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.

Abstract: A method for measuring a muscle tone is used in a muscle tone measuring system including a sensing end and a processing end. The method for measuring the muscle tone includes respectively arranging the sensing end and the processing end on first and second limb parts of a limb that are interconnected by a joint of the limb. The sensing end detects a strength of a force that is applied to the first limb part and a plurality of physical quantities of a movement of the first limb part. The processing end detects an environment temperature and the physical quantities of a movement of the second limb part, and collects the physical quantities of the movements of the first and second limb parts, the environment temperature and the strength of the force according to a sampling rate during a period of measuring time. The muscle tone measuring system is also provided.
