Abstract
Methods and apparatus for identifying the operating state of an audio-video (AV) device are described. Example methods and apparatus include monitoring messages transmitted via a data bus in a first AV device, wherein the data bus is communicatively coupled to a processor and an AV network controller of the first AV device, and wherein the AV network controller is further communicatively coupled to a second AV device external to the first AV device. The example method also involves extracting messages associated with an operation of the second AV device from the monitored messages, analyzing the extracted messages for data associated with an operating state of the second AV device, and sending a command to the AV network controller to request data missing from the extracted messages and associated with the operating state of the second AV device. Additionally, the example methods and apparatus include identifying the operating state of the second AV device by analyzing the extracted messages and a response from the second AV device associated with the command.
