It's the wave of the broadcasting future: Digital television (DTV) brings viewers the clearest picture and sharpest audio possible, with improved resolution and more capabilities than standard analog television. If you're still watching analog television, it's time for change. Take one look at digital television, and you'll never go back to standard TV. For TV fans who still need convincing that digital television is the best TV out there, here are a few reasons to give DTV a try:
The difference between regular TV and digital TV is like night and day thanks to the large number of pixels utilized in digital television. The higher the number of pixels, the more improved the picture. Digital TV's reliance upon binary code - the very code that brings clarity and smoothness to computer monitors and CDs - also makes for a superior picture and sound. Also, digital television features a higher aspect ratio than analog TV. In fact, the aspect ratio of digital TV is twice that of analog TV, resulting in a wider screen and crisper picture.
Digital television is opening up a whole new world for broadcasters. With digital TV, broadcasters can now transmit programs on various kinds of signals, including high def signals. High definition television (HDTV) signals are amazingly superior to analog signals, with five times the resolution. HDTV signals deliver a wide screen picture with superior detail and clarity, as well as the best audio experience availabale.
For viewers who are serious about home theater, digital television is an absolute must. Recreating that amazing movie theater experience at home is easy with DTV. Digital TV accommodates Dolby Digital surround sound, as well as HD programming. Why watch anything else on that cool new wide-screen set?
Viewers who are considering investing in a new set and making the switch to digital TV should look at the following options:
The integrated high definition digital set: Giving viewers the ability to pick up both analog and digital broadcasts, this set can also receive HD signals. High definition integrated sets are available in two different models. One kind comes with an HDTV receiver. The other kind has HDTV capabilities, but doesn't have a built-in HDTV receiver. The receiver must be purchased separately and attached to the TV.
The digital tuner/decoder box and a digital TV monitor: You can get DTV with a digital tuner/decoder box. With the addition of digital monitor, you'll be able to get the best in both audio and video. These components are sold separately.
Keep in mind, too, that digital cable or digital satellite television and digital television are completely different things. Digital cable and digital satellite television involve the conversion of a digital signal to an analog signal, whereas DTV is digital all the way. Digital TV sets can now be purchased for less than $2000 and are becoming more and more popular. It's easy to see why!

There are three basic steps involved in the transmission of a television programme. These are:
· Material – this is the programme itself
· Master control – this selects the programme to be transmitted
· Effects – this includes the network identifier
The programme itself can be in a number of different formats. A live transmission is where the material is coming directly from a live feed, such as a sports or news event. A second source of material is from a digital video server. This is basically a huge computer hard drive that has various pieces of material recorded on it that can be played at any time. The final type of material is from tape. This tape tends to be digital video, but analogue tapes can still be played too using a special analogue-to-digital converter.
The master control operator, or transmission operator, is responsible for selecting the correct programme to air at the right time. This can be done manually, usually in a live programme, or automated using a transmission program. During a live event, the operator is responsible for selecting commercials at the ad breaks, and then going back to the live feed at the end of each commercial break.
If the material is pre-recorded, either on tape or server, the operator is responsible for starting the material playing, as well as ensuring that the feed is being transmitted. Most television networks use an automated system, and the operator simply loads in the day's schedule. The rest of their time is spent monitoring the transmission, and ensuring that the material for the day is loaded into the VCRs or digital video servers as appropriate.
The effects that we see on many television programmes have become so common that we often don't notice them. But everything that is superimposed on the actual programme has to be controlled by a transmission operator, or automated transmission system. These include station identifiers, scoreboards, and ‘tickers' with information scrolling across the screen.
