For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] The invention aims at the existing problems and provides a set-top box self-test method.

[0045] like Figure 1 As shown, an embodiment of the present invention provides a set-top box self-test method, comprising:

[0046] The output data of the set-top box to be tested is received through the loop-back loop-out device, and the output data is processed to obtain test data;

[0047] The test data is identified in the set-top box to be tested to obtain identification information, and the self-test result of the set-top box to be tested is determined according to the identification information and the label information; wherein the label information corresponds to the identification information one by one.

[0048] In the embodiment of the present invention, the set-top box to be tested is equipped with a test application for testing the set-top box to be tested. The test application is used to identify test data, obtain identification information, and determine the self-test result of the set-top box to be tested according to the identification information and label information.

[0049] Since the set-top box has only an HDMI output interface and a USB input interface, in the embodiment of the present invention, the set-top box to be tested sends an HDMI signal to the loop-back loop-out device through the HDMI output interface when playing the original multimedia data. The HDMI signal includes the identification information of the set-top box to be tested and the original multimedia data processed by the set-top box to be tested; the loop-back loop-out device sends the processed multimedia data to the inside of the set-top box to be tested through the USB interface for testing. Figure 2 shown.

[0050] It should be noted that the loop-back loop-out device includes a processor, the input end of the processor is connected to the HDMI output interface of the set-top box to be tested, the output end of the processor is connected to the USB input port of the set-top box to be tested, the input end of the processor is used to receive the output data of the set-top box to be tested, the loop-back loop-out device also includes a frame processing module, which is used to encode the data input into the loop-back loop-out device, and can add identification information to the header of the encoded data for subsequent initialization verification of the set-top box, and the frame processing module can be a soft module or a hard module; when the frame processing module is a soft module, for ease of use, the module is mounted in the processor of the loop-back loop-out acquisition device, and when the frame processing module is a hard module, for ease of use, the input end of the module is connected to the HDMI output interface of the set-top box to be tested, and the output end of the module is connected to the input end of the processor in the loop-back loop-out acquisition device.

[0051] Specifically, the set-top box to be tested includes a unit to be tested, and before the set-top box to be tested outputs data, it also includes:

[0052] Adding label information to each piece of data in the original multimedia data to obtain labeled data;

[0053] Input the label data to the unit under test.

[0054] It should be noted that the tag information can be pre-set outside the set-top box to be tested or inside any unit in the set-top box to be tested, that is, the tag information can also be pre-stored in any storage unit inside the set-top box, and can even be stored outside the set-top box. It is only necessary to be able to read the tag information when the test unit performs a self-test. In order to facilitate fast reading, the embodiment of the present invention pre-sets the tag information in the unit to be tested. The tag information is used to mark each multimedia data in the original multimedia data. The original multimedia data can be video data, audio data, and picture data;

[0055] When the original multimedia data is video data, the tag information includes the number of frames, time point, resolution and QR code, and the tag information is added to the video data frame by frame in chronological order;

[0056] When the original multimedia data is audio data, the tag information is an audio file, and the audio file includes audio data of a sine wave, a pure high level, and a pure low level with volume levels of 0 dB, -20 dB, and 20 dB distributed at a fixed time;

[0057] When the original multimedia data is picture data, the tag information includes resolution, identification point, and QR code, and the tag information is added to each picture.

[0058] It should be noted that the frame number refers to the serial number added to each frame of video data, the time point includes the start time and the end time of the video data, the resolution refers to the resolution of each frame of video data or each picture, and the QR code is used to describe the basic information of the video data or the picture data, such as the sequence, the encoding information, etc.; due to the different levels of audio, the actual volume output through the interface is not necessarily the original volume of the audio, at this time it is necessary to find a system volume by adjusting the volume of the set-top box so that the volume output by the interface is consistent with the original volume. For this reason, in order to calibrate the test data, the embodiment of the present invention divides the volume into 0dB, -20dB, and 20dB. A pure high level means that the volume is always the maximum value per unit time, and a pure low level means that the volume is always the minimum value per unit time; an identification point refers to a feature on the picture data.

