Question 1

What does HDCP protect in an AV system?

Accepted Answer

Copyrighted digital content transmitted over HDMI or DVI

Answer

HDCP (High-bandwidth Digital Content Protection) is a digital copy protection standard that encrypts the content signal between a source and a display to prevent unauthorized copying.

Question 2

A video matrix switcher is primarily used to:

Accepted Answer

Route any video input to any video output independently

Answer

A video matrix switcher allows any input signal to be routed to any one or multiple outputs simultaneously and independently, providing flexible signal distribution.

Question 3

What is chroma subsampling 4:2:0 used for?

Accepted Answer

Reducing bandwidth by sampling color at a lower resolution than luma

Answer

4:2:0 chroma subsampling reduces file size and bandwidth by sampling the color (chroma) information at one-quarter the rate of the luminance (luma), exploiting the human eye's lower sensitivity to color detail.

Question 4

What is the primary function of a distribution amplifier (DA) in an AV system?

Accepted Answer

To split and amplify a single signal to multiple outputs without degradation

Answer

A distribution amplifier takes a single input signal, amplifies it, and distributes it to multiple outputs while maintaining signal integrity across all destinations.

Question 5

Which video interface standard uses BNC connectors and is common in professional broadcast and long-distance installations?

Accepted Answer

SDI (Serial Digital Interface)

Answer

SDI (Serial Digital Interface) uses coaxial cable with BNC connectors and is the professional broadcast standard capable of carrying uncompressed digital video over long distances.
