Description

Remote controller, intelligent equipment and configuration method

Technical Field

The application relates to a method for configuring a remote controller through intelligent equipment, corresponding intelligent equipment and a corresponding remote controller.

Background

The universal remote controller is also called a universal remote controller, and refers to a remote controller capable of controlling a plurality of controlled devices, which is different from a special remote controller capable of controlling only one specific controlled device.

One common configuration method of a universal remote controller is to store multiple sets of remote control instruction sets in advance during manufacturing, where each set corresponds to a specific controlled device. Before the universal remote controller is used, an adaptation process between the universal remote controller and a controlled device is firstly carried out. This can be simply expressed as the universal remote controller traversing a plurality of sets of prestored remote control instruction sets and transmitting them one by one to the controlled apparatus, and the user observing whether the controlled apparatus reacts correctly, thereby determining which set of remote control instruction set is suitable for the controlled apparatus. The universal remote control requires the above adaptation process to be repeated each time the controlled device is replaced. The universal remote control also needs to repeatedly perform the above adaptation process if it is desired to switch control between two or more controlled devices. This brings users with bad experience, including long time consumption in the adaptation process, cumbersome operation, etc.

Disclosure of Invention

The technical problem to be solved by the application is to provide a method for configuring a remote controller through intelligent equipment, which can complete a configuration process quickly and efficiently. To this end, the present application also provides a smart device for configuring a remote controller, and a remote controller for receiving the configuration of the smart device.

In order to solve the technical problem, the application provides a remote controller which comprises a processor, a memory, an infrared receiving and transmitting unit and a key area. The memory is used to non-volatilely store one or more sets of configured remote control instructions. The infrared transceiving unit is used for transmitting and/or receiving infrared signals. The key area is composed of a plurality of keys, and comprises at least one switching key for realizing the switching of the remote control instruction set. The processor is configured to perform the following operations: receiving and storing one or more groups of configured remote control instruction sets from the intelligent equipment; each configured set of remote control commands is configured based on a virtual remote control interface having substantially the same or substantially the same key layout as the remote control. And responding to a unique switching key to sequentially and circularly switch and load among the multiple groups of remote control instruction sets, or responding to multiple switching keys to correspondingly switch and load among the multiple groups of remote control instruction sets. And mapping the functions of all virtual keys in a group of currently loaded remote control instruction sets and the corresponding remote control signals to the keys at corresponding positions in the key area respectively.

The remote controller does not need to be adapted when the controlled device is replaced, and only a unique switching key or one of a plurality of switching keys needs to be pressed. The remote controller can write a remote control instruction set into the remote controller in a whole group during configuration, and can delete and/or modify the stored remote control instruction set. The remote control instruction set written and stored by the remote controller is configured based on the virtual remote controller interface with the same or similar (approximately same) layout as the key area of the remote controller, so that the functions and remote control signals of all virtual keys can be conveniently mapped to the entity keys at corresponding positions after each group of remote control instruction sets are loaded.

Preferably, the key area only comprises one switching key used for sequentially and circularly switching and loading among a plurality of groups of remote control instruction sets; different pressing times of the unique switching key correspond to different groups of remote control instruction sets. Or the key area comprises a plurality of switching keys which are respectively used for switching to load a corresponding group of remote control instruction sets. This is two preferred implementations of the key area, and the switch key in the physical form can be used to quickly switch the loaded remote control instruction set, thereby facilitating quick replacement of the controlled device without adaptation.

Preferably, the remote controller further comprises one or more indicator lights, different indicator lights representing different sets of remote control instruction sets currently loaded. The indicator lights may be used to allow the user to know which set of remote control instruction sets is currently loaded, thereby facilitating the user to know which controlled device the remote control is currently available to remotely control.

Further, the processor is further configured to perform the following operations: receiving an instruction from the intelligent equipment, deleting one or more groups of remote control instruction sets stored in the memory according to the instruction, or adjusting the sequence of sequential and cyclic switching of the multiple groups of remote control instruction sets according to the unique switching key, or adjusting the corresponding relation between the multiple groups of remote control instruction sets and the multiple switching keys. This provides the user with the opportunity to custom adjust the set of remote control instructions stored within the remote control.

