Test your knowledge of AV/IT acronyms

TRUE OR FALSE

1. SDI is an interface that transports standard definition (SD) video content.

2. Internet Protocol (IP) has seven layers: physical, data link, network, transport, session, presentation, and application.

3. POTS and PANS are both real acronyms, not just cookware.

4. AES/EBU is an audio standard also adopted by ANSI. It can be sent via XLR or BNC connectors with AC3 5.1 formatting, and can be embedded into SDI. All of these acronyms actually mean something.


ANSWERS

1.FALSE. While SD is understood to refer to standard definition video resolution, SDI refers to serial digital interface, defined by SMPTE 259M (for SD) and 292M (for HD).

2.FALSE. Those seven layers define the OSI (Open Systems Interconnection) model. IP is the network layer of that model that describes the set of rules governing how data packets are transmitted over the Internet.

3.TRUE. POTS stands for “plain old telephone service,“ and PANS stands for “personal area network,“ which is the interconnection of IT devices within the range of an individual person, typically within a range of 10 meters.

4.TRUE. If you understand the meanings of these acronyms, and the sentence makes sense to you, you are probably an AV/IT professional.
