Abstract: Imaging capabilities of a remote control are leveraged to automatically identify a remotely controllable device and program the remote control accordingly. The remote control uses its built-in image device to obtain an image of a remotely controllable device. The image is processed and compared to a database to determine the specific type of device. Other variations include information of a location of the remote control and/or a location of a controllable device to facilitate in determining and controlling a device.

Abstract: A video processor is responsive to an output of a pair of cameras that are used for detetermining a viewer viewing direction of a display screen. Once the viewer's viewing angle crosses a threshold angular direction dynamically tracking pan function is enabled so as to shift the displayed picture. An enhanced audio processor makes the perceived sources of sound produce in speakers dynamically follow the shifted picture. As the displayed image shifts by the dynamically tracking pan function, the locations from which the sound is perceived to originate also track the displayed image so that the stereophonic width dynamically varies in accordance with the stereoscopic width.

Abstract: A video processor is responsive to an output of a pair of cameras that are used for determining a viewer viewing direction of a display screen. As long as the viewer's viewing angular direction is directed toward a center region of a display screen, the pan function is disabled. When the viewer's viewing angle crosses a first threshold angular direction away from the screen center, dynamically tracking pan function is enabled so as to shift the displayed picture. When the viewer's viewing angle crosses an even larger, second threshold angular direction, the picture will shift in the same direction but at a faster rate. When the viewer's viewing angular direction decreases in a manner to cross a threshold angular direction that is smaller than the first threshold angular direction further picture shift is suspended. Thereby, a hysteresis feature is incorporated.

Abstract: A method of operating a device for indicating an event notification to a user comprises indicating a new event through accordingly controlling visual, audible and/or tactile indicators. A user input is received in response to the indicated event. In case a user input in response to the indicated event is not received within a first time period, sensors in the device are controlled to monitor ambient conditions and determine corresponding pattern. In case of a change in the pattern of the ambient conditions by a predetermined amount within a second time period, the new event is indicated once more to the user.

Abstract: A method of handling telephone on-hold music, provided by a second party to a first party on a telephone connection between the first and the second party, includes detecting on-hold music, and providing, while on-hold music is detected, and to the first party, content from a source that is independent from the second party. A length of the most recently received audio signal originating from the second party is continuously stored. When on-hold music is no longer detected, voice information is retrieved from the stored length of the most recently received audio signal, providing, to the first party, content from a source that is independent from the second party is stopped, and the retrieved voice information is reproduced to the first party, wherein a time offset that corresponds to a time period required for detection of on-hold music is present.

Abstract: A method of creating a virtual keyboard is disclosed. The method comprises displaying the virtual keyboard on a touch screen in response to a user input; enabling a user to add a first virtual key to the virtual keyboard to form a first virtual keyboard; and storing in a memory the first virtual keyboard and a signature associated with the first virtual keyboard.

Abstract: A flexible hose user interface is used to promote sophisticated editing of video sequences in an easy manner. The flexible hose allows a user to visualize the effects of cropping on a frame by frame basis. A time axis action identifier aids the user in checking if desired objects are in all frames of the sequence. This is accomplished easily by dragging the time axis identifier through the flexible hose.
