Core Viewpoint - The Shenzhen 8K Ultra HD Video Industry Cooperation Alliance (SUCA) announced the upcoming official release of the General Multimedia Interface (GPMI) series electronic industry standards, marking a significant breakthrough in key technology standards in the high-speed multimedia interface field in China [1][4]. Group 1: Industry Standards - The GPMI standard comprehensively covers critical aspects such as interface physical layer, protocol layer, power supply, security, and interoperability, providing unified specifications for the design, research, and testing of products in the chip, terminal, and instrumentation sectors [3][4]. - The GPMI is a domestically developed high-speed digital interface that surpasses existing standards like USB Type-C and HDMI in transmission speed, signal capability, and resolution [3][4]. Group 2: Technical Innovations - The GPMI's key innovation is its ability to integrate signal transmission, power supply, and audio-video functions through a single cable while maintaining full compatibility with Type-C interfaces [3][4]. - Technical specifications indicate that GPMI supports a maximum bandwidth of 192 Gbps, a power supply capability of 480W, and 8K video transmission at 120 frames per second, catering to traditional media signal transmission needs as well as advanced applications in smart homes, virtual reality, and cloud computing [3][4]. Group 3: Strategic Development - Under the guidance of regulatory authorities, the China Electronics Standardization Institute has formed a GPMI working group in collaboration with over 90 core industry enterprises, including Huawei, Skyworth, and Hisense, to advance the standard system construction [5]. - The overall strategy involves a phased approach of "group standards leading the way, industry/national standards advancing in parallel, and early layout of international standards," aiming to facilitate China's strategic shift from following to leading in the multimedia interface field [5].
