The Future of 4K/UHD Acquisition with 12G-SDI Technology

By October 1, 2018News

SDI (Serial Digital Interface) is a family of digital video interfaces first standardized by SMPTE (Society of Motion Picture and Television Engineers) in 1989. While SDI has been the broadcast standard for AV interfaces for decades, the prevalence of 4K, High Dynamic Range (HDR), and high frame rate (HFR) workflows have much higher bandwidth requirements for uncompressed video signals.

Until now, the cabling that supports 4K production was an inconvenient endeavor, demanding four times the amount of cable required for 3G-SDI. A high quality HD signal required a single 3Gbps SDI cable. Currently, that same workflow in 4K requires four separate connections (3Gbps times 4 = 12G)

As camera and routing technology continues to increase resolution, frame rate, and color depth, the cable prerequisite needs to align with carrying a significant amount of data. To help reduce system complexity, the advent of 12Gbps SDI BNC cable and connections have already revealed immediate logistical benefits: less weight, lower cost, and decreased risk of image degradation and signal dropout, while having the bandwidth to handle high-resolution requirements over one 12G-SDI cable. 12G technology offers eight times the bandwidth of normal HD-SDI, and can travel long distances when paired with optical fiber.

Bexel is uniquely positioned and equipped to support 12G-SDI with an arsenal of 12G technology, including:

  • 12G Evertz and AJA Routing Systems
  • 12G Ross Production Switchers
  • 12G Fiber and conversion equipment from AJA and Blackmagic
  • 12G Monitors and scopes from Leader and Boland


With the latest broadcast technology demanding increased bandwidth, higher frame rates, and deep color 4K/UltraHD signals, Bexel is primed to transition your next production to 12G-SDI.
