Therefore, before putting products containing video modules on the market, it is very important to test the quality of the video played by the video module.

[0003] Currently, the quality of the video played by the video module is mainly tested by manual observation. However, manual observation is prone to missed judgments due to visual fatigue of the inspectors, resulting in the outflow of abnormal products; and because the inspection needs to be carried out by the inspectors watching the video, it takes a certain amount of time to play the video, resulting in low inspection efficiency. Summary of the invention

[0010] Compared with the prior art, the technical solution of the embodiment of the present invention has the following advantages:

[0011] The assembled product provided by the embodiment of the present invention includes a storage module and a video module, wherein the storage module stores data of a preset standard video and standard frame data corresponding to the preset standard video, wherein the video module is suitable for collecting the preset standard video output by the storage module, and outputting the frame data to be tested of a specific frame based on the preset standard video, wherein the frame data to be tested and the standard frame data have the same frame sequence number in the preset standard video. Therefore, by improving the assembled product, the storage module stores data of the preset standard video and the standard frame data, so that the video module can output the frame data to be tested having the same frame sequence number as the standard frame data, thereby enabling the assembled product to compare the frame data to be tested with the standard frame data in the assembly test process, so as to realize automatic detection of the video module.

Compared with the manual detection scheme, this is conducive to improving the detection reliability and detection efficiency of the video module.

[0017] As can be seen from the background technology, currently, the quality of video images played by the video module is mainly detected by manual observation, resulting in that the detection reliability and detection efficiency of the video module need to be improved.

[0018] In order to solve the technical problem, an embodiment of the present invention provides a video module detection method, which is suitable for detecting an assembled finished product, wherein the assembled finished product includes a storage module and a video module, wherein the storage module stores data of a preset standard video and standard frame data corresponding to the preset standard video, and the detection method includes: causing the storage module to output a preset standard video; causing the video module to capture the preset standard video, and outputting test frame data of a specific frame based on the preset standard video, wherein the test frame data and the standard frame data have the same frame sequence number in the preset standard video; and comparing the test frame data with the standard frame data having the same frame sequence number to obtain a comparison result.

[0019] Since the storage module stores the data of preset standard videos and standard frame data, the video module can output the frame data to be tested having the same frame number as the standard frame data, thereby enabling the comparison of the frame data to be tested with the standard frame data in the assembly test process through the assembled finished product to realize automatic detection of the video module. Compared with the manual detection scheme, this is conducive to improving the detection reliability and detection efficiency of the video module. Moreover, since the storage module and the video module have constituted the assembled finished product, the quality of the video module in the assembly test process can be detected, so that the assembled finished product with abnormal video module can be quickly and effectively intercepted in the assembly test process according to the test results.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] refer to Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of an assembled finished product of the present invention.

[0022] In this embodiment, the assembled product 100 includes: a storage module 125 and a video module 135; wherein the storage module 125 stores data of a preset standard video and standard frame data corresponding to the preset standard video; the video module 135 is suitable for collecting the preset standard video output by the storage module 125, and outputting the frame data to be tested of a specific frame based on the preset standard video, and the frame data to be tested and the standard frame data have the same frame number in the preset standard video.

[0023] In this embodiment, the assembled product 100 further includes a circuit board 110 , and the storage module 125 and the video module 135 are disposed on the circuit board 110 .

[0024] The circuit board 110 is used to provide electrical signals to various components (eg, various chips) mounted thereon or to implement interaction between the various components.

[0025] In this embodiment, the circuit board 110 is a printed circuit board (PCB), and accordingly, the assembly structure 100 is a PCBA (Printed Circuit Board Assembly) finished product.

[0026] It should be noted that PCBA is a structure obtained by mounting components on a PCB board using surface mount technology (SMT) and then using a dual in-line package (DIP).

[0027] In other embodiments, the assembled product may also be other types of finished products depending on the assembly method.

[0028] In this embodiment, the assembled product 100 further includes a chip disposed on the circuit board 110 .

[0029] As an example, the chips disposed on the circuit board 110 include a storage chip 120 and a video main control chip 130 .

[0030] In this embodiment, the memory chip 120 and the video main control chip 130 are disposed on the circuit board 110 by surface mounting technology. In other embodiments, the memory chip and the video main control chip can also be disposed on the circuit board by other methods.

[0031] In this embodiment, the assembled product 100 has a signal receiving port 111 , and the signal receiving port 111 is suitable for receiving a test instruction from the outside, and the test instruction is used to drive the video main control chip 130 , thereby controlling other chips through the video main control chip 130 .

