UHDI Fundamentals: ‘UHDI’ Bleeding-edge Entertainment Applications, Part 1
October 10, 2024 | Anaya Vardya, American Standard CircuitsEstimated reading time: 1 minute
As soon as we cross below the 1-mil (0.001") line width threshold, we need to stop talking in terms of mils and ounces and begin talking in terms of microns. For reference, a 3-mil trace is 75 microns, so a 1-mil trace is 25 microns. In general terms, ultra high density interconnect refers to line and spaces on a printed circuit board that are sub-25 micron. In the context of this article, ultra high-definition interconnect (UHDI) refers to the technology and infrastructure used to transmit and connect ultra high-definition signals, typically 4K, 8K, or even higher resolutions, across devices like displays, cameras, servers, and processors. Bleeding-edge UHDI applications push the limits of current interconnect technologies by requiring massive bandwidth, ultra-low latency, and advanced data handling capabilities to handle the enormous data loads that UHDI generates.
Here are some bleeding-edge UHDI applications across the entertainment industries:
8K and 16K Live Broadcasting
- Sports broadcasting: UHDI technology is critical for live 8K and 16K broadcasting of sports events, where high frame rates (60–120 fps) are required along with high dynamic range (HDR) and wide color gamut (WCG). This demands reliable high-bandwidth interconnects such as HDMI 2.1, DisplayPort 2.0, or even fiber optics.
- Remote broadcasting: Ultra-high-definition video content is streamed from cameras to control rooms or remote viewers in real-time. This requires very high-speed interconnects with ultra-low latency and no loss of signal quality over long distances.
- High-resolution cinematography: Filmmakers are increasingly shooting in 8K and 16K resolutions, enabling ultra-detailed footage with unprecedented sharpness and visual fidelity. UHDI allows seamless transfer of these massive files between cameras, storage systems, and editing suites. High-bandwidth interconnects like Thunderbolt 4 and PCIe 5.0 help handle enormous data streams without compromising on speed or quality.
- eSports broadcasting: eSports tournaments often rely on UHDI to stream 4K and 8K content to global audiences. Multiple UHD camera angles, high frame rates, and ultra-low latency are essential to providing a smooth and immersive experience for viewers.
