Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Fig. 1 is a schematic diagram of an electronic system of the present invention, and fig. 2 is a flowchart of a control method of the electronic system of the present invention, referring to fig. 1 and fig. 2. The electronic system 1 includes a main control device 2, a display device 3, an input device 4 and a connection device 5. The main control device 2 is used for sending display data to the display device 3, the display device 3 is used for displaying the display data, and the input device 4 comprises at least one of a keyboard, a mouse, a control joystick and a touch input board.
The connection device 5 is connected to the main control device 2, the display device 3, and the input device 4 in a communication manner. Specifically, the connection device 5 includes a first interface 51, a second interface 52, a third interface 53, and a processing unit 54. The first interface 51 is used for communicationA signal connection input device 4, the first interface 51 is used for receiving an input event provided by the input device 4; the second interface 52 is used for communication connection with the main control device 2; the third interface 53 is used to communicatively connect the display apparatus 3, for example, the display apparatus 3 includes a scalar unit 31, the third interface 53 of the connection apparatus 5 and the scalar unit 31 of the display apparatus 3 can be based on a universal asynchronous receiver/transmitter (UART) or based on an integrated circuit bus (I)2C-bus) communication connection. The scalar unit 31 may be, for example, a scalar IC, which is used to integrate other ICs collocated on the periphery of the display: such as ADC and PLL, OSD, FRC, TMDS, MCU, Scalar, Tcon, LVDS, RSDS, etc. And the communication link described herein includes, but is not limited to, a wireless communication link or a wired communication link.
The processing unit 54 is used for analyzing the input event from the first interface 51; wherein, if the input event is an on-screen menu opening instruction, the on-screen menu opening instruction is transmitted to the display device 3 through the third interface 53; if the input event is a non-OSD-related command, the input event is transmitted to the host device 2 through the second interface 52.
The specific process of the connection device 5 for confirming whether the input event is the on-screen menu opening instruction is as follows: the on-screen menu opening command (e.g., alt key + O key) is preset in the processing unit 54, and the processing unit 54 compares the input event with the on-screen menu opening command in real time, for example, when the comparison result is a match, the connection device 5 determines that the input event is the on-screen menu opening command, and when the comparison result is not a match, the connection device 5 determines that the input event is not the on-screen menu opening command.
In summary, the control method of the electronic system comprises the following steps:
s1, the connecting device 5 receives and analyzes an input event provided by the input device 4;
s2, if the input event is a screen menu opening instruction, executing the step S3;
and S3, the connecting device 5 transmits the on-screen menu opening instruction (such as an alt key + O key) to the display device 3, and the display device 3 displays an on-screen menu.
Thus, the user only needs to input the on-screen menu opening instruction (alt + O key) by using the input device 4 (e.g. keyboard), and the electronic system 1 can open the on-screen menu through the display device 3.
When the connection device 5 analyzes the input event, if the input event is found to be an on-screen menu opening instruction, the connection device 5 intercepts the event, does not transmit the event to the main control device 2, and only transmits the event to the display device 3 (for example, a scalar unit). The display device 3 then reopens the on-screen menu.
After step S3, the method further includes steps S4 and S5, step S4: if the connection device 5 does not receive the on-screen menu exit instruction, the connection device 5 transmits the next input event provided by the input device 3 to the display device 3. And the display device 3 operates the on-screen menu according to the received next input event and executes a corresponding function. Step S5: if the connection device 5 receives the on-screen menu exit instruction, the connection device 5 receives and parses the next input event provided by the input device 3, and goes to step S2.
Specifically, after the processing unit 54 transmits the on-screen menu opening instruction to the display device 3 through the third interface 53, the processing unit 54 continues to analyze the second event from the first interface 52 or the third interface 53, wherein if the processing unit 54 determines that the second event is the non-on-screen menu exit instruction, the processing unit 54 transmits the next input event received by the first interface 51 after the second event to the display device 3 through the third interface 53; if the processing unit 54 determines that the second event is the on-screen menu exit instruction, it transmits the next input event received by the first interface 51 after the second event to the main control device 2 through the second interface 52.
In the present embodiment, the connection device 5 receives and interprets an input event (for example, ESC key) provided by the input device 4 as the on-screen menu exit command. In other embodiments, if the display device 3 exits from displaying the on-screen menu, the display device 3 sends the on-screen menu exiting command to the connection device 5.
And step S2 further includes:
s21, if the input event is a non-screen menu related instruction, executing a step S6;
s6, the connecting device 5 transmits the input event to the main control device 2.
In summary, the input event of the input device is analyzed by the connection device, when the input event is an on-screen menu opening instruction, the connection device instructs the display device to open the on-screen menu, and then the selection can be performed by the input device without an entity key or a specific application program.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
