Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, a television peripheral (e.g., a CEC device) basically has a dedicated remote controller, and when controlling the television peripheral, the dedicated remote controller corresponding to the television peripheral can be directly used to control the television peripheral. For example, the DVD device has a corresponding DVD remote controller, and when the DVD device is playing, the DVD device can be directly operated by using the DVD remote controller. However, when a user operates the external television equipment, the user needs to take the corresponding dedicated remote controller to realize the operation, which obviously brings inconvenience to the user. Although the existing tv remote controller can perform traditional operation control on the external device of the tv, such as pause, play, go out of the warehouse, previous song, next song, stop, etc., for some advanced key functions, such as Settings, PvrList, Guide, etc., some keys need to be customized on the tv remote controller to realize the control on the external device of the tv, and the corresponding menu needs to be called to perform operation using the customized keys during operation. Therefore, the existing motor remote controller can not use the native key (the key value of the key is the native key of the system) to realize the control of the external equipment of the television.
In order to solve the above problem, in the embodiments of the present invention, after receiving a key instruction of a television remote controller, analyzing the received key instruction and determining whether the key instruction meets a preset condition, where the preset condition is used to determine whether the key instruction is an instruction for operating an external device of a television, that is, to determine whether the key instruction sent by a user through the television remote controller is used to control the external device of the television or to control the television. Specifically, the preset conditions in this embodiment include: the key instruction is a preset instruction (such as a long-time pressing instruction or a continuous clicking instruction). And if the key instruction received by the television is a preset instruction, judging that the key instruction meets a preset condition, namely judging that the key instruction is an instruction for controlling the television external equipment connected with the television. Alternatively, the preset condition in this embodiment may also be set as: the key instruction comprises customized key request information. The customized key request information is used for driving the television to perform key value conversion after receiving the key instruction, and if key value conversion is required, the key instruction is an instruction for controlling external equipment of the television. Therefore, the embodiment can judge whether the purpose of the key instruction is used for controlling the external equipment of the television through the preset condition. And because the key instruction is sent out by the television remote controller, the original key value in the key instruction can only be used for controlling the television and cannot be used for controlling the television external equipment connected with the television. Therefore, in order to control the external television device by the key instruction, the embodiment of the present invention needs to convert a native key value in the key instruction into a target key value that can be recognized by the external television device, and after the conversion is completed, the converted target key value is sent to the external television device, and the external television device can execute a corresponding operation after receiving the target key value, thereby controlling the external television device. Therefore, in the embodiment of the invention, the television remote controller is not provided with the customized keys, but converts the native key values in the key instructions sent by the native keys of the television remote controller, so that the converted key values are used for controlling the external equipment of the television, namely, when a user uses the television remote controller, the external equipment of the television can be controlled through the television remote controller, and the television can be controlled through the television remote controller.
For example, when a user presses a "set key" on a television remote controller, the "set key" sends a key instruction, and the key instruction includes a native key value of the "set key". After the television receives the key instruction, the key instruction is analyzed first to judge whether the preset condition in the embodiment is met, if the preset condition is met, the purpose of the key instruction is to control the DVD device connected with the television, and if the key instruction does not meet the preset condition, the key instruction is judged to be used for controlling the television. When the key instruction sent by the 'set key' is judged to be used for controlling the DVD device, the key value in the key instruction needs to be converted into the key value which can be identified by the DVD device, and the converted key value is sent to the DVD device, and the DVD device opens the set page in the DVD device after receiving the converted key value. Similarly, the user can press other keys on the television remote controller and perform corresponding control on the DVD device through key value conversion.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides a method for controlling an external device of a television, and specifically as shown in fig. 1, the method includes the following steps:
step S100, when a key instruction sent by a television remote controller is received, whether the key instruction meets a preset condition is judged.
In this embodiment, since the television remote controller is used for controlling the television, a key instruction sent by a user through the television remote controller is firstly received by the television, and after the television receives the key instruction, the received key instruction is firstly analyzed, so that the purpose of analysis is to judge whether the key instruction is an instruction for controlling the television or an instruction for controlling a television external device connected to the television. The specific judgment mode is that a preset condition is set, whether the key instruction meets the preset condition is judged by analyzing the key instruction, if the preset condition is met, the key instruction is used for controlling the external equipment of the television, and if the preset condition is not met, the key instruction is not used for controlling the external equipment of the television, namely, the key instruction is used for controlling the television.
