Abstract

Method and apparatus for encoding, decoding and rendering 3D media content are provided. An apparatus for rendering three-dimensional (3D) media content includes a communication interface configured to receive a multimedia stream, and one or more processors operably coupled to the communication interface, the one or more processors configured to parse the multimedia stream into 2D video bitstreamsincluding geometry frames and texture frames, 2D to 3D conversion metadata for rendering 3D points from 2D frames, and scene description metadata describing 6 degree of freedom (6DoF) relationships among objects in a 6DoF scene, decode the 2D video streams including geometry data and texture data to generate 2D pixel data, covert the 2D pixel data into 3D voxel data using the 2D to 3D conversionmetadata; and generate the 6DoF scene from 3D voxel data using the scene description metadata.

Description

technical field [0001] The present disclosure generally relates to methods and apparatus for rendering three-dimensional (3D) content. More specifically, the present disclosure relates to methods and apparatus for encoding, decoding or rendering immersive 3D media. Background technique [0002] Three hundred sixty degree (360°) video is becoming a new way to experience immersive video thanks to the instant availability of powerful handheld devices such as smartphones. 360° video provides consumers with an immersive "real life" and "immersive" experience by capturing a 360° panorama of the world. Users can interactively change their point of view and dynamically view any part of the captured scene or object according to their needs. Display and navigation sensors track head movement in real time to determine the area of ​​the 360° video the user wants to view. 360° video provides three degrees of freedom (3DoF) immersive experiences. (6DoF) is the next stage of immersive ...
