SD-SDI (Standard SDI), HD-SDI (High Definition SDI), 3G-SDI (3G SDI), 6G-SDI, and 12G-SDI are all different versions of SDI (Serial Digital Interface) standard based on different video transmission application scenarios. The following are the main differences between them:

1. **Resolution**: SD-SDI (Standard SDI) has a resolution of 720p (standard definition). HD-SDI (High Definition SDI) has a resolution of 1080p (full HD). With technological advancements, 3G-SDI (3G SDI) can achieve a resolution of 4K ultra HD, while 6G-SDI and 12G-SDI may have even higher resolutions.

2. **Transmission Speed**: The transmission speed of SDI varies depending on the version. SD-SDI and HD-SDI are typically used for lower speed streaming applications, while 3G-SDI can handle higher speeds. With higher resolutions, 6G-SDI and 12G-SDI may require even higher speeds.

3. **Distance and Stability**: With increasing versions, the transmission distance also increases and becomes more stable. For example, the transmission distance of SD-SDI is typically around 50 feet, while HD-SDI may be around 100 feet, and higher versions such as 3G-SDI, 6G-SDI, and 12G-SDI may have longer transmission distances.

4. **Application Scenarios**: Different versions of SDI are suitable for different application scenarios. For example, SD-SDI and HD-SDI are typically used in broadcast television, while 3G-SDI may be used for more professional live broadcast or recording applications. Higher versions such as 6G-SDI and 12G-SDI may be used in applications that require higher resolutions and speeds, such as healthcare, security monitoring, or robotic vision, among others.
