A yellow coaxial cable is commonly used to transmit composite video signals. It is easily identifiable by its yellow RCA connector.
In more detail:
-
Purpose: The primary use of a yellow coaxial cable is for transmitting standard-definition composite video signals. This type of signal combines all the video information (brightness, color, and synchronization) into a single channel.
-
RCA Connector: The yellow color specifically refers to the plastic surrounding the RCA connector on the end(s) of the coaxial cable. RCA connectors are also often used for stereo audio (red and white) so the color helps distinguish the video cable. The RCA connector consists of a central pin surrounded by a metal ring.
-
Functionality: When plugged into corresponding yellow RCA jacks on devices like VCRs, DVD players, older gaming consoles, and televisions, the cable carries the composite video signal from the source to the display.
-
Limitations: Composite video offers lower quality compared to component video (red, green, and blue cables) or HDMI because all video information is transmitted in a single channel, leading to potential signal degradation and lower resolution.
-
Alternative Names: While generally referred to as "yellow coaxial cable," it's also accurately described as a "composite video cable" or a "yellow RCA cable".
In summary, a yellow coaxial cable with an RCA connector is specifically designed to transmit composite video signals, commonly found in older A/V setups.
