Wherein, when the power supply state is the power-on state, the operation mode is the audio-visual mode, and the function signal is a mode switching key or a function key corresponding to the audio-visual mode, the keyboard encoder determines that the function signal is valid. And when the power state is the power-on state, the operation mode is the computer mode, and the function signal is the function key of the corresponding audio-visual mode, the keyboard encoder determines that the function signal is invalid. the

In addition, when the power supply state is a shutdown state or a standby state, and the function signal is a mode switching key or a power key, the keyboard encoder determines that the function signal is valid.

Below are several specific embodiments according to the present invention. the

FIG. 1 is a schematic diagram of the system architecture of a system that uses system power status and operating mode to control boot behavior according to an embodiment of the present invention. A system for controlling boot behavior using system power status and operating mode according to an embodiment of the present invention includes a keyboard encoder 100 , an input unit 110 , a computer system 120 and a system power status pin 130 . the

The keyboard encoder 100 is used to receive a signal (function signal) input by the input unit 110, and can determine the validity of the received signal, that is, whether to transmit it to the computer system 120 or execute a corresponding operation. Wherein, the input unit 110 may be a remote controller or a keyboard. The system power status pin 130 is a pin that exists through hardware signal combination, and is used to record the power status of the computer system 120, such as power on (Power On), power off (Power Off), and standby (Standby) status. the

The keyboard encoder 100 can check the system power status pin 130 and the operation mode 101 of the corresponding computer system to determine whether the function signal received by the input unit is suitable for the current operation mode, and define related operations. It should be noted that the current operating mode of the computer system 120 or the operating mode before the computer system 120 is shut down can be recorded in the keyboard encoder 100. the

FIG. 2 is an operation flow chart of a method for controlling boot behavior using system power state and operation mode according to an embodiment of the present invention. the

According to the method for controlling the booting behavior by using the system power state and operation mode according to the specific embodiment of the present invention, first, as in step S201, a system power state pin 130 is provided for recording the power state of the computer system. Next, in step S202 , the function signal sent by the input unit 110 is received by the keyboard encoder 100 . the

Afterwards, in step S203, the keyboard encoder 100 obtains the power status of the computer system 120 from the checking system power status pin 130, and checks the operation mode 101 of the corresponding computer system 120 in step S204. Finally, in step S205 , it is determined whether the function signal received by the input unit 110 is valid according to the power state and the operation mode 101 of the computer system 120 . the

FIG. 3 is a flowchart of a method for judging a function signal according to a specific embodiment of the present invention. First, in step S301, a function signal sent by the input unit 110 is received. Next, in step S302, the power state of the computer system 120 is determined. the

When the power state is the power-on state, as in step S303, the current operation mode of the computer system 120 is determined. When the operation mode is the audio-visual mode, as in step S304, it is judged whether the function signal is a mode switching key or a function key of the corresponding audio-visual mode, if the function signal is not a mode switching key or a function key of the corresponding audio-visual mode, then as in step S305, the keyboard The encoder 100 judges that the function signal is invalid, and does not perform the operation corresponding to the function signal; on the contrary, if the function signal is a mode switching key or a function key corresponding to the audio-visual mode, then as in step S306, the keyboard encoder 100 judges the function signal To be effective, and execute the operation corresponding to the function signal or forward it to the computer system 120 . the

And when the power state is the power-on state and the operation mode is the computer mode, then as in step S307, it is judged whether the function signal is a function key of the audio-visual mode, if the function signal is a function key of the corresponding audio-visual mode, then as in step S305, the keyboard Encoder 100 determines that the function signal is invalid, and does not execute the operation corresponding to the function signal; otherwise, as in step S306, the keyboard encoder 100 determines that the function signal is valid, and executes the operation corresponding to the function signal or transfers it to the computer system 120. the

On the other hand, when the power state is off state or standby state. Then, as in step S308, it is determined whether the function signal is the function of the corresponding mode switching key or power key. If the function signal is the function of the corresponding mode switching key, then as step S309, the keyboard encoder 100 causes the computer system 120 to start up and execute in the operation mode of the corresponding mode switching key; and when the function signal is the function of the corresponding power key, Then, in step S310 , the keyboard encoder 100 causes the computer system 120 to start up and execute in the previous operation mode recorded in the keyboard encoder 100 . It should be noted that, in the above-mentioned booting action, if the power state of the computer system 120 is in the standby state, the keyboard encoder 100 does not actually perform the booting action but performs a wake-up (Wake Up) action. the

Therefore, the system and method for controlling the boot behavior by using the system power state and operating mode provided by the present invention can use the system power state and operating mode to control the boot behavior of the computer system through the keyboard encoder, thereby providing more convenient The operation form is given to the user, and the incorrect behavior is avoided, which will cause system error or data loss. the
