Disclosed is a method for automatically adjusting synchronization of sound and picture of TV. The method includes: obtaining a video, determining whether the video contains an adjustment video clip corresponding to a preset video database; obtaining audio information of the adjustment video clip and a time point corresponding to the audio information if the video contains the adjustment video clip corresponding to the preset video database; comparing the audio information of the adjustment video clip and the time point corresponding to the audio information with a standard video in the preset video database, and determining whether there is a synchronization delay between the sound and the picture; and synchronizing the sound and the picture of the video if there is the synchronization delay between the sound and the picture. A device for automatically adjusting synchronization of sound and picture of TV and a computer readable storage medium are further disclosed.

A calibration apparatus according to the present invention includes: a first acquisition unit configured to acquire a first measurement value, which is a measurement value of light from a screen of a display apparatus; a second acquisition unit configured to acquire a second measurement value, which is a measurement value of external light to the display apparatus; an allowable range determination unit configured to determine an allowable range of the first measurement value based on the second measurement value acquired by the second acquisition unit; and a measurement value determination unit configured to determine whether the first measurement value acquired by the first acquisition unit is a value within the allowable range determined by the allowable range determination unit.

A set-top box (STB) determines an occurrence of a first STB error during operation of the STB, and identifies a first error code that corresponds to the first STB error. The STB maps the first error code to a first self-help video of multiple self-help videos stored at the STB, and plays back the first self-video via a display device coupled to the STB.

The present invention provides a gamma setting system for a display device including: an optical measuring unit measuring an optical property of a display device including an emissive display panel having red, green and blue sub-pixels; a control center performing a null setting step and an automatic setting step using the optical property of the display device; a system driving unit transmitting a result data between the display device and the control center; a first display unit displaying a TW target luminance, a TW target chromaticity and an RGB inherent chromaticity registered for the null setting step and the automatic setting step, a graph of a gray level voltage and a luminance of an RGB and a TW with respect to a gray level, a high level cell driving voltage (PVDD) and a low level cell driving voltage (PVEE) applied to an emitting element, a high level gamma source voltage (VDDH) and a low level gamma source voltage (VDDL) applied to a driving IC, a gamma slope, a contrast ratio, a driving type of the system, a gamma setting, an instruction on an execution command, and a progress state of the display device.

What is disclosed are systems and methods of optical correction for pixel evaluation and correction for active matrix light emitting diode device (AMOLED) and other emissive displays. Optical correction for correcting for non-homogeneity of a display panel uses sparse display test patterns in conjunction with a defocused camera as the measurement device to avoid aliasing (moiré) of the pixels of the display in the captured images.

Embodiments of the invention are directed to a system for generating video test pattern signals from definitions contained in a text-based definition file. The definition file allows the user to create generic definitions for test signals that can be interpreted to create test signals in a variety of formats, raster sizes, color spaces, sample structures, frame modes, and bit depths. A parametric generator uses one or more engines to then generate the desired test pattern from the definition file.

A method and system for monitoring video assets provided by a multimedia content distribution network (MCDN) includes an expert test monitoring platform (ETMP) configured to emulate MCDN client systems at a facility of an MCDN service provider. The ETMP may allow execution of ETMP scripts that specify remote control commands to send to a desired plurality of multimedia handling devices representing emulated MCDN clients. The ETMP scripts may be manually or automatically initiated and may be configured with execution parameters specifying, among other aspects, a number of iterations to repeat. Results recorded when the ETMP script executes may be retrieved and used to generate reports.
