[0002] The HDMI interface is a high-definition multimedia interface that can transmit high-quality video and audio signals. The HDMI interface is suitable for a variety of electronic devices such as high-definition televisions and computer monitors, providing clear and sharp images and rich audio experience. With the popularity of the HDMI interface and the rich functions of electronic devices, some devices even have multiple HDMI interfaces. In the process of electronic equipment research and development and production, it is a necessary step to detect whether the functions of each HDMI interface on the electronic equipment are normal before the electronic equipment leaves the factory.

[0003] In the prior art, in order to save manpower and equipment, when testing the HDMI interface function, an HDMI splicer is often used to display the contents of multiple HDMI interfaces on one screen, and then the contents of each HDMI interface are manually observed to see if they can be displayed normally. When encountering display abnormalities, it is necessary to manually record the HDMI port with the abnormal display and notify the R&D personnel to confirm the problem on site; after the abnormality is improved, it is necessary to retest to confirm whether the problem has been solved. Therefore, in the prior art, the HDMI interface test efficiency is low and it is easy to make mistakes due to human factors. Summary of the invention

[0012] Furthermore, before the test device controls the device under test to power on periodically within a preset time threshold through the relay control device, the test device further includes the following steps:

[0013] Presetting the first test mode and the second test mode, and presetting the time threshold on the test device;

[0014] The device under test is set to enter a test state, so that the device under test can automatically control each HDMI interface to output the output signal after being powered on.

[0018] The relay control device is connected to the test device control and connects the device under test to a power source; the test device is connected to an HDMI interface of the device under test;

[0019] The test device is used to control the device under test to power on periodically within a preset time threshold through a relay control device, and monitor whether the output signal of the HDMI interface of the device under test meets the standard; and when the output signal does not meet the standard, control the relay control device to continuously supply power to the device under test according to a preselected first test mode to keep the output signal in a current fault state, or record the current fault state of the output signal according to a preselected second test mode, and repeatedly test the HDMI interface within the time threshold and count the test results.

[0020] Furthermore, the test device is provided with more than two test interfaces, and the more than two test interfaces are respectively connected to the more than two HDMI interfaces on the device under test and perform testing.

[0044] See also Figure 1 , this embodiment provides a HDMI interface testing method. The HDMI interface testing method can be applied to test various electronic devices with HDMI interfaces to confirm whether the functions of their HDMI interfaces are normal. The electronic devices with HDMI interfaces include any one of televisions, set-top boxes, projectors, computer monitors, game devices, audio systems, etc. In the related art, the HDMI interfaces of electronic devices are mainly tested manually, so there are problems such as low test efficiency and easy missed detection. Based on these problems, the present application proposes a HDMI interface testing method, which has multiple test modes, and can automatically test the functions of the HDMI interface according to different test modes, thereby improving the test efficiency, and at the same time can also reduce the problems of missed detection caused by manual detection, thereby improving the test accuracy.

[0045] like Figure 1 As shown, in this embodiment, the HDMI interface testing method includes the following steps:

[0046] S101, the test device controls the device under test to power on periodically within a preset time threshold through a relay control device;

[0047] S102, monitoring whether the output signal of the HDMI interface of the device under test meets the standard;

[0048] S103, if the standard is met, the output HDMI interface functions normally;

[0049] If the output signal does not meet the standard, the process jumps to step S104 and performs a test according to the first test mode; or jumps to step S105 and performs a test according to the second test mode.

[0050] In step S104, the relay control device is controlled to continuously supply power to the device under test according to a preselected first test mode so that the output signal remains in a current fault state; in step S105, the current fault state of the output signal is recorded according to a preselected second test mode, and the HDMI interface is repeatedly tested within the time threshold and the test results are counted.

[0051] In step S101, the test device refers to a main control device for performing the HDMI interface test method, which is provided with a test program and can test the function of the HDMI interface of the device under test through the cooperation of the relay control device. The test device can be an electronic device with digital signal processing, input and output capabilities, for example, the test device can be a PC, a tablet computer, etc. The relay control device has actuators such as electric control switches, which can control the operating state of the controlled device according to a preset cycle or according to a received control signal, for example, it can control the connection or disconnection of the controlled device with the power supply, or control the connection or disconnection of the output of the controlled device with the load. Figure 2 As shown, it is a circuit connection diagram of the HDMI interface test device in this embodiment. In this embodiment, the relay control device 20 is used to control the power on or off of the device under test 30. The input end of the relay control device 20 is connected to the power supply. When the electric control switch in the relay control device 20 is turned on, the device under test 30 is controlled to be connected to the power supply, so that the device under test 30 is powered on; when the electric control switch in the relay control device 20 is disconnected, the device under test is powered off. Among them, the relay control device 20 is connected to the test device 10, the relay control device 20 is controlled by the test device 10, and controls the power on or off of the device under test according to the control signal of the test device 10. Among them, the relay control device 20 includes any one of a USB relay control device, a serial port relay control device, and a wireless relay control device, and the relay control device is connected to any one of the USB interface, serial port or wireless communication module of the test device. The wireless relay control device includes a Bluetooth relay control device, a WIFI relay control device, a 4G / 5G relay control device, and the like.

