Method and system for ink data generation, ink data rendering, ink data manipulation and ink data communication

A method implemented by a transmission device to communicate, via a server, with multiple reception devices that respectively share a drawing area with the transmission device, the method comprising:

• (a) an ink data generation step that comprises continuously inputting pen even data generated according to movement of a pointer, and generating fragmented data of a stroke object, wherein the stroke object contains multiple point objects to represent a trace of said movement of the pointer, the fragmented data being generated per defined unit T;
• (b) a negotiation step of negotiating with the server to determine a communications parameter value;
• (c) a message formation step that comprises generating a first message and one or more second messages subsequent to the first message, the one or more second messages including the fragmented data;
• and
• (d) a transmission step of transmitting the first message and the one or more second messages in sequence using a communication packet defined by a communications protocol specified by said communications parameter value.
