In order to facilitate understanding of the scheme of the present application, a debugging method of the display device proposed in the present application is described below with specific embodiments. Fig. 6 is a flowchart illustrating a debugging method of a display device according to an embodiment of the present application, including the following steps.

In step S601, debug information is obtained, where the debug information at least includes a component identifier.

In specific implementation, the debugging information may be sent by the user through a control device, such as a combination key on a remote controller, or may be sent by a debugger through professional debugging equipment. That is to say, the scheme provided by the embodiment of the application is suitable for solving the abnormity of the display device in the development stage and also suitable for solving the abnormity of the display device after the display device leaves the factory.

And when the display device is abnormal, one, two, three or more functional components can be selected to be debugged, so that the debugging information can contain at least one component identification.

In step S602, a script file corresponding to the component identifier in the debugging information is determined according to the established correspondence between the component identifier and the script file.

In specific implementation, one script file is used for debugging all or part of functions of one functional component, so that more than one script file can exist in one functional component, in order to explain the relation between the script file and the functional component, the corresponding relation between the component identifier and the script file can be established in advance, and then the script file corresponding to each component identifier in the debugging information can be determined based on the corresponding relation.

Also, one script file may include any combination of a command to access middleware, a command to access a Hardware Abstraction Layer (HAL), a command to access an external service, and a command to directly access a serial service. That is to say, the script file may include diversified debugging commands to debug different types of objects or services, which is beneficial to improving the debugging completeness of the script file for corresponding functional components and obtaining richer exception analysis data, thereby improving the accuracy of subsequent exception analysis.

In step S603, the script file is executed to obtain the anomaly analysis data.

When the method is specifically implemented, the script file is analyzed, a plurality of debugging commands can be obtained, each debugging command has a safety level, the safety level is used for representing the influence degree of executing the debugging command on the abnormal state, then, the debugging commands are executed according to the sequence from high to low of the safety level, and the execution result of each debugging command is used as abnormal analysis data.

Therefore, the debugging commands with small influence degree on the abnormal state can be executed firstly, then the debugging commands with large influence degree on the abnormal state are executed, the debugging is carried out under the condition that the abnormal site is protected as far as possible, more accurate abnormal analysis data can be obtained, and the accuracy of subsequent abnormal analysis is improved.

In practical application, for the condition that the debugging information is sent by the user through the control device, such as the combined keys on the remote controller, a plurality of combined keys can be arranged on the remote controller, one combined key can trigger the execution of the debugging commands of all safety levels, and each of the other combined keys can trigger the execution of the debugging commands of one safety level. In this way, if the technician does not remotely guide, the user can try to trigger the execution of the debugging commands of all safety levels or part of the safety levels, and if the technician remotely guides, the user can trigger the execution of the debugging commands of certain safety levels only, so that the debugging flexibility is better.

Therefore, in some embodiments, the debugging information may further include security level indication information, in which case, after parsing the script file to obtain a plurality of debugging commands, a debugging command matching the security level indicated by the security level indication information may be screened from the plurality of debugging commands, and then, the screened debugging commands are executed in order from high to low in security level, and the execution result of each debugging command is used as the abnormal analysis data. Thus, the flexibility of debugging is better.

Further, when different functional components are debugged using debug commands having the same security level, a plurality of debug commands having the same security level can be executed in the order of the debug priority of the functional components from high to low.

Taking a channel component and a sound component in a display device to be debugged as an example, the performance of the sound component under different channels can be different, so the debugging of the sound component needs to be established on the premise that the channel component can normally switch channels, and in order to improve the debugging effectiveness of the sound component, the channel switching function of the channel component can be debugged first, and then the related functions of the sound component can be debugged. Of course, it is a precondition that the debug command for debugging the channel switching function corresponds to the same security level as the debug command for debugging the sound component-related function.

Therefore, the debugging priority of the channel component can be set to be higher, and the debugging priority of the sound component can be set to be lower, so that the debugging command corresponding to the channel component can be executed first, then the debugging command corresponding to the sound component can be executed, and the debugging reasonability can be improved.

Generally, each functional component has its own key register and key function, and the exception of a functional component is likely to be reflected on the value of the key register and the functional characterization data of the key function. The anomaly analysis data may include: the value of the key register corresponding to the component identifier in the debug information and the functional characterization data of the key function corresponding to the component identifier in the debug information, wherein, when the corresponding functional component is a sound component, the functional characterization data may be: the sound component carries out audio stream with preset duration before and after each audio processing flow; when the corresponding functional component is a display component, the functional characterization data may be: the display component displays the image frames before and after each image processing procedure.

