SDI (Serial digital interface ) is a family of digital video interfaces originally standardized by SMPTE in 1989, defining digital video interfaces used for broadcast-grade video. It is commonly used to transmit uncompressed and unencrypted video signals.
SDI is a signal transport format and BNC is a connector format. SDI utilizes RF coaxial cables which regularly require to use of a BNC Plug connector. Because the signal’s bandwidth can extend on gigahertz range, SDI cables can no longer support this.SDI carries 16 channels of pulse-code modulation or PCM audio and uncompressed video that is itself digital, it must use the proper BNC connector to handle this digital signal.
BNC connector is for a variety of equipment as the signal connections, such as television cables, analog and serial digital interface video signals, aerospace electronics, Radios, nuclear instrumentation, and test equipment. Besides. BNC connects with SDI to allow extended signal bandwidths, SDI is an interface type used on high definition signals, BNC connector is essential with the SDI you are utilizing. It has a rotating ring outside the BNC cable tube that can lock with female connectors. It is usually mounted on monitors to increase the signal accuracy especially those sent by the video adapter.
The different kinds of equipment such as radios and televisions use BNC as the coaxial cable connectors. And SDI uses this cable to accommodate high bandwidth signals. A variety of equipment uses this BNC interface for the transmission of uncompressed or unencrypted digital signals.
It is not good choice to utilize SDI alone as you need a BNC connector for signals with high bandwidth. Thus, it is important to find a proper fit for the BNC Coax cable. You can see kinds of 75ohm BNC connectors and Pre-made 75 Ohm BNC cable assemblies at Superbat. We can provide the custom service for the RF coaxial cable assemblies upon your requirements and the quick turn-around time for your projects. 75ohm BNC cable assembly with Belden 1694A and Belden 1855A for 3G 6G HD SDI Video Camera and Monitor are available.
