An apparatus is configured to perform a method for scrolling a display screen to correspond to a touch input in a mobile terminal. Upon detecting a touch input, the mobile terminal determines an actual coordinate value of the detected touch input, obtains a predicted coordinate value for the determined actual coordinate value, obtains a smoothed coordinate value by performing a smoothing operation on the obtained predicted coordinate value, and determines that the detected touch input has occurred at the obtained smoothed coordinate value.

Method and apparatus for handling touch input in a mobile terminal

A multimedia redirection system and method using an IP PBX are provided. The PBX system allocates at least one channel for multimedia data transmission between a private IP terminal and a public IP terminal, maps between ports of the channels, and direction-transmits the multimedia data between the private IP terminal and the public IP terminal.
