Q1: An analog VGA signal transmitted over a 100-foot cable exhibits ghosting and color bleeding. Which
characteristic of analog video transmission explains this degradation?
A. Digital cliff effect
B. Signal attenuation and impedance mismatch in analog transmission
C. HDCP handshake failure
D. EDID negotiation timeout
Correct Answer: B
Rationale: Analog video signals (such as VGA/RGBHV) are continuous electrical waveforms that degrade
over distance due to signal attenuation (loss of amplitude), capacitive coupling between conductors, and
impedance mismatches that cause signal reflections. Ghosting (faint duplicate images) results from
reflections due to impedance mismatches or poor termination. Color bleeding occurs when high-
frequency chrominance signals attenuate faster than luminance signals. Analog signals degrade
gradually—the longer the cable, the worse the quality. This contrasts with digital signals, which either
work perfectly or fail completely (cliff effect) once the signal falls below the receiver's threshold.
Q2: A digital HDMI signal transmitted over a 50-foot cable either displays perfectly or shows no image at
all. Which term describes this all-or-nothing behavior of digital video?
A. Analog degradation
B. Digital cliff effect
C. Signal dithering
D. Chroma subsampling
Correct Answer: B
,Rationale: The digital cliff effect describes the characteristic behavior of digital signals where the
received signal is either perfect (when the bit error rate is below the correction threshold) or completely
absent/garbled (when errors exceed the correction capability). Unlike analog signals that degrade
gradually with increasing noise or distance, digital signals maintain full quality until a critical threshold is
crossed, after which they fail abruptly. HDMI, DVI, and DisplayPort all exhibit this behavior. The cliff
effect is managed through error detection and correction (EDAC), equalization, and signal boosting, but
once the signal quality falls below the cliff, no image is recoverable without hardware intervention.
Q3: Which video signal type transmits luminance (Y) and chrominance (C) on separate conductors,
reducing color crosstalk compared to composite video?
A. Composite video
B. S-Video (Y/C)
C. Component video (YPbPr)
D. RGBHV
Correct Answer: B
Rationale: S-Video (Separate Video, also called Y/C) transmits luminance (Y, brightness information) and
chrominance (C, color information) on separate conductors within a single cable (typically a 4-pin mini-
DIN connector). By separating these signals, S-Video eliminates the chroma-luma crosstalk that occurs in
composite video, where Y and C are combined on a single conductor. This results in sharper images with
better color definition than composite video, though not as high quality as component video (YPbPr) or
RGBHV, which separate the signal into three or more components. S-Video supports resolutions up to
480i/576i standard definition.
Q4: Which analog video signal type separates the image into three components: luminance (Y) and two
color difference signals (Pb and Pr), providing higher quality than S-Video?
A. Composite video
B. S-Video
C. Component video (YPbPr)
D. VGA (RGBHV)
Correct Answer: C
Rationale: Component video (YPbPr) separates the video signal into three components: Y
(luminance/brightness), Pb (blue color difference), and Pr (red color difference). The green signal is
mathematically derived from Y, Pb, and Pr at the display. This three-wire separation eliminates crosstalk
between color and brightness information, providing significantly better image quality than composite
or S-Video. YPbPr component video supports standard definition through high definition (480i to 1080p)
,and is commonly used in consumer electronics, broadcast equipment, and professional AV systems. It
uses three RCA connectors (typically colored green, blue, and red) or BNC connectors in professional
applications.
Q5: Which digital video interface supports resolutions up to 8K, carries audio, and includes content
protection (HDCP) as a mandatory feature?
A. VGA
B. DVI-D
C. HDMI 2.1
D. S-Video
Correct Answer: C
Rationale: HDMI 2.1 supports resolutions up to 10K (7680×4320 at 30Hz, 4K at 120Hz, 8K at 60Hz) with a
maximum bandwidth of 48 Gbps using Fixed Rate Link (FRL) transmission. HDMI carries uncompressed
digital video, up to 32 channels of audio, Ethernet data (HDMI with Ethernet), and Consumer Electronics
Control (CEC). HDCP (High-bandwidth Digital Content Protection) is mandatory in HDMI
implementations for protected content playback. HDMI 2.1 adds features like Variable Refresh Rate
(VRR), Auto Low Latency Mode (ALLM), and Enhanced Audio Return Channel (eARC). The connector is a
19-pin Type A (standard) or Type C (mini-HDMI).
Q6: Which digital video interface is electrically compatible with HDMI but does not carry audio signals
and has no content protection requirement in its base specification?
A. DisplayPort
B. DVI-D
C. SDI
D. HDBaseT
Correct Answer: B
Rationale: DVI-D (Digital Visual Interface - Digital) uses the same Transition Minimized Differential
Signaling (TMDS) electrical specification as HDMI and is electrically compatible with HDMI through
passive adapters. However, DVI-D carries only video signals—no audio, no Ethernet, and no CEC. HDCP is
optional in DVI (not mandatory as in HDMI). DVI-D uses a 24-pin connector (single-link: 1920×1200 at
60Hz; dual-link: 2560×1600 at 60Hz). DVI-I (Integrated) carries both digital and analog signals, while DVI-
A is analog-only. DVI has been largely superseded by HDMI and DisplayPort in consumer and
professional applications.
, Q7: Which display interface standard developed by VESA supports resolutions up to 16K, carries audio,
USB data, and can daisy-chain multiple displays from a single output?
A. HDMI 2.1
B. DVI-D
C. DisplayPort 2.1
D. VGA
Correct Answer: C
Rationale: DisplayPort 2.1, developed by VESA, supports resolutions up to 16K (15360×8640) with a
maximum total bandwidth of 80 Gbps using UHBR (Ultra High Bit Rate) transmission modes. DisplayPort
carries digital video, audio, and USB 2.0 data. A key feature is Multi-Stream Transport (MST), which
allows daisy-chaining up to four displays from a single DisplayPort output using a hub or daisy-chain
topology. DisplayPort uses a 20-pin connector (full-size) or USB-C (DisplayPort Alt Mode). Unlike HDMI,
DisplayPort was designed primarily for computer-to-display connections rather than consumer
electronics and includes features like panel self-refresh for power savings.
Q8: Which professional broadcast video interface transmits uncompressed digital video over coaxial
cable with BNC connectors, supporting distances up to 300 meters at 3G-SDI rates?
A. HDMI
B. DisplayPort
C. Serial Digital Interface (SDI)
D. DVI
Correct Answer: C
Rationale: Serial Digital Interface (SDI) is a professional broadcast standard (SMPTE 259M, 292M, 424M,
2081, 2082) that transmits uncompressed digital video over 75-ohm coaxial cable with BNC connectors.
SDI supports: SD-SDI (270 Mbps, 300m over RG-6), HD-SDI (1.485 Gbps, 100m), 3G-SDI (2.97 Gbps,
100m), 6G-SDI (5.94 Gbps, 80m), and 12G-SDI (11.88 Gbps, 60-70m over high-quality coax). SDI is robust
over long distances, uses simple locking BNC connectors, carries embedded audio, and has no HDCP—
making it ideal for broadcast, live production, and professional AV. Unlike HDMI, SDI does not support
consumer content protection, which is advantageous in professional workflows.
Q9: Which signal distribution technology transmits uncompressed HD video, audio, Ethernet, power
(PoH), and control signals over a single Cat5e or Cat6 cable up to 100 meters?
A. HDMI direct cable
