Whether you’re filming and editing a promotional video, setting up a security system for a commercial building, or planning to broadcast a live event, you need high-quality audio visual (AV) connections. So what is SDI, and what is it used for?
Serial digital interface (SDI) is a professional AV transmission standard that uses coaxial or fiber optic cables to deliver exceptional, uncompressed video and audio. SDI is used across a wide range of applications, including TV and film production, live broadcasting for virtual events, security and surveillance, and medical imaging.
SDI transmits high-quality audio and visual signals without any compression artifacts, preserving the minute details produced by the original signal.
Latency or “lag” refers to the time it takes from when a packet of data is sent to when it’s received. One of the reasons SDI is so popular in live broadcasting is its minimal latency.
While latency refers to the speed of data transmission, bandwidth refers to the amount of data that can be sent at one time. SDI connections support high data rates, which result in high-resolution video and a smoother user experience.
Each SDI cable carries a signal directly from one device to another, creating an ultra-reliable connection.
SDI connections can transmit video and audio signals over long distances using coaxial cables up to 300 meters with standard-definition SDI.
SDI doesn’t just ensure high-quality images and videos. These connections can also carry multiple channels of embedded audio, streaming high-quality audio and video in tandem.
Over time, a variety of different SDI standards have been developed to support different resolutions and frame rates, including SD-SDI (standard definition), HD-SDI (high definition), 3G-SDI, 6G-SDI, and more.
SDI has integrated error correction mechanisms to minimize disturbances caused by noise interference and enhance reliability and signal stability.
SDI is the standard in both pre-recorded and live broadcasting. From news reporting, to sports, to dramatized television, SDI offers reliable transmission of video and audio signals in multi-camera productions.
SDI is ideal for professional video production as it can distribute uncompressed footage over long distances. It’s also beneficial for video editing as signals can be sent back and forth between various types of equipment including switchers, cameras, and monitors.
SDI is often used in high-end home and commercial security systems. Due to its ability to maintain signal quality when traveling far distances, surveillance footage can be transmitted to monitoring stations with little-to-no degradation.
High-quality imaging is essential in a wide variety of medical settings. For example, endoscopes are often used in screenings and surgical procedures to transmit detailed images into a screen, allowing medical professionals to see accurate, live video of what’s happening inside the patient's body.
In addition to video, SDI can also transmit embedded audio signals over multiple channels. This allows the audio to maintain its quality and synchronize with the accompanying footage through a single cable.
SDI can be used for virtual meetings, allowing users to communicate between remote locations without significant latency or quality issues. This is particularly helpful in large-scale professional settings with multiple participants.
SDI can be effectively utilized in live streaming and event production for virtual and hybrid events. Its seamless application with multiple cameras, screens, and switchers affords exceptional flexibility during live events.
High Definition Serial Digital Interface (HD-SDI) is a version of SDI that can transmit high-definition (HD) video signals via coaxial or fiber-optic cables.
The key difference between SD-SDI and HD-SDI is that they support different resolutions, data rates, and applications. HD-SDI can support higher resolution video, but SD-SDI can transmit audio and video across further distances.
Here’s a breakdown of the differences between SDI and HD-SDI:
When choosing between various interface technologies, it’s important to consider your specific needs, the features that are most important, and relevant applications.
Here’s a brief overview of popular interface technologies that can be incorporated into AV systems:
