For television fans who can’t make up their minds about which station to watch, a Taiwanese manufacturer has come up with a solution. The firm has introduced a three-screen television set. The unit features a 19-inch (47.5 cm), colour screen flanked on one side by a pair of 5-inch (12.5 cm), black-and-white screens mounted one above the other. Three channels can be watched at once, and using a remote control a viewer can rotate simultaneous broadcasts from one screen to another simply by pressing a button. One or both of the similar screens can also be hooked up to a closed-circuit camera, thus functioning as a security-surveillance monitor.

How does digital television work? Basically it performs by splitting the continuous analogue signal into a series of separate pulses. A continuously varying electric signal generated by a usual broadcasting camera is fed into an electronic device which converts it into pulses. These pulses represent binary recordings of the signal’s values at any given moment. At the receiving end of the circuit, the digital signal of binary pulses can be unscrambled back into the analogue signal which is then fed into ordinary TV sets. But the advantages of digital techniques can themselves be used in TV sets in order to improve their reception qualities considerably.

Digital TV has its disadvantages. The main one lies in the tremendous scope of information to be transmitted. And it must be done at the rate of 216 million pulses per second. This great flow of information is rather difficult and extremely expensive to transmit over great distances by the technical means available today.
Russian researchers studying this problem have found help in the principles they observed in living nature. And the efforts of Russian researchers in this field are internationally recognized.
