March 23, 2010 - PRLog -- Digital TV is perfect and offers better quality images and audios on your Television screens.  Transmission of analogue television started in 1950. Now Digital TV has arrived to replace analogue TV. Some people may ask when analog system still works then what is the use of switching to DTV? Advancements has been achieved in every sector. For instance in music industry, earlier there were round shaped records, then cassettes came and now CDs and DVDs are available which can store enormous amount of data and can be played anywhere on CD and DVD players.
In digital TV, the TV signals are broad casted on low bandwidth. Signals transmitting on low bandwidth provide you better picture quality. Digital TV is popular for offering high end picture and sound quality. Analog television sets use magnetic waves to transmit the audio and video signals whereas digital sets use digital signals to provide superior audio and video quality. Quality of picture is determined by the resolution in pixels. More number of pixels means better image quality. Regular analog system has a resolution of 512 x 400 pixels. Simple computer has resolution of 640 x 480. The high quality monitors or DTVs provides ten times better picture quality than analog. Digital television runs many different picture formats which are defined by the combination of size, width to height ratio and interlacing. Various picture formats that can be transmitted over Digital Television are:
High Definition Television (HDTV)
Standard Definition TV (SDTV)

The quality of these new digital transmissions will set the standards for the future of broadcasting. SDTV is a lower resolution picture than HDTV. The difference between SDTV and HDTV is that signal on SDTV is more compressed than that of HDTV. Because the digital signal is compressed, broadcasters can transmit five SDTV programs, whereas HDTV can only broadcast a single program. Multiple program broadcasting is known as multicasting. It was not earlier available with analog transmissions. The picture definition of SDTV is also slightly lower than that of HDTV.
