General Technology Flashcards

Which display technology uses organic compounds that emit light when an electric current is applied?

Answer: OLED

OLED (Organic Light-Emitting Diode) uses organic compounds that produce light directly, eliminating the need for a backlight.

In AV system design, what does 'latency' refer to?

Answer: The delay between input and output of a signal

Latency is the time delay between when a signal is sent and when it is received or processed, critical in live event and video conferencing setups.

What is the primary purpose of a signal extender in an AV installation?

Answer: To transmit AV signals beyond the native cable length limit

Signal extenders allow AV signals to travel beyond the standard cable distance limits, often using HDBaseT, fiber, or IP-based transmission.

Which color model is used for light-emitting displays such as monitors and projectors?

Answer: RGB

RGB (Red, Green, Blue) is an additive color model used by displays that emit light, combining colors to produce white at full intensity.

What does the term 'gain' mean in the context of a projector screen?

Answer: The ratio of light reflected compared to a standard reference white

Screen gain is a measure of reflectivity compared to a standard magnesium carbonate white reference; a gain above 1.0 reflects more light toward the viewer.

In networking, what does 'bandwidth' measure?

Answer: The maximum data transfer rate of a network connection

Bandwidth refers to the maximum rate at which data can be transmitted over a network connection, typically measured in Mbps or Gbps.

Which standard governs the interoperability of control systems in AV environments through a common API?

Answer: REST API over TCP/IP

REST APIs over TCP/IP have become the dominant standard for AV control system interoperability, allowing devices from different manufacturers to communicate.
