What is an SDI signal?

Serial Digital Interface (SDI) is a standard for the delivery of digital video with coaxial cable. SDI uses a standard 75-ohm cable, which is the same cable used for most home television installations. In the SDI standard, signals are uncompressed and self-synchronizing between the transmitter and the receiver.

What resolution does SDI support?

576i
SD-SDI (SMPTE 259M) 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 SDI and HD-SDI?

SD-SDI: The SD-SDI standard support the 270 Mb/s bit rate. HD-SDI: The standard known as the HD Serial Digital Interface (HD-SDI) is standardized in SMPTE 292M; Although this standard is known as the 1.5 Gb / s interface, the bit rates supported by HD-SDI are actually 1.485 Gb / s and 1.485 / 1.001 Gb/s.

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.

Does HD-SDI support 4K?

Quad-Link HD-SDI supports both DCI 4K and UHD 4K. The maximum quality supported by Quad-Link HD-SDI is 10-bit 4:2:2 at 30p. HD-SDI is a proven and extremely reliable signal for HD video, which is probably why Quad-Link HD-SDI is the most common way of distributing 4K on professional broadcast equipment.

How far can an SDI signal travel?

about 100 meters
Cabling and Loss HD-SDI is regularly transmitted over low-loss digital video grade RG6-style coaxial cable up to a nominal maximum distance of about 100 meters.

Do I need an SDI port?

SDI is a professional video signal that is preferred in production environments because of its longer range (up to 300 feet) and reliability. If you’re in an environment in which your cable could be unplugged or tripped over (which should also be taped down anyway), SDI connections are ideal.

Is 12G SDI 4K?

The 12G SDI standard was introduced simultaneously with the 6G SDI interface in 2015. Since higher bitrates are part of the standard, 12G SDI supports 4K 60 from a single link and 8K 30 from a dual. …

How far can you run 12G SDI?

You may wonder just how far you can go with 12G cables, as distances of well more than 100 feet are easily accomplished. One manufacturer states that 100 meters (325 feet) is possible with its modestly sized cable and precision connectors, so 12G cabling is definitely in the realm of the possible.

What does SDI stand for in SDI-12?

SDI-12 is a standard for interfacing data recorders with microprocessor-based sensors. SDI-12 stands for serial/digital interface at 1200 baud. This document describes the electrical . interface, the communications protocol, and the timing requirements for SDI-12 data recorders .

When was the serial digital interface ( SDI ) standardized?

SDI: Serial Digital Interface (SDI) is a family of digital video interfaces first standardized by SMPTE (Society of Motion Picture and Television Engineers) in 1989. For example, ITU-R BT.656 and SMPTE 259M are defined for broadcast-grade video. SD-SDI: The SD-SDI standard support the 270 Mb/s bit rate.

What is the bit rate of HD SDI?

HD-SDI: The standard known as the HD Serial Digital Interface (HD-SDI) is standardized in SMPTE 292M; Although this standard is known as the 1.5 Gb / s interface, the bit rates supported by HD-SDI are actually 1.485 Gb / s and 1.485 / 1.001 Gb/s.

What kind of coaxial cable does HD-SDI use?

With the advent of high definition (HD) video standards such as 1080i and 720P, interfaces have been adapted to handle higher 1.485Gbps data rates, and the 1.485-Gbps serial interface, commonly referred to as the HD-SDI interface, is defined by the SMPTE292M, It uses the same 75-ohm coaxial cable.
