Holographic video communications epitomize a paradigm shift within the domain of visual communications. Arising from the amalgamation of advancements in optics, computational algorithms, and display technologies, holography transcends the confines of conventional communication modalities. The capacity to construct three-dimensional, lifelike depictions of information heralds unprecedented frontiers in telepresence, data visualization, and user interaction. In recent years, concerted efforts within relevant domains have driven remarkable advancements in holographic displays, imaging, and telepresence, establishing holography as a transformative technology across diverse sectors. From healthcare and education to entertainment and collaborative workspaces, holographic video communications fundamentally reshape our perceptual and interactive engagement with information, meriting acknowledgment as a significant component of the 6G Vision outlined in International Mobile Telecommunications (IMT) towards 2030.
