A handwriting acquisition method, a handwriting transmission method and apparatus, and a graphics tablet and a system therefor. The handwriting transmission method comprises: obtaining a handwriting point after a writing signal is detected, the writing signal being generated by a writing action; determining whether the handwriting point is a handwriting starting point; if yes, encoding the handwriting starting point by using a first encoding rule, comprising encoding initial coordinate information and initial pressure information of the handwriting starting point; and if not, sampling point data is a handwriting intermediate point or a handwriting ending point; encoding the handwriting intermediate point or the handwriting ending point by using a second encoding rule, comprising encoding relative coordinate information and relative pressure information of the handwriting intermediate point or the handwriting ending point. The sampling frequency between adjacent handwriting points at fixed intervals is used fo