The preset condition is used for judging whether the key instruction is an instruction for operating the external television equipment, namely, the preset condition is used for judging whether the key instruction sent by the user through the television remote controller is used for controlling the external television equipment or the television. Specifically, the preset conditions in this embodiment include: the key instruction is a preset instruction (such as a long-time pressing instruction or a continuous clicking instruction). And if the key instruction received by the television is a preset instruction, judging that the key instruction meets a preset condition, namely judging that the key instruction is an instruction for controlling the television external equipment connected with the television. Alternatively, the preset condition in this embodiment may also be set as: the key instruction comprises customized key request information. The customized key request information is used for driving the television to perform key value conversion after receiving the key instruction, and if key value conversion is required, the key instruction is an instruction for controlling external equipment of the television.
In an implementation manner, the preset instruction in this embodiment may be a long-press instruction, where the long-press instruction is the key instruction sent after the time that the key on the television remote controller is pressed exceeds a preset time period, that is, if the time that the user presses a certain key on the television remote controller exceeds the preset time period, the key instruction sent by the key is the long-press instruction. And if the key instruction received by the television is a long-time pressing instruction, judging that the key instruction meets a preset condition, namely judging that the key instruction is an instruction for controlling the television external equipment connected with the television.
Specifically, as shown in fig. 2, the manner of determining whether the key instruction is a long-press instruction in this embodiment includes the following steps:
step S101, acquiring signal data in the key instruction, and extracting the moment when the television remote controller starts to send signals and the moment when the television remote controller stops sending signals from the signal data;
step S102, acquiring the total time length of the signal transmitted by the television remote controller according to the time when the television remote controller starts to transmit the signal and the time when the television remote controller stops transmitting the signal, and comparing the total time length with the preset time length;
and S103, if the total duration is greater than the preset duration, judging that the key instruction is a long-press instruction.
In this embodiment, after receiving a key instruction sent by a user through a certain key on a television remote controller, the television analyzes the key instruction, and then acquires signal data in the key instruction. The signal data is data transmitted to the television after a native key on the television remote controller is pressed, and includes data such as a time when a signal starts (i.e., a time when the television remote controller starts to transmit a signal), a time when the signal ends (i.e., a time when the television remote controller stops transmitting the signal), and signal data (e.g., a native key). In order to judge whether the key instruction is a long-press instruction, whether the total time for pressing the native key on the television remote controller by the user exceeds a preset time is judged. Therefore, in this embodiment, the time when the television remote controller starts to send a signal and the time when the television remote controller stops sending the signal are extracted from the signal data, since the television remote controller will send a signal to the television set after a certain native key is pressed, and will stop sending the signal to the television set after a certain native key is released, it is obvious that the time when the television remote controller starts to send a signal is extracted from the signal data, that is, the time when a user starts to press a certain native key on the television remote controller, and the time when the television remote controller stops sending a signal is extracted, that is, the time when a user releases a certain native key on the television remote controller. And then obtaining the total time length of the signal sent by the television remote controller (namely the total time length of the original key on the television remote controller pressed by the user) according to the time when the television remote controller starts to send the signal and the time when the television remote controller stops sending the signal, then comparing the total time length with a preset time length (such as 2s), if the total time length is greater than the preset time length, judging that the key instruction is a long-press instruction, and further judging that the key instruction meets a preset condition.
For example, the user presses a "set key" on the tv remote control, and issues a key command a. After receiving the key instruction A, the television analyzes the key instruction A to acquire signal data in the key instruction A. Then, the time when the television remote controller starts to transmit signals is 9 o 'clock 13 min 24 sec (the time when the user presses the "set key") and the time when the television remote controller stops transmitting signals is 9 o' clock 13 min 27 sec (the time when the user releases the "set key") are extracted from the signal data. Therefore, the total duration of the signal sent by the television remote controller is 3 seconds (namely the total duration of pressing the 'setting key'), then the total duration of 3 seconds is compared with the preset duration of 2 seconds, and when the total duration is judged to be greater than the preset duration, the key instruction sent by the 'setting key' is judged to be a long-time pressing instruction, and the key instruction is further judged to meet the preset condition.
