Core Viewpoint - The release of Huawei Mate TV has sparked speculation about the interface protocol it uses, with GPMI (General-Purpose Multimedia Interface) being a prominent candidate for adoption, marking a significant step in China's multimedia interface standardization efforts [1][13]. Group 1: GPMI Development and Background - GPMI is not the first attempt at establishing a Chinese multimedia interface standard; previous efforts include DiiVA, which was launched in 2008 but failed to gain traction due to a lack of market influence [2][3]. - The GPMI standard was officially released in 2023, following a series of developmental milestones, including the establishment of a working group in 2019 and the release of a draft standard in 2021 [6][12]. Group 2: Technical and Policy Support - GPMI aims to address the limitations of traditional multimedia interfaces by enabling multi-stream transmission of audio, video, and control signals, enhancing user experience [4][7]. - The Chinese government has provided substantial support for GPMI, designating it as a core technology for high-speed interfaces and facilitating its application in various scenarios [5][10]. Group 3: Competitive Landscape - GPMI faces competition from established international standards like HDMI and DisplayPort, with GPMI Type-C supporting data rates of up to 96Gbps and power delivery of 240W, while Type-B can achieve 192Gbps and 480W [8][9]. - The performance of GPMI has been highlighted as superior to HDMI and DisplayPort, with a broader range of applications, including TVs and data transmission [14][15]. Group 4: Industry Collaboration and Ecosystem Building - Over 50 leading companies, including Huawei and TCL, are collaborating to develop GPMI, creating a comprehensive ecosystem that spans chips, terminals, and testing [10][11]. - The first GPMI-enabled smart TV was launched by Haier in late 2024, marking a significant entry into the consumer market and enhancing GPMI's visibility [12]. Group 5: Strategic Importance - The establishment of GPMI is seen as a crucial step for China to gain a foothold in the global multimedia interface market, potentially breaking the long-standing dominance of international standards [13][14]. - GPMI's development is positioned as a strategic move to enhance China's technological sovereignty and competitiveness in the global tech landscape [15].
