全息视频通信被视为视觉通信的范式变革，因其提供沉浸式体验而日益流行。本文综述全息视频通信并明确系统需求，结合语义通信研究，提出一种语义增强型全息视频通信架构。关键技术创新包括语义采样、联合语义-信道编码和语义感知传输。通过两个典型应用场景验证了该方法在性能上的提升。最后讨论潜在研究方向，为实现语义增强的全息视频通信铺路。
原文摘要 · Abstract (English)
Holographic video communication is considered a paradigm shift in visual communications, becoming increasingly popular for its ability to offer immersive experiences. This article provides an overview of holographic video communication and outlines the requirements of a holographic video communication system. Particularly, following a brief review of semantic com- munication, an architecture for a semantic-enabled holographic video communication system is presented. Key technologies, including semantic sampling, joint semantic-channel coding, and semantic-aware transmission, are designed based on the proposed architecture. Two related use cases are presented to demonstrate the performance gain of the proposed methods. Finally, potential research topics are discussed to pave the way for the realization of semantic-enabled holographic video communications.
