The advent of the Metaverse concept has further expedited the evolution of haptic, tactile internet, and multimedia applications with their VR/AR/XR services, and therefore, fully-immersive sensing is most likely to define the next generation of wireless networks as a key to realize the speculative vision of the Metaverse. In this magazine, we articulate different types of media that we envision will be communicated between the cyber and physical twins in the Metaverse. In particular, we explore the advantages grasped by exploiting each kind, and we point out critical challenges pertinent to 3D data processing, coding, transporting, and rendering. We further shed light on the role of future wireless networks in delivering the anticipated quality of immersion through the reliable streaming of multimedia signals between the digital twin and its physical counterpart. Specifically, we explore emergent communication paradigms, including semantic, holographic, and goal-oriented communication, which we expect to realize energy and spectrally efficient Metaverse while ensuring ultra-low latency.

沉浸式媒体和大规模结对：迈向虚拟宇宙


元宇宙概念的出现进一步加速了触觉、触觉互联网和多媒体应用及其VR/AR/XR服务的发展，因此，全沉浸式传感最有可能定义下一代无线网络的关键实现元宇宙的思辨愿景。在这本杂志中，我们阐述了我们设想将在元宇宙中的网络和物理双胞胎之间进行交流的不同类型的媒体。特别是，我们探讨了利用每种类型所掌握的优势，并指出了与 3D 数据处理、编码、传输和渲染相关的关键挑战。我们进一步阐明了未来无线网络在通过数字孪生与其物理对应物之间可靠的多媒体信号流提供预期的沉浸质量方面的作用。具体来说，我们探索新兴的通信范式，包括语义、全息和面向目标的通信，我们期望在确保超低延迟的同时实现能源和频谱效率高的元宇宙。