[0032] By providing a signal receiving port 111 on the assembled product 100 , the assembled product 100 can be tested in an assembly test process, thereby achieving automatic detection of the video module 135 .

[0033] Furthermore, the signal receiving port 111 is adapted to receive a test instruction, so that the video main control chip 130 can be started in response to the test instruction.

[0034] In this embodiment, the assembled product 100 further has a power port 112, and the power port 112 is suitable for receiving a power signal that can start the assembled product 100. Specifically, the power port 112 is suitable for coupling with a power source.

[0035] In this embodiment, by improving the assembled finished product 100, the storage module 125 stores data of a preset standard video and standard frame data corresponding to the preset standard video, so that the video module 135 is suitable for collecting the preset standard video output by the storage module 125, and outputting the frame data to be tested of a specific frame based on the preset standard video. The frame data to be tested and the standard frame data have the same frame sequence number in the preset standard video, so that the assembled finished product 100 can be used to compare the frame data to be tested with the standard frame data in the assembly test process to achieve automatic detection of the video module 135. Compared with the manual detection solution, this is conducive to improving the detection reliability and detection efficiency of the video module 135. Moreover, since the storage module 125 and the video module 135 have constituted the assembled finished product 100, the quality of the video module 135 in the assembly test process can be detected, so that according to the test results, the assembled finished product 100 with abnormal video module 135 can be quickly and effectively intercepted in the assembly test process, thereby reducing the probability of abnormal assembled finished products 100 flowing into the market.

[0036] Moreover, the storage module 125 and the video module 135 are integrated in the same assembled product 100 (specifically, they are arranged on the same circuit board 110). On the one hand, the speed of interaction between the storage module 125 and the video module 135 is improved, and the speed of the video module 135 capturing preset standard videos is correspondingly improved. On the other hand, it is also beneficial to reduce the complexity of interaction between the storage module 125 and the video module 135.

[0037] In addition, the storage module 125 stores data of a preset standard video and standard frame data corresponding to the preset standard video. Therefore, when the assembled finished product 100 is inspected, each assembled finished product 100 can obtain an inspection result based on the same preset standard video and the same standard frame data, thereby improving the reliability of the inspection.

[0038] Because the storage module 125 has stored the data of the preset standard video and the standard frame data corresponding to the preset standard video before the inspection, when entering the inspection process, the inspection personnel do not need to write the preset standard video data and the standard frame data to each assembled finished product 100, nor do they need to call the standard video data and the standard frame data from outside the assembled finished product 100, thereby enabling automatic inspection of the assembled finished product 100 and improving inspection efficiency.

[0039] Again, since the detection object of the detection method is the assembled finished product 100, a chip has been set on the circuit board 110, so the storage module 125 in the assembled finished product 100 can be used to store the data of the preset standard video and the standard frame data corresponding to the preset standard video.

[0040] In this embodiment, the assembled product 100 further includes a video main control chip 130 disposed on the circuit board 110 , and the video main control chip 130 is used to control the entire assembled product 100 .

[0041] In this embodiment, the type of the video main control chip 130 includes a central processing unit (CPU) chip or a system on chip (SOC) chip.

[0042] In this embodiment, the chip on the circuit board 110 includes a storage chip 120 for providing the storage module 125, and the storage module 125 and the video module 135 are integrated into different chips. In other words, the storage module 125 is provided by the storage chip 120, and the video module 135 is provided by the video main control chip 130, and the storage chip 120 and the video main control chip 130 are different chips.

[0043] By using another chip to store the data of the preset standard video and the standard frame data corresponding to the preset standard video, the changes to the design of the video main control chip 130 itself can be reduced.

[0044] Correspondingly, in this embodiment, the storage module 125 (ie, the storage chip 120 ) is controlled by the video main control chip 130 .

[0045] In other embodiments, the storage module may also be integrated into the video main control chip.

[0046] Specifically, the storage module 125 is also pre-set with a video playback unit, and the data of the preset standard video is stored in the video playback unit. When the video main control chip 130 sends a play instruction to the storage module 125, the storage module 125 responds to the play instruction and triggers the video playback unit to play the preset standard video, thereby outputting the prefabricated standard video. In other words, the video main control chip 130 responds to the test instruction to control the storage module 125 to output the preset standard video.

[0047] It should be noted that the video playback unit here refers to a unit written in a program and capable of playing videos. In other words, the video playback unit is video playback software.

[0048] Moreover, the storage module 125 also stores standard frame data corresponding to the preset standard video, so as to serve as reference data for subsequent detection of whether the playback quality of the video module 135 meets the requirements.

