A clock control method for a High Definition Multimedia Interface (HDMI) receiver operating in a power-saving mode in a sink device is provided. The HDMI receiver has a first module, a second module, and a third module. The clock control method includes the following stages. A clock signal is enabled to be sent to the first module and the third module during a first region of received data. The clock signal is disabled to be sent to the second module during the first region of the received data. The clock signal is enabled to be sent to the third module and the clock signal is disabled to be sent to the first module and the second module during a second region of the received data.

Clock control method and electronic device thereof

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.

Channel hiatus correction method and HDMI device

A power-saving method for an HDMI device is provided. The method includes detecting color depth information of video data from an HDMI source which is connected to the HDMI port, deriving a horizontal length for each line by fragment of a picture frame according to the color depth information, generating a plurality of synchronization signals according to the horizontal length for each line by fragment, and powering on the HDMI port, according to the synchronization signals, for a predetermined time period to obtain encrypted information from the HDMI source, and powering off the HDMI port after the predetermined time period.
