Abstract
A power-saving method for switching High Definition Multimedia Interface (HDMI) ports on a sink device. The sink device has at least one HDMI port. The sink device is used to receive data frames via a fixed rate link (FRL). The method includes turning off a power of an HDMI port for a power-off period upon detecting an active pixel, and turning on the power of the HDMI port for a power-on period upon completion of the power-off period. The power-on period includes at least a scrambler reset period (TSR) and a high bandwidth digital content protection (HDCP) period.
