. Direct satellite televisions service (DirectTV) is recommended for you, if you need quality television channels but there is no local service coverage on your place.

You can enjoy the FTA (Free to the Air) programs for real free! FTA programs is free, then satellite connection is free. You just need the equipments, and mission accomplished. But, there are also available paid programs. You need to pay the programs, but the connections is still free. A local government's policy about satellite frequency use and license are another "local specific problems".

Even with Directv, you are offered with DVR option. With DVR, you can record the television shows, and then you can watch it later, whenever you want.
