The scope of this special issue proposal comprises recent advances in media coding/compression techniques, specifically focusing on video, image, and audio for both traditional and immersive media content including but not limited to omnidirectional/360-degree. Additionally, it covers multimedia systems technologies for both omnidirectional/360-degree and immersive media in general including an outline towards fully six Degrees of Freedom (6DoF) adaptive streaming using point cloud compression. The actual point cloud compression techniques for both video- and geometry-based will be addressed also. Finally, this special issue will also cover new domains for compression/coding techniques such as genomic data.
