SYNCHRONIZING METHOD USING VIRTUAL CLOCK METHOD, ESPECIALLY WITHOUT SYNCHRONIZATION BETWEEN TWO SYSTEMS REPEATEDLY

摘要

PURPOSE: A synchronizing method using a virtual clock method is provided to predict system clocks of two systems by sharing a system clock ratio between two systems. CONSTITUTION: A data transmission process is repeatedly performed between two systems. A clock offset is converted by using a half of a mean value of delayed values in a repeating process. A clock ratio between two systems is calculated by using the clock offset. The information about the calculated clock offset and the clock ratio is shared by a source and a destination system. The data is transmitted from the source to the destination system and the destination system converts the data and displays the converted data.
