Abstrakt v dalším jazyce:	The paper deals with efficient compression of immersive video representations for the synthesis of video relatedto virtual viewports, i.e., to selected virtual viewer positions and selected virtual directions of watching. Thegoal is to obtain possibly high quality of virtual video obtained from compressed representations of immersivevideo acquired from multiple omnidirectional and planar (perspective) cameras, or from computer animation. Inthe paper, we describe a solution based on HEVC (High Efficiency Video Coding) compression and the recentlyproposed MPEG Test Model for Immersive Video. The idea is to use standard-compliant Screen Content Codingtools that were proposed for other applications and have never been used for immersive video compression. Theexperimental results with standard test video sequences are reported for the normalized experimental conditionsdefined by MPEG. In the paper, it is demonstrated that the proposed solution yields up to 20% of bitrate reductionfor the constant quality of virtual video.
