HDMI收税20年，移动“超高清时代”能否有中国标准？

Core Viewpoint - The emergence of the GPMI (General-Purpose Multimedia Interface) standard represents a significant shift in the audio-visual interface landscape, aiming to unify various standards and reduce the complexity of connections in electronic devices, while leveraging China's manufacturing and technological capabilities [1][6][27]. Group 1: Industry Context - The HDMI standard, established in 2002 by major Japanese companies, has dominated the market but has imposed a "technology tax" on manufacturers, particularly in China, where the burden is estimated at around 60% of the total fees collected globally [1][4][19]. - In 2024, Chinese manufacturers such as TCL, Hisense, and Xiaomi are projected to hold a combined 31.3% share of the global television market [1][19]. - The GPMI standard is being developed in response to the limitations of existing interfaces like HDMI and DisplayPort, which have struggled to adapt to the evolving needs of high-definition content and smart devices [6][27]. Group 2: GPMI Features and Advantages - GPMI supports high bandwidth of 96Gbps for 8K 120Hz uncompressed video transmission and can provide up to 480W of power, making it suitable for a wide range of devices [9][10][12]. - The GPMI Type-C interface is designed to be backward compatible with existing USB Type-C, ensuring a smooth transition for consumers and manufacturers [15][18]. - GPMI's dual-directional transmission and control capabilities allow for a single remote to manage multiple connected devices, enhancing user convenience [10][12]. Group 3: Industry Support and Development - The GPMI initiative has garnered support from over 90 industry partners, including major manufacturers and research institutions, indicating a strong collaborative effort to establish this new standard [16][18]. - The Chinese government has shown commitment to GPMI's development through various supportive policies aimed at accelerating its adoption in the audio-visual industry [19][20]. - The GPMI standard is expected to play a crucial role in the rapidly growing ultra-high-definition market in China, projected to reach a scale of 5 trillion RMB by 2024 [20][27]. Group 4: Challenges and Market Dynamics - Despite the strong technical advantages of GPMI, there are concerns regarding its market adoption, as many manufacturers are still unaware of the technology, and existing consumer habits may pose resistance to change [21][24]. - The presence of a vast number of legacy devices in the market complicates the transition to GPMI, as compatibility with older technologies remains a significant hurdle [24][25]. - The success of GPMI will depend on its ability to deliver tangible benefits to consumers and effectively compete with established standards like HDMI and DisplayPort [21][26].