[0049] It should be noted that the standard frame data refers to: frame data obtained based on a video module 135 of qualified quality. Accordingly, when the video module 135 is tested, if the frame data to be tested actually played by the video module 135 can be successfully compared with the standard frame data, it means that the quality of the video module 135 being tested meets the requirements.

[0050] In this embodiment, the memory chip 120 needs to meet the characteristics of not losing data after power failure and having a large storage capacity. If the assembled product 100 is to be able to operate, various system software needs to be pre-installed in the storage module 125. Therefore, if the selected memory chip is a chip that loses data once power is lost, the assembled product 100 will not be able to operate and cannot be tested accordingly.

[0051] To this end, in this embodiment, the type of the storage chip 120 includes an embedded multimedia card (EMMC) chip, an electrically erasable programmable read only memory (EEPROM) chip or a ferroelectric RAM (FRAM) chip.

[0052] As an example, the type of the memory chip 120 is an embedded memory chip.

[0053] In this embodiment, the storage module 125 stores preset standard videos of one or more formats and standard frame data of corresponding formats, and the formats of the preset standard videos are compatible with the video module 135 in the video main control chip 130 .

[0054] The video module 135 is integrated in a video chip. Specifically in this embodiment, the video chip is the video main control chip 130 .

[0055] The video module 135 of the video main control chip 130 can play videos of a specific format. Therefore, the format of the preset standard video is compatible with the video module 135 of the video main control chip 130, so that the video module 135 can parse the data of the preset standard video.

[0056] When the storage module 125 stores preset standard videos of multiple formats, the preset standard videos and standard frame data correspond one to one, that is, a preset standard video of one format corresponds to the standard frame data of the format, so as to detect the playback quality of videos of each format by the video module 135.

[0057] In this embodiment, the format types of the preset standard video include one or more of H264 video, H265 video and VP9 video. It is understandable that the format types of the preset standard video are not limited to the above-mentioned types. In other embodiments, according to the performance of the video module, the preset standard video stored in the storage module can also be other available formats.

[0058] In this embodiment, the standard frame data includes a standard frame image.

[0059] In this embodiment, the storage module 125 only stores the standard frame data of a specific frame of the preset standard video (that is, only stores one standard frame image).

[0060] By storing only the standard frame data of a specific frame, the efficiency of subsequent comparison is improved. Moreover, if there is a problem with the video module 135, the frame image of each frame will be abnormal, so even if only the standard frame data of one frame is selected for comparison, a reliable detection result can still be obtained.

[0061] Specifically, the specific frame is the first frame of the preset standard video. The video module 135 decodes and generates frame data of the specific frame and downloads it. Therefore, selecting the first frame is beneficial to saving test time.

[0062] In other embodiments, the standard frame data of any other frame in the preset standard video may also be stored, for example, the second frame or the last frame, etc. In other embodiments, according to actual needs (for example, to further improve the reliability of the detection result), the standard frame data of each frame of the preset standard video may also be stored for subsequent frame-by-frame comparison.

[0063] In this embodiment, the storage module 125 further stores a preset comparison instruction, and the storage module 125 is further adapted to compare the frame data to be tested with the standard frame data according to the preset comparison instruction to obtain a comparison result.

[0064] By pre-storing instructions for comparing the frame data to be tested with the standard frame data in the storage module 125, the storage module 125 also has the function of comparing the frame data to be tested with the standard frame data. Therefore, there is no need to set up an additional comparison module outside the assembled product 100, thereby further realizing automatic detection, improving detection efficiency, and reducing changes to existing detection devices.

[0065] It should be noted that the preset comparison instruction is performed through a preset software code, and the preset software code is stored in the storage module 125 .

[0066] Specifically, the storage module 125 is adapted to compare the frame data to be tested with the standard frame data of the same format type according to the preset comparison instruction.

[0067] In this embodiment, the storage module 125 is controlled by the video main control chip 130 , so the video main control chip 130 controls the storage module 125 to perform comparison according to the preset comparison instruction.

[0068] The assembled product 100 further includes a video main control chip 130 disposed on the circuit board 110 . The video main control chip 130 includes a video module 135 , so that the assembled product 100 can realize a video playback function through the video main control chip 130 .

[0069] In this embodiment, the video module 135 is controlled by the video main control chip 130 .

[0070] It should be noted that the video main control chip 130 not only integrates the video module 135, but also integrates other functional modules, such as network port, HDMI (High Definition Multimedia Interface), CVBS (Composite Video Broadcast Signal), USB (Universal Serial Bus), codec module, GPU (Graphics Processing Unit) and other modules.

