![]() It doesn’t support HD content or progressive scan images. However, even component cables have had their day – high-resolution HDMI is now typically the connection of choice for the latest generation of audio-visual equipment.Ī composite video cable - also known as an RCA or “yellow plug” cable - is an old standard that transfers a video signal through one cable and connector. The newer component cable format was designed to work with modern high-definition devices. Old-style composite cables are no longer supported by most devices. But that’s where the similarities between the two formats end. This is known as YPbPr component video.Ĭomponent and composite audio-visual connection cables both transmit video via an analog signal. Component cables use the red and white audio connectors, but they divide the video into three components: one for luma (brightness) and two for color information. Composite RCA cables feature one yellow connector for video, and red and white connectors for audio. In a home theater, analog signals usually use one of two different connector types: composite or component. Older devices use analog signals, while newer ones use digital signals, and they each have different types of connectors to get everything to work together. There are an array of different connector types for audio visual equipment, but basically they all fall into two camps: digital and analog.
