Outline
Ultra–high–definition (UHD) video is one of the key development directions for China's audiovisual industry. In response, relevant national departments have introduced a series of policies to encourage and support the development of the UHD video industry. The processes of capturing, transmitting, producing, and broadcasting UHD video, especially when integrated with advanced AI content generation technologies such as ChatGPT and Sora, exhibit typical characteristics of high bandwidth, high computing power, and low latency. These characteristics pose significant challenges to computing power and network infrastructure. Based on the typical requirements of UHD video and the latest trends in computing and network technologies, this paper proposes a computing power network architecture tailored for UHD video. It comprehensively employs key computing power network technologies such as heterogeneous computing resource networking and secure transmission technologies, UHD video service demand modeling and resource orchestration technologies, joint scheduling and routing planning technologies combining "data, computing, and modeling," and high–speed transmission technologies for UHD video. This approach aims to achieve the aggregation and networking of heterogeneous computing power across the country, thereby meeting the diverse computing and network transmission needs of various stages of UHD video processing, including capture, editing, and broadcasting.
