What does STP stand for in AV terminology when referring to cables?

In audio-visual terminology, STP stands for Shielded Twisted Pair. This type of cabling is commonly used in AV installations due to its ability to minimize electromagnetic interference and crosstalk, which can degrade audio and video signals.

The shielding provides an additional layer of protection, making STP cables ideal for environments where multiple cables are used in close proximity to one another or where there may be sources of electrical interference. This feature enhances the integrity and reliability of the signals transmitted over these cables, which is crucial in professional AV settings where high-quality performance is required.

Other terms listed, such as Standard Transmission Protocol, Specialized Transmission Path, and Signal Transfer Protocol, do not refer to recognized types of cabling or signal transmission practices in the AV industry. Thus, they do not capture the essential characteristics and functions of Shielded Twisted Pair cabling.
