Audiovisual rendering apparatus and method of operation therefor

Abstract

To provide an audiovisual rendering apparatus, method, and program for improving the user experience in virtual reality applications.SOLUTION: An audiovisual rendering apparatus comprises a receiver (201) receiving audiovisual items and a receiver (209) receives metadata comprising input poses provided with reference to an input coordinate system and rendering category indications. A receiver (213) receives user head movement data and a mapper (211) maps the input poses to rendering poses in a rendering coordinate system in response to the user head movement data. A renderer (203) renders the audiovisual items using the rendering poses. The mapper selects a rendering category for an audiovisual item in response to a rendering category indication and maps an input pose to rendering poses that correspond to fixed poses in a category coordinate system for varying user head movement where the category coordinate system is determined from the coordinate system transform of the rendering category.SELECTED DRAWING: Figure 2
