What was the key achievement of the phonograph?

• First moving image recorder

• First device to record and reproduce sound

• First wireless communication device

NTSC and PAL are examples of:

• Audio formats

• Analog television standards

• Digital codecs

• Camera sensor types

In the broadcast chain, what comes immediately after production (camera capture)?

• Reception

• Transmission

• Distribution

• Editing

ENG stands for:

• Electronic News Gathering

• Enhanced Network Graphics

Interlaced scanning means:

• Two fields create one frame by scanning odd/even lines

• Every pixel is scanned in sequence

• Audio and video are combined in one signal

• The image is scanned at double the frame rate

Which light quality creates softer shadows?

• Hard light

• Point-source light

CRI (Color Rendering Index) measures:

• How bright a light appears in lumens

• How accurately a light reproduces colors

• The Kelvin temperature of a light

• The energy efficiency of a light

What does Kelvin temperature describe in lighting?

• Brightness of a bulb

• Stability of the power source

• Color temperature (warm → cool)

• Angle of the light beam

Why did CMOS replace CCD in most modern cameras?

• CMOS has slower readout but better resolution

• CMOS is faster, cheaper, and more power-efficient

• CCD has less noise in low light

• CCD is easier to manufacture

A photosite on a digital sensor corresponds to:

• A pixel in the final image

• The lens aperture

• A shutter mechanism

• A zoom element