Certainly, the preset instruction in this embodiment may also be a continuous click instruction, for example, when it is detected that the native key on the television remote controller is continuously pressed twice, the key instruction is the continuous click instruction, and therefore it is determined that the key instruction meets the preset condition, that is, it is determined that the key instruction is an instruction for controlling the external television device connected to the television.
Further, the preset conditions in this embodiment may also be set as: the key instruction comprises customized key request information. The customized key request information is used for driving the television to perform key value conversion after receiving the key instruction, and if key value conversion is required, the key instruction is an instruction for controlling external equipment of the television. Therefore, after the key instruction is analyzed, if customized key request information exists in the key instruction, it is determined that the preset condition is met in the key instruction, that is, it is determined that the key instruction is an instruction for operating and controlling a television external device connected to the television.
Specifically, as shown in fig. 3, the manner for determining whether the key instruction includes the customized key request information in this embodiment includes the following steps:
step S110, when a key instruction sent by a television remote controller is received, signal data in the key instruction is obtained;
step S120, determining a customized key request identifier from the signal data, and identifying and confirming the customized key request identifier searched out to confirm whether the customized key request information exists in the key instruction.
In this embodiment, after the television receives a key instruction sent by a user through a certain native key on the television remote controller, the key instruction is analyzed, and then signal data in the key instruction is obtained. The signal data is then searched for a customized key request identifier that reflects whether customized key request information is present in the signal data. That is, if the customized key request flag is present, it indicates that the customized key request information is present in the signal data. In one embodiment, the customized key request information in this embodiment is added to the key command via a specific key on the tv remote controller. That is, when the user sends the key command through the television remote controller, the user can simultaneously press a preset specific key, that is, customized key request information can be added to the key command and sent to the television together. In this embodiment, after the customized key request identifier is searched, the searched customized key request identifier is identified and confirmed, so as to prevent misjudgment caused by identification error, and thus determine whether the customized key request information exists in the key command. In an implementation manner, the customized key request identifier in this embodiment may be a character identifier, for example: the character identification customizations may be set as the customized key request identification.
For example, the user presses a "set key" on the tv remote control, and issues a key command a. After receiving the key instruction A, the television analyzes the key instruction A to acquire signal data in the key instruction A. And then searching the signal data, searching a preset character identifier, and if the character identifier is searched, indicating that a customized key request identifier exists in the signal data, and further judging that the key instruction meets a preset condition.
Further, after it is determined that the key instruction meets the preset condition, it is determined that the key instruction is used for controlling the external television device, and therefore a native key value in the key instruction needs to be converted. Executing step S200, if the key instruction meets the preset condition, obtaining a native key value in the key instruction, and converting the native key value into a target key value that can be recognized by the television peripheral device.
In this embodiment, the received native key value in the key instruction is used for controlling the television, and it is found through the analysis of the key instruction that the key instruction is used for controlling the external television device connected to the television, and therefore the native key value in the key instruction needs to be converted, and the conversion aims at converting the native key value in the key instruction into a target key value which can be recognized by the external television device, so that the external television device can perform corresponding operations.
Specifically, the preset conditions set in the embodiment of the present invention have two different forms, that is, the manner of determining whether the key instruction satisfies the preset conditions is different, so the manner of key value conversion is also different. As shown in fig. 4, the key value conversion process when the key instruction is a preset instruction (such as a long press instruction or a continuous click instruction) includes the following steps:
step S201, acquiring a standard protocol of the external equipment of the television, and acquiring a key value data conversion protocol table from the standard protocol, wherein the key value data conversion protocol table comprises key value conversion requirements among keys with the same function of different remote control equipment;
step S202, according to the key value data conversion protocol table, converting the native key value in the key instruction into the target key value.