Therefore, richer abnormal analysis data of the sound assembly and the display assembly can be obtained, the abnormal analysis of the sound assembly and the display assembly is facilitated, and the abnormal processing speed of the sound assembly and the display assembly is further promoted.

In step S604, the abnormality analysis data is saved in an external storage device.

During specific implementation, a mounting path of the storage device can be found first, and based on the component identifier, the security level number corresponding to the component identifier, and the time for acquiring the debugging information, a multilevel directory is constructed under the mounting path, that is, the multilevel directory is constructed in the storage device. For example, in order to distinguish debugging data at different times, a directory is constructed at the time of obtaining debugging information, a subdirectory is named under the directory by each component identifier, and in order to distinguish debugging commands of the same functional component with different security levels, a plurality of lower directories are constructed under each subdirectory.

Subsequently, when the abnormal analysis data is stored in the external storage device, mapping analysis can be performed on the basis of the locally specified directory, the security level of each debug command and the corresponding component identifier, so as to determine a directory in the multi-level directory, and further store the execution result of the debug command in the determined directory.

In the embodiment of the application, when the display device is abnormal (such as poor image quality and abnormal tone quality), the processor of the display device can be controlled to execute the script file for debugging, so that abnormal analysis data is obtained, and then the reason of the abnormality is analyzed, and a technician is not required to manually locate possible abnormal points, so that the abnormal processing speed of the display device can be increased. In addition, the functional components are debugged according to the granularity of the script file, the relevance between different functional components is relatively low, and the debugging flexibility is favorably improved.

In addition, it should be noted that the process of executing the debug command to debug the display device is also a process of resolving the exception, and the exception may be resolved after executing a certain debug command, or may not be resolved after executing all the debug commands. In any case, the anomaly analysis data can be used for locating and analyzing the anomaly cause.

The display device provided by the embodiment of the present application is described below with reference to specific embodiments.

Fig. 7 is a schematic diagram of a hardware structure of a display device according to an embodiment of the present disclosure, where a power supply is used to supply power to a main chip; the plug-in storage is used for providing storage service for the main chip; the signal input is used for providing a signal source for the main chip; a control input for switching a signal source of the main chip; the main chip is used for performing control processes such as signal processing, image quality/sound effect processing and output on an input signal source to complete an audio and video function, outputting a Low-Voltage Differential signaling (LVDS)/VBYONE to a screen, and outputting audio to a power amplifier.

In practical applications, the main chip is usually designed and developed by professional solution suppliers, and the internal processing flow is complex and is not disclosed externally. When the master chip has relatively complicated abnormality, a work team consisting of technical support engineers, service development engineers and scheme traders is required to follow up the processing. Sometimes, a special tool provided by a scheme supplier is needed to read the related information in the abnormal state. On-site conditions often hardly meet various requirements, and technical support engineers can only perform comparative analysis by means of plugging signal lines, switching channels, powering on and powering off and the like to locate and solve the abnormity. These methods are simple and rough, cannot solve complex problems and scene-related problems, and are not favorable for deep analysis of technicians. To this end, the embodiment of the present application provides a scheme for acquiring relevant data at the time of an abnormality by means of the display device itself.

Taking a storage device externally connected to the display device as an example, as a usb disk, fig. 8 is a schematic diagram of a process of debugging the display device according to an embodiment of the present application. The HDMI, the Digital Media Player (DMP), the Digital Television (DTV), the Analog Signal Television (ATV), and the Composite Video Baseband Signal (CVBS) (often called as Composite terminal or AV terminal because they commonly occur with an audio interface, and the CVBS is conventionally called as AV channel) are 5 switchable Signal channels of the display device, and the system component, the channel component, the display component, the sound component, and the backlight component are functional components in the display device, and each functional component may correspond to at least one script file, and the script file is written by a technician according to the functional characteristics of the functional module.

The USB flash disk identification is used for creating a working directory of the USB flash disk under the fixed directory according to the name and the safety level of the functional component, and a mapping relation exists between the fixed directory and an external connection path of the USB flash disk;

the channel management is used for switching the currently accessed channel of the display equipment based on the received channel switching instruction;

the script file analysis is used for analyzing the script file to obtain a plurality of debugging commands;

and the level classification is used for executing a plurality of debugging commands according to the sequence of the security level from high to low so as to finish debugging the middleware access service, the HAL layer access service, the external service and the serial port service, and storing the execution result of each debugging command into the U disk as abnormal analysis data, namely storing the execution result of the script file into the U disk as the abnormal analysis data.

It should be noted that, in fig. 8, only the channel component needs to select the script file corresponding to the current channel through channel management, and the other functional modules do not need to select the script file through channel management.