[0071] By using the video main control chip 130, that is, integrating the main control chip and the video chip into one chip, there is no need to use hardware circuit design to control the video chip through another main control chip, so it can avoid introducing other influencing factors, such as the influence of PCB design, the influence of routing, the influence of production process, the influence of chip supporting peripheral circuits, etc. In addition, the video main control chip 130 integrates the video module 135 inside the main control chip, and the video main control chip 130 can quickly call the function of the video module 135.

[0072] It should be noted that, in other embodiments, according to design requirements, the video module may also be integrated into another video chip different from the main control chip.

[0073] The video module 135 is used to parse and process video data to output video images.

[0074] In this embodiment, the frame data to be tested output by the video module 135 has the same frame sequence number as the standard frame data, so that the comparison between the frame data to be tested and the standard frame data is meaningful, so that it is possible to judge whether the quality of the video module 135 meets the requirements based on the comparison structure.

[0075] In this embodiment, the standard frame data includes a standard frame image, and the frame data to be tested correspondingly includes a frame image to be tested, that is, the data types of the frame data to be tested and the standard frame data are the same, so they can be compared.

[0076] Correspondingly, the video module 130 includes a decoding unit (not shown), which is suitable for decoding the collected preset standard video and obtaining a frame image to be tested of a specific frame as the frame data to be tested.

[0077] It should be noted that when the storage module 125 stores preset standard videos of multiple formats, the decoding unit may include multiple decoding sub-units, and the decoding sub-units correspond to the format types one by one, so as to decode the preset standard videos of each format type.

[0078] In this embodiment, the video module 130 outputs the frame data to be tested having the same frame number according to the frame number corresponding to the standard frame data.

[0079] In this embodiment, the storage module 125 only stores the standard frame data of a specific frame in the preset standard video, and correspondingly, the video module 130 outputs the frame data to be tested of the specific frame.

[0080] Specifically, the specific frame is the first frame of the preset standard video.

[0081] It should be noted that the storage module 135 stores preset standard videos of one or more formats and standard frame data of corresponding formats, and the format types of the preset standard videos are compatible with the video module. Therefore, the video module 135 is suitable for outputting the frame data to be tested of the corresponding format type based on the data of the preset standard videos of each format type.

[0082] Correspondingly, the video main control chip 130 is suitable for respectively calling the data of preset standard videos of various formats, and obtaining the frame data to be tested of the corresponding format through the video module 135 .

[0083] In the case where preset standard videos of multiple formats are stored in the storage module 135, it is necessary to enable the video module 135 to output the test frame data of the corresponding format type based on the data of the preset standard videos of each format type, so as to detect whether the video module 135 can normally play videos of each format type.

[0084] Correspondingly, an embodiment of the present invention also provides a method for detecting a video module.

[0085] It should be noted that, in this embodiment, the detection method is suitable for detecting an assembled finished product, wherein the assembled finished product includes a storage module and a video module, wherein the storage module stores data of a preset standard video and standard frame data corresponding to the preset standard video.

[0086] The storage module and the video module are integrated into the same assembled product. On the one hand, this improves the speed of interaction between the storage module and the video module, and correspondingly improves the speed at which the video module captures the preset standard video. On the other hand, it is also beneficial to reduce the complexity of interaction between the storage module and the video module.

[0087] Specifically, the assembled product includes a circuit board, and the storage module and the video module are arranged on the circuit board.

[0088] Combined with reference Figure 1 In one embodiment, the detection method is suitable for detecting the assembled finished product 100 described in the above embodiment.

[0089] In this embodiment, the assembled product 100 includes a chip disposed on the circuit board 110 .

[0090] Specifically, the assembled product 100 includes a video main control chip 130 disposed on the circuit board 110, and the video main control chip 130 is used to control the entire assembled product 100. Accordingly, the storage module 125 and the video module 135 are both controlled by the video main control chip 130.

[0091] As an example, the chips on the circuit board 110 include a storage chip 120 and a video main control chip 130 .

[0092] In this embodiment, the circuit board 110 is a printed circuit board, and accordingly, the assembly structure 100 is a PCBA finished product. In other embodiments, the assembled finished product may also be other types of finished products.

[0093] In this embodiment, the memory chip 120 is used to provide the memory module 125 . In other words, the memory module 125 is the memory chip 120 .

[0094] In this embodiment, the video main control chip 130 and the storage chip 120 for storing data of preset standard videos and standard frame data are different chips, thereby reducing the changes to the design of the video main control chip 130 itself.

