The process involves sending and receiving information in digital data packets. This is the same method used by the Internet and other computer networks. The difference is that information pertaining to IPTV is transferred over separate, closed networks, independent of the one used for the Internet. This provides the benefit of a less congested, more efficient means of delivery, allowing for higher quality and more interactive features.
Vs. Satellite TV: One of the most common complaints about satellite television service is that there may be a loss of signal in poor weather conditions. When the weather is particularly bad, you can lose all reception, missing your favorite shows. In some areas this is a regular problem, while others may only rarely have these problems. Also, the weather does not even need to be particularly bad. Sometimes, only partially cloudy skies or windy conditions have been known to interfere with the satellite signal.
While satellite TV is not necessarily a poor service, IPTV does provide more reliable and higher quality service nearly every time. The weather plays virtually no direct role in the quality or consistency of IPTV service.
Another common problem with satellite television is that the satellite dish needs to have a clear view of the southwest sky. If there is a particularly high, or very close tree line or building blocking the view, service cannot be provided. This can also be a problem if you live in an apartment or condominium, which is facing the opposite direction, as there may not be a proper place to mount the satellite dish.
Vs. Traditional Cable: Early on, consumers reported that their IPTV service was not really much better than service provided from traditional cable. With the most recent developments, however, IPTV is definitely benefiting from a competitive edge, provided by new capabilities that integrate Internet content, features, and usability into the TV set. ,IPTV has many advantages over conventional cable, including high-speed internet access, video on demand, hundreds of channel choices, interactive features, on-screen caller ID, and many more benefits that traditional cable does not provide.
IPTV is growing in popularity due to these advantages over alternative television service. It is estimated that IPTV will provide service to well over 20 million households by the year 2008.