Further, the identical key layout means that the number of virtual keys on the virtual remote controller interface is identical to the number of keys in the key area, and the distribution, arrangement and relative position relationship between the virtual keys on the virtual remote controller interface and the keys in the key area are identical. And under the completely same key layout, the processor respectively maps the functions of the virtual keys and the corresponding remote control signals to the keys at corresponding positions. This is a preferred implementation of the remote control to load the remote control instruction set.

Further, the substantially same key layout means that the number of virtual keys on the virtual remote controller interface is substantially the same as the number of keys in the key area, and/or the distribution, arrangement, and relative position relationship between the virtual keys on the virtual remote controller interface and the keys in the key area are substantially the same. Under the same key layout, a sub-set containing most of keys is selected from the key area, a sub-set containing most of virtual keys is selected from the virtual remote controller interface, and the key sub-set and the virtual key sub-set are the same in number, distribution, arrangement and relative position relation. The processor maps the functions of the virtual keys belonging to the virtual key subset and the corresponding remote control signals to the keys belonging to the corresponding positions of the key subset respectively. This is another less preferred implementation of the remote control to load the remote control instruction set.

Optionally, the remote controller further comprises a communication unit for communicating with the intelligent device; the communication unit of the remote controller and the communication unit of the intelligent device are of the same type. A new communication channel is designed between the remote controller and the intelligent equipment, so that the remote controller and the intelligent equipment can communicate without an infrared receiving and transmitting unit of the remote controller and the intelligent equipment.

The application also provides intelligent equipment which comprises a processor, a memory, a display screen and an infrared receiving and transmitting unit; or the infrared receiving and transmitting unit is omitted and an external infrared receiving and transmitting accessory is changed. The memory is operable to store one or more virtual remote control interfaces, and one or more sets of remote control instructions. The display screen is used for displaying. The infrared transceiver unit or the infrared transceiver accessory is used for transmitting and/or receiving infrared signals. The processor is configured to perform the following operations: determining a virtual remote controller interface on the intelligent equipment, wherein the determined virtual remote controller interface and a remote controller to be configured have completely the same or approximately the same key layout; the virtual remote controller interface comprises at least one virtual switching key for realizing the switching of the remote control instruction set. And configuring a remote control instruction set on the intelligent device according to the determined virtual remote controller interface. And sending one or more configured sets of remote control instructions to the remote control.

The intelligent device can be used for configuring the remote controller, and comprises the steps of writing a configured remote control instruction set into the remote controller, adjusting a remote control instruction set stored in the remote controller and the like. When the intelligent device is configured with the remote control instruction set, the intelligent device is configured on the basis of the virtual remote controller interface which has the same or similar (approximately same) layout with the key area of the remote controller to be configured, so that the visual feeling of the user during configuration is improved, and the learning and memory time of the user during use of the remote controller is reduced.

Further, the intelligent device further comprises a network unit, and the network unit is used for realizing network communication. The virtual remote controller interface and the remote control instruction set are stored in a remote server partially or completely and are acquired by the intelligent equipment through accessing the remote server through the network unit. The data is stored in a local or remote server of the intelligent equipment, can be set according to actual conditions, and has no essential difference when in use.

Further, the determining the virtual remote control interface on the smart device refers to: the processor displays pictures of one or more virtual remote controller interfaces on the display screen, and a user selects a virtual remote controller interface with the same or approximately the same key layout as the key area of the remote controller to be configured; the processor determines a virtual remote control interface based on a user selection. Or, the determining the virtual remote control interface on the smart device means: the processor displays a selection frame and/or an input frame on the display screen, and a user selects and/or inputs information of the remote controller to be configured; then the processor obtains query results from a plurality of virtual remote controller interfaces stored in a memory or a remote server according to the information selected and/or input by the user; the processor determines a virtual remote control interface based on the final query result from the local or remote server. Or, the determining the virtual remote control interface on the smart device means: the intelligent equipment takes a picture or a video of a key area of the remote controller to be configured through the picture or video taking unit, then the processor or the remote server identifies the key layout of the remote controller to be configured based on an image or video analysis technology, and selects a virtual remote controller interface with the same or approximately the same key layout based on an identification result; the processor determines a virtual remote control interface based on a selection of a local or remote server. Or, the determining the virtual remote control interface on the smart device means: the intelligent equipment establishes communication with the remote controller to be configured, and the processor acquires information from the remote controller to be configured; then the processor returns a unique query result from a plurality of virtual remote controller interfaces stored in the memory or the remote server according to the acquired remote controller information; the processor determines a virtual remote control interface based on the unique query result. This is four preferred implementations of "determining a virtual remote control interface" to determine a virtual remote control interface having the same or similar (roughly the same) key layout as the physical form of the remote control to be configured. Therefore, the remote control instruction set configured on the virtual remote controller interface can be directly mapped to the keys at the corresponding positions of the remote controller in the entity form, and the learning cost of a user is reduced.

Further, the configuring, on the smart device, the remote control instruction set according to the determined virtual remote control interface means: and selecting at least one group of remote control instruction sets based on the determined virtual remote controller interface and the virtual switching key and the controlled device to be controlled, and corresponding each group of remote control instruction sets to different triggering times of the unique virtual switching key or corresponding each group of remote control instruction sets to each of a plurality of virtual switching keys. This is an overall description of "configuring a remote control instruction set according to a virtual remote control interface".

Preferably, configuring, on the smart device, a remote control instruction set according to the determined virtual remote control interface means: only one virtual switching key is arranged on the interface of the virtual remote controller; the processor displays a selection frame and/or an input frame on the display screen, and a user selects and/or inputs information of a controlled device which is expected to be controlled by a unique virtual switching key under different triggering times; then the processor returns the query result from a plurality of groups of remote control instruction sets stored in the memory or the remote server according to the determined virtual remote controller interface and the information selected and/or input by the user; the final processor determines a set of remote control instruction sets for which a unique virtual switch key corresponds at each activation. Or, the configuring, on the smart device, the remote control instruction set according to the determined virtual remote controller interface means: the virtual remote controller interface comprises a plurality of virtual switching keys; the processor displays a selection frame and/or an input frame on the display screen, and the user selects and/or inputs information of a controlled device which is expected to be controlled after each virtual switching key is triggered; then the processor returns the query result from a plurality of groups of remote control instruction sets stored in the memory or the remote server according to the determined virtual remote controller interface and the information selected and/or input by the user; and finally, the processor determines a corresponding group of remote control instruction sets after each virtual switching key is triggered. This is two preferred implementations of "configuring the remote control instruction set according to the virtual remote control interface".

Further, configuring, on the smart device, a remote control instruction set according to the determined virtual remote control interface further comprises: in a set of configured remote control instruction sets, adding functions and remote control signals thereof to virtual keys of unconfigured functions and remote control signals thereof, and/or modifying functions and/or remote control signals of virtual keys of configured functions and remote control signals thereof. This provides the user with the opportunity to customize the individual key functions. In general, the remote control signal may be automatically generated according to a user-defined key function in combination with information of a controlled device desired to be controlled, which may be preset in a memory of the smart device and/or a remote server with a database of various remote control signals of various types and brands of controlled devices and functions thereof.

A new communication channel is designed between the intelligent equipment and the remote controller, so that the intelligent equipment and the remote controller do not need to communicate through infrared receiving and transmitting units of the intelligent equipment and the remote controller.

Further, when the communication unit and the network unit are of the same type, the communication unit is omitted, and the network unit is responsible for establishing communication with a remote controller. This can simplify the structure and the volume of smart machine, reduce cost.

Detailed Description

Please refer to fig. 1, which is a first embodiment of a remote controller provided in the present application. The remote control 10 includes a processor 12, a memory 14, an infrared transceiver unit 16, and a keypad 110.

The processor 12 is, for example, one or more of a Micro Controller Unit (MCU), an micro microprocessor unit (MPU), a system on a chip (SoC), and a Central Processing Unit (CPU).

The Memory 14 is a rewritable nonvolatile Memory, such as a flash Memory, an EEPROM (Electrically Erasable Programmable Read-Only Memory), and the like. The memory 14 is used to non-volatile store one or more sets of remote control instructions.

The infrared transceiver unit 16 is used for transmitting and/or receiving infrared signals. The infrared signal may be transmitted by an infrared light emitting diode, for example, the remote controller 10 transmits an infrared remote control signal to the controlled device. The infrared signal may be received by an infrared photodiode, for example, the remote controller 10 learns the infrared remote control signals transmitted by other remote controllers. The infrared transmitting and receiving integrated tube integrates the infrared transmitting and receiving functions and can be used for replacing an infrared light-emitting diode and an infrared photosensitive diode. When the smart device 20 has the infrared transceiver unit 26 or the external infrared transceiver 36, the remote controller 10 may establish communication with the infrared transceiver unit 26 or the external infrared transceiver 36 of the smart device 20 through the infrared transceiver unit 16 by using infrared signals.

The button section 110 is composed of a plurality of buttons for receiving user input to the remote controller 10. These keys may be physical keys, touch keys, etc. The key area 110 includes at least one switch key 112 for switching the remote control instruction set, and at least one function key for implementing a remote control function of the controlled apparatus.

Referring to fig. 2, this is a partial structure of the key region 110, showing a first implementation of the switch key. The key region 110 includes only one switch key 112 for cycling through sets of remote control commands in sequence. When the unique toggle key 112 is pressed for the first time, the remote control 10 loads a first set of remote control instruction sets. When the unique switch key 112 is pressed a second time, the remote control 10 instead loads a second set of remote control instruction sets. By analogy, the single switch button 112 can cycle through the multiple sets of remote control command sets in turn based on the number of presses. For example, cycling through 4 sets of remote control instruction sets in sequence, the remote control 10 instead loads the first set of remote control instruction sets when the only switch key 112 is pressed the fifth time.

Referring to fig. 3, this is a partial structure of the key region 110, showing a second implementation manner of the switch key. The key area 110 includes a plurality of switch keys, each for switching to a corresponding set of remote control command sets, schematically represented in fig. 4 as 4 switch keys 112a to 112 d. When the first switch key 112a is pressed, the remote control 10 loads the first set of remote control commands. When the second switch button 112b is pressed, the remote control 10 loads the second set of remote control command set instead. By analogy, the plurality of switch buttons 112a to 112d can be switched arbitrarily among the same number of groups of remote control instruction sets.

Optionally, the remote control 10 also includes a plurality of indicator lights, the number of which is the same as the number of groups of switchable remote control instruction sets. Referring to fig. 4 and 5, there are schematically shown 4 indicator lights 120a through 120 d. When the remote controller 10 loads a different set of remote control instruction sets, different indicator lights 120a to 120d are illuminated for the user to understand and use. Preferably, the indicator lights 120a to 120d are located on the front face of the remote controller 10. It is further preferred that indicator lights 120 a-120 d are located in key area 110 or in close proximity to key area 110. It is further preferred that the indicator lights 120a to 120d are located immediately adjacent to the single switch key 112, as shown in fig. 4. Or further preferably, the indicator lights 120 a-120 d are immediately adjacent to the respective switch keys 112 a-112 d, as shown in fig. 5.

Please refer to fig. 6, which shows a second embodiment of the remote controller provided in the present application. The remote control 10 has a processor 12, a memory 14, an infrared transceiver unit 16, a communication unit 17 and a keypad 110. The infrared transceiver unit 16 is only used to transmit infrared remote control signals to the controlled device and/or learn infrared remote control signals transmitted by other remote controllers, and is not used to establish communication with the intelligent device 20 using infrared signals. The newly added communication unit 17 is used for communication with the intelligent device 20, for example, when the intelligent device 20 has the communication unit 27, the communication unit 17 of the remote controller 10 and the communication unit 27 of the intelligent device 20 establish communication. At this time, the communication unit 17 of the remote controller 10 and the communication unit 27 of the smart device 20 are preferably the same type, for example, any one or more of a USB communication unit, a Bluetooth Low Energy (BLE) communication unit, a ZigBee (ZigBee) communication unit, a Wireless Local Area Network (WLAN) communication unit, and a mobile network communication unit.

In the embodiment of the remote control shown in fig. 1, 6, the processor 12 is configured to perform the following operations:

first, the processor 12 is used to establish communication with the smart device 20. For example, when the smart device 20 has the infrared transceiver unit 26 or the external infrared transceiver 36, the processor 12 establishes communication with the infrared transceiver unit 26 of the smart device 20 or the external infrared transceiver 36 through the infrared transceiver unit 16 of the remote controller 10 by using infrared signals. As another example, when the smart device 20 has the communication unit 27, the processor 12 establishes communication with the communication unit 27 of the smart device 20 through the communication unit 17 of the remote controller 10.

Second, the processor 12 is configured to receive one or more configured sets of remote control instructions from the smart device 20 and to store the received one or more configured sets of remote control instructions in the memory 14 in a non-volatile manner. Each set of configured remote control instruction sets is configured based on a virtual remote control interface 210, the virtual remote control interface 210 having exactly or substantially the same key layout as the key region 110 of the remote control 10.

The identical key layout means that: the number of virtual keys on the virtual remote controller interface 210 is identical to the number of keys in the key area 110 of the remote controller 10, and the distribution, arrangement and relative position relationship between the virtual keys on the virtual remote controller interface 210 and the keys in the key area 110 of the remote controller 10 are identical.

The substantially same key layout means that: the number of virtual keys on the virtual remote control interface 210 is substantially the same as the number of keys in the key region 110 of the remote control 10, and/or the distribution, arrangement, and relative position relationship of the virtual keys on the virtual remote control interface 210 and the keys in the key region 110 of the remote control 10 are substantially the same. Including, for example, one or more of the following: the number of virtual keys on the virtual remote control interface 210 is slightly more than the number of keys in the key region 110 of the remote control 10, e.g., the difference is in the range of 20%, preferably 15%, more preferably 10%, as shown in fig. 7; the number of virtual keys on the virtual remote control interface 210 is slightly less than the number of keys in the key region 110 of the remote control 10, e.g., the difference is in the range of 20%, preferably 15%, more preferably 10%, as shown in fig. 8; the distribution, arrangement, and relative position relationship of the virtual keys on the virtual remote controller interface 210 and the keys in the key region 110 of the remote controller 10 are close to each other only by a small amount, as shown in fig. 9 and 10. At this time, it is necessary that the sub-set 115 of one key selected from the key area 110 of the remote controller 10 includes most of the keys, and the sub-set 215 of one virtual key selected from the virtual remote controller interface 210 includes most of the virtual keys, so that the sub-set 115 of keys and the sub-set 215 of virtual keys are the same in terms of number, distribution, arrangement and relative position, as shown in fig. 9 and 10. The majority of keys is for example a number of keys of more than 50%, preferably 60%, more preferably 70%.

Preferably, the set of remote control instructions includes the functions of all virtual keys on the virtual remote control interface and their corresponding remote control signals.

Preferably, the set of remote control instructions includes functions of a portion of virtual keys on the virtual remote control interface and their corresponding remote control signals.

Optionally, the processor 12 is further configured to receive an instruction from the smart device 20, and delete one or more sets of remote control instructions stored in the memory 14 according to the instruction, or adjust the sequence of sequential and cyclic switching according to the unique switching key 112, or adjust the correspondence between the plurality of switching keys 112a to 112d, or the like.

Third, the processor 12 is configured to cycle through the sets of remote control instruction stored in the memory 14 in sequence in response to the unique switch key 112, or to switch between the sets of remote control instruction stored in the memory 14 in response to the plurality of switch keys 112a to 112 d.

Optionally, the processor 12 is further operable to illuminate the respective indicator lights 120 a-120 d according to the currently loaded set of remote control instruction sets.

Fourth, the processor 12 is used to map the functions of the virtual keys in the currently loaded set of remote control commands and the corresponding remote control signals to the keys at the corresponding positions in the key area 110 of the remote controller 10.

