UWA Standards WG: Consensus Forging an Ultra HD Future

2025-04-16

Introduction to the Series Report：

Working Groups (WG) are the engine driving the development and implementation of international standards, pooling the expertise of global specialists and using consensus to drive technical specifications and industry practices in specific fields. Within the Hetao International Organization Headquarters, dozens of working groups exhibit a vibrant landscape of high specialization and domain diversity. To overcome the inherent challenges of cross-regional and cross-time-zone collaboration, the digital collaboration platform AllianceHub plays a crucial role. Through integrated online tools, it streamlines communication and decision-making processes, enabling global experts to concentrate on core deliberations, improving the quality and value density of outcomes, effectively underpinning the efficient operation of the Hetao working group ecosystem, and establishing global innovation influence.

UWA Standards Working Group

Consensus Forging an Ultra HD Future

The birth of international standards often depends on a core unit—the working group. These groups serve as crucibles, bringing together the expertise of global specialists through detailed discussions and negotiations, ultimately forging technical specifications and practice guidelines that drive industry progress through consensus. Within the UHD World Association (UWA), an international body committed to advancing the global ultra-high-definition (UHD) industry, the Standards Working Group plays this pivotal role. Its main task is to establish clear and consistent technical standards for the fast-evolving UHD video sector. These standards aim not only to regulate technical specifics and ensure quality from content creation to end-user presentation but also to lay a sturdy technical foundation for the healthy, orderly, and innovative growth of the global UHD video industry.

The significant accomplishments of the UWA Standards Working Group are closely linked to its diverse and balanced membership. Headed by the authoritative China Electronics Standardization Institute (CESI), the working group includes many of China's leading research institutions and standardization bodies, such as the Academy of Broadcasting Planning and the China Academy of Information and Communications Technology (CAICT). These prominent think tanks provide deep theoretical grounding, forward-thinking technological perspectives, and extensive standard-setting experience, forming the intellectual and professional bedrock of standard development.

Simultaneously, the member list of the working group nearly outlines a full picture of the UHD video industry. From tech and platform leaders like Huawei, Tencent, and Alibaba, to hardware manufacturing giants in TVs, display panels, and chips such as Hisense, TCL, BOE, Sony, and Samsung, to content production and broadcasting powerhouses like China Media Group, China Mobile Migu Company, Tencent, iQIYI, Youku, and network transmission backbones like China Telecom, China Unicom, and China Mobile—nearly every key link from technology R&D, equipment manufacturing, content production, network distribution, to end-user presentation is covered. This widespread participation across the entire industry chain ensures that standard setting fully considers all stakeholders' needs and closely aligns with industrial realities.

Moreover, the working group includes several authoritative third-party testing and certification institutions, such as the China CESI Laboratory, CTTL, NRTA Audio-Video Testing Laboratory, National Testing and Inspection Center for Radio and TV Products (Beijing TIRT), and CEPREI. Their involvement provides critical support for the effective implementation and quality verification of standards, forming a closed loop of "development-implementation-verification." Notably, the inclusion of internationally renowned companies like Sharp, Sony, Samsung, and LG Display not only brings valuable international market experience and perspectives but also underscores the openness and international scope of UWA’s standard work. It can be said that the UWA Standards Working Group unites forces from "government, industry, academia, research, application, and testing," and this multifaceted collaborative structure enables it to efficiently produce high-quality standards, serving as a solid foundation driving industrial development.

Since its inception, the UWA Standards Working Group has demonstrated efficient operations and robust output capabilities, releasing dozens of important alliance standards in just a few years. These ‘T/UWA’ standard documents create a comprehensive set of technical specifications for the UHD video field. Their content spans widely, delving into core audio-visual experience aspects such as High Dynamic Range (HDR) video technology (e.g., T/UWA 005 series) and 3D audio technology (e.g., T/UWA 009 series), and sets clear technical requirements and testing methods for key products and systems such as 4K/8K content exchange parameters (T/UWA 008), intelligent video processing (T/UWA 010), UHD LED displays (T/UWA 011), and UHD electronic whiteboards (T/UWA 013).

Particularly noteworthy is that the working group provided comprehensive standardization support for the national key project “Hundred Cities, Thousand Screens” initiative, formulating a complete set of specifications from program broadcasting, audio-video encoding, network transmission to public display systems (T/UWA 012 series), strongly ensuring the smooth implementation and effect presentation of the project. Additionally, the working group stays abreast of cutting-edge technologies and has released technical standards in emerging fields such as XR virtual-real fusion production (T/UWA 016), 3D digital humans (T/UWA 019), and high dynamic range still images (T/UWA 028.1).

The frequent release of these standard results has provided the industry with clear technical guidance and quality benchmarks, significantly promoting technological innovation, product interoperability, and the popularization of UHD video applications, fully demonstrating the core value of this working group in driving industrial development.

The daily operations of the UWA Standards Working Group are carried out through the digital collaboration platform AllianceHub, including core processes such as submitting topic solicitations, organizing meetings, and conducting consensus voting. Those wishing to communicate with the working group, participate in discussions, or learn more information can interact via the AllianceHub platform. Additionally, you can contact the working group by sending an email to the official contact email contact@theuwa.com.
