Abstract
An add-on module is described. The add-on module is comprised of an attachment mechanism, an orientation detection subsystem, and a communication subsystem. The attachment mechanism is adapted to be usable by an end user of a display device to directly attach the add-on module to the display device. The orientation detection subsystem detects the rotational orientation of the display device. The communication subsystem communicates to a video source from which the display device receives a video signal notifications of the rotational orientation of the display device detected by the orientation detection subsystem. This enables the video source to, upon receiving each notification of the rotational orientation of the display device detected by the orientation detection subsystem, conform to the notification'"'"'s rotational orientation the rotational orientation of the video signal received from the video source.

3. A display system in which the rotational orientation of a video signal generated by a video source is automatically conformed to a rotational position of a display device, comprising:
-
the display device comprising; a video input interface that receives a video signal from the video source, and a display mechanism causing an image specified by the video signal to be visually displayed, and an add-on module that is directly physically attached to the display device by an end user, the add-on module comprising; an orientation detection subsystem that detects the rotational orientation of the add-on module, and a communication subsystem that communicates to the video source notifications of the rotational orientation of the add-on module detected by the orientation detection subsystem, such that the video source may, upon receiving each notification of the rotational orientation of the add-on module detected by the orientation detection subsystem, conform to the notification'"'"'s rotational orientation the rotational orientation of the video signal received from the video source.

26. A data transmission network conveying a display orientation data structure, the data structure containing an indication of a rotational orientation of an add-on module directly attached to a display device displaying an image that is predictably related to the rotational orientation of the display device, such that, if the data structure is received by a video source supplying the displayed image, the video source may rotate the displayed image it is supplying to correspond to the rotational orientation indicated by the data structure.

27. A video source device, comprising:
-
a video signal generation subsystem that generates a video signal based upon a video feed and a selected rotational orientation; a communication subsystem that receives rotational orientation signals from an add-on module physically attached to a display device receiving the video signal generated by the video signal generation subsystem; and a rotational orientation selection subsystem that periodically selects a rotational orientation correlated to the received rotational orientation signals.

28. A computer-readable medium containing a device driver for an add-on module for a display device, the device driver causing a computing system upon which it is installed to perform a method comprising:
-
receiving a message from the add-on module containing an indication of the rotational orientation of the add-on module; and if a rotational orientation maintained by the computing system and used by the computing system to generate a video signal is inconsistent with the indication of the rotational orientation of the add-on module, conforming the rotational orientation maintained by the computing system to the indication of the rotational orientation of the add-on module. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

36. An apparatus for reporting the rotation orientation of a display device, comprising:
-
a passive radio transponder adapted to be attached to the display device; and an active radio transceiver adapted to (a) determine, from a position proximate to the display device, the rotational orientation of the display device based upon radio communications with the passive radio transponder and (b) communicate the determined rotational orientation to a receiver. - View Dependent Claims (37, 38, 39, 40)
