Title:
METHOD AND DEVICE FOR ELIMINATING INTERFERENCE AND SMART TELEVISION SET
Document Type and Number:
WIPO Patent Application WO/2017/096766
Kind Code:
A1
Abstract:
A method and device for eliminating interference and a smart television set. The method comprises: determining whether an interference pulse exists in a current inter-integrated circuit (IIC) bus when sensing a read/write data instruction (S10); monitoring in real time a serial data (SDA) bus pulse and a clock pulse of the IIC bus when an interference pulse exists in the current IIC bus (S20); and adjusting the voltage of the clock pulse when the SDA bus pulse and the clock pulse satisfy a predetermined condition (S30). Voltage adjustment for a clock pulse when an interference pulse exists in an IIC bus is implemented, thereby avoiding the problem of data transmission error between an external apparatus and a main chip of a smart television set caused by a change in a start or stop condition of an IIC bus protocol due to a change in an SDA bus pulse and the clock pulse because of the interference pulse; and data transmission of the IIC bus is ensured by correcting the high-low level of the clock pulse.
