Abstract
Embodiments of the disclosure provide resolution-based decoding and encoding methods and a bitstream. The method includes the following. A bitstream is parsed to obtain a current patch. Whether the current patch is a patch whose resolution is to be changed is determined. When the current patch is a patch whose resolution is to be changed, the bitstream is parsed to obtain a scaling-rate parameter of the current patch. A scaling factor for the current patch is determined based on the scaling-rate parameter of the current patch. Coordinates of the current patch in a three-dimension (3D) space coordinate system are obtained based on the scaling factor for the current patch.