[0059] Specifically, the set-top box to be tested further includes a test unit, and output data of the set-top box to be tested includes the marking data processed by the test unit and identification information of the set-top box to be tested, the identification information represents the current characteristic information of the set-top box to be tested, and the output data is processed to obtain test data, including:

[0060] The received processed marking data is encoded by the loop-back loop-out device to obtain a plurality of test data, and the test data is transmitted back to the test unit of the set-top box to be tested.

[0061] It should be noted that, in the embodiment of the present invention, the encoding method adopted by the loop-back and loop-out device is a conventional video encoding method, an audio encoding method, or an image encoding method. For example, the video encoding method may be but is not limited to the MPEG4 video encoding method, the audio encoding method may be but is not limited to the pulse code modulation (PCM, Pulse Code Modulation) method, and the image encoding method may be but is not limited to the entropy coding method; the identification information represents the current characteristic information of the set-top box to be tested, such as the resolution, refresh rate, sound format, and number of channels of the current HDMI output screen of the set-top box to be tested, and can also represent the supplier information specific to the set-top box to be tested.

[0062] In the embodiment of the present invention, the test application program for testing the set-top box to be tested is installed in the test unit of the set-top box to be tested.

[0063] Specifically, before the test data is identified in the set-top box to be tested, it also includes:

[0064] The set-top box to be tested is initialized and verified according to the identification information of the set-top box to be tested.

[0065] Specifically, initialization verification is performed on the set-top box to be tested according to the identification information of the set-top box to be tested, including:

[0066] In the loop-back loop-out device, for each test data, identification information is added to the header of the test data to obtain multiple initialization verification data;

[0067] The control test unit reads each piece of initialization verification data and parses out the identification information in each piece of initialization verification data;

[0068] Comparing the parsed identification information with the initial characteristic information of the set-top box to be tested to obtain a first comparison result;

[0069] If the first comparison result is consistent, the set-top box to be tested passes the initialization verification; if the first comparison result is inconsistent, the set-top box to be tested is controlled to stop self-testing.

[0070] In an embodiment of the present invention, the initial feature information and the current feature information of the set-top box to be tested both include timing information Timing for generally referring to the output format, audio frame information Audio Info-Frame, and vendor-specific information vs-if that is specific to the set-top box to be tested, and the length of the identification information is fixed, which refers to the total length of the timing information, the audio frame information, and the vendor-specific information added together.

[0071] In an embodiment of the present invention, the self-test result of the set-top box to be tested can be determined by comparing the identification information with the label information on the corresponding marking data after identifying the test data through the identification model, or by comparing the identification information with the label information on the corresponding marking data and comparing the output time and the return time. The above two methods can also be superimposed to determine the self-test result of the set-top box to be tested. The comparison process of the two methods is described in detail below.

[0072] In the set-top box to be tested that has passed the initialization verification, the decoded test data is identified based on the AI ​​model to obtain identification information; and the test data is restored to the JPG format through decoding.

[0073] Specifically, the set-top box to be tested includes an AI model, which identifies the test data in the set-top box to obtain identification information, and obtains a self-test result of the set-top box to be tested based on the identification information and the label information, including:

[0074] Control the AI ​​model to identify the test data and obtain identification information;

[0075] Comparing the identification information with the label information on the corresponding marked data to obtain a second comparison result;

[0076] The self-test result of the set-top box to be tested is determined according to the second comparison result.

[0077] It should be noted that the AI ​​model can be pre-set in any unit in the set-top box to be tested. For ease of use, the embodiment of the present invention pre-sets the AI ​​model in the test unit to identify the test data; the AI ​​model is trained by labeled data. Since the test data used is the training set of the large model, the recognition accuracy of the AI ​​large model is theoretically close to 100%.

[0078] Most preferably, the recognition model is a TensorFlow model, which is an open source deep learning framework based on a data flow graph, and can be used to accurately identify the position and category of objects; it should be noted that the TensorFlow model is trained using conventional training methods, and the data used to train the TensorFlow model in the embodiment of the present invention is the same as the actual test data, both of which are output data of the set-top box to be tested.

