1What is the resolution of 1080p high-definition video?
A.1920 x 1080
B.1280 x 720
C.3840 x 2160
D.720 x 480
Explanation: 1080p (Full HD) has a resolution of 1920 x 1080 pixels with progressive scanning. The 1080 refers to the number of vertical lines (active picture height). 1080i shares the same pixel count but is interlaced.
2In video scanning terminology, what does the 'i' in '1080i' indicate?
A.Interlaced scanning
B.Improved color
C.Integer frame rate
D.Internal sync
Explanation: The 'i' stands for interlaced scanning, in which each frame is divided into two fields containing alternating odd and even lines. The 'p' suffix indicates progressive scanning, where every line is drawn in sequence within a single pass.
3What is the standard pixel resolution of 4K UHD (Ultra High Definition) broadcast video?
A.3840 x 2160
B.4096 x 2160
C.2560 x 1440
D.1920 x 1080
Explanation: 4K UHD television uses 3840 x 2160, exactly four times the pixel count of 1080p HD (two times horizontally and vertically). The 4096 x 2160 resolution is DCI 4K, used in digital cinema rather than broadcast/consumer UHD.
4What is the aspect ratio of standard HDTV and UHDTV video?
A.16:9
B.4:3
C.21:9
D.1.85:1
Explanation: HDTV and UHDTV use a 16:9 (1.78:1) widescreen aspect ratio. Legacy standard-definition television used 4:3. Cinema formats such as 1.85:1 and 2.39:1 are wider than the broadcast 16:9 frame.
5The NTSC frame rate of '30 fps' is more precisely what value for color video?
A.29.97 fps
B.30.000 fps
C.25.00 fps
D.24.00 fps
Explanation: NTSC color video runs at 29.97 fps (30/1.001), a slight offset introduced to keep the color subcarrier from interfering with the audio carrier. The original monochrome NTSC was exactly 30 fps before color was added.
6How many fields make up one complete frame in an interlaced video signal?
A.Two
B.One
C.Three
D.Four
Explanation: In interlaced video, each frame consists of two fields: one containing the odd-numbered lines and one containing the even-numbered lines. The two fields are scanned in rapid succession and combined by the display to form a full frame.
7Which film-originated frame rate is commonly used to give video a 'cinematic' look?
A.24 fps
B.50 fps
C.60 fps
D.120 fps
Explanation: 24 fps is the traditional motion-picture film rate and is widely used in video production for a cinematic appearance. Higher rates such as 50 and 60 fps render motion more smoothly and are favored for sports and fast action.
8The PAL television standard uses what nominal frame rate?
A.25 fps
B.24 fps
C.29.97 fps
D.30 fps
Explanation: PAL (and SECAM) systems use 25 fps with 625 lines, derived from the 50 Hz mains frequency common in those regions. NTSC, used in 60 Hz regions, runs at 29.97 fps with 525 lines.
9How many active scan lines does the NTSC standard-definition system use per frame?
A.480
B.525
C.576
D.625
Explanation: NTSC has 525 total lines per frame but only about 480 are active (visible) picture lines; the remainder fall in the vertical blanking interval. PAL/SECAM has 625 total lines with roughly 576 active.
10What does the vertical blanking interval (VBI) in an analog video signal provide time for?
A.The electron beam to return from bottom to top of the screen
B.Color burst generation only
C.Audio multiplexing
D.Aspect ratio conversion
Explanation: The vertical blanking interval is the period during which the scanning beam retraces from the bottom of the raster back to the top to begin the next field or frame. It also historically carried ancillary data such as closed captions and test signals.
