What are the advantages of cable TV?
When the media of the television was first introduced, viewers had no choice but to use roof antennas or so -called "rabbit ear" antennas to get broadcast signals. If the location of the transmitter and the location of the television file was not optimal, the signal could be weak to practically do not exist. In order to face this signal loss, some local television services would be the length of the coaxial cable for some customers to pay a subscription fee to cover the company's expenditure. This became the first generation of cable TV services, although it was not designed to provide more than to provide customers with the same network broadcasts as those who have a clear income through antennas. One of the first advantages solved by the earliest cable TV systems was a better reception. The tel was no longer needed by Evisios to make numerous interior rabbit antenna or outer antennas mounted on the roof. The cable television signal bringsThe work directly into the inner tuner of the television file, resulting in a clearer picture and improved sound.
Cable TV technology also allows many channels to share broadcasting space on the same delivery system. Instead of maintaining separate transmitters for each free air channel, the same transmission system can carry hundreds of channels by assigning each of them a specific frequency along the spectrum. These channels provide viewers different types of programming focused on specific interests. Traditional broadcast channels often represent sampling of different types of programming, but they cannot devote all their broadcast time to one viewer.
Some people prefer cable television because the provides unique programming without some restrictions on the content placed on traditional networks. Because cable TV is a closed system, they have access to channels that decide to watch, just subscribelets. The cable channel has the right to show programs that contain a strong language, suggestive sexual content or violent images if this information is clearly communicated to the viewer before broadcasting. FCC regulations on cable TV content are not as strict as regulations stored on traditional free air networks.
Many cable television systems also have the ability to provide subscribers telephone service and Internet access through a high -speed digital modem. All these services can be connected together at a reasonable monthly rate, eliminating the need for separate phone accounts and accessing the Internet with other providers. Some cable television systems have interactive functions that allow viewers to select specific programs and maneu there to monitor or provide digital recording for later control.
since June 12, 2009, virtually all television stations working in the United States must broadcast their SIGnals in digital form, not an older analog format. Because cable TV signals are already digital, subscribers do not have to buy special boxes for analog digital converters to constantly receive regular programming.
