What type of connector is often used for Standard Definition Television (SDTV)?

Composite video connectors are widely used for Standard Definition Television (SDTV) because they combine the video signal into a single cable, making them suitable for simpler, older television sets and display systems that do not support higher resolutions. This type of connection transmits the video signal as a single feed comprising brightness and color information. It is typically recognized by the distinctive yellow RCA connector.

While HDMI and DisplayPort are excellent for transmitting high-definition signals and have become standard for modern audio-visual equipment, they are not primarily associated with SDTV. Component video can support higher resolutions than composite and is more commonly used for connecting high-definition devices. However, composite video remains the go-to choice for Standard Definition applications, especially in setups where simplicity and compatibility with older televisions are key.
