论文摘要
随着沉浸式媒体应用的出现，这种内容的表示和消费的要求大大增加了。媒体资产的不断增加的规模与严格的运动潜伏期需求相结合，使难以解决的XR流媒体服务具有高质量的体验。 MPEG-I标准旨在促进沉浸式应用的广泛部署。本文介绍了第13部分，视频解码接口和第14部分，MPEG-I的MPEG媒体的场景描述，分别解决解码器管理和虚拟场景组成。这些新零件旨在使复杂的媒体渲染操作和硬件资源管理隐藏在应用程序中，从而降低XR应用程序的障碍，使其成为主流，XR Experience Developers and Designers可以访问。预计这两个部分将在2021年底由ISO发布。
With the advent of immersive media applications, the requirements for the representation and the consumption of such content has dramatically increased. The ever-increasing size of the media asset combined with the stringent motion-to-photon latency requirement makes the equation of a high quality of experience for XR streaming services difficult to solve. The MPEG-I standards aim at facilitating the wide deployment of immersive applications. This paper describes part 13, Video Decoding Interface, and part 14, Scene Description for MPEG Media of MPEG-I which address decoder management and the virtual scene composition, respectively. These new parts intend to make complex media rendering operations and hardware resources management hidden from the application, hence lowering the barrier for XR application to become mainstream and accessible to XR experience developers and designers. Both parts are expected to be published by ISO at the end of 2021.
