Abstract
Systems and methods for controlling devices remotely by embedding command information within video signals. The command information includes gestures or icons which are imbedded into the video signal and enable the user to interpret the command information by viewing the icon or gesture on a monitor or display device. By viewing the monitor or display device, the user can determine what command information is conveyed within the video signal. Further, imbedding the visually interpretable icon or gesture within the video signal facilitates transmitting the video signal having the command information imbedded therein using analog to digital conversions and reconversions and transmission through any of a various number of switching networks. The remote devices may by any of a number of electronically controlled electrical or mechanical devices. A device controller at the remote end receives, the decoded command information and generates the appropriate commands to operate the controlled device.
