High-Definition Television, better known as HDTV, is a form of broadcasting system that has a higher resolution than traditional broadcasting systems. The use of HDTV became widespread because it uses less bandwidth and video compression.
Rise of High Definition TV
Although the MPEG-1 video standard was used in digital TV, it paved the way for more advanced TV standards. Over the years, there was a growth in large screens and projectors in the market and using these devices revealed the limitations of the SDTV technology.
However, an HDTV still requires a High Definition signal to produce superior picture.
To obtain signal, you can try the following:.
- You can use an antenna, but this still requires an HD tuner. However, most HDTVs nowadays are already equipped with an HD tuner. If not, then you can purchase a High Definition tuner box from your cable or satellite company.
- Most computer devices today come with either a DVI or HDMI interface that is required to produce images for an HDTV.
- Most digital or cable companies offer their clients an HDTV set-top box so they can get the HDTV channels for free.
Advantages of HDTV
When it comes to quality, a High Definition television usually produces more quality pictures and images than the standard ones. This is due to the higher number of resolution lines; hence, there is a narrower scan line that is almost invisible to the eye. This results in a sharper image when the visual information is translated into your television sets.
You can also expect fuller sound capabilities because the HDTV video signal comes with Dolby Digital 5.1 surround sound.
Disadvantages of HDTV
Although the concepts of HDTV technology sound quite pleasing, it is not often achieved in practice. The reason behind this is High Definition TV specifications are often not followed to a full extent. Some operators reduce the resolution to include more channels, thus sacrificing the quality of the video.
Since the technology in itself is very sensitive, you need to practice the appropriate use of cables. Unless you properly input the device or configure them in the way they were designed, you cannot expect optimum results.
