A communication impact processing method in a device link system based on a TV is provided to prevent an error from being generated in message transmission by communication impact by connecting slave devices of various types to a master device like a digital TV by a daisy chain type by using a stereo jack, generating a request message and a response message transmitted between the master device and the slave devices as a certain format, and transmitting and receiving the request message and the response message. When communication impact between a master device of a device link system based on a TV and a plurality of slave devices is generated, the master device selectively processes only a message of the slave device finally connected. The slave devices except for the slave device in which the message is selectively processed judge the communication impact and a communication state, and resume message transmission. The communication impact occurs while one master device is communicated with N slave devices.