[0095] The detailed description of the assembled product 100 can be combined with the relevant description of the aforementioned embodiment, which will not be repeated here.

[0096] Combined with reference Figure 2 and Figure 3 , Figure 2 is a flow chart of an embodiment of a method for detecting a video module of the present invention, Figure 3 It is a structural schematic diagram of an embodiment of a test system corresponding to the detection method of a video module of the present invention.

[0097] Step S1 is executed to enable the storage module 125 to output the pre-made standard video.

[0098] By making the storage module 125 output the prefabricated standard video, the video module 135 can subsequently capture the preset standard video and output the frame data to be tested of a specific frame based on the preset standard video, thereby preparing for subsequent comparison.

[0099] In this embodiment, the storage module 125 (ie, the storage chip 120 ) is controlled by the video main control chip 130 .

[0100] In this embodiment, a video playback unit is pre-set in the storage module 125, and the data of the preset standard video is stored in the video playback unit. When the video main control chip 130 sends a play instruction to the storage module 125, the storage module 125 responds to the play instruction and triggers the video playback unit to play the preset standard video, thereby outputting the prefabricated standard video. In other words, the video main control chip 130 responds to the test instruction and controls the storage module 125 to output the preset standard video.

[0101] It should be noted that the video playback unit here refers to a unit written in a program and capable of playing videos. In other words, the video playback unit is video playback software.

[0102] Specifically, enabling the storage module 125 to output the pre-made standard video includes enabling the storage chip 120 to respond to a play instruction from the video main control chip 130 and play the pre-made standard video through a preset play unit.

[0103] The storage module 125 also stores standard frame data corresponding to the preset standard video, so as to serve as reference data for subsequent detection of whether the playback quality of the video module 135 meets the requirements.

[0104] In this embodiment, the storage module 125 stores preset standard videos of one or more formats and standard frame data of corresponding formats, and the formats of the preset standard videos are compatible with the video module 135 of the video main control chip 130 .

[0105] The video module 135 of the video main control chip 130 can play videos of a specific format. Therefore, the format of the preset standard video is compatible with the video module 135 of the video main control chip 130, so that the video module 135 can parse and process the data of the preset standard video.

[0106] In this embodiment, the format types of the preset standard video include one or more of H264 video, H265 video and VP9 video. It is understandable that the format types of the preset standard video are not limited to the above-mentioned types. In other embodiments, according to the performance of the video module, the preset standard video stored in the storage module can also be other available formats.

[0107] In this embodiment, the standard frame data includes a standard frame image.

[0108] In this embodiment, the storage module 125 only stores the standard frame data of a specific frame of the preset standard video (that is, only stores one standard frame image).

[0109] By storing only the standard frame data of a specific frame, the efficiency of subsequent comparison is improved. Moreover, if there is a problem with the video module 135, the frame image of each frame will be abnormal, so even if only the standard frame data of one frame is selected for comparison, a reliable detection result can still be obtained.

[0110] Specifically, the specific frame is the first frame of the preset standard video. The video module 135 decodes and generates frame data of the specific frame and downloads it. Therefore, selecting the first frame is beneficial to saving test time.

[0111] In other embodiments, the standard frame data of any other frame in the preset standard video may also be stored, for example, the second frame or the last frame, etc. In other embodiments, according to actual needs (for example, to further improve the reliability of the detection result), the standard frame data of each frame of the preset standard video may also be stored for subsequent frame-by-frame comparison.

[0112] Correspondingly, in step S1, the storage module 125 is enabled to output prefabricated standard videos of corresponding formats based on the data of the preset standard videos of various formats.

[0113] That is to say, when performing the detection, according to the quality detection requirements of the video module 135 under the specific format type video, the pre-made standard video of the corresponding format type is output. For example, the storage module 125 is made to output the data of the preset standard video in the H264 format, and after comparing the frame data to be tested of the format type with the standard frame data, the storage module 125 is made to output the preset standard video in the H265 format. That is to say, for each format type, the steps of making the storage module 125 output the pre-made standard video to the comparison step are respectively performed.

[0114] In this embodiment, the storage module 125 further stores a preset comparison instruction, and the storage module 125 is further adapted to compare the frame data to be tested with the standard frame data according to the preset comparison instruction to obtain a comparison result.

[0115] By pre-storing instructions for comparing the frame data to be tested with the standard frame data in the storage module 125, the storage module 125 also has the function of comparing the frame data to be tested with the standard frame data. Therefore, there is no need to set up an additional comparison module outside the assembled product 100, thereby further realizing automatic detection, improving detection efficiency, and reducing changes to existing detection devices.

