1. A method of point cloud video decoding, executable by a processor, comprising:
receiving, from a bitstream, data of a video corresponding to a point cloud;
obtaining from the data a first prediction residual of a first component from among a plurality of components of an attribute associated with the point cloud;
reconstructing the first prediction residual;
determining a predicted second prediction residual based on the reconstructed first prediction residual and at least one model parameter;
obtaining a second prediction residual of a second component from among the plurality of components based on the predicted second prediction residual;
reconstructing the second prediction residual based on the predicted second prediction residual; and
decoding the data corresponding to the point cloud based on the reconstructed first prediction residual and the reconstructed second prediction residual, and decoding the data comprises decoding and causing a video of the point cloud, which is represented by the data, to be played, the point cloud representing any of color, reflectance, and positions of one or more objects in the video of the point cloud.
