Description

How to handle options in a subfunction module {METHODS FOR OPTION MANAGEMENT OF SUB FUNCTION MODULE}

The present invention relates to an option processing method of a sub function module, and more particularly, when a sub function module is inserted into a television and monitor related product, a main function module The present invention relates to an option processing method of a sub function module which can automatically execute an option provided by an inserted sub function module by recognizing this.

In general, television or monitor-related products are produced and supplied by model when a manufacturing company produces them, and sub-function modules in which sub-programs for additional functions are stored in addition to the main function module having a main program for the unique functions of the model. You can optionally insert.

The sub-function module supplied to the model includes a sub program that receives the functions provided by the sub-function module, and an on-screen display (OSD), which displays the functions of the sub-function module. The program is saved. Even if such a sub function module is inserted into the model, the main function module of the model, i.e., the microprocessor, does not recognize it. Therefore, in the factory mode, the factory processes the option processing derived from the model by applying a password in the factory mode. Processes the options of the subfunction module inserted in the module, ie the specification.

That is, when the sub function module is inserted into the corresponding model, the manufacturer's production line turns on the model and checks whether the operation of the constant voltage terminal (Vcc) is normal. Check if the control is working properly.

When the system is normally operated, it enters the factory mode to control the operation state of the OSD, and in the factory mode, the inserted sub function module is optionally designed. When the option design of the sub function module is completed in the factory mode, the factory mode is terminated. When the factory mode is finished, the option designed according to the sub function module inserted in the model is executed in the factory mode to display the function of the sub function module. OSD character is displayed and exits when the function of OSD is operated normally.

Therefore, by inserting the corresponding sub function module according to the model and processing the option in the factory mode according to the inserted sub function module, insert the new sub function module or upgrade the function of the option processed by the existing sub function module. (Up-grade) requires a change of system, so you will have to go through the necessary steps when you first produce the product.

That is, when a new sub function module is inserted, the system checks the operation state of the system, goes through a factory mode for designing options executed in the newly inserted sub function module, and then performs a process of checking whether the OSD function is normally performed. do. The same applies to upgrading a function of an existing sub function module or deriving a function of an existing sub function module.

However, according to the conventional option processing method of inserting the conventional sub function module, the following problem occurs.

That is, the option processing system provided in the sub function module inserted in the television or monitor related product is processed without the linkage between hardware and software. Therefore, when upgrading or deriving a function of a sub function module or inserting a new sub function module, the system needs to be changed and the specification cannot be changed by the user.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to detect whether or not a sub function module having a subprogram for a sub function of a television or monitor related product is inserted in a main function module, and It is to provide an option processing method of a sub function module that can implement the option processing provided by the sub function module through the function module and the mutual interface in conjunction with hardware and software.

An operation flowchart for performing an option processing method of a sub function module according to the present invention is shown.

Referring to FIG. 1, a system for automatically processing an option when inserting a sub function module controls the system as a whole, and when it is detected that the sub function module 30 is inserted from the module detection unit 20, the inserted sub function is inserted. A microprocessor 10 that performs an interface operation with a function module, and a module detector 20 that detects whether a plurality of subfunction modules 30 provided in a set are inserted and inputs the same to the microprocessor 10. ) And an OSD unit for displaying OSD characters indicating the function of the sub function module 30 under the control of the microprocessor 10.

Here, the module detecting unit 20 determining whether the sub function module 30 is inserted will be described in detail with reference to FIG. 2.

The module detecting unit 20 detects whether the reed switch 22 is opened and shorted and opened according to whether the sub function module is inserted, and whether the reed switch 22 is opened or closed. The module detecting IC 21 includes a detection terminal for transmitting a signal and a control terminal for interfacing with a sub-function module inserted into the set under the control of a microprocessor.

The reed switch 22 is installed in one-to-one correspondence with a plurality of sub-function modules 30 inserted into the set, and the detection terminal of the module detection IC 21 corresponds one-to-one with the reed switch 22.

For example, when the module 1 (31) is not inserted among the plurality of sub-function modules 30 inserted into the set, the insertion of the sub-function module 1 (31) is not performed. A lead of the reed switch 22 for detecting whether the lead is opened with the fixed contact. Accordingly, the voltage applied from the constant voltage terminal Vcc does not flow to the open reed switch 22, but the first terminal detecting whether the reed switch 22 corresponding to the sub function module 1 is opened among the detection terminals of the module detection IC. Applied to the detection stage. The first detection terminal compares the applied voltage with a preset reference voltage Vref and inputs a high signal to the microprocessor 10 because the applied voltage is higher than the reference voltage.

When the microprocessor 10 operates normally, it is checked whether the low signal is input from the module detector 20 (S303). At this time, the module detector 20 inputs the low or high signal to the microprocessor 10 by the method described above.

When the microprocessor 10 receives a low signal from the module detector 20, the subprogram of the sub-function module corresponding to the main program of the microprocessor 10 and the detection terminal of the module detector 20 to which the low signal is input Interface operation between the through the control terminal of the module detecting unit 20 (S304).

When the interface operation between the microprocessor 10 and the corresponding subfunction module is performed, the OSD unit may display OSD characters displaying option information provided by the subfunction module while executing a subprogram that executes the functions of the subfunction module. 40) (S305).

After the subprogram and OSD display of the corresponding subfunction module are inserted, when the power is cut off and then applied again (S306), the main program of the microprocessor 10 and the subprogram of the inserted subfunction module are executed in association. While executing a new main program (S307).
