{{short description|Electrical or optical connectors for carrying audio and video signals}}
{{
'''Audio connectors''' and '''video connectors''' are [[electrical connector|electrical]] or [[optical fiber connector|optical connectors]] for carrying [[audio signal|audio]] or [[video signal]]s. '''Audio interfaces''' or '''video interfaces''' define physical parameters and interpretation of signals. For [[digital audio]] and [[digital video]], this can be thought of as defining the [[physical layer]], [[data link layer]], and most or all of the [[application layer]]. For [[analog audio]] and [[analog video]] these functions are all represented in a single signal specification like [[NTSC]] or the direct [[Loudspeaker|speaker]]-driving signal of analog audio.
Physical characteristics of the electrical or optical equipment include the types and numbers of wires required, voltages, frequencies, optical intensity, and the physical design of the connectors. Any data link layer details define how application data is encapsulated (for example for [[synchronization]] or [[error-correction]]). Application layer details define the actual audio or video format being transmitted, often incorporating [[codec]]s not specific to the interface, such as [[PCM]], [[MPEG-2]], or the [[DTS Coherent Acoustics codec]]. In some cases, the application layer is left open; for example, [[HDMI]] contains an [[Ethernet]] channel for general data transmission.

[[DisplayPort]] is a digital display interface standard (approved May 2006, current version 1.4 published on March 1, 2016). It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system.
The video signal is not compatible with [[Digital Visual Interface|DVI]] or [[High-Definition Multimedia Interface|HDMI]], but a DisplayPort connector can pass these signals through. DisplayPort is a competitor to the HDMI connector, the [[de facto]] digital connection for high-definition consumer electronics devices.

VIVO is found predominantly on high-end [[ATI Technologies|ATI]] video cards, although a few high-end [[NVIDIA]] video cards also have this port. VIVO on these graphics cards typically supports [[Composite Video|Composite]], [[S-Video]], and [[Component video|Component]] as outputs, and composite and S-Video as inputs. Many other video cards only support component and/or S-Video outputs to complement [[Video Graphics Array]] or [[Digital Visual Interface|DVI]], typically using a component breakout cable and an S-Video cable.
