I. Reading Exercises:

Exercise 1. Read and memorize using a dictionary:

monochromatic television; a field sequential color television broadcasting system; a compatible color standard; the lucrative black and white market; the uppermost line; a viable alternative compatible system; to reconstitute; to be compatible with; color reception; channel allocation; dot sequential system;

Exercise 2. Answer the questions:

1.When was color television demonstrated?

2.How does color television work?

3.What year did the first color television come out ?

4.Why was the color television invented?

Exercise 3. Match the left part with the right :

over a decade after the standard was set, that color TV sales rose significantly.

2. On 21 July 1953 the second NTSC approved

when the Columbia Broadcasting System (CBS) publicly demonstrated a field sequential color television broadcasting system.

3. It was not until the late 1960s,

in setting monochrome standards in the United States, was reactivated to investigate the status of compatible color systems.

4. The NTSC, the entity which played a key role

a compatible all electronic color television dot sequential system .

Exercise 4. Open brackets choosing the right words:

Experimental color broadcasting was( to introduce /to initiate) in 1940, when the Columbia Broadcasting System (CBS) publicly (to demonstrate/to show) a field sequential color television broadcasting system. This system (to use/to employ) successive fields scanned one at a time in one of the three primary colors; red, blue, or green. On the receiver end, a mechanical color wheel was used (to reproduce/to reconstitute ) the primary colors in sequence to enable (reproduction/ reconstitution) of the colors in the original scene.
