In-flight entertainment systems provide entertainment for passengers on commercial airline flights. Presently, usually on longer flights, video entertainment is commonly available on in-flight passenger entertainment systems. In-flight entertainment systems can display video on a variety of display monitors ranging from a conventional CRT display to a more modern Liquid Crystal Display (LCD). Generally most displays are connected to the aircraft electronic system via a ARINC 722 connector. The ARINC 722 connector commonly provides an electrical interface between the aircraft and the video system, whether the video system is a CRT or LCD type monitor. With the increasing use of LCD monitors there is a greater need for the ability of the display monitor to be able to report its status. The need for status reporting is increased because the LCD monitors are often greater in number than the prior art CRT monitors and because malfunctions are less obvious. Several methods for providing status information from video displays have been proposed. Embodiments of the present invention comprise a system in which data can be requested by repeating commands, such as turn on, a number of times within a predetermined time interval. Because embodiments of the invention use an existing command, which can be the repeated without affecting the functioning of legacy systems, the need for modification of the airline and monitor systems is greatly reduced.

A novel process of visual calibration of a computer display or the like in volves adjusting the appearance and relative appearance of targets and su targets displayed on the display. An objective method is provided for determining the precisely optimal brightness setting for CRT displays, which method is also applicable to the setting of the “Black Level” control on some FPDs. A precise method is provided to visually determine conformity of a display's tonality to a given standard tone curve, for example a gamma 1.8 curve, which is embodied in one of the preferred calibration target sets. The need to sense and therefore be able to control and to verify the correct gray balance of the entire tone scale of the display is met. The problem of verifying the similarity of the tone curve in the display profile and that of the actual calibration is solved. By converting a preferred RGB gamma target into CIE Lab image data through an ideal display profile of the correct gamma, a new kind of target is taught.

There is provided a phase locked loop (PLL) having an improved phase unlock detection function. The PLL generates a clock pulse signal at a frequency from a synchronization signal of a cathode ray tube (CRT) monitor. The PLL includes a phase frequency detector (PFD), a charge pump, a loop filter, a Voltage Controlled Oscillator (VCO), a divider, a phase unlock detection circuit, a phase lock/unlock detection circuit, and an output circuit. The PFD compares a phase and frequency of a synchronization signal to that of a reference signal, and outputs an up or down signal. The charge pump outputs a pumping current in response to the up or down signal. The loop filter outputs a control voltage according to the pumping current. The VCO outputs a clock pulse signal having a frequency determined by a control voltage. The divider divides the clock pulse signal by a division ratio and outputs a reference signal. The phase unlock detection circuit detects an initial generation of a phase unlock from the up or down signal, outputs a first detection signal, and outputs an internal control signal according to the up or down signal. The phase lock/unlock detection circuit outputs a second detection signal, in response to the internal control signal and the first detection signal. The output circuit performs a logic operation on the first detection signal and the second detection signal and outputs a third detection signal. Therefore, the PLL having the improved phase lock/unlock detection function can improve system stability in mode switching of a CRT monitor, by quickly detecting an initial generation of phase unlock without a time delay.

Thus, an ''inverse'' light pen is provided which may be implemented at low costs and which may be used with non-CRT displays. Furthermore, the system is independent of the display screen size.

When any of push-button switches on a controller 40 is pressed in a sound input mode, a video game machine body 10 generates and temporarily stores frequency data of a tone corresponding to the pressed switch. At this time, when a joystick 45 on the controller 40 is tilted to a predetermined direction, the video game machine body 10 changes the generated frequency data according to the amount of tilt of the joystick 45. It is therefore possible to input various sounds in tone using a limited number of switches. The frequency data stored in the video game machine body 10 is read later to be converted into audio signals, and outputted from a speaker incorporated in a CRT display 30. When a melody based on the inputted sound coincides with a melody set in advance, the video game machine body 10 makes various changes in the progress of the game. For example, a hero character is warped to a position that is different from the present position, or provided with various items.
