Disclosed example apparatus include activity detection circuitry to monitor for activity on a first bus of an (HDMI) port of the media device. Disclosed example apparatus also include probe circuitry to inject a message with a first address on the first bus in response to detection of no activity on the first bus for at least a threshold duration. Disclosed example apparatus further include state detection circuitry to detect the operational state of the media device based on whether a response to the message is received on the first bus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting an operational state of a media device","description":"Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to detect an operational state (such as an on/off state) of a media device are disclosed herein.
