In a video camera, the sensor that picks up light is called a CCD. CCD stands for

• color-coding data
• custom color descriptor
• chroma-calculation daemon
• charge-coupled device
• carbon crystal digitizer

A computer’s output on a CRT is calibrated to display an image:

• smaller than the actual monitor’s capability
• larger than the actual monitor’s capability
• exactly the same size as the actual monitor’s capability
• that adjusts automatically to the monitor’s capability
• of a fixed size; whether it is larger or smaller than the monitor’s capability depends on the monitor

Removing a residual magnetic field that distorts the colors on a television screen is called:

• tracking
• dubbing
• streaming
• flattening
• degaussing

A video signal transmitted with all the signals mixed together and carried on a single cable is called

• RGB video
• composite video
• component video
• multiformat video
• chroma-key video

Which of the following is not a television signal format

• MPEG
• NTSC
• PAL
• SECAM

Computer displays draw the lines of an entire frame in a single pass; this technique is called

• streaming
• progressive-scan
• packing
• flattening
• overscan

The video technique that allows you to choose a color or range of colors that become transparent, allowing the video image to be visible behind those colors in the overlying image, is known by all of the following except

• blue screen
• Ultimatte
• chroma key
• interlacing
• green screen

Which of the following is a multimedia container format?

• JPEG
• DVD-RW
• ComponentY
• Hi-8
• Ogg

Red or green should be avoided as cue colors because

• they represent negative ideas in some cultures
• they do not blend well with other colors
• color-blind individuals cannot see them correctly
• they are associated with “stop” and “go”
• they remind people of Christmas

Which of the following is not a good idea when creating titles (text) to be used in video?

• Fonts for titles should be plain, sans serif, and bold enough to be easily read
• When you are laying text onto a dark background, use white or a light color for the text
• Do not kern your letters too tightly.
• If you use underlining or drawn graphics, make sure your lines are only one pixel wide
• Use a drop shadow to help separate the text from the background
