TWO WAY COMMUNICATION BETWEEN AN APPLIANCE AND A REMOTE CONTROL

摘要

A method for storing and using information received from a controllable appliance in a controlling device. In response to a detected activation of a key of the controlling device the controlling device transmits a request signal to the controlled appliance for the purpose of retrieving from the controlled appliance data associated with a media tuning state of the controlled appliance, such as a tuned-to channel, CD or DVD track being played, or the like, The controlling device receives from the controlled appliance the media tuning state data and stores the media tuning state data in memory. The media tuning state data stored in the memory of the controlling device may then be used to transmit from the controlling device to the controlled appliance a media tuning command to cause the controlled appliance to replicate the previously captured media tuning state.