If the virtual remote control interface 210 and the key region 110 of the remote control 10 have the same key layout, the virtual keys and the keys have a one-to-one correspondence, so that the functions of the virtual keys and the corresponding remote control signals can be conveniently mapped to the keys at the corresponding positions respectively.

If virtual remote control interface 210 has substantially the same key layout as key region 110 of remote control 10, then a subset 115 of keys that can be selected in key region 110 of remote control 10 contains most of the keys, and a subset 215 of virtual keys that can be selected on virtual remote control interface 210 contains most of the virtual keys, such that key subset 115 and virtual key subset 215 have substantially the same key layout. At this time, the processor 12 maps the functions of the virtual keys belonging to the virtual key subset 215 and the corresponding remote control signals thereof in the currently loaded set of remote control instruction sets to the keys belonging to the corresponding positions of the key subset 115, respectively.

Fifth, the processor 12 is also responsive to the function keys in the key area 110 to transmit the remote control signals mapped by the activated function keys 110 under the currently loaded set of remote control commands to the outside for controlling the controlled device.

Compared with the existing remote controller, the remote controller provided by the application has the following beneficial technical effects.

First, each time the controlled device is replaced by the existing remote controller, a long time-consuming adaptation process is required. The remote controller does not need to carry out an adaptation process, and can conveniently replace the currently loaded remote control instruction set only by pressing the unique switching key or pressing a plurality of switching keys, thereby being suitable for different controlled devices respectively.

Secondly, a plurality of groups of remote control instruction sets are stored in advance when the existing remote controller is manufactured, and infrared remote control signals can only be learned one by one when the existing remote controller is used. The remote controller of the application can not store any remote control instruction set during manufacturing, can write the remote control instruction set into the remote controller in a whole group during configuration, and can also carry out operations such as deleting, adjusting sequencing, adjusting corresponding relation with a switching key and the like on the stored remote control instruction set.

Thirdly, the remote control instruction set written and stored by the remote controller is configured based on the virtual remote controller interface with the same or similar (approximately same) layout as the key area of the remote controller, so that the remote controller can conveniently map the functions of the virtual keys and the remote control signals thereof to the entity keys at the corresponding positions after each group of remote control instruction sets are loaded.

Please refer to fig. 11, which is a first embodiment of the smart device provided in the present application. The smart device 20 is, for example, a mobile phone, a tablet computer, a computer, etc., and has a smart operating system so that a user can install software or an App (Application program) by himself. The smart device 20 includes a processor 22, a memory 24, a display screen 25, an infrared transceiver unit 26, and a network unit 28. As a variation, the ir transceiver unit 26 may be omitted from the smart device 20 and an ir transceiver accessory 36 may be externally connected, as shown in fig. 12.

The processor 22 is, for example, one or more of MCU, MPU, SoC, CPU.

The memory 24 is a non-volatile memory, such as flash, EEPROM, or the like. The memory is used to store one or more virtual remote control interfaces 210, and one or more sets of remote control instructions. Each virtual remote control interface 210 has the same or substantially the same key layout as the key regions 110 of one or more remote controls 10. Each set of remote control instruction set is made based on a virtual remote control interface 210, and each set of remote control instruction set includes functions of some or all virtual keys on the virtual remote control interface and corresponding remote control signals.

Alternatively, the virtual remote control interface, the remote control instruction set, is stored partially or entirely in a remote server, and is obtained by the smart device 20 accessing the remote server via a network.

The display screen 25 is used for displaying. Preferably, the display screen 25 is a touch screen and is also used as an input device. Alternatively, the smart device 20 may also have or be externally connected to an input device such as a keyboard, mouse, or touch pad.

The infrared transceiver unit 26 or the infrared transceiver assembly 36 is used to transmit and/or receive infrared signals. The intelligent device 20 establishes communication with the infrared transceiver unit 16 of the remote controller 10 through the infrared transceiver unit 26 or the infrared transceiver accessory 36.

The network unit 28 is used for network communication, especially for establishing communication with a remote server, and may be any one or more of a wired network communication unit, a wireless local area network communication unit, and a mobile network communication unit.

