High Definition TV Offers Realistic Broadcast Viewing
Many consumers have their eye on the picture quality of high definition TV and the digital programming, demanded by government regulations to begin in 2009 is already be broadcast on many networks. Essentially, high definition TV is the result of the signal being broadcast in digital format instead of analog and it is less affected by spurious transmission and weather interference.
Some of the older analog television sets, equipped with the antenna to pull the signals out of the areas, were often subject to snow on the screen due to a weak signal. They could also show interference when other electrical appliances were in use near the television. Cable and satellite providers did away with most of the interference, but digital broadcasts using a high definition TV and antenna can do away with the interference without subscribing to cable and satellite services.
Similar to frequency modulation broadcasts of audio, high definition TV broadcasts are in a digital format. Although they do require line of site between its origin and destination, causing some interference in satellite signals during periods of heavy clouds or storm activities. By the input signal is only a part of the plan for high definition TV program reception.
Receiver Must Be High Def Capable
Many homes are already receiving high definition TV broadcasts by cable or satellite providers while they still have an analog television. Although not all broadcasters have gone to a full digital format, the ones that do require a converter in or on the television in order to show the digital broadcast on older models of televisions.
Some retailers have already discontinued the sale of televisions equipped with analong tuners, preferring to only offer the high definition TV sets as they will become almost a necessity in the next few years. Those that have purchased a high definition TV and do not subscribe to cable or satellite, may not be benefiting from owning the technology. Although, high definition TV antennas are available to enable reception of high def signal being sent our by local broadcasters.
By the year 2009 when all programming is mandated to be in digital format, consumers will have to choose between owning a set-top box that coverts the digital signal to analog or to buy a new high definition TV. Most cable companies have already announced plans to offer the boxes for rent to help ease the price burden to its subscribers who may not be in a position to buy a new high definition TV.
