Television，or TV， the modern wonder of electronics，brings the world into your own home in sight and sound. The name television comes from the Greek word tele， meaning "far"， and the Latin word videre， meaning" to see". Color TV is based on the principle of color addition. Any color can be obtained by the addition of the three primary colors， red， green and blue. When the three primary colors added together， other colors can be produced by varying the intensities of the primary colors. Let us be clear， we are not talking about painting or printing， we are talking about colored lights failing on a screen， which are additive color mixing. A color TV picture is actually a monochrome picture but with colors added for the main parts of the scene. It approximates to the process of painting color on a black and white photograph. The required color information is in the chrominance signal. To illustrate this idea of the color being in a separate signal，you can turn down the color control to eliminate the color signal， and the resuh is a black-and-white picture. The monochrome picture is produced by the luminance signal. With both the color signal and the luminance signal， the picture is reproduced in natural color. There are many schemes that have been proposed for transmission of color TV， e. g. NTSC， PAL， and SECAM. These differ in detail， but all utilize the same basic philosophy. TV is the most commonly used image communication system in the world today. However，present TV transmission Standards are based on the technology that is more than 40 years old. As a result，there has been widespread interest in the consumer electronics industry to develop more advanced TV systems that benefit from recent technological advances. Studies in the U. S. proved the feasibility of the alldigital TV， which was believed to be unrealistic not too long ago. Digital TV refers to digital representat！on and processing of the signal as well as its digital transmission.