Please refer to fig. 13, which shows a second embodiment of the smart device according to the present application. The smart device 20 comprises a processor 22, a memory 24, a display 25, a communication unit 27 and a network unit 28. Compared with the first embodiment of the intelligent device, the second embodiment of the intelligent device omits the infrared transceiving unit 26 or the infrared transceiving accessory 36, and adds the communication unit 27. The communication unit 27 is added for establishing communication with the remote controller 10, for example, when the remote controller 10 has the communication unit 17, the communication unit 27 of the smart device 20 and the communication unit 17 of the remote controller 10 are established. At this time, the communication unit 27 of the smart device 20 and the communication unit 17 of the remote controller 10 are preferably the same type, for example, any one or more of a USB communication unit, a bluetooth low energy communication unit, a zigbee communication unit, a wireless lan communication unit, and a mobile network communication unit.

Preferably, when the communication unit 27 is of the same type as the network unit 28, the communication unit 27 is omitted and the network unit 28 is responsible for establishing communication with the remote controller 10.

In the embodiment of the smart device shown in fig. 11-13, the processor 22 is configured to perform the following operations:

first, the processor 22 is used to determine a virtual remote control interface 210 on the smart device 20.

For example, processor 22 presents on display screen 25 one or more pictures of virtual remote control interface 210, with the user preferentially selecting virtual remote control interface 210 having exactly the same key layout as key region 110 of remote control 10, and less preferably selecting virtual remote control interface 210 having approximately the same key layout as key region 110 of remote control 10; processor 22 determines virtual remote control interface 210 based on the user's selection.

As another example, the processor 22 presents a selection box and/or an input box on the display screen 25 for the user to select and/or input information on the brand, model, appearance, etc. of the remote control 10; then, the processor 22 returns one or more query results from the plurality of virtual remote controller interfaces 210 stored in the memory 24 according to the information selected and/or input by the user, or the processor 22 sends the query results to a remote server through a network to perform the query and obtain the query results, and the query results can be presented on the display screen 25 in a text mode or a picture mode of the virtual remote controller interface 210; the processor 22 or remote server then narrows the query results range of the virtual remote control interface 210 based on further selections, inputs, confirmations or repudiations by the user; finally, the processor 22 determines the virtual remote control interface 210 based on the final query result of itself or the remote server.

For another example, the smart device 20 takes a picture or a video of the remote controller 10 of the user through a picture or a video taking unit that is provided or externally connected with the smart device, and then the processor 22 identifies the key layout of the remote controller 10 based on an image or video analysis technology, or the processor 22 sends the key layout to a remote server through a network to perform image or video analysis and obtain an identification result; then the processor 22 or the remote server preferentially selects the virtual remote controller interfaces 210 with the identical key layout based on the recognition result of the image or the video, and sub-optimally selects the virtual remote controller interfaces 210 with the substantially identical key layout; finally, processor 22 determines virtual remote control interface 210 based on the local selection or the selection of the remote server.

For another example, the intelligent device 20 establishes communication with the remote controller 10, and the processor 22 obtains information such as a brand, a model, an identifier, a serial number, etc. from the remote controller 10; then the processor 22 returns a unique query result from a plurality of virtual remote controller interfaces stored in the memory 24 according to the acquired information of the remote controller 10, or the processor 22 sends the query result to a remote server through a network to query and acquire the unique query result; processor 22 determines virtual remote control interface 210 based on the unique query results.

Second, processor 22 is used to configure a remote control instruction set on smart device 20 according to virtual remote control interface 210. This means that at least one set of remote control instruction sets is selected based on the determined virtual remote controller interface 210 and virtual switch keys, the controlled device desired to be operated, and each set of remote control instruction sets is associated with a different number of activations of a unique virtual switch key 212 or with each of a plurality of virtual switch keys 212a to 212 d. The virtual remote control interface 210 includes at least one virtual switch key 212 for switching the remote control instruction set, and at least one virtual function key for implementing a remote control function of the controlled apparatus.

