Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments.

Based on this, embodiments of the present application provide a method, an apparatus, a terminal and a computer readable storage medium for testing a CEC circuit of an HDMI interface, which can automatically perform a CEC circuit test of the HDMI interface, and improve the CEC circuit test efficiency of the HDMI interface.

In order to explain the technical means of the present application, the following description will be given by way of specific examples.

When the CEC circuit of the HDMI interface provided on the main board to be tested is tested, as shown in fig. 1, the main board to be tested is connected to the CEC device supporting the CEC function through the HDMI interface. At this time, the CEC circuit of the HDMI interface on the motherboard to be tested can be tested by using the CEC circuit testing method of the HDMI interface provided by the present application.

It should be noted that, as shown in fig. 2, the CEC device supporting the CEC function connected to the main board to be tested may be provided by a signal source, and when the CEC circuit of the HDMI interface disposed on the main board to be tested is tested, the main board to be tested may be connected to one or more CEC devices supporting the CEC function in the signal source through the HDMI interface. At this time, the CEC circuit of the HDMI interface on the motherboard to be tested can also be tested by using the CEC circuit testing method of the HDMI interface provided by the present application.

Fig. 3 is a schematic diagram illustrating an implementation flow of a CEC circuit testing method for an HDMI interface according to an embodiment of the present application, where the method is applicable to a terminal, and can be executed by a CEC circuit testing device of an HDMI interface configured on the terminal, and is suitable for a situation where a CEC circuit test of the HDMI interface needs to be performed automatically, so as to improve CEC circuit testing efficiency of the HDMI interface. The terminal can be an intelligent terminal such as a smart phone, a computer and a smart television.

The CEC circuit test method of the HDMI interface described above may includesteps 301 to 302.

Step 301, acquiring the number of CEC devices connected to the main board to be tested through the main board to be tested.

In the embodiment of the application, because when the CEC circuit of the HDMI interface is tested, all CEC functions and indexes of the HDMI interface do not need to be tested, only it needs to be determined whether the CEC circuit of the HDMI interface arranged on the main board to be tested can realize communication between the main board to be tested and the CEC device, i.e., it is determined whether the CEC circuit of the HDMI interface arranged on the main board to be tested can normally work, therefore, the number of the CEC devices connected with the main board to be tested can be obtained through the main board to be tested, and the number is compared with the number of the CEC devices actually connected with the main board to be tested, thereby completing the test of the CEC circuit of the HDMI interface.

Specifically, as shown in fig. 4, in some embodiments of the present application, the obtaining, by the motherboard to be tested, the number of CEC devices connected to the motherboard to be tested may include:step 401 tostep 402.

Step 401, sending a CEC broadcast message to the CEC device connected to the motherboard to be tested through the motherboard to be tested, and receiving, by the motherboard to be tested, CEC device information sent by the CEC device according to the received CEC broadcast message.

And 402, acquiring the number of CEC devices connected with the mainboard to be tested, which are acquired by the mainboard to be tested according to the CEC device information.

That is, the motherboard to be tested may send a CEC broadcast message to the CEC device connected to the motherboard to be tested; after receiving the CEC broadcast message sent by the motherboard to be tested, the CEC device may feed back CEC device information to the motherboard to be tested; after the main board to be tested receives the CEC device information fed back by the CEC device, the number of CEC devices connected to the main board to be tested can be obtained according to the CEC device information. At this time, the terminal may directly obtain the number of CEC devices connected to the main board to be tested, which is obtained by the main board to be tested.

It should be noted that, if the CEC circuit of the HDMI interface on the main board to be tested is normal, the main board to be tested may receive CEC device information sent by all CEC devices connected to the main board to be tested; if the CEC circuit of any HDMI interface on the mainboard to be tested is abnormal, the mainboard to be tested cannot receive the CEC equipment information sent by all the CEC equipment connected with the mainboard to be tested.

For example, 3 HDMI interfaces on the tv PCB main board all support CEC functions, the 3 HDMI interfaces are respectively connected to 3 CEC devices that support CEC functions, the tv PCB main board can send a CEC broadcast message to the CEC device connected to the tv PCB main board, if the CEC circuits of the 3 HDMI interfaces are all normal, the CEC device information fed back by the CEC device received by the tv PCB main board will be equal to 3, and if the CEC circuit of any HDMI interface in the 3 HDMI interfaces is abnormal, the CEC device information received by the tv PCB main board will be less than 3.

In some embodiments of the present application, the main board to be tested may include a CEC device list, and after the main board to be tested receives CEC device information sent by a CEC device connected to the main board to be tested, the main board to be tested may automatically accumulate, according to the CEC device information, the number of CEC devices connected to the main board to be tested in the CEC device list; at this time, the terminal may directly obtain the number of CEC devices connected to the main board to be tested through the CEC device list.

Step 302, comparing the number of the CEC devices connected to the main board to be tested, which are acquired by the main board to be tested, with the preset CEC device number, and obtaining a test result whether the CEC circuit of the HDMI interface is normal or not according to the comparison result.

