Television—that most attractive modern technology, marked by rapid change and growth—is moving into a new era which promises to reshape our byes and our world. It is an electronic revolution of sorts, made possible by the marriage of television and computer technologies.
The word "television" can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a complete system of electronics, television provides the capability of converting an image into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver(television set), can then be electronically reconstructed into that same image.
Television is more than just an electronics system, however. It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool for reaching other human beings.
The field of television can be divided into two types. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques.
Traditionally, television has been a medium of the masses. It has been with us for about thirty-seven years in a form similar to what exists today. During those years, it has been controlled mostly by the broadcast networks, ABC, NBC and CBS, who have been the major suppliers of news, information, and entertainment. These giants of broadcasting have actually not only shaped television as a source of entertainment, but placed our role in this active medium as the passive viewer.
What kind of television is intended for small numbers of people?
选项
A、Broad-based TV.
B、Reconstructed TV.
C、Traditional TV.
D、Non-broadcast TV.