Referring to fig. 14, a partial structure of the virtual remote control interface 210 shows a first implementation manner of the virtual switch key. The virtual remote control interface 210 includes only one virtual switch key 212 for cycling between sets of remote control commands in sequence. The processor 22 presents a selection box and/or an input box on the display screen 25, and the user selects and/or inputs the information of the type, brand, model and the like of the controlled device which the unique virtual switch key 212 wants to control at different triggering times; then the processor 22 returns one or more query results from the multiple sets of remote control instruction sets stored in the memory 24 according to the information selected and/or input by the user, or the processor 22 sends the query results to a remote server through the network to perform the query and obtain the query results; the processor 22 or remote server then narrows the query result range according to further selections, inputs, confirmations or denials of the user until finally determining the unique set of remote control instruction sets corresponding to the unique virtual switch key 212 at different triggering times.

Referring to fig. 15, it is a partial structure of the virtual remote control interface 210, showing a second implementation manner of the virtual switch key. The virtual remote control interface 210 includes a plurality of virtual switch keys, each of which is used to switch to a corresponding set of remote control command sets, schematically illustrated as 4 virtual switch keys 212a to 212d in fig. 14. When the virtual switch key one 212a is triggered, the processor 22 repeats the above process of determining the remote control instruction set, and corresponds the finally determined set of remote control instruction set with the virtual switch key one 212 a. When the second virtual switch key 212b is triggered, the processor 22 repeats the above process of determining the remote control instruction sets, and corresponds the finally determined set of remote control instruction sets to the second virtual switch key 212 b. By analogy, the virtual switch keys 212a to 212d correspond to a group of remote control command sets respectively.

When the processor 22 determines a set of remote control command sets for a determined one of the virtual remote control interfaces 210 at different triggering times of the unique virtual switch key 212 or corresponding to a plurality of virtual switch keys 212a to 212d, respectively, the configuration of the remote control command set is completed. At this time, each configured set of remote control commands typically includes the functions of all the virtual keys of the virtual remote control interface 210 and the remote control signals thereof. If some of the virtual keys are not defined in the configured set of remote control commands, the undefined virtual keys may be ignored or optionally customized by the user. Alternatively, even the defined virtual keys may be modified by the user.

Optionally, processor 22 is used to supplement or modify the configured virtual remote control interface 210 on smart device 20. This includes any one or more of the following: adding functions and remote control signals thereof to the virtual keys which are not configured with functions and remote control signals thereof; the virtual keys for the configured function and its remote control signal modify the function and/or remote control signal. For example, processor 22 presents on display screen 25 a configured virtual remote control interface 210 in which some or all of the virtual keys have been assigned functions and their remote control signals by the determined remote control instruction set. Once an undefined or defined virtual key is triggered, the processor 22 selects a box and/or an input box on the display 25, and a new function of the triggered virtual key is selected and/or input by the user; the processor 22 then saves the new function for the triggered virtual key according to the information selected and/or input by the user, and automatically generates and saves the corresponding remote control signal according to the information of the type, brand, model, etc. of the controlled device.

Third, the processor 22 is used to establish communication with a remote server, which is implemented by the network element 28.

Fourth, the processor 22 is used to establish communication with the remote control 10, which is achieved by the infrared transceiver unit 26 or the infrared transceiver assembly 36 or the communication unit 27.

Fifth, processor 22 is configured to send one or more configured sets of remote control commands to remote control 10 based on a virtual remote control interface 210 having exactly or substantially the same key layout as key region 110 of remote control 10.

Optionally, the processor 22 further sends an instruction to the remote controller 10, which is used to instruct the remote controller 10 to delete one or more sets of remote control instruction stored in the memory 14, or adjust the sequence of sequential and cyclic switching according to the unique switching key 112, or adjust the corresponding relationship between the plurality of switching keys 112a to 112d, etc.

When the key area of the physical remote controller comprises a plurality of switching keys, the virtual remote controller interface also comprises a plurality of virtual switching keys with corresponding quantity, and each group of remote control instruction set corresponds to each virtual switching key at the moment, and corresponds to each switching key after being written into the physical remote controller.
