Core Viewpoint - The article discusses the significance of the General-Purpose Multimedia Interface (GPMI) technology, which aims to revolutionize interface technology to meet the demands of future smart applications, particularly in the context of smart homes and industrial IoT [2][24]. Summary by Sections Evolution of Information Storage and Transmission - The progress of civilization is closely linked to the evolution of information storage media and transmission methods, with a notable acceleration in storage technology compared to the slower updates in transmission methods, particularly in interface technology [2]. Introduction to GPMI - GPMI is a restructured interface paradigm designed for smart scenarios, addressing the compatibility issues of existing interfaces in new application contexts. It represents a significant advancement from previous generations of interfaces [3]. GPMI Technical Architecture - The GPMI technology architecture consists of four layers: link layer, tunnel base, adaptation layer, and service layer, with essential components including main and auxiliary links [5]. Core Advantages of GPMI - GPMI boasts seven core advantages: bidirectional multi-stream, bidirectional control, high power supply, ecological compatibility, ultra-fast transmission, quick wake-up, and full-chain security [7]. Bidirectional Multi-Stream Capability - GPMI supports mixed bidirectional transmission of video and data streams, allowing for efficient interconnectivity among multiple devices, with a bandwidth capacity of 192 Gbps and support for up to 128 nodes [10][12]. Bidirectional Control Functionality - The bidirectional control feature enables dynamic reconfiguration of roles between interconnected devices, allowing for enhanced functionality and resource sharing, such as using a TV's network capabilities for other devices [15]. High Power Supply Integration - GPMI integrates power supply capabilities, with Type-B interfaces supporting up to 480W and Type-C interfaces up to 240W, facilitating a unified connection for video, control, data, and power [18]. Ecological Integration - GPMI is compatible with USB standards, ensuring seamless integration with existing devices and laying the groundwork for future standards, which is beneficial for both manufacturers and consumers [21]. Future Opportunities with GPMI - GPMI is expected to unlock new development opportunities in smart scenarios, enhancing multi-screen ecosystems in smart homes and industrial IoT applications, while also fostering new business models such as "display as a service" [24].
