First, we need to understand what SDI is. The so-called SDI, English name SerialDigitalInterface, it is actually an interface type, that is, digital serial interface.
SDI interface can be broadly divided into SD-SDI (270Mbp, SMPTE259M), HD-SDI (1.485Gbps, SMPTE292M), 3G-SDI (2.97Gbps, SMPTE424M) three, from this division criteria can be seen, the rate is an important index.
HD-SDI is a high-definition digital component serial interface. HD-SDI is a real-time, uncompressed, high-definition broadcast-grade camera. It is another technological advancement in the field of security monitoring, providing high-definition image source equipment for the monitoring center. The HD-SDI camera is a high-definition real-time camera that transmits uncompressed digital video over a 75-ohm coaxial cable based on the SMPTE (Society of Motion Picture and Television Engineers) serial link standard.
The 3G-SDI signal has been widely used in the broadcast and television industry. With the continuous development of the security industry, its advantages of high-rate uncompressed digital data have gradually been tapped. Currently, a large number of 3G-SDI series products have been introduced on the market, including SDI conversion equipment. , SDI digital switching matrix devices and SDI distributors. These devices all use 3G signals and are also compatible with 1.5G signals for long-distance transmission to meet the diverse needs of users.
What is the specific difference between 3G-SDI and HD-SDI?
HD-SDI optical transceiver design and production is a highly reliable, high-performance serial digital optical transmission device suitable for the television industry. The signal format is from 19.4Mbps to 1.485Gbps. The system supports SMPTE292, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M and DVB-ASI. (EN50083-9) and other digital television format signals, to meet the requirements of industrial-grade products. 3G-SDI ultra-high-definition digital video optical transceiver is an upgraded version of the HD-SDI optical transceiver, the signal format from 19.4Mbps to 2.97Gbps, the system supports SMPTE424M, Signals in digital television formats such as SMPTE292M, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M, and DVB-ASI (EN50083-9).
With the advent of high-definition (HD) video standards such as 1080i and 720P, the interface has been adjusted to handle higher 1.485 Gbps data rates. The 1.485-Gbps serial interface is commonly referred to as the HD-SDI interface and is defined by SMPTE 292M. It uses the same 75 ohm coaxial cable. SMPTE approved a new standard called SMPTE 424M. On the same 75 ohm coaxial cable, the SDI data rate doubled to 2.97 Gbps. This new standard, also known as 3-Gbps (3G) SDI, supports higher resolution image quality such as 1080P and digital cinema. At present, the highest rate digital product is 7K-SDI.