[0116] It should be noted that the preset comparison instruction is performed through a preset software code, and the preset software code is stored in the storage module 125 .

[0117] In this embodiment, enabling the storage module 125 to output the pre-made standard video includes: driving the storage module 125 through the video main control chip 130 and calling the pre-made standard video.

[0118] Under the control of the video main control chip 130 , the storage module 125 plays the pre-made standard video, thereby outputting the pre-made standard video to the video module 135 .

[0119] Continue to refer Figure 2It should be noted that before the storage module 135 outputs the prefabricated standard video, it also includes: executing step S02, inputting a test instruction to the assembled product 100, so that the video main control chip 130 responds to the test instruction and starts.

[0120] During the detection process, a test instruction for the storage module 135 is pre-set to implement the detection of the quantitative production of the assembled finished product 100.

[0121] The video main control chip 130 is made to respond to the test instruction and start up, so that the video main control chip 130 controls the storage module 125 to output the prefabricated standard video and controls the video module 135 to capture the preset standard video.

[0122] Specifically, in conjunction with reference Figure 3 , the detection method is performed by a test fixture 200.

[0123] The test fixture 200 can be regarded as a detection device. The test fixture 200 stores test instructions for detection of different items. The test fixture 200 is used to play a main control role in the detection process.

[0124] Therefore, before inputting the test instruction to the assembled product 100 , the inspection method further includes: coupling the assembled product 100 with the test tool fixture 200 so as to achieve interaction between the assembled product 100 and the test tool fixture 200 .

[0125] Specifically, Figure 3 As shown, the test fixture 200 has a signal output port 211, and the signal output port 211 is coupled to the signal receiving port 111 of the assembled product 100, so that a test instruction is sent to the signal receiving port 111 through the signal output port 211, thereby enabling the video main control chip 130 to start in response to the test instruction.

[0126] It should also be noted that, continue to refer to Figure 2 Before the storage module 125 outputs the prefabricated standard video, the detection method further includes: executing step S01, inputting a power signal adapted to the assembled product 100 to the assembled product 100.

[0127] A power signal is input to the assembled product 100 so that the assembled product 100 can be started.

[0128] Moreover, when the finished assembly 100 is working normally, the finished assembly 100 usually requires a specific power adapter (for example, a 12 volt, 1 ampere power adapter). The power adapter is a power source that has been verified to ensure that the finished assembly 100 can work normally. If the power signal is not compatible, it may cause large power ripple, thereby causing instability or system failure of the finished assembly 100.

[0129] Here, the power adapter refers to a power converter that outputs specific voltage and current values.

[0130] Therefore, when performing detection, a power signal that is compatible with the assembled product 100 is also used to reduce the probability of interference with the detection result due to incompatible power signal, thereby improving the reliability of the detection.

[0131] Moreover, the detection is performed based on a power signal that is compatible with the assembled product 100, so that the power signal used during the detection is consistent with the power signal used when it is put on the market for use, to ensure that the verified assembled product 100 can still work normally when it is put on the market for use.

[0132] Accordingly, combined with reference Figure 3 The finished assembly 100 has a power port 112. Before inputting a power signal matching the finished assembly 100 into the circuit board 110, the detection method further includes: coupling the finished assembly 100 and a power source 200 so as to input a power signal into the finished assembly 100 through the power source 200.

[0133] Specifically, Figure 3 As shown, the assembled product 100 has a power port 112 , and the power port 112 is coupled to a power source 200 .

[0134] Continue to refer Figure 2 , execute step S2, so that the video module 135 captures the preset standard video, and outputs the frame data to be tested of a specific frame based on the preset standard video, and the frame data to be tested and the standard frame data have the same frame sequence number in the preset standard video.

[0135] The video module 135 is enabled to capture the preset standard video and output the frame data to be tested of a specific frame, so that the quality of the video module 135 can be judged by comparing the frame data to be tested with the standard frame data.

[0136] In this embodiment, the video module 135 is provided by the video main control chip 130. The video main control chip 130 includes the video module 135, so that the assembled product 100 can realize the function of video playback through the video main control chip 130.

[0137] In this embodiment, the video module 135 is enabled to capture the preset standard video and output the frame data of a specific frame to be tested based on the preset standard video, including: controlling the video module 135 to capture the preset standard video and output the frame data of a specific frame to be tested based on the preset standard video through the video main control chip 130.

[0138] The video module 13 is controlled by the video main control chip 130 , so that under the control of the video main control chip 130 , the preset standard video is collected, and the frame data to be tested of a specific frame is output based on the preset standard video.

