Abstract: A channel hiatus correction method for an HDMI device is provided. A recovery code from scrambled data of the stream is obtained. A liner feedback shift register (LFSR) value of channels of the HDMI port is obtained based on the recovery code and the scrambled data of the stream. The stream is de-scrambled according to the LFSR value of the channels of the HDMI port. Video data is displayed according to the de-scrambled stream.
