摘要： A method of confirming a receipt of protocol data units (PDU) that can eliminate the starting point polling problem of the conventional window-based polling algorithm widely used in a radio link control is disclosed. The conventional window-based polling algorithm is modified in such a way that the unwanted polling is eliminated when transmitting the protocol data units at the starting point of the communication window.

摘要： Disclosed are methods and systems of watermarking multimedia data using mobile communication terminals. More particularly, methods and systems of selectively watermarking the multimedia data are disclosed. According to the present invention, it is made possible to trace and check author or provider of multimedia data without intervention of a certificate authority, thereby protecting copyright of multimedia data and resolving problems misusing and abusing multimedia data relating to other person's privacy. Further, it is made possible to minimize economic loss and to prevent processing speed of mobile communication terminals from being reduced.
