Question 1

Interlace scanning is the process of splitting a frame of video into two fields.

Accepted Answer

Interlace scanning splits each frame into two fields, one containing the even lines and the other containing the odd lines.

Question 2

If the displayed image is kept at the same size, an increase in resolution would decrease the detail in the image.

Accepted Answer

An increase in resolution would actually increase the detail in the image. More pixels would be available, allowing for finer and clearer details to be displayed.

Question 3

Digital Broadcast, Cable, and Satellite broadcasting all use the same method of modulation.

Accepted Answer

Digital Broadcast, Cable, and Satellite broadcasting may use different methods of modulation to transmit data. For example, cable might use QAM (Quadrature Amplitude Modulation), while satellite often uses PSK (Phase Shift Keying), and terrestrial digital broadcast might use COFDM (Coded Orthogonal Frequency Division Multiplexing).

Question 4

Interlaced scanned images have greater apparent clarity of detail than an equivalent progressively scanned image.

Accepted Answer

Interlaced scanning alternates between displaying odd and even lines, which can lead to motion artifacts and reduced clarity, especially in fast-moving images, whereas progressive scanning displays all lines in sequence, providing a clearer and more detailed image.

Question 5

While the US government mandated a change to digital television, it has not ordered that all television broadcasting must be High Definition.

Accepted Answer

The US government mandated a change to digital television but did not require broadcasters to transition to high definition.

Question 6

This non-government organization, comprised of over 165 member countries, sets technical standards for scientific, technological, and economic activity.&#10;A) SMPTE&#10;B) ISO&#10;C) ATSC&#10;D) EBU

Accepted Answer

ISO (International Organization for Standardization) is a non-government organization responsible for setting technical standards for scientific, technological, and economic activity. It has over 165 member countries. SMPTE (Society of Motion Picture and Television Engineers), ATSC (Advanced Television Systems Committee), and EBU (European Broadcasting Union) are industry organizations specifically focused on media technology and broadcasting standards.

Question 7

The criteria that creates a standard include .&#10;A) how many pixels make up an image&#10;B) the scanning process used to display the image&#10;C) the number of frames displayed per second&#10;D) all of the above

Accepted Answer

All three options, how many pixels make up an image, the scanning process used to display the image, and the number of frames displayed per second, are factors that contribute to the overall standard of image or video quality. Therefore, D is the best choice.

Question 8

The represents the width of the image compared to&#10;A) format&#10;B) resolution&#10;C) aspect ratio&#10;D) both B & C

Accepted Answer

The aspect ratio represents the proportional relationship between the width and height of an image or screen, while resolution refers to the number of pixels in an image. The format is a more general term that can refer to the size, shape, or layout of an image, but it does not directly relate to the width of the image. Therefore, the best answer is C, as the aspect ratio is directly related to the width of the image.

Question 9

The frame rate represents what is known as the ________ of the image.&#10;A) delineation&#10;B) depth of focus&#10;C) temporal resolution&#10;D) reciprocity construct

Accepted Answer

The frame rate represents the temporal resolution of the image, or how quickly the image is updated and refreshed. This is important in capturing fast-moving objects, as a lower frame rate can result in motion blur or choppiness in the image. The other options are not accurate descriptions of the role of frame rate in image capture.

Question 10

Which of the following is considered a digital television category (not standard)?&#10;A) SDTV&#10;B) HDTV&#10;C) EDTV&#10;D) all of the above

Accepted Answer

All of the options listed are digital television categories that differ from the traditional standard definition television (SDTV) format. HDTV offers higher resolution and a wider aspect ratio, EDTV offers increased resolution but not as high as HDTV, and both are considered digital formats.
