Digital HD Receiver

The exciting new world of digital radio and television offers many benefits over the old analogue systems. It provides better picture and sound quality without the problems common to analogue reception, like interference during bad weather. Unfortunately, digital technology can be confusing because of the new and unfamiliar terminology, and it can also be expensive to upgrade to digital. However, time is running out to change to digital as analogue systems around the world are being phased out. Older televisions will soon no longer work so a digital HD receiver will be essential to get the best possible reception when the changeover happens.

Digital HD stands for digital high definition signal. Every television and radio needs its own digital HD receiver to be capable of using the new signal. While early attempts at high definition television (HDTV) used an analogue signal, HDTV is transmitted in digital these days. Most new televisions already have a receiver built into them, and set-top boxes are available for those that do not. Digital HD should not be confused with standard definition, which is also a digital signal but has less resolution. Standard definition receivers are not capable of decoding high definition signals.

Radio stations now broadcast digital signals along with their analogue signals. The digital signals provide superior quality sound with less interference. They also include information that can be displayed on front panel of the radio, such as the title and artist of a song. Information about traffic and weather conditions is also broadcast continuously by most stations. To use these new digital signals, a radio needs to have a digital HD receiver. In the past, digital radio was restricted to large sets because of its high power usage, but portable models are now starting to appear.

Many flat screen televisions have a digital HD receiver already built into them. This avoids the extra cost of purchasing a set-top box and the problem of finding somewhere to put it, as well as having to use two remote controls to operate the television. While standard definition provides an acceptable picture on small screens, larger screens benefit more from using high definition. High definition has twice the resolution of standard definition, providing a picture which is sharper and more detailed. It also provides true widescreen viewing without the need for letter-boxing or stretching.

Televisions without a digital HD receiver can be converted to digital by installing a set-top box. These boxes are connected between the antenna and the colored AV inputs on the television, and they also need to be connected to a power outlet. For older televisions that only have an RF input, a modulator is also required to convert the signal from the set-top box. However, modern flat screen televisions are now so affordable that it is usually impractical to convert these older televisions. For a slightly higher cost, a flat screen with a digital HD receiver will provide a much better viewing experience.

To get the most out of a digital HD receiver, it needs to have a strong input signal from the antenna. Older antennas were designed for analogue frequencies, but digital signals are broadcast over different frequencies. While most antennas are capable of picking up digital signals, they may not get the best possible reception. Digital antennas are tuned to get the strongest signal at those frequencies. Digital signals do not suffer from static or interference like analogue signals. Instead, there is a total loss of reception when the signal strength falls too low. To get good reception in areas far away from the transmitter, a digital antenna is essential.