[0139] In this embodiment, the frame data to be tested output by the video module 135 based on the preset standard video has the same frame number as the standard frame data, so that the comparison between the frame data to be tested and the standard frame data is meaningful, so that it is possible to judge whether the quality of the video module 135 meets the requirements based on the comparison result.

[0140] In this embodiment, the standard frame data includes a standard frame image, and the frame data to be tested correspondingly includes a frame image to be tested, that is, the data types of the frame data to be tested and the standard frame data are the same, so they can be compared.

[0141] Correspondingly, the video module 130 includes a decoding unit (not shown), which is suitable for decoding the collected preset standard video and obtaining a frame image to be tested of a specific frame as the frame data to be tested.

[0142] It should be noted that when the storage module 125 stores preset standard videos of multiple formats, the decoding unit may include multiple decoding sub-units, and the decoding sub-units correspond to the format types one by one, so as to decode the preset standard videos of each format type.

[0143] Specifically, enabling the video module 130 to capture the preset standard video and output the frame data to be tested of the specific frame based on the preset standard video includes: enabling the decoding unit to decode the captured preset standard video and obtain the frame image to be tested of the specific frame as the frame data to be tested.

[0144] In this embodiment, the video module 130 outputs the frame data to be tested having the same frame number according to the frame number corresponding to the standard frame data.

[0145] Specifically, in the step of inputting a test instruction to the assembled product 100, the test instruction contains frame number information of the test frame data to be output according to the frame number of the standard frame data, which is used to control the decoding unit to output a specific frame image to be tested as the test frame data.

[0146] In this embodiment, the storage module 125 only stores the standard frame data of a specific frame in the preset standard video, and correspondingly, the video module 130 outputs the frame data to be tested of the specific frame.

[0147] Specifically, the specific frame is the first frame of the preset standard video.

[0148] It should be noted that the storage module 135 stores one or more types of preset standard videos and standard frame data of corresponding formats, and the format types of the preset standard videos are compatible with the video module. Therefore, the video module 135 outputs the frame data to be tested of the corresponding format type based on the data of the preset standard videos of each format type.

[0149] Correspondingly, the video main control chip 130 calls the data of the preset standard videos of various formats respectively, and obtains the frame data to be tested of the corresponding format through the video module 135 .

[0150] In the case where preset standard videos of multiple formats are stored in the storage module 135, the video module 135 outputs the frame data to be tested of the corresponding format type based on the data of the preset standard videos of each format type, so as to perform a comparison for each format type, and then detect whether the video module 135 can normally play videos of each format type.

[0151] Continue to refer Figure 2 , execute step S3, compare the frame data to be tested with the standard frame data having the same frame sequence number to obtain a comparison result.

[0152] The video module 135 is used to parse and process video data to output video images, and the standard frame data is frame data obtained based on a video module 135 of qualified quality. Therefore, by comparing, it is possible to verify whether the quality of the video module 135 meets the requirements.

[0153] The frame data to be tested with the same frame number is compared with the standard frame data, so that the comparison between the frame data to be tested and the standard frame data is meaningful, so that it can be judged whether the quality of the video module 135 meets the requirements according to the comparison result.

[0154] In this embodiment, the storage module 125 of the assembled product 100 stores data of a preset standard video and standard frame data corresponding to the preset standard video. The video module 135 collects the preset standard video output by the storage module 125, and outputs the frame data to be tested of a specific frame based on the preset standard video. The frame data to be tested and the standard frame data have the same frame sequence number in the preset standard video, so that in the assembly test process, the assembled product 100 can be used to compare the frame data to be tested with the standard frame data to achieve automatic detection of the video module 135. Compared with the manual detection solution, this is conducive to improving the detection reliability and detection efficiency of the video module 135; moreover, since the storage module 125 and the video module 135 have constituted the assembled product 100 during the detection, the quality of the video module 135 in the assembly test process can be detected, so that according to the test results, the assembled product 100 with abnormal video module 135 can be quickly and effectively intercepted in the assembly test process, thereby reducing the probability of abnormal assembled products 100 flowing into the market.

[0155] Moreover, the storage module 125 stores data of a preset standard video and standard frame data corresponding to the preset standard video. Therefore, when the assembled finished product 100 is inspected, each assembled finished product 100 can obtain an inspection result based on the same preset standard video and the same standard frame data, thereby improving the reliability of the inspection.