The preset CEC equipment number is the number of CEC equipment actually connected with the mainboard to be tested.

In some embodiments of the present application, the preset CEC device number may be obtained before comparing the number of CEC devices connected to the main board to be tested, which is obtained by the main board to be tested, with the preset CEC device number. For example, a manually input preset number of CEC devices may be acquired.

It should be noted that, in actual operation, the number of CEC devices actually connected to the motherboard to be tested may be equal to the maximum number of CEC devices that can be supported by the motherboard to be tested; at this time, by using the method for testing the CEC circuit of the HDMI interface provided by the present application, the test of the CEC circuits of all HDMI interfaces supporting the CEC function on the main board to be tested can be completed.

Specifically, after acquiring the number of CEC devices connected to the main board to be tested through the main board to be tested and acquiring the preset number of CEC devices, the above-mentioned test result of whether the CEC circuit of the HDMI interface is normal according to the comparison result may include: if the number of the CEC devices connected with the mainboard to be tested, which is acquired by the mainboard to be tested, is the same as the preset number of the CEC devices, the CEC circuit of the HDMI interface is confirmed to be normal; and if the number of the CEC devices connected with the mainboard to be tested, which is acquired by the mainboard to be tested, is different from the preset CEC device number, determining that the CEC circuit of the HDMI interface is abnormal.

In practical application, the same HDMI interface may be simultaneously connected to a plurality of CEC devices supporting CEC functions, and similarly, if the number of CEC devices connected to the main board to be tested, which is acquired by the main board to be tested, is the same as the preset number of CEC devices, it may be determined that the CEC circuit of the HDMI interface is normal; if the number of the CEC devices connected with the mainboard to be tested, which is acquired by the mainboard to be tested, is different from the preset CEC device number, the abnormality of the CEC circuit of the HDMI interface can be confirmed.

For example, 3 HDMI interfaces on the main board of the tv PCB support CEC functions, wherein 2 HDMI interfaces are respectively connected to 2 CEC devices supporting CEC functions, and 1 HDMI interface is simultaneously connected to 2 CEC devices supporting CEC functions. At this time, the television PCB main board sends a CEC broadcast message to the CEC device connected to the television PCB main board, and if the CEC device information fed back by the CEC device received by the television PCB main board is equal to 4, it can be confirmed that the CEC circuits of the 3-way HDMI interface are normal; if the number of the CEC device information received by the main board of the television PCB is less than 4, it can be confirmed that there is an abnormality in the CEC circuit of one or more HDMI interfaces among the 3 HDMI interfaces.

In order to further improve the efficiency of the CEC circuit test of the HDMI interface, in some embodiments of the present application, the sending the CEC broadcast message to the CEC device connected to the motherboard to be tested through the motherboard to be tested may include: and automatically sending the CEC broadcast message to CEC equipment connected with the mainboard to be tested when the mainboard to be tested is powered on.

For example, the main board to be tested is set, so that when the main board to be tested is powered on, a CEC broadcast message can be automatically sent to CEC devices connected with the main board to be tested, and after CEC device information sent by the CEC devices connected with the main board to be tested is received, the number of the CEC devices connected with the main board to be tested in a CEC device list is automatically accumulated according to the CEC device information; when the terminal tests the CEC circuit of the HDMI, the number of CEC devices connected with the mainboard to be tested can be directly obtained through the CEC device list, the number of CEC devices connected with the mainboard to be tested does not need to be obtained by waiting for the mainboard to be tested, and therefore the efficiency of CEC circuit testing of the HDMI is improved.

In practical applications, a part of the main boards to be tested cannot automatically send a CEC broadcast message to the CEC device connected to the main board to be tested when being powered on, and in order to improve the universality of the CEC circuit testing method of the HDMI interface, in some other embodiments of the present application, the sending of the CEC broadcast message to the CEC device connected to the main board to be tested by using the main board to be tested may include: and sending a CEC equipment number obtaining instruction to the mainboard to be tested, and sending a CEC broadcast message to the CEC equipment connected with the mainboard to be tested by the mainboard to be tested according to the received CEC equipment number obtaining instruction.

That is to say, the main board to be tested may send, after receiving the CEC device number acquisition instruction sent by the terminal, a CEC broadcast message to the CEC devices connected to the main board to be tested according to the received CEC device number acquisition instruction, receive CEC device information sent by the CEC devices according to the received CEC broadcast message, and obtain, according to the CEC device information, the number of the CEC devices connected to the main board to be tested.

In some embodiments of the present application, in order to facilitate a worker to check and maintain a test result of a CEC circuit of an HDMI, after obtaining a test result of whether the CEC circuit of the HDMI is normal according to a comparison result, the method may include: and uploading the test result of whether the CEC circuit of the HDMI interface is normal to the server.

The server may be a local server or a cloud server, which is not limited in this application.
