Description

Method and system for supporting multiple infrared remote controllers for electronic equipment

Technical field

The present invention relates to remote control technology, and more particularly to a method and system for supporting an electronic device to support a plurality of infrared remote controllers.

Background technique

Network set-top boxes have entered a period of rapid development. Most of the network set-top boxes on the market use infrared remote controls for remote control. The emergence of the network set-top box infrared remote control has added a member to the family mid-infrared remote control family (TV infrared remote control, air-conditioning infrared remote control, DVD infrared remote control, etc.), which makes the infrared remote control in the home more confusing. When the network set-top box remote control fails, the existing infrared remote control in the home cannot be used, and only the infrared remote controller of a specific manufacturer can be purchased, thereby causing waste of resources.

As shown in Figure 1, the infrared remote control is mainly composed of an infrared light emitting diode, an infrared receiving diode and related working circuits. The infrared light-emitting transistor is integrated on the remote control and emits infrared light after being electrically conductive. The infrared receiving diode is integrated on the controlled appliance. When receiving the infrared light, it will cause a change in the current in the circuit to control the appliance.

The main control chip IC1 in the infrared light-emitting diode circuit controls the LED to emit information including Command (Address) and Address (Address) in the form of infrared light at a time. The infrared receiving diode circuit only passively receives Command and Adrress information, and further processing of this information is handled by a program running in the main control chip IC2. In general, the Address information sent in IC1 is fixed, and the Address information processed in IC2 is also fixed, so that the infrared remote control can be matched. If IC2 only processes Command whose Address is 0XFF, then only IC1 that sends Address is 0XFF can match it, and IC1 that sends any other Address cannot control it.

The multi-function infrared remote control already available on the market can realize the purpose of controlling a plurality of home appliances by one remote controller. The biggest difference between the multi-function infrared remote control and the ordinary remote control is that there are flash (flash) areas for storing different Address and corresponding Comannd on the remote end. Due to the limited storage area Flash, it is impossible to store all infrared addresses and their commands on the market. Therefore, the multi-function infrared remote controller also integrates the infrared receiving diode D1 to realize the "learning" function of the remote controller, as shown in Fig. 2.

The first use of the multi-function infrared remote control requires pairing. The multi-function infrared remote control will have a search function. As long as the infrared light-emitting diode D2 of the infrared remote control is facing the controlled appliance, and then click the search function, the main control chip IC3 will read the Address and Command in the Flash, one by one. The controlled appliance performs matching, and when the pairing is successful, the search can be stopped, and the multi-function remote controller is used to control the home appliance. When searching for the entire Flash and not finding the paired Address and Command, you need to use the infrared remote control learning function. This learning function requires an infrared remote control that can control the controlled appliance, and then follow the “learning” instructions of the multi-function remote control. If you click the left button of the existing remote control A, press the left button of the multi-function remote control, so that the multi-function remote control records the left-key value of the remote control A. After learning all the keys of the remote control A, you can use the multi-function remote control instead of the remote control A.

However, the inventors of the present invention have found that the existing infrared remote controller has the following disadvantages:

(1) When the network set-top box remote controller is broken, if a multi-function remote controller is used for replacement, additional overhead is required.

(2) The learning function of the multi-function infrared remote control depends on the remote control that can work normally. If the multi-function infrared remote controller does not pre-store the key value of the network set-top box remote controller, since the existing infrared remote controller is broken, the learning function of the multi-function remote controller cannot be turned on. Even if the user buys a multi-function infrared remote control, the user cannot control the network set-top box.

The process runs in the memory, and when the user state process is not started, the infrared remote controller is used to perform a boot operation in the kernel state process, which can support various existing infrared remote controllers, and does not require the operation of additional hardware devices.

In step 401, after the user state process is started, after the user state process receives the signal of switching from the first infrared remote controller to the second infrared remote controller, the second infrared remote controller is used as the current infrared remote controller.

Thereafter, proceeding to step 402, the user state process stores the power-on key value corresponding to the second infrared remote controller in a memory running in the kernel state process.

A fifth embodiment of the present invention relates to a method of an electronic device supporting a plurality of infrared remote controllers. FIG. 5 is a schematic flow chart of a method for supporting a plurality of infrared remote controllers of the electronic device.

The fifth embodiment is improved on the basis of the fourth embodiment. The main improvement is that the kernel state process uploads the identifier and the key value to the bus, and judges the validity of the identifier in the user state process. Supporting differently-identified infrared remote controls does not affect the speed of the entire system. Specifically:

As shown in FIG. 5, the method further includes the following steps:

In step 501, after the user state process is started, the kernel state process receives the infrared signal sent by the infrared remote controller and reads the identification and the key value from the infrared signal.

The function is performed based on the reference key value.

Convert the key values of different infrared remote controllers uploaded to the bus into the reference key value and then execute The corresponding functions are more stable and convenient when supporting multiple infrared remote control operations.

In addition, it can be understood that the key functions can be directly executed without converting the key values.

