What is Digital Television and High Definition Television (HDTV)?

Digital TV broadcasting system has many advantages, including:

Sharp, high resolution images. Digital Televisions receive an identical copy of the TV picture that was transmitted, so they can show clear, sharp TV pictures.

Wider picture. With the Digital TV system, TV pictures can be one-third wider than traditional TV pictures. Digital TVs have wider screens to show all of the wider digital TV pictures.

Clear, crisp audio. Digital TV includes digital-quality stereo sound (with left and right channels), and for some programs, it includes 5.1 CHANNEL SURROUND SOUND.

High Definition TV (HDTV). Digital TV includes the ability to transmit programs in High Definition (HDTV), a high quality TV format with pictures that have up to five times more detail than traditional analog TV. (Viewers must have an HDTV and an HDTV signal source to see true HDTV pictures.)

Several TV programs can be broadcast in one TV signal (from one TV transmitter). This is called "multicasting." Inside the same space as one traditional ANALOG TV signal, DIGITAL TV can transmit several programs at the same time, including channels for future services like TV for cellphones and cars.

DIGITAL TV signals from community TV stations are local, portable, and free.

More on HDTV

High Definition Television (HDTV) is a newer standard in television technology which provides wide-screen picture quality similar to a 35mm film along with compact disc digital audio sound quality. The concept is not new; it has been there since 1998 but has been slow to pick up due to incompatible TV sets. Now with the availability HDTV sets which support the digital broadcast, stations are switching over to the HDTV format.

There are two types of television broadcasting signals, the older analog signal and the newer digital signal. The traditional TV viewing involved broadcasting an analog signal which the TV converted into sound and picture.

Analog television broadcasts have several drawbacks:

(I) Interlacing of analog pictures which make the picture flicker.

(ii) Converting a video signal to analog signal decreases the picture quality

DTV has several advantages:

A digital signal transmits the information for video and sound as ones and zeros instead of as a wave.

The picture is of far better quality on a small screen as well as a big TV

The video is progressive and not interlaced

TV stations can multicast i.e. they can broadcast several signals using the same bandwidth.

TV channels can offer multiple languages for the same show

The broadcast in 6 sound channels allows digital quality 5.1 surround sound.

The opportunities for the consumers are endless; being interactive the television set becomes much more than a picture tube.

HDTV Basics - LCD vs Plasma Screen Televsions

Plasma television technology uses three phosphors, namely, red, blue, green. When electricity strikes them, they give off light. The light that is being emitted will depend on how strong the electric current is. The phosphors are the one responsible for creating the light that you can see on the screen.

LCD televisions are composed of millions of crystals that are in a liquid medium and it is sandwiched in between transparent plates. Behind this, a bright light is placed. The crystals then either allow light to pass through or to be filtered. The filtered lights determine the colors that are displayed.