During specific implementation, when the display device is abnormal, if a technician can determine the functional component which possibly has a problem based on experience, the related functional components can be debugged only, and if the technician cannot determine the functional component which possibly has the problem based on experience, all the functional components can be debugged. That is to say, the technician can choose to debug some functional components and can choose to debug all functional components, so the flexibility of debugging is better.

In some embodiments, a script file corresponding to a functional component to be debugged may be acquired, the acquired script file may be parsed to obtain a plurality of debug commands, and the plurality of debug commands may be executed in an order from high to low according to the security level.

For example, the security level of the debug command is classified into three levels: the debugging command of the security level can safely acquire working state data of the display equipment, the debugging command of the risk level can realize a basic problem positioning processing flow and usually cannot damage an abnormal site, and the debugging command of the damage level can confirm a problem point in modes of switching channels, rapidly outputting modes and the like and usually damage the abnormal site. Then the debug commands may be executed in the order of the security level, the risk level, and the destruction level.

Considering that the amount of video stream data output by a display device is large, it is not practical to record the video stream when an abnormality occurs in the display device. Therefore, various types of test graphic cards (each test graphic card is an image with a special style) can be designed, a certain test graphic card is designed to be inserted into the appointed video processing node, if the test graphic card displayed by the display equipment is the same as the designed test graphic card, the subsequent processing flow of the appointed video processing node is considered to be normal, otherwise, the subsequent processing flow of the appointed video processing node is considered to be abnormal, and the abnormal node is checked node by node. The problem points of input signals, main chip processing and screen processing can be distinguished more quickly by the mode of the graphic card.

And the volume of the audio stream data output by the display equipment is relatively small, so that the audio data can be recorded in all or part of the audio processing nodes according to the requirement when the display equipment is abnormal, and then the waveform or sound of the recorded audio data is analyzed to judge which audio processing node has a problem. In addition, some audio processing nodes can be skipped by closing all or part of the processing flow of the audio processing nodes for the audio stream, and the audio processing nodes with abnormality are checked based on the audio stream after the audio processing nodes are skipped.

It should be noted that the debugging command for performing exception checking on the video stream or the audio stream is generally a risk level debugging instruction.

In specific implementation, each functional component has its own key register and key function, and the exception of the functional component is likely to be reflected from the value of the key register and the functional characterization data of the key function. The debugging result obtained by debugging each functional component may include: and the numerical value of the key register corresponding to the functional component and the functional representation data of the key function corresponding to the functional component. When the functional component is a sound component, the function representation data comprises audio streams of preset duration before and after each audio processing flow of the sound component; when the functional component is a display component, the functional characterization data includes image frames of the display component before and after each image processing procedure. Therefore, the method is favorable for accurately and visually expressing the abnormity of the types such as a screen splash, a screen flashing, abnormal color, popping and the like, and is also favorable for further improving the abnormity processing speed of the sound assembly and the display assembly.

Taking debugging of a technician as an example, fig. 9 is a flowchart of a debugging method of a display device according to an embodiment of the present application, including the following steps:

in step S901, debug information is acquired, and the debug information includes a component identifier.

In step S902, the channel name is updated according to the channel identifier of the current channel.

In step S903, it is determined whether the usb disk path is queried, and if not, the process proceeds to step S904, and if so, the process proceeds to step S905.

In specific implementation, if the display device is externally connected with a U disk, the path of the U disk (namely, the mounting path of the U disk) can be inquired, and if the display device is not externally connected with the U disk, the path of the U disk cannot be inquired.

In step S904, the present flow ends.

In step S905, a multi-level directory is constructed under the usb disk path according to the component identifier, the total number of corresponding security levels, and the debug time.

The debug time may be the time when the debug information is acquired.

In specific implementation, some functional components may have three security levels of debug commands, and some functional components may have two security levels of debug commands, so that the total number of security levels corresponding to different component identifiers may be the same or different.

Assuming that the component is identified as aaa and the total number of security levels is 3, the multi-level directory constructed in the usb disk may be as shown in fig. 10, wherein xxx represents a path name, and 1, 2, and 3 represent three security levels with successively lower security levels.

Assuming that the components are identified as aaa, bbb and the total number of security levels is 3, the multi-level directory constructed in the usb disk may be as shown in fig. 11, wherein xxx represents a path name, and 1, 2, and 3 represent three security levels with successively lower security levels.

In step S906, the local designation directory is mapped to the usb disk.

In step S907, the script file corresponding to the component identifier is read, and if the script file is successful, step S908 is performed, otherwise, step S904 is performed.

In specific implementation, if the user command is wrong or there is no script file corresponding to the component identifier, the reading will fail.

In step S908, the script file is parsed to obtain a plurality of debug commands.

In step S909, a plurality of debug commands are executed in order of security level from high to low to debug the serial port service, the middleware, the HLA layer, and the external service.

