As shown in fig. 1, the television system of the present invention mainly includes: remote controller, OSD display element, microprocessor MCU and memory, wherein:
the remote controller is used for function operation and event triggering, and the remote controller keys in the embodiment are divided into key areas corresponding to user modes, which are specifically described as follows;
the MCU is used for receiving the infrared signal sent by the remote controller, acquiring a key code value after detecting the infrared signal, comparing the key code value with an effective key code value group corresponding to a user mode stored in the memory, and executing a function corresponding to the key code value if the comparison result shows that the key code value of the key exists in the effective key code value group in the user mode; in addition, the MCU is also used for setting the flag value of the user mode flag bit in the system to the value corresponding to the user mode according to the user mode selected by the user.
The memory EEPROM mainly stores effective key code value groups and flag bit (flag) values corresponding to all user modes, the remote controller key code values are stored in groups according to divided regions, and each group contains key code values in a key region corresponding to one user mode.
Programs needed by the MCU to execute various processing are stored in the memory FLASH;
the OSD display unit is used for displaying related prompt information, and is convenient for operation and reminding.
The remote controller key layout according to the embodiment of the present invention is shown in fig. 2, the remote controller is provided with a plurality of user mode keys, which respectively correspond to different user groups, and a user can switch various user modes by operating different user mode keys.
The keys on the remote controller are divided into a plurality of areas corresponding to the user modes and are respectively used for operating in different remote controller user modes. In the embodiment of the invention, the common mode corresponds to the area formed by all the keys on the remote controller, and all the keys on the remote controller are effective in the common mode; the old man mode corresponds to a region formed by keys in a region 1 and a region 2 on the remote controller, in the old man mode, the television only responds to the keys in the region 1 and the region 2, when other keys are pressed, the television does not respond, and a prompt message for prompting that the function in the mode is invalid appears on a display screen of the television; in the child mode, the television only responds to the user mode switching key, when the user presses any key of the ordinary or old people as shown in fig. 2, the process of user mode selection is entered, the television prompts the user to input a password, when the user inputs the password, the user mode can be switched to the user mode selected by the user, and if the user presses other keys, the television displays OSD prompt information on the display screen, namely that the key in the current mode is invalid.
In the television software, the key code value is the only standard for distinguishing the key functions of the remote controller, when the function keys on the remote controller are defined with corresponding functions, the television software stores the key code value corresponding to the function keys and the functions corresponding to the code value, a user presses a certain key on the remote controller in the process of using the remote controller, the remote controller sends a control signal to a controlled electric appliance, the television remote control receiving device receives the control signal and then decodes the control signal, and the television MCU controls the television to execute the functions corresponding to the function keys according to the decoded key code value.
In the embodiment of the invention, the preset key values are stored in the EEPROM in groups, different user modes correspond to different key code value groups (effective key code value groups), under different user modes, the MCU can call different effective key code value groups according to different requirements, for example, only the key code value groups corresponding to the keys in the area 1 and the area 2 are called under the old man mode, at the moment, the keys in the remote controller key operation area 1 and the area 2 can be matched with the key code values in the key code value groups stored in the television software, so that corresponding functions are realized according to the matched key code values, and even if the keys outside the area 1 and the area 2 are pressed, the television MCU cannot find the key code values matched with the keys without action, thereby realizing the effect of key shielding.
In the EEPROM, the value of a user mode flag bit (flag) when the remote controller is normally shut down last time is refreshed to be the current flag bit value, so that the default remote controller user mode is the user mode when the remote controller is shut down last time. When a user changes the user mode of the remote controller every time, the user mode can be switched through a common user mode key, an old user mode key and a child user mode key preset on the remote controller, the software receives the key pressing values of the remote controller and then carries out corresponding judgment and matching, the value of a user mode flag bit (flag) in the software is immediately changed to a corresponding value, and the user mode of the remote controller is changed accordingly.
The following operation flow for selecting a user mode according with the user's own needs is specifically described, and as shown in fig. 3, the operation flow specifically includes the following steps:
(1) when a user starts up for the first time, the MCU reads the default value of a flag bit flag of a remote controller user mode in the EEPROM, and if the flag is 1, the current remote controller user mode is a common user mode; if the flag is 2, the current remote controller user mode is an old user mode; if the flag is 3, the current remote controller user mode is a child user mode;
(2) when a user wants to switch to other user modes, the user mode can be switched to different user modes by pressing down a user mode key corresponding to the remote controller, and the MCU changes the value of a user mode flag bit flag in the EEPROM into a value corresponding to the mode selected by the user;
(3) after the user selects the user mode, the television is controlled by the keys of the remote controller, and only the keys which are effective in the mode can obtain the response of the television.
After the user selects the user mode of the remote controller, the working flow of each user mode of the remote controller is as shown in fig. 4, and the method specifically comprises the following steps:
1. when a user starts up for the first time, the MCU reads a default remote controller user mode flag value flag in the EEPROM;
2. if the flag is 1 (common mode), the MCU runs a control program corresponding to the common mode, and a user can complete the function operation of all keys on the remote controller in the operation mode; if the flag is 2 (old man mode), the MCU only calls the effective key code value group corresponding to the old man mode stored in the EEPROM, when the keys in the area 1 and the area 2 shown in FIG. 2 are pressed, the MCU searches the key code value matched with the key from the effective key code value group corresponding to the old man mode to complete the function corresponding to the key, when the user presses the keys out of the area 1 and the area 2 shown in FIG. 2, the MCU cannot find the key code value matched with the key, and OSD prompt information is displayed on a display screen of the television, wherein the key in the current mode is invalid; if the flag is 3 (child mode), the MCU can only call the key code value of the mode switching key group stored in the EEPROM, when a user presses any key of 'ordinary' or 'old man' as shown in FIG. 2, the flow of user mode selection is entered, the television prompts the user to input a password, after the user inputs the password, the user can switch to the user mode selected by the user, and if the user presses other keys, OSD prompt information 'the current mode key is invalid' is displayed on the display screen of the television.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
