The byte number occupied by each screen parameter and the address of each screen parameter in the data structure are determined in the data structure. Optionally, in order to manage the screen parameters of the tv, all the screen parameters of the tv may be stored in the same data structure. In a specific embodiment, a data structure for storing screen parameters of a television may be set according to actual needs.

Optionally, in the C language, the offset of the parameter to be debugged in the preset storage area may be obtained by defining offset of a standard macro.
in step S303, after the module screen adjustment device obtains the offset of the parameter corresponding to the type of the parameter to be set in the data structure, the module screen adjustment device determines the storage address of the parameter in the preset storage area according to the offset. Optionally, when the preset storage area may be used only for storing the data structure, the offset of the parameter in the data structure is the start address of the storage address of the parameter in the preset storage area.
in the process, the screen parameters of the television are stored according to the preset data structure, so that the module screen debugging device can determine the storage address of the parameter to be debugged in the preset storage area according to the offset of the parameter to be debugged in the data structure, the efficiency of determining the storage address is improved, and the efficiency of processing the screen parameters is further improved.

Optionally, the user may modify the test values corresponding to the multiple parameters at the same time. After the user completes the parameter setting, the user may click on a determination button in the interface 603. And after the user clicks the determined button, the module screen debugging device generates a screen debugging instruction according to the modification of the user on the screen parameters. For example, assuming that the user has only modified the frame rate, a screen debug instruction is generated: set [ frame rate ] [24 ].
