Remote Production for Live Holographic Teleportation Applications in 5G Networks

Abstract

Holographic Teleportation is an emerging media application allowing people or objects to be teleported in a realtime and immersive fashion into the virtual space of the audience side. Compared to the traditional video content, the network requirements for supporting such applications will be much more challenging. In this paper, we present a 5G edge computing framework for enabling remote production functions for live holographic Teleportation applications. The key idea is to offload complex holographic content production functions from end user premises to the 5G mobile edge in order to substantially reduce the cost of running such applications on the user side. We comprehensively evaluated how specific network-oriented and application-oriented factors may affect the performances of remote production operations based on 5G systems. Specifically, we tested the application performance from the following four dimensions: (1) different data rate requirements with multiple content resolution levels, (2) different transport-layer mechanisms over 5G uplink radio, (3) different indoor/outdoor location environments with imperfect 5G connections and (4) different object capturing scenarios including the number of teleported objects and the number of sensor cameras required. Based on these evaluations we derive useful guidelines and policies for future remote production operation for holographic Teleportation through 5G systems.

Toward immersive communications in 6G

“…Thanks to network function virtualization (NFV), functions such as data fusion, data compression, and data rendering can be virtualized and flexibly deployed at MEC servers. In this case, captured data from different sources can be aggregated, fused, and synchronized at an MEC server before rendering (Qian et al, 2022). Moreover, a multi-tier computing scheme is proposed for 6G networks, which can be utilized for holographic communication by integrating computing resources at cloud servers, MEC servers, and local devices, to achieve a low delay for data transmission and high computing capacity for data processing with collaboration among different servers (Yang et al, 2018;Wang K. et al, 2022).…”

“…Motivated by the potentials of immersive communications, scientists and engineers over the world have been working on the development of related technologies, products, and platforms. Significant progress has been made in recent years, including but not limited to advancements in sensor systems and data capture techniques (Dahiya et al, 2019;Meyer et al, 2022), data processing and computing frameworks (Petkov et al, 2022;Qian et al, 2022;Song et al, 2022), and rendering and display devices (Hirayama et al, 2019;Schmitz et al, 2020;Xiong et al, 2021). Some component development of immersive communications is progressing faster than others, leading to the establishment of testbeds, prototypes, or even commercial products.…”

The Development and Implementation for Encryption of Quantum Communication

“…However, the problem is still the speed of electromagnetic wave. Even though concept like 5G has improved the network efficiency as much as possible, there is still time can't be squeezed, and if the distance between two terminals gets far enough, the delay will bring about more inconvenience with the time added from milliseconds to minutes [4,5]. Contempoaraily, Quantum communication is a feasible path.…”