In step S910, the execution result of each debug command is saved in the multi-level directory.

In some embodiments, any combination of the following commands are contained in the script file:

the command of accessing the middleware, the command of accessing the hardware abstraction layer, the command of accessing the external service and the command of directly accessing the serial service.

In order to facilitate understanding of the scheme of the present application, the following describes an abnormality analysis method for a display device according to an embodiment of the present application. Fig. 13 is a flowchart illustrating a debugging method of a display device according to an embodiment of the present application, including the following steps.

In step S1301, anomaly analysis data is acquired from a storage device externally connected to the display device.

Taking a storage device externally connected with the display device as a U disk as an example, the U disk is connected to the analysis device, and the abnormal analysis data of the display device stored in the U disk can be obtained.

In step S1302, the cause of the abnormality of the display device is analyzed based on the abnormality analysis data.

Generally, methods for analyzing the cause of the abnormality include an exclusion method and a comparison method, and the two abnormality analysis methods are described below with reference to specific embodiments.

Elimination method-finding out abnormal points according to image processing flow or audio processing flow, and mainly checking the processing flow behind the abnormal points.

An image processing procedure provided in the embodiment of the present application is described below with reference to fig. 14.

A Multimedia Video Output Processor (MVOP), used in DTV and DMP channels, for encapsulating the data decoded by the front-end decoder into timing data, and sending the timing data to a scaling module (Scaler) at the back end;

the Input multiplexer (IP MUX) is mainly used for switching the Source of the signal Source and selecting which channel of the Source data is sent to the Scaler;

the Input end (Input, IP) is a signal inlet of the Scaler and is mainly used for signal detection;

an Output (OP) for video image processing, such as image zooming, resolution adjustment, etc.;

a Video Output Processor (VOP) which is an Output end of the Scaler and is used for generating Timing information required by a display screen (Panel) and providing data for the screen;

a Mixed Output Display (MOD) belongs to the back end of the Scaler and is used for setting registers and the like related to a display screen;

and the display screen driver (Panel TCON) is used for displaying input data on a screen.

As can be seen from the above process, the image processing process of the Scaler generally includes: and after processing links such as standardization, window scaling, image quality adjustment and the like are carried out on the input signals, outputting the input signals according to the screen specification. The logic details inside the Scaler are very complicated, and the difficulty of carrying out abnormal positioning only from the picture representation is very large. Therefore, the embodiment of the application provides a mode of testing the graphic card TestPattern to quickly locate the exception so as to reduce the exception checking range.

The principle of TestPattern: many image processing nodes can print TestPattern, and the image data input at the front end is replaced by the image data of the TestPattern, if the picture displayed on the display screen is good after a certain image processing node prints the TestPattern, the image processing node after the picture is good is indicated. It is worth noting that TestPattern replaces only valid image data, and Timing information follows the previous signal, e.g., 1080p @60hz for the current signal, and then TestPattern is also 1080p @60hz for Timing.

Assuming that the picture outputted to the screen after the DTV channel is signal-processed shows ghosting as shown in fig. 15, testPattern can be printed at the position Δ shown in fig. 14 by means of a plurality of debug commands, see fig. 16, the picture of TestPattern printed at different positions can be seen in the second column of images of fig. 16, and the picture displayed on the display screen after TestPattern printed at different positions can be seen in the third column of images of fig. 16.

Comparing the pictures of the TestPattern printed at the position delta behind the MVOP with the pictures of the TestPattern printed at the position delta behind the MVOP, which indicates that the flow behind the MVOP has problems, and then combining the pictures of the TestPattern printed at the position delta behind the IP with the problems, which indicates that the flow behind the IP has problems, and the pictures of the TestPattern printed at the position delta behind the OP and the VPD are normal, which indicates that the OP is abnormal. It should be noted that: the ghost dislocation phenomenon can only be shown on the TestPattern with changed content, and the pure TestPattern cannot see the abnormality, so the IPMUX and MOD cannot see the abnormality.

Contrast method-the difference between normal and abnormal is found according to all the information obtained by the image processing flow or audio processing flow analysis.

For example, when the HDMI channel is connected to a Personal Computer (PC) device, the resolution of the PC device is modified, and the problem of screen blurring may occur. The u8FRLRate parameter is FRL _3G _3Lwhen abnormal, and LEGACY _14 when normal, and finally, the FRL _3G _3Ltype signal processing abnormality is confirmed.

Similar methods can be used for audio streams, and are not described in detail herein.

It should be noted that: when the comparison method is used, the interference problem needs to be well handled, because some information is dynamically changed and cannot be used as a judgment basis. Therefore, the correct information can be captured more than twice, so that the interference information is eliminated as much as possible to find the information really influencing the result.
