Which connector type is primarily used for high-quality video transmission?

The choice of HDMI as the connector type primarily used for high-quality video transmission is well founded due to its advanced capabilities over other options. HDMI (High-Definition Multimedia Interface) supports uncompressed video and multi-channel audio, providing a higher bandwidth that allows for the transmission of high-definition content while maintaining optimal picture and sound quality.

HDMI can handle resolutions up to 4K and beyond, making it suitable for modern displays and televisions. It also supports additional features like deep color, 3D video, and enhanced audio formats, which further enhance the viewing experience. In contrast, the other connector options generally lack the comprehensive high-definition capabilities that HDMI offers.

For example, USB can transmit video under specific protocols but is not primarily designed for video transmission and may not deliver the same quality. S-video, while providing better quality than composite, does not support higher resolutions and lacks the audio transmission capabilities that HDMI offers. Composite video, the lowest in quality among these options, encodes video information into a single channel, significantly reducing the clarity and detail of the image. Therefore, HDMI stands out as the optimal choice for high-quality video transmission.
