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].

Group 1 - The GPMI industry ecosystem promotion conference and standardization seminar was held to advance the industrialization of GPMI technology and standardize complex television operations [1][2] - Over a hundred experts and scholars from various sectors, including the Ministry of Industry and Information Technology and major telecommunications companies, participated in the discussions [1] - The establishment of the GPMI industry expansion group, consisting of over 20 organizations, marks a significant step in building the GPMI industry ecosystem [2] Group 2 - The conference included the drafting group meeting for the television operation complexity governance standards, discussing existing and upcoming industry standards [3] - A GPMI exhibition area showcased the latest achievements in set-top boxes, televisions, chips, and testing equipment [3] - The GPMI ecosystem aims to enhance collaboration, accelerate technology dissemination, and create a smarter and more convenient audiovisual experience for consumers [3]

Core Viewpoint - The article discusses the advancements in HDMI technology, particularly focusing on HDMI 2.1 and the newly announced HDMI 2.2, highlighting their features and implications for consumers and the industry [1][5]. Group 1: HDMI 2.1 Overview - HDMI 2.1 was officially announced in November 2017, significantly increasing bandwidth from 18 Gbps to 48 Gbps, allowing for higher video resolutions and refresh rates [3]. - It supports 120 Hz 4K video, 60 Hz 8K video, and even 10K video, along with advanced gaming features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) [3][4]. - HDMI 2.1b also includes features like HDMI eARC for lossless audio transmission and dynamic HDR support for scene-by-scene optimization [4]. Group 2: HDMI 2.2 Features - HDMI 2.2, announced at CES 2025, doubles the bandwidth to 96 Gbps, targeting commercial applications and advanced consumer technologies like AR and VR [5][6]. - It aims to enhance medical imaging and next-generation media production, with potential applications in machine vision for robotics and autonomous vehicles [6][7]. - A notable improvement is the Low Latency Indication Protocol (LIP) for better audio-video synchronization between devices [7]. Group 3: GPMI Development - The GPMI (General Purpose Media Interface) was developed by a coalition of over 50 Chinese companies, providing a unified multimedia interface solution [9][10]. - GPMI offers a bandwidth of up to 192 Gbps and a power delivery capability of 480W, addressing the complexity of multiple connections in traditional setups [10]. - It supports dual-directional control, allowing users to operate multiple devices through a single interface, enhancing user experience [10][11]. Group 4: Comparison with Existing Technologies - GPMI is positioned as a potential alternative to HDMI and DisplayPort, with specifications that surpass current standards in terms of bandwidth and power delivery [10][11]. - HDMI 2.1 and DisplayPort 2.1 have lower bandwidth capabilities compared to GPMI, which could lead to a shift in industry standards [10].
