1. A data encoding method comprising:
determining a value of a syntax element of point cloud data of a point cloud, the point cloud data including attribute values of the point cloud and the syntax element indicating a search range of the attribute values during prediction encoding;
performing prediction processing on the attribute values according to the search range, to obtain residuals of the attribute values; and
encoding the residuals and a difference between the value of the syntax element and a constant value, to generate code stream data, the constant value being 1.
