Video Resolution | Transmission Distance |
---|---|
SD 480i / 576i (270Mbps) | 300 meters |
HD 720p / 1080p@24/25/30fps (1.485Gbps) | 200 meters |
Full HD 1080p@50/60fps (2.97Gbps) | 100 meters |
※ For transmitting HD signals (720p, 1080i, 1080p@24/25/30Hz), use coaxial cables with at least 1.5Gbps (1500MHz) bandwidth.
※ For Full HD signals (1080p@50/60Hz), use coaxial cables with at least 3Gbps (3000MHz) bandwidth.
※ It is recommended to use high-quality 75-ohm coaxial cables and BNC connectors. Using low-quality coaxial cables may result in signal degradation, reduced transmission distance, and instability.
※ The SDI interface does not support 480p and 576p resolutions.
※ The UPF350 is a signal interface converter and does not alter resolution. The SDI output resolution and frequency match the HDMI input signal. If your SDI monitor or device does not support the HDMI input resolution and frequency, no display will appear.
