Abstract
Systems and methods for charging a mobile device using a high-speed data interface are described. Power may be provided from Transition Minimized Differential Signaling (TMDS) lines when TMDS data is transmitted via a High-Definition Multimedia Interface (HDMI) connection between a transmitter, such as a mobile device, and a receiving device. Power may be provided to the mobile device in exemplary embodiments such that when the transmitter is in idle or power down state, power may be provided from TMDS lines as part of an upstream charging function.
