Publication number: 20240022765Abstract: A system comprises an encoder configured to compress and encode data for a three-dimensional mesh. To compress the three-dimensional mesh, the encoder determines a compressed base mesh bit stream and a compressed motion bitstream. A network abstraction layer syntax defined for the compressed base mesh bit stream and the compressed motion bitstream, allows for various parameters to be defined and applied to both bit streams, such as timing information and faceIDs for faces of polygons of the mesh.Type: ApplicationFiled: July 14, 2023Publication date: January 18, 2024Applicant: Apple Inc.Inventors: Alexandros Tourapis, Dimitri Podborski, Jungsun Kim, Khaled Mammou

Publication number: 20230401755Abstract: A system comprises an encoder configured to compress and encode data for a three-dimensional mesh. To compress the three-dimensional mesh, the encoder determines sub-meshes and for each sub-mesh: texture patches and geometry patches. Also, the sub-meshes may be grouped into patches, patch-groups, and/or tiles. Different encoding parameters may be used for such different coding units (e.g., patches, patch-groups and/or tiles). However, the encoding parameters are adjusted for vertices that are shared between coding units to avoid introduction of artefacts. A decoder receives a bit stream as generated by the encoder and reconstructs the three-dimensional mesh.Type: ApplicationFiled: April 19, 2023Publication date: December 14, 2023Applicant: Apple Inc.Inventors: Khaled Mammou, Alexandros Tourapis, Jungsun Kim, Dimitri Podborski

Publication number: 20230290011Abstract: A video dynamic mesh coding (v-DMC) decoding system, includes a de-multiplexer that receives and demultiplexes an encoded v-DMC bitstream into: a parameter set and mesh data, geometry, atlas data, and attribute video substreams. The decoding system also includes: a mesh data substream decoder; a video decoder that decodes the geometry data substream; an atlas data substream decoder; a mesh subdivision component that subdivides the one or more base meshes into one or more resampled base meshes based upon the decoded atlas data; a displacement decoder that outputs one or more displacements to verticies of the one or more resampled base meshes; a mesh position refinement component that applies the one or more displacements to the one or more resampled base meshes and outputs one or more resultant meshes; and a video decoder that decodes the attribute video substream into one or more texture images.Type: ApplicationFiled: February 8, 2023Publication date: September 14, 2023Inventors: Jungsun Kim, Alexandros Tourapis, Dimitri Podborski, Khaled Mammou, David Flynn

Publication number: 20230089495Abstract: File format concepts for video coding are described. Embodiments allow for an efficient extraction of sub-streams from a video file. Further embodiments allow for a flexible switching between sub-streams of a video file. Further embodiments allow for a flexible handling of decoder initializations.Type: ApplicationFiled: September 30, 2022Publication date: March 23, 2023Inventors: Yago SÁNCHEZ DE LA FUENTE, Dimitri PODBORSKI, Karsten GRUENEBERG, Cornelius HELLGE, Thomas SCHIERL, Robert SKUPIN, Thomas WIEGAND

Publication number: 20230093377Abstract: Various concepts for media content streaming are described. Some allow for streaming spatial scene content in a spatially unequal manner so that the visible quality for the user is increased, or the processing complexity or used bandwidth at the streaming retrieval site is decreased. Others allow for streaming spatial scene content in a manner enlarging the applicability to further application scenarios.Type: ApplicationFiled: September 27, 2022Publication date: March 23, 2023Inventors: Robert SKUPIN, Cornelius HELLGE, Thomas SCHIERL, Yago SÁNCHEZ DE LA FUENTE, Thomas WIEGAND, Dimitri PODBORSKI

Publication number: 20230015840Abstract: File format concepts for video files are described. It is proposed to that descriptive data of a file indicates whether a parameter set for a track of a file is forwarded when jointly decoding a sub-stream of the track and a further track, and/or that a file includes, for a sub-stream of a video stream signaled in the file, an alternative parameter set to a parameter set for fully decoding the track, the alternative parameter set being for decoding the sub-stream, so as to allow for switching between multiple tracks of a file, and/or that step-wise stream access pictures of a track of a file are marked as stream access point pictures for accessing the track, and/or that a temporal length within which a decoder refresh in case of a joint decoding of sub-streams distributed over multiple tracks is indicated in a file, and/or that a file provides information from which it is derivable whether a pixel aspect ratio varies.Type: ApplicationFiled: September 29, 2022Publication date: January 19, 2023Inventors: Yago SÁNCHEZ DE LA FUENTE, Dimitri PODBORSKI, Karsten GRUENEBERG, Cornelius HELLGE, Thomas SCHIERL, Robert SKUPIN, Thomas WIEGAND

Publication number: 20230008125Abstract: The A method of augmenting a view of a real-world environment with a view of a volumetric video object on a user device is disclosed . The method includes determining a current pose information (CPI) indicating a current pose of the view of the real-world environment and a desired pose of the volumetric video object in the real-world environment. The method further includes sending the CPI to a remote server. The method further includes receiving a rendered view of the volumetric video object that has been rendered in accordance with the CPI from the remote server. The method also includes augmenting the view of the real-world environment by at least mapping the rendered view of the volumetric video object onto a planar mapping surface arranged according to the desired position of the volumetric video object.Type: ApplicationFiled: December 15, 2020Publication date: January 12, 2023Applicant: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Cornelius Hellge, Thomas Schierl, Peter Eisert, Anna Hilsmann, Robert Skupin, Yago Sanchez, Jangwoo Son, Gurdeep Singh Bhullar, Serhan Gül, Dimitri Podborski
