Abstract
A method of diagnosing problems experienced with remote control operation of electronic devices includes monitoring background noise signals with a receiver of a signal processing electronic device, such as a set-top box, for use in receiving and rendering multimedia content via a separate display monitor. The electronic device has an internal remote control unit enabling remote control of the signal processing electronic device via wireless signals emitted from a separate remote controller. The background noise signals are analyzed with a signal processing unit residing in the electronic device. From the analysis, the electronic device generates a representation with respect to the background noise signals. The representation may be provided to the end user, technician or call center operator in a readily understandable form for purposes of readily verifying a noise interference problem and providing guidance with respect to mitigation. A device, such as a set-top box, is also disclosed.
