Abstract: Disclosed are various systems and methods of color space setting adjustment. In one embodiment, a system includes an LED RGB backlight as well as a color gamut mapping engine configured to adjust a plurality of input values and output a plurality of adjusted input values to an LCD panel having a native transfer function such that the transformation of the adjusted input values to visible light displayed by the LCD panel complies with user defined color space settings.

Abstract: A source unit has a video source, a digital audio source, a DDC/CI communications capability and a switch for coupling a pin of a standard video cable either to the digital audio source or to a non-audio conventional connection. A display device has a video consumer, a digital audio consumer, a DDC/CI communications capability and a switch for coupling the pin of the standard video cable either to the digital audio consumer or to a non-audio conventional connection. The switch in the display device is responsive to a DDC/CI command.

Abstract: An image display adjustment system comprises a display setup application executable by a processor and configured to, in response to detecting at least one characteristic associated with a display device, automatically cause an adjustment image to be displayed on the display device and an image adjustment process to be performed for the display device using the adjustment image.

Abstract: A source unit is configured to receive its main power supply from pin 14 of a DVI-compliant cable connector. A display device is operable to connect its power supply to pin 14 of a DVI-compliant cable connector to accommodate the main power requirements of a source unit.

Abstract: A copy protection method and apparatus is provided to inhibit unauthorized viewing or copying of a video signal. A varying set of additional or invalid video pulses are generated onto a typical video signal. A pulse sequence identifier identifies the location of the invalid or additional pulses and is likewise generated onto the video signal prior to the occurrence of the identified pulses. The combined signal is received at an authorized display which then decodes or filters the additional or invalid portion of the video signal from the original signal according to a decode protocol stored in local memory. A resultant video output signal is guaranteed from only the original signal.

Abstract: An interconnectivity scheme for a PC Theatre system includes the use of compatible plug and display connectors on both the display and the host computer. Audio/video signals received by either the display or the computer may be processed by the computer and transmitted between these devices in a standardized signal format using the compatible connectors. The control scheme for facilitating master-slave control of the display by the computer includes the use of various standardized signals and formats as well to ensure compatibility between products manufactured by different companies.

Abstract: Apparatus, and an associated method, selects parameters determinative of video display characteristics of video displays displayable upon a video monitor. The parameters, such as brightness and contrast parameters, are stored at the video display monitor. The video display monitor is connected to a computer system unit. During booting operations, the video display parameters are retrieved by the computer system unit and selectably used to determine the video display characteristics of video displays displayable upon the video display monitor.

Abstract: A programmable remote control is implemented using a standard personal computer. The computer controls the output of, for example, an infrared transmitter to control various devices such as televisions, stereos, videocassette recorders or cd players. The computer can alter the type of commands issued from the transmitter based upon a command structure stored on a hard disk within the computer. This database is updatable from a variety of sources.

Abstract: A convergence device system comprising a display monitor subsystem, a computer subsystem coupled to the display monitor subsystem, and a convergence functionality module adapted to provide a video signal to the computer subsystem. The display monitor subsystem is selectably operable in one of a first functional mode and a second functional mode, responsive to a control signal generated by the computer subsystem, wherein each of the modes corresponds to a set of selected display settings for the display monitor subsystem.

Abstract: A computer system adapted to receive and interpret signals from a remote control. The signals received from the remote control are interpreted and transformed into signals equivalent to those produced by a computer keyboard.

Abstract: A remote control input device for use with a computer system is disclosed. The remote control input device typically includes means for wirelessly connecting the remote control input device to the computer system, a trackball, coupled to the connecting means for manipulating a pointing icon displayed on the video monitor, and a power source that powers the remote control input device. The remote control input device further includes a power management means for managing the power of the power source by monitoring the status and activity of the trackball used on the remote control input device. The remote control input device typically includes a first set of keys that provide input to the computer system and a second set of keys that are assigned to the trackball that control the pointing icon manipulated by the trackball.

Abstract: An apparatus and method for recovering "break" codes transmitted by a keyboard that are not properly received by the receiver of the computer system. The keyboard is an infrared keyboard that transmits to a receiver in the computer system "make" codes when the keys are depressed and transmits to the receiver "break" codes when the keys are released. Upon receipt of the "make" and "break" codes, the receiver keeps track of the status of each of the keys, i.e., depressed or released, by updating a database in response to receipt of the "make" and "break" codes. At select time intervals, the keyboard transmits to the receiver an "idle" code containing data corresponding to the status of each key. Upon receipt of the "idle" code, the receiver compares the "idle" code with the status of each key as indicated by the data base. The receiver then generates a "break" code for each of the keys that do not compare.

Abstract: A computer system having a wireless keyboard which transmits make-break signals to the computer system. The wireless keyboard and/or computer system being adapted to have television (or other remotely controllable devices) commands mapped into the wireless keyboard such that the wireless keyboard can provide standard computer keyboard commands to the computer and also remotely control another remotely controllable device.
