An example method includes extracting, at a first AV device, data communicated via a data bus coupling a processor of the first AV device to a HDMI interface, the HDMI interface coupled to a second AV device different than the first AV device; analyzing a temporal sequence of the extracted data to determine if additional information is needed from the second AV device to identify a current operating state of the second AV device; when the temporal sequence is missing an expected message related to the current operating state of the second AV device, causing an AV network controller of the first AV device to request information from the second AV device; and analyzing a response from the second AV device including the requested information to identify the current operating state of the second AV device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for determining the operating state of audio-video devices","description":"Methods and apparatus for identifying an operating state of an AV device are described.
