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.

Source device detection

Embodiments described herein enable the transmission of infrared (IR) signals via an AV cable containing a plurality of signal lines. In embodiments, an IR receiver, and IR emitter, and/or logic circuitry may be integrated within an AV cable (e.g., an HDMI cable) to enable transmitting signals from an IR remote control device to a media device that may be located behind a physical obstruction through which IR signals are unable to pass. By utilizing one or more signal lines of an AV cable to transmit IR signals, existing AV communication protocols may continue to be utilized in a user's home entertainment system. In this manner, a user may be able to locate one or more media devices (e.g., home entertainment devices) in a physically remote location, such as in a cabinet or closet, without sacrificing any IR signaling functionality.

Methods, systems, and apparatuses are described for remote control device usage detection. A smart battery may be inserted into a remote control device. The smart battery provides power to the remote control device as well as monitors the power consumption when a particular one or more interface elements of the remote control is interacted with by an end user. The power consumption information is transmitted to a receiver, which may identify the remote control device and/or the interface element(s) that has been interacted with based on the received data.
