The present application provides a user configurable test system for set-top boxes (STB) and other consumer devices providing video output. In particular, it provides for a method of improving an Optical Character Recognition (OCR) process in such test systems.

An electronic device is provided. The electronic device may include a wired communication interface connected to a display device through a cable, and a controller that transmits a test signal, which includes specified data, to the display device through the wired communication interface and receives error check information regarding the test signal from the display device through the wired communication interface. The controller may sequentially change transmission characteristic values of the test signal within a specified range to transmit a plurality of test signals, and perform calibration for changing a transmission characteristic of a signal to be transmitted to the display device based on the error check information regarding the plurality of test signals.

Various arrangements for monitoring and utilizing solar conjunction events are presented. An occurrence of a solar conjunction event caused by the sun being substantially aligned with the satellite antenna through which a television receiver receives signals from one or more satellites may be monitored. A prediction of a future solar conjunction event based on the monitored occurrence of the solar conjunction event may then be calculated. A second occurrence of the solar conjunction event may be monitored. It may be determined that the second occurrence of the solar conjunction event does not match the calculated prediction of the future solar conjunction event within a threshold range. One or more features of the television receiver may be disabled in response to determining that the second occurrence of the solar conjunction event does not match the calculated prediction of the future solar conjunction event within the threshold range.

An display apparatus according to an embodiment of the present invention may includes a display panel on which an image is output; and a calibration device which is mounted on a rear surface of the display panel. The calibration device includes a housing, a drive motor which is disposed on an inside portion or an outside portion of the housing, a link assembly which is accommodated in the inside portion of the housing, which is capable of being withdrawn to the outside of the housing by power provided form the drive motor and which is provided to be capable of being bent or being rotated, and an photographing unit which is mounted on an end of the link assembly and photographs the image displayed on the display panel.

Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

The present application relates to set top boxes and relates to the inclusion of a diagnostic function in the set top box which may be activated remotely or respond internally to the detection of faults or changes in status. The diagnostic function may emulate key presses from an infrared remote control to perform a test.

A noise detection device of a display module, including: a storage module, a processing module and an encoding module; the storage module is used to store parallel video data, the processing module is used to transmit the stored parallel video data to the encoding module, the encoding module is used to convert the stored parallel video data into serial video data through encoding and to transmit the converted serial video data to a timing controller of a display module; the processing module is used to receive mini-LVDS data generated by the timing controller based on the converted serial data, and to convert the mini-LVDS data into the parallel video data; the processing module is used to compare the stored parallel video data with the converted parallel video data, and to determine whether the display module is qualified for noise control according to the comparison result.

A test apparatus for testing a video processing apparatus comprises means for receiving from the video processing apparatus a video output representative of a test sequence, the test sequence comprising a plurality of frames, each frame comprising an image of a respective different one of a plurality of frame identifiers; means for obtaining a sequence of sets of frame data from the video output, each set of frame data representative of a frame; and means for processing each set of frame data to determine the frame identifier for that frame.

An on-screen menu method and system for controlling the functions of integrated electronic devices and a television schedule system and method for displaying television schedule information on a television screen includes a program guide having a schedule information area that depicts the programs that are being presented on each channel at each time during the day and an interconnected series of menus to control the features of the integrated electronic devices. An input device allows the viewer to move a pointer over different interactive areas of the guide and the function performed when the area is activated is displayed in a contextual help window. Various control glyphs provide for recursive interaction with the guide.
