Which connector is the standard for SDI video?

Explanation:
SDI video relies on a coaxial connection with a controlled impedance to preserve signal integrity at high data rates. The BNC connector is the standard because it locks securely onto the cable and supports the 75-ohm impedance that SDI signaling uses. This combination—reliable coupling, proper impedance matching, and suitability for long cable runs—has made BNC the go-to connector across SD-SDI, HD-SDI, 3G-SDI, and beyond. Other options don’t fit the needs: RCA carries older, lower-bandwidth composite signals; HDMI uses a different signaling system and connector intended for consumer interfaces; XLR is primarily for audio (and some power or mic use) rather than video.
