Abstract: Methods, systems, circuits, devices, and apparatuses are described for auto-detection and adaptive configuration of high-definition multimedia interface (HDMI) ports. Unique systems and circuits allow HDMI repeaters to automatically detect if an HDMI device that has been connected thereto, via an HDMI port, is an HDMI source (source mode) or an HDMI sink (sink mode). The unique systems and circuits may be adaptively configured to allow the HDMI port to function as an HDMI input or an HDMI output based on the automatic detection. Methods corresponding to the functions performed by the systems and apparatuses are provided, and computer readable storage media with computer program instructions encoded thereon for enabling processing devices to perform the methods are also provided.

Abstract: Methods, systems, and apparatuses are described for source device detection. Source device detection may be performed for a variety of types of connectors such as cables or board/substrate connectors across which a DC voltage or stable presence signal is normally supplied during connections when the power signal of the connector is not present. An alternating power source is coupled to a capacitor of known capacitance via a switch. The capacitor is in series with an effective capacitance of a sink device, a connector, and a source device. When the switch is open, the voltage between the capacitor and the effective capacitor is read to determine if a source device is present and On, and when closed, if the source device is present and Off or in Stand-By, or not present. The methods, systems, and apparatuses described include tunability for the capacitor based on temperature and effective capacitance variations.

Abstract: Embodiments described herein automatically detect a power state of an electronic device and perform a control scheme based thereon. For example, a control device determines that an electronic device is to be in a desired power state. A socket device coupled to the electronic device determines an amount of current or power being provided to the electronic device and transmits an indication of the amount of current or power or a determined power state to the control device. Based on the indication, the control device determines the current power state of the electronic device. If the control device determines that the current power state is not the desired power state, the control device transmits a signal to the electronic device, which causes it to transition to the desired power state.
