Abstract: The present invention relates to a method and apparatus for encoding a displacement video using image tiling. A method for encoding multi-dimensional data according to an embodiment of the present disclosure may comprise: converting the multi-dimensional data into one or more frames with two-dimensional characteristics; generating one or more frame groups by grouping the one or more frames with pre-configured number units; reconstructing frames belonging to each frame group into a tiled frame; and generating a bitstream by encoding the tiled frame. Here, the tiled frame may be constructed with one or more blocks, and each block may be constructed by rearranging pixels existing at the same location in the frames.

Abstract: A method and a device for transmitting and obtaining dynamic 3-dimensional (3D) avatar data are provided. The method for transmitting dynamic 3D avatar data may include generating a plurality of data elements configuring the dynamic 3D avatar data; performing first encoding and transmission for a first data element of the plurality of data elements; and performing second encoding and transmission for a second data element of the plurality of data elements. Each of at least one of the first data element or the second data element may be divided into a plurality of sub-data elements.

Abstract: A method of encoding a dynamic mesh includes creating a base mesh through mesh decimation, subdividing the base mesh, extracting displacement information for the subdivided mesh, and encoding the base mesh and the displacement information. In this instance, mesh subdivision information for subdivision of the base mesh is encoded and signaled.