[0052] Before the step S101, in which the test device controls the device under test to power on periodically within a preset time threshold through the relay control device, the step further includes:

[0053] The first test mode and the second test mode are preset on the test device, and the time threshold is preset; the device under test is set to enter a test state so that the device under test can automatically control each HDMI interface to output the output signal after power-on.

[0054] In step S101, the time threshold and the number of cycles of periodic power-on can be set accordingly according to the actual test requirements, and the present application does not specifically limit this. For example, if the test requires 100 cycles of testing the HDMI interface, and each test takes 1 minute, the preset time threshold should be greater than or equal to 100 minutes. And in step S101, each time the device under test is powered on, its HDMI interface outputs the output signal to the outside, so by periodically powering on the device under test, the HDMI interface of the device under test can be tested repeatedly for multiple times.

[0055] The HDMI interface of the device under test is connected to the test device through an HDMI data cable. When the device under test is powered on and enters the test mode, the HDMI interface will output a preset HDMI signal (i.e., a high-definition video signal) in the test mode. In step S102, the test device detects the received HDMI signal to determine whether the function of the HDMI interface is normal; if the output signal meets the standard, it means that the function of the HDMI interface is normal, otherwise it is abnormal. Among them, the monitoring of whether the output signal of the HDMI interface of the device under test meets the standard includes: determining whether the output signal is received, and comparing the resolution and content of the received output signal with the pre-stored standard parameters; if the output signal is not received, or the resolution and content do not match the standard parameters, it is determined that the output signal of the HDMI interface does not meet the standard. In step S102, the specific standard for whether the output signal meets the standard can be set according to the actual situation, such as whether the clarity of the output signal of the HDMI interface received by the test device reaches 4K.

[0056] In this embodiment, the relay control device is a USB relay control device, such as Figure 2 As shown, the test device is connected to the relay control device via a USB interface, and the device under test may be provided with multiple HDMI interfaces, each of which is connected to the test device. The test device sends a control command to the relay control device via the USB interface, thereby controlling the device under test to power on and off multiple times, and a control process is provided in the test device to automatically test the HDMI interface of the device under test when it is powered on and off multiple times.

[0057] When testing, the test equipment reads the resolution and picture of the output signal of the tested device through the HDMI interface, and compares it with the preset standard parameters to confirm whether the function of the HDMI interface of the tested device is normal. If the test equipment cannot detect that the resolution of the HDMI interface input is valid and the input content is correct within the test time threshold, the HDMI interface of the tested device is considered abnormal. After confirming that the function of the HDMI interface is abnormal (i.e., the display is abnormal), when the test equipment is in the first test mode, the first test mode is the error pause mode, then the test equipment controls the test operation to pause and enter the waiting state, that is, maintain the current state to wait for the R&D personnel to confirm the problem site and retest. When the test equipment is in the second test mode, the second test mode is the statistical error mode, then the test equipment records the current error and sends a power-off command to the relay control device until the number of test cycles is reached.

[0058] In this embodiment, the HDMI interface testing method can automatically test the function of the HDMI interface, and when a functional abnormality of the HDMI interface is detected, the problem can be paused or recorded and then the probability of occurrence can be continued to be tested, thereby realizing automatic reproduction of the problem without the need for manual operation, and improving the efficiency and accuracy of the HDMI interface test.

[0059] like Figure 2 As shown, in this embodiment, the device under test includes more than two HDMI interfaces; the test device is connected to the more than two HDMI interfaces respectively, and tests the more than two HDMI interfaces at the same time according to the preselected first test mode or the second test mode.

[0060] In normal use, each HDMI interface of the device under test can be used separately, and each HDMI interface can output the same video signal or output different video signals respectively. When performing HDMI interface testing, each HDMI interface can output the same output signal mentioned above, so that multiple HDMI interfaces can be tested at the same time to improve test efficiency. In some embodiments, different HDMI interfaces can also output output signals with different parameters to achieve differential testing of different HDMI interfaces. For example, HDMI interface 1 outputs 8K video signals, and HDMI interface 2 inputs 4K video signals.

[0061] Of course, the HDMI interface testing method of the present application is not limited to the testing of multiple HDMI interfaces, and is also applicable to a device under test with a single HDMI interface.

[0062] See also Figure 3In another embodiment, a HDMI interface test device 300 is provided. The HDMI interface test device 300 is used to test the HDMI interface of a device under test, and the HDMI interface test device 300 includes: a test device 10 and a relay control device 20.

[0063] The relay control device 20 is connected to the test device and connects the device under test to a power source; the test device is connected to the HDMI interface of the device under test. The test device 10 is used to control the device under test to periodically power on within a preset time threshold through the relay control device 20, and monitor whether the output signal of the HDMI interface of the device under test meets the standard; and when the output signal does not meet the standard, control the relay control device to continuously supply power to the device under test according to a preselected first test mode, so that the output signal remains in the current fault state, or record the current fault state of the output signal according to a preselected second test mode, and repeatedly test the HDMI interface within the time threshold and count the test results.

