Abstract
Systems, methods, and media for providing power to an HDMI source are provided. In accordance with some implementations, methods for providing power to an HDMI source are provided, the methods comprising: providing an AC signal to an HPD line of an HDMI port; determining that an L-C circuit is present on the HPD line when applying the AC signal; and in response to determining that an L-C circuit is present on the HPD line, connecting a power source to an HDMI 5V line of the HDMI port. In some implementations, the AC signal is a 231 kHz waveform. In some implementations, the AC signal is generated using a clock output. In some implementations, the methods further comprise integrating the clock output to provide the AC signal. In some implementations, the methods further comprise switching the frequency of the AC signal.