A sixth embodiment of the present invention relates to a method of an electronic device supporting a plurality of infrared remote controllers. The sixth embodiment is improved on the basis of the fifth embodiment, and the main improvement is that the key value of the infrared remote controller is learned when there is no identifier corresponding to the infrared remote controller in the database. Specifically:

After step 504, the following steps are also included:

If the identifier does not exist in the database, the corresponding function is selected for the key value of the infrared remote controller to form a configuration.

Preferably, each infrared signal corresponding to each key value of the infrared remote controller is received in a predetermined order to select a corresponding function for the key value of the infrared remote controller to form a configuration.

The methods in the first to sixth embodiments will be further described in detail below by taking a network set top box and a Linux system as an example.

The operating system in the network set-top box generally uses the Linux kernel to support the underlying device. The infrared remote control driver of the network set-top box is also supported by the Linux kernel. Usually, the processing flow of the Linux kernel to the infrared interrupt is shown in Figure 6. Linux systems are divided into kernel mode and user mode for security and efficiency reasons. The infrared driver works in the kernel mode. When a button is pressed, an infrared interrupt is generated. In the interrupt handler, the address (address, equivalent to the identifier) is judged to be valid. If the address is valid, the Command representing the key value will be transferred to the device bus. If the address is invalid, it will be ignored and no processing will be done.

If the button is active, it is necessary to read Commnad from the device bus and parse it at the user mode. The existing operating system handles the infrared remote control, and the kernel mode is used directly. The process of the Linux infrared kernel state shown in Figure 6 creates two threads in the user state: Command reads the thread InputReader and the Command dispatch thread InputDispatcher. The InputReader is responsible for reading the Command data on the device bus and parsing it to the InputDispatcher, and then the InputDispatcher notifies the corresponding application to perform the operation.

As can be seen from the above, Linux only handles drivers in the kernel mode, and infrared drivers are provided by hardware vendors. Different hardware vendors use different Addresses to distinguish them. Therefore, to use a manufacturer's infrared device, you need to load the device manufacturer's driver. In the driver of the equipment manufacturer, the address generated by the infrared interrupt is judged. If it is valid, the Command is uploaded to the bus, otherwise the infrared interrupt is directly ignored. Therefore, the supported infrared remote controls are very limited.

In order to support various infrared remote controllers at the same time, in a preferred embodiment of the present invention, the processing flow of the operating system to the infrared remote controller is as shown in FIG. Compared with Figure 6, the Linux kernel state no longer determines whether Address is valid or not, and directly uploads the data obtained by the infrared interrupt to the device bus. In the user mode, it is determined whether the Address is in the database. If it exists, the correct mapping <Address2, Command2> corresponding to <Address, Command> is read, and then Command2 is parsed and the operation is performed. If the Address is not in the database, the infrared learning function of the network set-top box is turned on, and the remote controller key value of the Address is learned and saved.

The reason why the address is valid in the user mode is because the kernel mode supports the normal operation of the entire system. If the work is too heavy, it will seriously affect the running speed of the entire system. And because the entire system is built on the Linux kernel, the Linux kernel does not allow this time-consuming operation to be done by the kernel state.

As shown in Table 1, different infrared remote controllers have different key values for the same operation. For example, the left key of the infrared remote control A is 0x01, and the key of the left key of the infrared remote control B is 0x02. Although they are all left keys, the key values are different. Therefore, it is necessary to convert the key values of different infrared remote controllers to the bus for conversion, and the work is performed in the database. The contents of the database are shown in Table 1. In a preferred example, as long as the left button is converted to 0x1A. Of course, other in the present invention In the embodiment, the key value may not be converted.

Table 1 database storage content

AddressAddress	CommandCommand	Command2Command2
AA	0x010x01	0x1A0x1A
BB	0x020x02	0x1A0x1A

The operating system will start two threads in user mode to handle the infrared remote control: read the data thread InputReader and distribute the Command thread InputDispatcher. The InputReader thread reads the Address and Command on the bus. Then look up the Address in the database. If it can be found, it will notify the InputDispatcher to distribute the event after parsing the Command. Otherwise, the user will be prompted to start the button learning function of the remote controller.

As shown in Figure 8, the remote control learning function of the network set-top box does not need to rely on other infrared remote controllers, and only the remote controller to be learned needs to follow the prompts. Preferably, the network set top box learns the following keys in order: confirmation key, left key, right key, up key, down key, return key, sound plus key, sound minus key, mute key, HOME key, and shutdown key 11. If there is no relevant button on the remote control being learned, just wait 10 seconds to skip the learning function of this button. Of course, in other embodiments of the invention, the keys can also be learned in other sequences.

In this way, 10 network set-top boxes using 10 different infrared remote controllers can be upgraded to the same system version, and each infrared remote controller can be used normally, with strong compatibility and convenient use.

It can be understood that the above is only a preferred example, and the corresponding steps can be deleted or added as needed. And the above method can also be applied to other electronic devices and operating systems other than network set-top boxes and Linux systems, such as smart TVs and windows systems.

The method embodiments of the present invention can all be implemented in software, hardware, firmware, and the like. Regardless of whether the invention is implemented in software, hardware, or firmware, the instruction code can be stored in any class. Type of computer accessible memory (eg, permanent or modifiable, volatile or non-volatile, solid or non-solid, fixed or replaceable media, etc.).
