![]() Carries standard definition video and does not carry audio on the same cable.Ĭomponent. RCA jack, normally yellow (often accompanied with red and white for right and left audio channels respectively) Often designated by the CVBS acronym, meaning "Color, Video, Blank and Sync". S/PDIF (Sony/Philips Digital Interconnect Format). Computers and other equipment sometimes use Microsoft-Intel color coding scheme, especially when there are multiple input/output plugs.Ħ.35 mm TRS audio jack (shielded twisted pair), Often unmarked on consumer audio equipment since it is so common, or labelled with headphones symbol or as "line out". Interfaces and their connectors Interface This means that in some cases not all components with physically compatible connectors will actually work together.Īnalog A/V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise. Some types of connectors are used by multiple hardware interfaces for example, RCA connectors are used both by the composite video and component video interfaces, but DVI is the only interface that uses the DVI connector. In some cases, the application layer is left open for example, HDMI contains an Ethernet channel for general data transmission. Application layer details define the actual audio or video format being transmitted, often incorporating codecs not specific to the interface, such as PCM, MPEG-2, or the DTS Coherent Acoustics codec. Any data link layer details define how application data is encapsulated (for example for synchronization or error-correction). 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. For analog audio and analog video these functions are all represented in a single signal specification like NTSC or the direct speaker-driving signal of analog audio. 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. Audio interfaces or video interfaces define physical parameters and interpretation of signals.
