Section 1: AV Fundamentals & Signal Management (15 Questions)
Q1: A technician is troubleshooting a video signal that appears grainy and has color bleeding on
a display. The source is outputting 1080i60, but the display is native 1080p60. What is the most
likely cause of the image quality issue?
A. The display requires HDCP 2.2 but the source only supports HDCP 1.4
B. The interlaced signal is not being properly deinterlaced before display
C. The HDMI cable exceeds the 15-foot maximum recommended length
D. The source and display have incompatible EDID data causing resolution mismatch
Correct Answer: B
Rationale: Interlaced signals (1080i) must be deinterlaced to progressive (1080p) for proper
display on progressive-native screens. Poor deinterlacing causes artifacts like graininess and
color bleeding. While cable length (C) can cause signal degradation, it typically results in
sparkles or dropouts, not interlacing artifacts. EDID issues (D) would cause resolution
mismatches or no signal, not quality degradation.
Q2: Which color space is most commonly used in broadcast video and employs chroma
subsampling to reduce bandwidth while maintaining perceived image quality?
A. RGB 4:4:4
B. YUV 4:2:0
C. CMYK
D. sRGB
Correct Answer: B
Rationale: YUV (YCbCr) with 4:2:0 chroma subsampling is the broadcast standard, reducing
chroma data to 25% of original while preserving luma detail that human vision prioritizes. RGB
,2
4:4:4 (A) uses full bandwidth for all channels. CMYK (C) is for print, not video. sRGB (D) is a
color gamut standard, not a color space encoding method.
Q3: An integrator needs to distribute a 4K@60Hz 4:4:4 HDMI signal to three displays 75 feet
away. Which solution maintains signal integrity without compression?
A. Standard HDMI cables with signal boosters at 25-foot intervals
B. HDMI over HDBaseT extenders using Category 6a cable
C. Fiber optic HDMI cables with optical-to-electrical converters
D. HDMI distribution amplifier with three 25-foot HDMI outputs
Correct Answer: C
Rationale: 4K@60Hz 4:4:4 (18 Gbps) exceeds HDBaseT's 10.2 Gbps bandwidth limit (B) and
HDMI's reliable distance (A, D). Fiber optic HDMI (C) supports 18 Gbps+ over 100+ feet
without compression or signal degradation. Per Extron standards, optical solutions are required
for uncompressed 4K distribution beyond 35 feet.
Q4: What is the primary function of EDID (Extended Display Identification Data) in an AV
system?
A. To encrypt content between source and display using HDCP protocols
B. To communicate display capabilities and preferred timings to the source device
C. To control display power states and input switching via CEC commands
D. To compress video signals for transmission over limited bandwidth cables
Correct Answer: B
Rationale: EDID is a data structure (typically 128-256 bytes) stored in display EEPROM that
communicates supported resolutions, refresh rates, color spaces, and audio capabilities to
sources. HDCP (A) handles encryption separately. CEC (C) is a distinct control protocol. EDID
does not compress video (D); it negotiates capabilities.
Q5: A system shows "HDCP Error" when connecting a Blu-ray player to a projector through an
HDMI splitter. The projector works fine when connected directly. What is the most likely cause?
A. The splitter is not HDCP-compliant and breaks the authentication chain
B. The projector's EDID does not support the Blu-ray player's maximum resolution
C. The HDMI cable between splitter and projector is defective
D. The Blu-ray player is outputting an analog signal incompatible with HDMI
, 3
Correct Answer: A
Rationale: HDCP requires end-to-end authentication; non-compliant splitters (or "HDCP
strippers") interrupt the handshake between source and sink. Per Extron troubleshooting
protocols, always verify HDCP compliance on distribution equipment. EDID issues (B) cause
resolution problems, not HDCP errors. Cable defects (C) cause physical layer issues. Blu-ray
players don't output analog via HDMI (D).
Q6: Which signal type transmits analog video with separate luminance and chrominance
channels, providing better quality than composite video?
A. VGA (RGBHV)
B. Component Video (YPbPr)
C. S-Video (Y/C)
D. DVI-A
Correct Answer: B
Rationale: Component video (YPbPr) separates luminance (Y) and two color difference signals
(Pb, Pr), eliminating chroma/luma crosstalk inherent in composite. While S-Video (C) separates
Y/C, component provides superior quality with higher bandwidth. VGA (A) uses RGB, not
YPbPr. DVI-A (D) is digital-to-analog adapter format, not a signal type.
Q7: An AV designer needs to calculate the required pixel clock for a 1920×1080 @ 60Hz display
with CVT-RB (Reduced Blanking) timing. Which factor is NOT required for this calculation?
A. Horizontal resolution including blanking pixels
B. Vertical resolution including blanking lines
C. Color depth per pixel (8-bit, 10-bit, etc.)
D. Refresh rate in Hz
Correct Answer: C
Rationale: Pixel clock = (Total Horizontal Pixels × Total Vertical Lines × Refresh Rate). Color
depth (C) affects data rate (pixel clock × bits per pixel) but not the pixel clock frequency itself.
Horizontal blanking (A), vertical blanking (B), and refresh rate (D) are all required timing
parameters per VESA CVT standards.
Q8: What is the maximum recommended cable length for reliable HDMI 2.0 (18 Gbps) signal
transmission using passive copper cables in a commercial installation?
A. 3 meters (10 feet)
B. 7.5 meters (25 feet)
