The establishment of the OpenGMSL Association, which brings together industry leaders, is an important step in accelerating the evolution of automobiles through the standardization of high-speed video transmission that underpins autonomous driving and infotainment.
🟦 Industry Standardization Association Launched for a New Era of In-Vehicle Video Transmission
Major players in the automotive industry, led by Analog Devices (ADI), have announced the formation of the OpenGMSL Association. The goal is to create an open standard for SerDes standards (serializers/deserializers) for high-speed video and data transmission required for automotive cameras, displays, and other applications.
OpenGMSL is based on ADI’s Gigabit Multimedia Serial Link (GMSL) technology, and plans are made to require certification testing and multi-vendor compatibility in the future. More than 22 companies, including Denso, Qualcomm, Hyundai Mobis, and GlobalFoundries, are participating in the association, which aims to ensure interoperability across the entire automotive ecosystem.
🟦 Intensifying Competition in Video Transmission and the Significance of OpenGMSL
As automobiles become more sophisticated, technology that transmits high-resolution camera images in real time without delay is indispensable for ADAS (Advanced Driver Assistance Systems) and autonomous driving. Until now, TI’s FPD-Link and ASA’s ASAR (Automotive SerDes Alliance Reference) existed, but both tended to be proprietary or region-dependent, and interoperability was a problem.
GMSL has already shipped more than 1 billion units and has been adopted by European OEMs such as BMW and Mercedes-Benz, and is highly regarded in terms of reliability.
🟦 Summary
The establishment of the OpenGMSL Association is an important step toward the standardization of video and data transmission standards, which are essential for the evolution of automotive technologies such as autonomous driving, infotainment, and ADAS. Multi-vendor support is expected to reduce costs and speed up development.
SerDes (serializer/deserializer) technology is an important element that supports the foundation of communications, but it is a field where standardization is difficult to progress because proprietary specifications tend to be scattered for each application.
