Is 3G-SDI and HD-SDI the same?
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.
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.
Does HD-SDI support 1080P?
SDI is a professional digital video standard developed for broadcast video. There are 4 common SDI standards. The original SDI supports 480i video, HD-SDI increased the supported resolution to 1080i/720p. 3G-SDI supports 1080p, and 6G-SDI supports up to 4K at 30Hz.
How far can you run HD-SDI?
about 100 meters
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.
Is HD-SDI 3G?
The 1.485Gbps serial interface is usually called as HD-SDI interface, defined by SMPTE292M, and uses the same 75 ohm coaxial cable. This new standard is also called 3-Gbps (3G) SDI, which supports higher-resolution image quality such as 1080P and digital cinema.
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.
Which is better dual link or 3G HD-SDI?
3G HD-SDI uses a higher data rate to send more information per second. The capabilities are similar to Dual-Link but the confusion of two separate cables is removed. All information is carried on the single cable. Dual Stream 3G HD-SDI Signal
What is the difference between HD SDI and HD-SDI?
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.
What is the bit rate of 3G SDI?
3G-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. These levels are called A, B-DL, and B-DS.
What’s the difference between 6g and 6G-SDI?
6G-SDI: This standard defines a bit-serial data structure, electrical signal and coaxial cable interface for the transport of signals with a total payload of 5.940 Gb/s or 5.940/1.001 Gb/s. This standard also specifies the electrical and physical characteristics of coaxial cables and connectors.
