Abstract
Activation systems and methods initiate High-Definition Multimedia Interface (HDMI) communication between an HDMI source and an HDMI sink through an HDMI receptacle of the source. These systems and methods are especially suited for use with mobile sources that generally operate from a battery that cannot provide the +5V signal which the HDMI protocol requires sources to place on the +5V pin of their HDMI receptacles. These systems and methods automatically detect the insertion of an HDMI cable into the source's HDMI receptacle and subsequently generate and apply the required +5V signal to the +5V pin of the source's HDMI receptacle to initiate HDMI communication. Because they are directed to use in mobile sources, the embodiments are configured to minimize current drain.
