Mixed Deck — All CBT Topics Flashcards

Which of the following is considered a conflict of interest for a broadcast chief engineer?

Answer: Holding a financial stake in a vendor company whose equipment the engineer specifies

A financial interest in a vendor creates a direct conflict of interest when that engineer has authority over equipment purchasing decisions.

What is the purpose of an automatic exciter changeover system in a broadcast transmitter plant?

Answer: To automatically replace a failed exciter with a standby unit

Automatic exciter changeover detects exciter failure and switches to a standby unit without operator intervention, minimizing on-air downtime.

Which risk mitigation strategy is MOST appropriate for a broadcast station located in a flood-prone region?

Answer: Elevating critical equipment above the 100-year flood plain and installing flood barriers

Physical elevation and flood barriers prevent water from reaching critical equipment, providing proactive protection rather than merely compensating for losses after the fact.

A TV station fails to air the required EAS Required Monthly Test (RMT). What is the most appropriate corrective action?

Answer: Immediately air a makeup RMT at the next opportunity and document the reason for the missed test

Stations should air a makeup RMT as soon as possible and thoroughly document the circumstances of the missed test for their EAS records.

A stakeholder questions the value of professional ethics & standards initiatives. Which response best demonstrates ROI?

Answer: Building a culture of accountability with transparent reporting

Building a culture of accountability with transparent reporting is the correct approach because effective professional ethics & standards in the broadcast technician field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

When a broadcast engineer's professional opinion conflicts with management's decision on a safety matter, the engineer should:

Answer: Document their professional objection and communicate it through proper channels

Engineers should document and formally communicate professional objections to protect both themselves and the public, even while following lawful directives.

In a broadcast studio, what is a 'hot mic' situation?

Answer: A microphone that is open and transmitting audio to the broadcast chain without the talent's awareness

A hot mic is an active, open microphone that is live in the signal chain, potentially capturing and broadcasting audio the talent does not intend to be heard.

When presenting a capital equipment upgrade proposal to station management, which element is MOST critical to include for non-engineering stakeholders?

Answer: Return on investment, risk mitigation, and operational impact in plain language

Management approves budgets based on business value, so ROI, risk reduction, and operational benefits must be communicated clearly without heavy technical jargon.

When a broadcast technician disagrees with a producer's last-minute technical decision that could compromise signal quality, the best approach is to:

Answer: Clearly state the technical risk, document the concern, and defer to the producer's decision if overruled

Technicians should advocate for technical integrity by clearly communicating risks, but must respect the chain of command while protecting themselves with documentation.

A broadcast tower crew identifies a cracked weld on a guy wire anchor during routine inspection. In a risk management framework, this finding should be classified as:

Answer: High risk—structural failure could cause catastrophic tower collapse

A cracked guy wire anchor is a structural integrity failure that can lead to catastrophic tower collapse, endangering personnel and causing total loss of broadcast infrastructure.

Under SBE (Society of Broadcast Engineers) ethics guidelines, a certified engineer should treat proprietary technical information obtained from a client with:

Answer: Strict confidentiality unless legally compelled to disclose

SBE ethics require certified engineers to maintain strict confidentiality regarding proprietary client information.

What is the role of a grandmaster clock in a SMPTE ST 2110 broadcast facility?

Answer: It provides the master PTP reference that all other devices synchronize to

The grandmaster clock is the PTP master reference in the network; all other devices synchronize their internal clocks to it, ensuring consistent timing across the entire IP facility.

What does a vectorscope display in a broadcast environment?

Answer: The chrominance (color) saturation and hue of a video signal

A vectorscope plots color information on a polar display showing hue as angle and saturation as distance from center, allowing engineers to verify accurate color reproduction and legal chroma levels.

A broadcast technician professional discovers a discrepancy during quality assurance & compliance review. What is the most appropriate immediate action?

Answer: Engaging stakeholders collaboratively to align goals and expectations

Engaging stakeholders collaboratively to align goals and expectations is the correct approach because effective quality assurance & compliance in the broadcast technician field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

A technician is offered a gift by a vendor in exchange for recommending their equipment to the station. The ethical response is to:

Answer: Decline the gift to avoid any conflict of interest

Accepting gifts from vendors creates a conflict of interest and compromises the integrity of equipment recommendations.

When conducting a video quality check, a broadcast engineer observes 'luma clipping' in the outgoing signal. What does this indicate?

Answer: The video brightness (luminance) signal is exceeding the maximum legal white level

Luma clipping occurs when the luminance component of the video signal exceeds the legal white level (typically 100 IRE or 700 mV), which can cause issues at the transmitter and violate signal standards.

What is the primary reason broadcast IP networks prefer UDP over TCP for real-time media transport?

Answer: UDP has lower overhead and avoids TCP's retransmission delays, which are unacceptable in live broadcast

UDP's connectionless, low-overhead nature avoids TCP's retransmission and congestion-control mechanisms, which would introduce unacceptable latency and jitter in live broadcast applications.

What is the role of inductance in an AC circuit?

Answer: Opposes changes in current

Inductance resists changes in current and causes a phase shift between voltage and current in AC circuits.

During a major live event, the executive producer requests a technical change that the broadcast technician knows violates FCC transmission rules. The technician should:

Answer: Refuse the change, clearly explain the regulatory violation, and document the refusal

FCC rule violations cannot be delegated by verbal authorization; the technician must refuse, explain the regulation, and document the interaction to protect themselves and the station.

What is the significance of 'ATSC 3.0' compliance for broadcast television stations transitioning to NextGen TV?

Answer: ATSC 3.0 is an optional next-generation standard; stations must simulcast ATSC 1.0 to maintain required coverage

ATSC 3.0 (NextGen TV) is currently voluntary; stations deploying it must simulcast their ATSC 1.0 signal to maintain required coverage of existing viewers.
