The State-of-the-art Advancements and Challenges of 3D Video Formats

Abstract

         3D video communication has become one of the most prominent ways of sharing and exchanging rich visual information, driven by the growing demand for immersive media in applications such as virtual reality, augmented reality, telepresence, and advanced broadcasting systems. To achieve this objective, the source coding should compress the original video sequence as much as possible, and the compressed video data should be robust and resilient to channel errors. In this respect, it is necessary to provide both efficient video formats and advanced compression standards capable of balancing bitrate reduction with high visual fidelity while including mechanisms that improve error resilience, granting reliable transmission over bandwidth-limited and error-prone communication channels. The aim of this paper is to provide a comprehensive survey of up-to-date formats, recent developments, and challenges concerning the efficient representation, compression, and delivery of immersive content in 3D formats.
