Published May 03, 2026

Serial Digital Interface mit einer Datenrate von 12 Gb/s. Flächen repräsentieren die Verhältnisse der jeweiligen Datenrate. 12G-SDI ist eine Schnittstelle für die serielle Übertragung eines UHD/4K-Signals. Mit dieser Schnittstelle kann man also UHD-Signale mit nur einem BNC-Kabel übertragen.

Also know, what does 12G-SDI mean?

12 Gigabits per second

Secondly, is 12G-SDI 4K? 12G-SDI offers eight times the bandwidth of normal HD-SDI and offers the simplicity of single cable connectivity. 12G-SDI has the ability to handle high frame rate and deep color 4K/UltraHD signals over a single cable, including up to 100/120fps.

Then, what resolution is 12G-SDI?

4Kp60 resolution

What is SDI video signal?

Serial Digital Interface (SDI) is a standard for digital video transmission over coaxial cable. A signal in SDI can contain up to four independent digital audio signals along with the video signal. SDI also stands for the Strategic Defense Initiative, a U.S. space defense initiative.

Is HDMI better than SDI?

When comparing SDI to HDMI specs, HDMI 2.0 is the clear theoretical winner of image quality because it surpasses the bandwidth of three SDI cables. SDI is a one-way, multiplexed protocol designed to carry the highest quality video, audio and metadata over a coaxial cable or fiber.

What is the advantage of SDI?

The SDI standard offers uncompressed, latency-free distribution of signals over the coaxial cable with cable lengths that are unrivalled by the competition. SDI also supports ANC (ancillary data) which is used in broadcast systems.

Does SDI carry power?

The CoaXPress standard is another high-speed digital interface, originally design for industrial camera interfaces. The data rates for CoaXPress go up to 12.5 Gbit/s over a single coaxial cable. A 41 Mbit/s uplink channel and power over coax are also included in the standard.

Does 6G SDI support 4K?

6G-SDI uses just one BNC cable to send 10 Bit 4:2:2 4K at 30p or 24p. You will need one BNC cable that supports 6 Gb/s of bandwidth for 6G-SDI. Finding a compatible cable can be tough because cables are not advertised as supporting 6G-SDI since it's not a standard.

Are all SDI cables the same?

Not all coax cables are rated for SDI. Most can carry it. But different coax cable center conductors are different diameters and can carry different signals based on the diameter of the cable.

How far can you run SDI cable?

about 100 meters

Is 3G-SDI and HD-SDI the same?

SMPTE approved the new standard, SMPTE424M, which doubles the SDI data rate to 2.97Gbps over the same 75-ohm coaxial cable and supports higher-resolution images such as 1080P and digital cinema. 3G-SDI is an upgraded version of HD-SDI.

Why is 4K 2160?

A 4K TV simply boosts that pixel count: Usually, 4K refers to a display resolution of 2160p, or 3,840 x 2,160 pixels. That's roughly four times larger than a 1080p picture, hence the term "4K."

How do I convert SDI to HDMI?

Installation of the SDI to HDMI converter step by step
  1. Place the converter on a flat, smooth surface.
  2. Connect the SDI and HDMI cables to the converter in the proper places.
  3. Connect SDI and HDMI cables to the proper devices: SDI to the source device and HDMI to the display device.

What is the difference between 3G-SDI and 12G SDI?

So 3G-SDI simply means it can transfer about 3 gigs of video data per second. 6G can transfer roughly 6 gigs per second, and 12G can transfer roughly 12 gigs per second. Well, if you want higher quality video, then you're going to need a stronger signal.

What is SDI resolution?

The SD-SDI is the first version of the standard and was introduced in 1989. It supports resolutions up to 576i (NTSC and PAL compatible resolutions at 25 frames per second) and four different bitrates: 270 Mbit/s, 360 Mbit/s, 143 Mbit/s, and 177 Mbit/s.

What is the difference between 3G and 12G SDI?

SDI: This standard is known as the 3 Gb/s interface, but the actual bit rates are 2.97 Gb / s and 2.97 / 1.001 Gb / s. 3G-SDI supports several different mapping levels, as described in the SMPTE ST425-1 standard. SDI: The 12G-SDI is an SDI standard developed to support higher resolution, frame rate, and color fidelity.

What is HD-SDI output?

HD-SDI is a high-definition digital component serial interface. HD-SDI is high-definition radio and television camera which is real-time and uncompressed. It is another scientific and technological progress in the security monitoring field. It provides a high-definition image source for the monitoring center.

Is SDI digital?

Serial Digital Interface (SDI) is a standard for the delivery of digital video with coaxial cable. While data speeds up to 3 gigabits per second (Gbps) are possible with SDI, the most common speed is half that at 270 Mbps.

What is the difference between SD and SDI?

What are the differences between SDI and SD signal? SDI stands for Serial Digital Interface and SD stands for Standard Definition. There are people who confuse and refer to the SDI signal when it means SD, this can lead to error since the SDI signal can be SD, HD, 3G, 6G or 12G.

Is SDI cable BiDirectional?

The new Micro Converter BiDirectional SDI/HDMI 3G model even supports camera control so you can use a Blackmagic Pocket Cinema Camera with an ATEM SDI switcher. It even works in reverse and you can connect and control an SDI camera from an HDMI switcher such as ATEM Mini!

What is SDI cable?

Serial Digital Interface (SDI) is a digital video interface that is used for the transmission of uncompressed, unencrypted digital video signals for professional video equipment. Standard SDI cables are terminated with BNC connectors and have a nominal impedance of 75 Ohms.

Is 3G SDI backwards compatible?

SDI is inherently backwards compatible, so even though the camera has a 6G-SDI output, it should work fine with any HD-SDI input device.

Is SDI digital or analog?

SDI is a professional video transmission interface, generally used in broadcast video equipment. SDI and HDMI both support uncompressed digital video transmission, but the HDMI interface to use the 19-line transmission, SDI with the ordinary 75-ohm coaxial line can.

What does SDI mean on my paycheck?

State Disability Insurance

Is DVI or SDI better?

SDI is capable of carrying signals longer distances than DVI, up to 100 feet or more, compared to DVI's 75-foot maximum limitation. SDI is capable of being added to analog equipment without adding more chips to the device, tapping into the audio and video processors directly.