[0156] Because the storage module 125 has stored the data of the preset standard video and the standard frame data corresponding to the preset standard video before the inspection, when entering the inspection process, the inspection personnel do not need to write the preset standard video data and the standard frame data to each assembled finished product 100, nor do they need to call the standard video data and the standard frame data from outside the assembled finished product 100, thereby realizing automatic inspection of the assembled finished product 100 and improving the inspection efficiency.

[0157] Again, since the detection object of the detection method is the assembled finished product 100, a chip has been set on the circuit board 110, so the storage module 125 in the assembled finished product 100 can be used to store the data of the preset standard video and the standard frame data corresponding to the preset standard video.

[0158] In this embodiment, comparing the frame data to be tested with the standard frame data includes: enabling the video module 135 to output the frame data to be tested to the storage module 125; enabling the storage module 125 to compare the frame data to be tested with the standard frame data based on the preset comparison instruction.

[0159] By pre-storing instructions for comparing the frame data to be tested with the standard frame data in the storage module 125, the comparison function can be performed by the storage module 125 in the assembled product 100, and there is no need to set up an additional comparison module outside the assembled product 100, thereby further realizing automatic detection, improving detection efficiency, and reducing changes to the detection device.

[0160] In this embodiment, in the step of comparing the frame data to be tested with the standard frame data, the frame data to be tested and the standard frame data of the same format are compared respectively.

[0161] The frame data to be tested of the same format type is compared with the standard frame data, so that the comparison between the frame data to be tested and the standard frame data is meaningful, and then whether the video module 135 can normally play videos of various formats is detected.

[0162] Specifically, the storage module 125 is enabled to compare the frame data to be tested with the standard frame data of the same format type according to the preset comparison instruction.

[0163] In this embodiment, comparing the frame data to be tested with the standard frame data includes: performing image comparison between the standard frame image and the frame image to be tested.

[0164] Specifically, the standard frame image and the frame image to be tested are compared, including: performing a cyclic redundancy check (CRC) on the standard frame image to be compared and the frame image to be tested; judging whether the cyclic redundancy check results of the standard frame image and the frame image to be tested are the same; if so, judging that the comparison is successful, otherwise judging that the comparison fails.

[0165] If the comparison is successful, it means that the quality of the video module 135 is qualified, and if the comparison fails, it means that the quality of the video module 135 is unqualified.

[0166] It should be noted that, judging whether the cyclic redundancy check results of the standard frame image and the frame image to be tested are the same here means judging whether the cyclic redundancy check results are 100% the same.

[0167] It should be noted that the CRC check has a fast calculation speed, a strong error detection capability, and is easy to implement using hardware circuits such as encoders, thereby helping to improve the detection reliability and efficiency of the video module 135.

[0168] It is understandable that the comparison method is not limited to CRC. In other embodiments, other methods can also be used to compare, for example, parity check and other verification methods.

[0169] Continue to refer Figure 2 After comparing the frame data to be tested with the standard frame data, the detection method further includes: transmitting the comparison result to the display device 400 to display the comparison result.

[0170] By transmitting the comparison result to the display device 400, the comparison result is displayed to the inspector, so that the inspector can find abnormal assembled products 100, so that the assembled products 100 with abnormal video modules 135 can be quickly and effectively intercepted during the assembly test process.

[0171] Specifically, the test fixture 200 has a display interface 212, and the test fixture 200 is coupled to the display device 400 through the display interface 212. After comparing the frame data to be tested with the standard frame data, the comparison result is returned to the test fixture 200, and then transmitted to the display device 400 via the test fixture 200, so that the comparison result is displayed through the display device 400.

[0172] It should be noted that, in one embodiment, the detection method is used to detect the assembled finished product 100 of the above embodiment. In other embodiments, the detection method can also be used to detect other assembled finished products including circuit boards, video modules and storage modules.

[0173] Correspondingly, an embodiment of the present invention further provides a video device including the assembled product 100 of the aforementioned embodiment.

[0174] The quality of the finished assembly 100 can be quickly and effectively verified during the assembly test process to ensure that the finished assembly 100 with qualified quality is released to the market, so the video device has a higher quality.

[0175] As an example, the video device may be a set-top box (STB) or an over-the-top (OTT) box or a TV chip device. It should be noted that an OTT box refers to a high-definition terminal device that allows users to watch videos online via the Internet, i.e., an Internet set-top box.

[0176] In other embodiments, it may also be other video devices that have the function of playing videos.

[0177] Correspondingly, an embodiment of the present invention further provides an electronic device, which can implement the video module detection method provided by the embodiment of the present invention by loading the above-mentioned video module detection method in the form of a program.