[0064] Wherein, if the output signal meets the standard, it means that the function of the HDMI interface is normal, otherwise it is abnormal. Wherein, the monitoring of whether the output signal of the HDMI interface of the device under test meets the standard includes: determining whether the output signal is received, and comparing the resolution and content of the received output signal with the pre-stored standard parameters; if the output signal is not received, or the resolution and content do not meet the standard parameters, then it is determined that the output signal of the HDMI interface does not meet the standard. The specific standard for whether the output signal meets the standard can be set according to the actual situation, such as whether the clarity of the output signal of the HDMI interface received by the test device reaches 4K.

[0065] In this embodiment, the connection method between the HDMI interface testing device 300 and the device under test is the same as the HDMI interface testing method in the above embodiment, both of which adopt Figure 2 The connection method shown in the figure will not be repeated here.

[0066] The test device refers to a main control device for performing the HDMI interface test method, which is provided with a test program, and the function of the HDMI interface of the device under test can be tested through the cooperation of the relay control device. The test device can be an electronic device with digital signal processing, input and output capabilities, for example, the test device can be a PC, a tablet computer, etc. The relay control device has an actuator such as an electric control switch, which can control the operating state of the controlled device according to a preset cycle or according to a received control signal, for example, it can control the controlled device to be connected or disconnected with a power supply, or control the output of the controlled device to be connected or disconnected with a load. The relay control device 20 includes any one of a USB relay control device, a serial port relay control device, and a wireless relay control device, and the relay control device is connected to any one of the USB interface, serial port or wireless communication module of the test device. The wireless relay control device includes a Bluetooth relay control device, a WIFI relay control device, a 4G / 5G relay control device, and the like. Each time the device under test is powered on, its HDMI interface outputs the output signal to the outside, so by periodically powering on the device under test, the HDMI interface of the device under test can be repeatedly tested multiple times.

[0067] In this embodiment, if the test device cannot detect that the resolution of the HDMI interface input is valid and the input content is correct within the test time threshold, the HDMI interface of the tested device is considered to be abnormal. After confirming that the function of the HDMI interface is abnormal (i.e., the display is abnormal), when the test device is in the first test mode, the first test mode is an error pause mode, then the test device controls the test operation to pause and enters the waiting state, that is, maintains the current state to wait for the R&D personnel to confirm the problem site and retest. When the test device is in the second test mode, the second test mode is a statistical error mode, then the test device records the current error and sends a power-off command to the relay control device until the number of test cycles is reached. Therefore, the HDMI interface test device can automatically test the function of the HDMI interface, and when the function of the HDMI interface is detected to be abnormal, it can pause or record the problem and continue to test the probability of occurrence, realizing the automatic reproduction of the problem, without manual operation, and improving the efficiency and accuracy of the HDMI interface test.

[0068] like Figure 2 As shown, in this embodiment, the test device is provided with more than two test interfaces, and the more than two test interfaces are respectively connected to the more than two HDMI interfaces on the device under test and perform testing.

[0069] When testing the HDMI interface, each HDMI interface can output the same output signal, so that multiple HDMI interfaces can be tested at the same time to improve the test efficiency. In some embodiments, different HDMI interfaces can also output output signals with different parameters to achieve differential testing of different HDMI interfaces. For example, HDMI interface 1 outputs 8K video signals, and HDMI interface 2 inputs 4K video signals.

[0070] like Figure 4 As shown, in one embodiment, a computer-readable storage medium 400 is provided, in which a computer program is stored. When the computer program is executed by a processor, the HDMI interface test method described in the above embodiment is executed.

[0071] The computer-readable storage medium may be a volatile memory or a non-volatile memory, or may include both volatile and non-volatile memories. The non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a ferromagnetic random access memory (FRAM), a flash memory, a magnetic surface memory, an optical disk, or a compact disc read-only memory (CD-ROM); the magnetic surface memory may be a disk memory or a tape memory.

[0072] The volatile memory may be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of RAM are available, such as static random access memory (SR AM), synchronous static random access memory (SSR AM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link dynamic random access memory (SLDRAM), direct memory bus random access memory (DRRAM). The computer-readable storage medium described in the embodiments of the present invention is intended to include these and any other suitable types of memory.

[0073] In some embodiments, the processor may be implemented by software, hardware, firmware or a combination thereof, and may use at least one of a circuit, a single or multiple application specific integrated circuits (ASIC), a digital signal processor (DSP), a digital signal processing device (DSPD), a programmable logic device (PLD), a field programmable gate array (FPGA), a central processing unit (CPU), a controller, a microcontroller, and a microprocessor, so that the processor may execute some or all of the steps in the HDMI interface test method in each embodiment of the present application or any combination of the steps therein.
