  • Determining device state using state-detection circuit
    Patent number: 10097881
    Abstract: An audio/video (A/V) hub includes a state-detection circuit coupled to at least one pin in a high-definition multimedia-interface input connector, which can electrically couple to an entertainment device. When electrically coupled to the entertainment device, the state-detection circuit establishes a ground loop between the electronic device and the entertainment device. A control circuit in the A/V hub detects whether there is electrical coupling with the entertainment device using the state-detection circuit. When the electrical coupling is detected, the control circuit provides a set of first control commands associated with different types of entertainment devices until, in response, content activity is detected via the input connector.
