Method and apparatus for filtering a mobile high-definition link signal

摘要

A method and an apparatus perform Mobile High-definition Link (MHL) signal filtering. The method of performing the Mobile High-definition Link (MHL) signal filtering in a terminal includes determining whether a transmission device for MHL signal transmission is connected; determining whether a call continues when the transmission device is connected; and determining whether to perform the MHL signal filtering in the terminal based on whether the call continues. Accordingly, there is an advantage of improving picture quality of an image output from a multimedia device by effectively removing a common mode noise even when an RF weak electric field is formed due to call generation.

1. A method of performing Mobile High-definition Link (MHL) signal filtering in a terminal, the method comprising:
determining whether a transmission device for MHL signal transmission is connected to the terminal; determining whether a call continues when the transmission device is connected; determining whether to perform the MHL signal filtering in the terminal based on whether the call continues; and generating a control signal for instructing the transmission device to perform the MHL signal filtering and transmitting the control signal to the transmission device.