[0079] In an embodiment of the present invention, when the test data is video data, the video data is identified by an AI model to obtain identification information, the identification information includes the frame number, time point, resolution and QR code of each frame of video data, and the identification information is compared with the label information on the corresponding marked data to obtain a second comparison result, which includes two situations, namely, consistency and inconsistency;

[0080] When the second comparison result is consistent, it is determined that the self-test result of the set-top box to be tested is that the played video data is displayed normally;

[0081] When the second comparison result is inconsistent, it is determined that the self-test result of the set-top box to be tested is that the played video data is displayed abnormally.

[0082] In an embodiment of the present invention, when the test data is audio data, the audio data is identified by an AI model to obtain identification information, wherein the identification information includes volume and change trend, wherein the volume is 0dB, -20dB, 20dB, and the change trend is a sine wave, a pure high level, and a pure low level;

[0083] In the same time period, the identification information is compared with the label information on the corresponding marked data to obtain a second comparison result, where the second comparison result includes two situations, namely, consistency and inconsistency;

[0084] When the second comparison result is consistent, determining that the self-test result of the set-top box to be tested is that the audio data is played normally;

[0085] When the second comparison result is inconsistent, determining that the self-test result of the set-top box to be tested is abnormal audio data playback;

[0086] Alternatively, in the same time period, the identification information is compared with the label information on the corresponding mark data to obtain the difference between the two. When the difference is not greater than a preset threshold, it is determined that the self-test result of the set-top box to be tested is that the audio data playback is normal; when the difference is greater than the preset threshold, it is determined that the self-test result of the set-top box to be tested is that the audio data playback is abnormal; the preset threshold can be set according to the scenario and needs.

[0087] In an embodiment of the present invention, when the test data is image data, the image data is identified by an AI model to obtain identification information, the identification information includes resolution, identification point, and QR code, and the identification information is compared with the label information on the corresponding mark data to obtain a second comparison result, which includes two situations, namely, consistency and inconsistency;

[0088] When the second comparison result is consistent, it is determined that the self-test result of the set-top box to be tested is that the played picture data is displayed normally;

[0089] When the second comparison result is inconsistent, it is determined that the self-test result of the set-top box to be tested is that the played picture data is displayed abnormally.

[0090] Specifically, the self-test result of the set-top box to be tested is determined according to the identification information and the label information, including:

[0091] Calculate the difference between the output time of each output data and the return time of the corresponding test data to the set-top box under test; wherein the output data corresponds to the test data one by one;

[0092] The delay mean is obtained based on the difference;

[0093] The self-test result of the set-top box to be tested is determined according to the second comparison result, the delay information of the test data and the delay mean.

[0094] In an embodiment of the present invention, when the set-top box to be tested outputs the output data, the output time of each output data is recorded, and the return time of each test data transmitted back to the set-top box to be tested is obtained. The output time and the return time of 300 frames of output data can be taken for difference calculation, and then the delay mean is calculated.

[0095] In order to improve the accuracy of the self-test, the embodiment of the present invention adopts the above two methods to be superimposed to determine the self-test result of the set-top box to be tested. Specifically, three different original multimedia data are used as examples to perform the self-test of the set-top box to be tested. The process is as follows:

[0096] When the original multimedia data is video data, the output time of the output data is recorded, and the output data is processed through a loop-back loop-out device to obtain test data and transmit it back to the test unit of the set-top box to be tested, and the return time of each test data to the set-top box to be tested is recorded; the test unit restores the test data to a video format and calls the trained AI model for recognition to obtain identification information, which may be one or more of the number of frames, resolution and QR code on each frame of video. By scanning the QR code, the basic information of each frame of video is obtained, and the identification information is compared with the label information on the corresponding marked data one by one. If the comparison is consistent, and the difference between the output time and the return time is within the preset difference range of the delay mean, then the self-test result of the set-top box to be tested is that the display of the frame of video data is normal, otherwise, the display of the frame of video data is abnormal.

