    What is SDI?

    SDI stands for Serial Digital Interface (SDI), which was standardized by The Society of Motion Picture and Television Engineers (SMPTE) in 1989. SDI standards are employed for transmission of unencrypted and uncompressed digital video signals in the broadcasting industry. There are different types of SDI standards that have been developed to support different resolutions and speeds. The following are the popular ones among them, along with their SMPTE standards:
    • SD-SDI (SMPTE 259M)
    • ED-SDI (SMPTE 344M)
    • HD-SDI (SMPTE 292M)
    • Dual Link HD-SDI (SMPTE 372M)
    • 3G-SDI (SMPTE 424M, 424M:2012)
    • 6G-SDI (SMPTE ST-2081)
    • 12G-SDI (SMPTE ST-2082)

    What is HD-SDI and Why Are They Popular in the Surveillance Industry?

    HD-SDI Stands for High Definition Serial Digital Interface and it is widely adopted by the surveillance industry. This is why it is quite common to find HD-SDI security systems comprising cameras, SDI video transmitters and receivers, and coaxial cables. 
     
    Introduced by SMPTE in 1998, this standard was developed to support the HD resolution (720p and 1080i). It can support up to 1.5 Gbit/s bitrates. The 1.5 Gbit/s bitrates are again distinguished into two versions - 1.485/1.001 Gbit/s and 1.485 Gbit/s. Of this, 1.485/1.001 Gbit/s has been created with a factor of 1.001 to support the frame rates of 29.97 Hz, 59.94 Hz, and 23.98 Hz for video signals. This standard supports various NTSC systems - some of which are older, and developed before 1998. VERSITRON provides HDI to SDI Fiber Converters in different specifications. All of our HD-SDI video transmitters and recorders are compatible with various SDI standards.
     
    In recent years, these systems have gained immense popularity in the surveillance industry due to the following reasons:
    • HD-SDI systems are often mistaken as a high-resolution analog solution, whereas it is a digital video standard. It uses coaxial cables as well as BNC connectors to process high definition digital signals. HD-SDI systems are also compatible with analog systems and provide easy upgrading. This upgrade can be performed by replacing the input and output products. This helps cut down on cabling, and improve efficiency while cutting down on labor costs. You can choose from various HD-SDI converters available from us for this upgrade.
    • HD-SDI converters are proven to transport latency-free uncompressed and unencrypted digital signals over it. They also support HD images. Latency-free service is the reason why these HDI-SDI video converter systems comprising SDI transmitters and receivers are widely employed to meet the complex real-time monitoring requirements in various industries. These systems are part of high-performance surveillance networks in security, army, railways, and so on.
    • HDI-SDI systems can support high image resolutions of 1920 X 1080 resolution. Owing to this, the number of camera devices required to capture the image details are reduced.
    • HDI-SDI video transmitters and receivers aren’t expensive when compared to the advanced technology that it supports.
    • These systems can support transmission for cables that run up to 450 feet or less.

    What Are the Differences Between HD-SDI, and other SDI Standards?

    As the HDI-SDI systems are well-introduced, let’s look at other SDI standards.
    • SD-SDI: The standard supports resolutions up to 576i as well as four different bitrates – 143 Mbit/seconds, 177 Mbit/seconds, 270 Mbit/s, and 360 Mbit/seconds. Of all these, 270 Mbit/s is adopted as the PAL/NTSC standard and its widescreen version can support the bandwidth up to 360 Mbit/s.
    • Dual Link HD-SDI: This is an upgraded standard of HD-SDI and it can support bitrates up to 3 Gbit/seconds and progressive resolution up to 1080p at diverse frame rates such as 50 Hz, 59.94 Hz, and 60 Hz.
    • 3G-SDI: This standard was introduced in 2006 and later revised in 2012. 3G-SDI is a 3 Gbit/s interface and it supports all features of the Dual Link HD-SDI 1.485 Gbit/s interface. In real, it delivers only 2.970 Gbit/s and 2.970/1.001 Gbit/S. If looked at closely, you will find that 3G-SDI and Dual Link HD-SDI work similarly; however, the only difference is you need to use only one cable compared to two used by the earlier. This standard supports different mapping levels which are known as A, B-DL, and B-DS.
    • 6G-SDI: This standard defines all requirements needed for transporting of 5.94 Gb/s and 5.94/1.001 Gb/s. 6G-SDI can support 4K 30 frames in a single link. The standard was introduced in 2015. Earlier 4 X HD-SDI signals or 4X 3G SDI signals were used to transmit 4K X60 frames per second. Now, everything is replaced by a single link 6G-SDI.  
    • 12G-SDI: The standard was introduced in 2015 and was revised in 2018. It assimilates High Dynamic Range (HDR) and Standard Dynamic Range (SDR) source formats into a multiplex or single 12G-SDI 10-bit interface. 12 G-SDI can support 8K 30 from dual links and 4K 60 from a single link.
