Description
Technical Field

Background
When the display testing equipment is used for testing the performance of the display, the image signal needs to be sent to the display first, and then the parameter information of the image on the display is tested. An image signal generating module is integrated in the testing equipment, and the generated image signal is packaged based on a certain communication protocol and then output through an output interface corresponding to the communication protocol.
The image signal input interface of the finished display is often fixed, and the types of the signal input interfaces of displays of different models are not consistent. For example, the signal input interface of the type a display is a DP interface, and the signal input interface of the type B display is an HDMI interface. When testing devices with different interfaces are required to be tested, the testing device with a single type of output interface cannot transmit signals to the display, for example, if the output interface of the testing device is DP, the same device can only test device a, but cannot test device B. In order to solve the problem, people usually set a plurality of output interfaces of different types on the testing device to achieve the purpose of testing the variety of the display.
However, the type, number, and setting sequence of the output interfaces on the test equipment are all fixed, and when the existing output interfaces on the test equipment cannot be matched with the interface of the display to be tested, the test process cannot be performed. For example, the current test equipment has DP and HDMI interfaces, and if the interface model of the display to be tested is VGA, the output port of the equipment needs to be replaced to match the VGA interface. Generally, the replacement of the type of the output port needs to change the bottom code of the equipment, so that the difficulty is great; on the other hand, changing the output port type also increases the operational requirements on the device, and also increases the test cost of the display.

The following detailed description of embodiments of the present application will be described in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Referring to fig. 1, the present application provides an image signal transmission method, and the present embodiment is described by taking an example of applying the image signal transmission method to a display device test apparatus. The display device test equipment is internally provided with a control component, and the execution main body of each step of the image signal transmission method is the control component.

The method comprises the following steps:
Further, in step 110, obtaining the current port type and location of each output port includes:
and acquiring a level value of each output port, and confirming the current port type of each output port according to the level value. Specifically, the level value has a corresponding relationship with a port type, for example, when the level value of the a port is 1101, the port type is a DP port; when the a port type is 1100, the port type is an HDMI port. The obtaining of the port level value is performed in the prior art, and this embodiment will not be described in detail, and those skilled in the art can understand and implement the obtaining of the port level value.
Wherein, in step 110, the method further comprises the following steps:
and confirming the position of the target output port according to the type and the position of each current port and the type of the target output port.
And the position of the output port corresponding to the current port type which is the same as the type of the target output port is the position of the target output port.
Optionally, if more than 1 current port type of the plurality of current port types is consistent with the target output port type, all ports with the current port type consistent with the target output port type are defined as the target output ports. For example, the port 1, the port 2, and the port 3 are all DP ports, and if the target output port type is a DP port, the port 1, the port 2, and the port 3 are all target output ports.
In this step, the port type and the position of each output port are acquired, and the distribution condition of the output ports in the current state can be acquired after the output ports are replaced, so that the specific position of the target output port is confirmed according to the current port setting condition, and the image signal can be accurately transmitted to the target output port.

And when the type of the target output port is not consistent with any current port type, sending out a port replacement warning. The step can judge whether the user needs to be reminded to replace the port according to the setting state of the output port, thereby avoiding the transmission failure of the image signal caused by the setting error of the port.
Optionally, the port replacement warning may be performed in various manners such as transmitting a signal to an interface of a human-computer interaction control terminal, and giving a sound prompt, and a person skilled in the art may select any scheme capable of implementing a warning function according to an actual situation.

In this embodiment, an example is made, and when the detection device is shipped from a factory, the first communication protocol is preset to be a DP protocol.
Wherein, this step still includes: and confirming the target communication protocol corresponding to the target output port type according to the target output port type. Further, the communication protocol and the output port type are in a corresponding relationship, for example, if the target output port type is a DP port, the target communication protocol is a DP protocol.
Specifically, in this step, the judgment result obtained is "yes", or "no".
Optionally, the determining process is: and obtaining a judgment result by judging whether the level values of different ports are consistent.
when the first communication protocol is different from the target communication protocol, that is, the structure is judged to be 'no', the first communication protocol of the packet data stream is converted into the target communication protocol and then output from the target output port.
When a signal is output, if more than 1 port type in the current port types is consistent with the target output port type, that is, there are more than 1 target output ports, the data stream is output from all the target output ports.
In step, the communication protocol is converted into the prior art, such as the prior art communication protocol conversion card: after a plurality of communication interfaces receive and forward data to the MCU, the MCU analyzes and converts the data respectively, the communication with the equipment is realized through the CPLD and the hardware interface, and the simultaneous transmission and exchange of two or more communication protocols can be realized through one communication protocol conversion card. The specific scheme of how to implement the communication protocol conversion is not described in detail in this embodiment.
The image signal transmission method is applied to display device testing equipment and used for testing the performance of the display device. Preferably, in order to complete the performance test of the display device, the following test parameter setting step may be further included before step 110:
and acquiring the types of the parameters to be detected, such as picture Timing, color depth, picture labels and the like.
