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].