[0097] When the original multimedia data is audio data, recording the output time of the output data;

[0098] The loop-back loop-out device encodes the received audio data through the frame processing module, obtains the encoded audio data and transmits it back to the test unit of the set-top box to be tested, and records the return time of the encoded audio data to the set-top box to be tested;

[0099] The test unit restores the encoded audio data to audio PCM format data through the restoration subunit, records the audio PCM format data with the help of the audio collector, and calculates the root mean square value of the audio PCM format data. The calculation expression is:

[0100]

[0101] The formula for converting audio PCM format data into decibels to represent volume is:

[0102] dB=20log 10 (RMS)

[0103] Among them, x i represents the i-th audio data, N represents the total number of audio data, dB represents decibel, and RMS represents the root mean square value of audio PCM format data;

[0104] The root mean square value of the audio PCM format data is converted into decibels to represent the volume, and the AI ​​model is used to identify it to obtain identification information, which includes the volume and the change trend. The volume is 0dB, -20dB, and 20dB, and the change trend is sine wave, pure high level, and pure low level.

[0105] In the same time period, the identification information is compared with the label information on the corresponding marked data to obtain a second comparison result;

[0106] When the second comparison result is consistent, and the difference between the output time and the return time is within the preset difference range of the delay mean, the self-test result of the set-top box to be tested is determined to be normal audio data playback; otherwise, the self-test result of the set-top box to be tested is determined to be abnormal audio data playback.

[0107] When the original multimedia data is picture data, the output time of the output data is recorded;

[0108] The loop-back loop-out device encodes the image data through the frame processing module, transmits the encoded image data back to the test unit in the set-top box to be tested, and records the transmission time of the encoded image data back to the set-top box to be tested;

[0109] The processed image data is restored to the image format and input into the trained recognition model for recognition to obtain recognition information. The recognition information can be one or more of resolution, recognition point and QR code. These recognition information are compared with the label information on the corresponding marked data one by one. If the information is consistent and the difference between the output time and the return time is within the preset difference range of the delay mean, the self-test result of the set-top box to be tested is that the image data is displayed normally. Otherwise, the image data is displayed abnormally.

[0110] It should be noted that if the three test data, namely, video data, audio playback, and picture data, are all displayed or played normally, the self-test result of the set-top box under test is that the set-top box under test is qualified; if any one of the three test data, namely, video data, audio playback, and picture data, is displayed or played abnormally, the self-test result of the set-top box under test is that the set-top box under test is unqualified, thereby improving the accuracy of the set-top box self-test.

[0111] The embodiment of the present invention receives output data of a set-top box to be tested through a loop-back loop-out device, and processes the output data to obtain test data; the test data is identified in the set-top box to be tested to obtain identification information, and the self-test result of the set-top box to be tested is determined according to the identification information and label information; wherein the label information corresponds one to one with the identification information; compared with the prior art, the present invention only utilizes two devices, the loop-back loop-out device and the set-top box to be tested, thereby reducing the number of test devices, and directly identifies the test data in the set-top box to be tested to obtain identification information, and determines the self-test result of the set-top box to be tested according to the identification information and label information. The test result is obtained inside the set-top box to be tested, which can effectively prevent the accuracy problem caused by the self-consumption of the external device, thereby improving the accuracy of the test, and further identifies the identification information through an artificial intelligence algorithm for testing, thereby solving the problem that the traditional testing method relies more on manual labor and is prone to missed tests or some test loopholes that are difficult for manual labor to detect.

[0112] like Figure 3 As shown, the embodiment of the present invention further provides a set-top box self-test device 100, and the set-top box self-test device 100 includes:

[0113] The processing module 101 is used to receive the output data of the set-top box to be tested through the loop-back loop-out device, and process the output data to obtain test data;

[0114] The test module 102 is used to identify the test data in the set-top box to be tested, obtain identification information, and determine the self-test result of the set-top box to be tested according to the identification information and the label information; wherein the label information corresponds to the identification information one by one.