In this embodiment, if it is determined that the key instruction is a preset instruction, that is, it is determined that the key instruction meets the preset condition, it is determined that the key instruction is used for controlling the external device of the television. And at the moment, the standard protocol of the external television equipment is obtained from the external television equipment, and the key value data conversion protocol table is obtained from the standard protocol. The key value data conversion protocol table is used for guiding a user to perform key value conversion and comprises a special remote controller of the external television equipment and a key value conversion requirement between keys with the same function on the remote controller of the television. For example, key value conversion of the same function keys between the television remote controller and the special remote controller of the external equipment of the television. Because the key value conversion protocol table has a key value conversion relationship, namely the key value conversion relationship between the original key value of the original key on each television remote controller and the target key value of the target key of the exclusive remote controller of the external equipment, the original key value can be converted into the target key value according to the key value conversion relationship so as to realize the identification by the external equipment of the television. In an embodiment, the key-value conversion relationship may be an operation manner determined based on the key-value data conversion protocol table, and the key-value conversion is implemented by the operation manner. Therefore, after the key value data conversion protocol table is obtained, the received native key value in the key instruction is converted into the target key value according to the key value data conversion protocol table, and the function of the converted target key value to the external television device is the same as the function of the native key value to the television device, that is, the operation functions corresponding to the two key values to the respective devices are the same. Therefore, in the embodiment, the key value conversion only converts the original key value originally used for operating the television into the target key value which can be identified by the external equipment of the television, the function of the key value conversion is not changed, and only the object on which the original key value is to be acted is converted into the external equipment of the television from the original television.
For example, after the television receives a key instruction a sent by a user through a "set key" on the television remote controller, and it is already determined that the key instruction a is a preset instruction, a key value data conversion protocol table is obtained from a DVD device (in this example, the television external device is a DVD device), where the key value data conversion protocol table includes a key value conversion requirement between a dedicated remote controller of the DVD device and a same function key of the television remote controller. Therefore, the key value data conversion protocol table can be searched, the original key value of the setting key on the television remote controller is converted into the key value conversion requirement of the key value corresponding to the setting key on the exclusive remote controller of the DVD equipment, and the original key value of the setting key on the television remote controller is converted into the key value corresponding to the setting key on the exclusive remote controller of the DVD equipment according to the key value conversion requirement, so that the DVD equipment can execute corresponding operation through the converted key value.
Further, as shown in fig. 5, the key value conversion process when the key instruction includes the customized key request message includes the following steps:
step S310, if the customized key request information exists in the key instruction, analyzing the key instruction to obtain a native key value in the key instruction;
step S320, acquiring a preset mapping relation table, and inquiring a target key value which has a mapping relation with the native key on the television remote controller from the mapping relation table; (ii) a
And step S330, converting the native key value into the target key value according to the mapping relation table.
In this embodiment, if it is determined that the key instruction has the customized key request information, that is, it is determined that the key instruction meets the preset condition, it is determined that the key instruction is used for controlling the external television device. And adjusting the original key value originally corresponding to the key instruction, and converting the original key value into a target key value so as to be identified by the external equipment of the television. Specifically, after the key instruction is judged to meet the preset condition, a preset mapping relation table is obtained, and a target key value having a mapping relation with a native key on the television remote controller is inquired from the mapping relation table; and finally, converting the native key value into the target key value according to the mapping relation table so as to realize the identification of the native key value by the external television equipment.
In an implementation manner, the mapping relationship table in this embodiment is preset, and the mapping relationship table is obtained by adjusting the original key value mapping relationship in the television remote controller. For example, the mapping relationship table may be generated by performing data initialization on the original key value mapping relationship in the television remote controller, where the data initialization is to reset data, and reconstructing the key value mapping relationship in the television remote controller. Or the converted target key value can replace a native key value in the original key value mapping relation in the remote controller to generate the mapping relation table.
In an embodiment, for the construction manner of the mapping relationship table, in this embodiment, the television firstly obtains a configuration file of the external television device, where the configuration file stores mapping files of mapping relationships between each native key in the external television device (i.e., a target key on a dedicated remote controller of the external television device) and a target key corresponding to each native key. The purpose to be achieved by the embodiment of the invention is to control the external television equipment through the native keys on the remote television controller, the native key values corresponding to the keys on the remote television controller cannot control the external television equipment, and the target key values of the external television equipment correspond to the native keys on the dedicated remote controller of the external television equipment. Based on this, in this embodiment, after the mapping file is obtained, the mapping relationship in the mapping file is adjusted, and specifically, according to a corresponding relationship between a target key of the external television device having the same function and a native key on the television remote controller, a mapping relationship manner is added or an existing mapping relationship is adjusted, so that a mapping relationship table of a native key used for sending the key instruction on the television remote controller and a target key value corresponding to a target key having the same function as the native key is constructed. The mapping relation table stores the corresponding relation of the target key with the same function as the original key on the television remote controller on the television external device and the target key value corresponding to the target key; therefore, the native key value of the native key on the television remote controller can be converted into the target key value key corresponding to the target key with the same function as the native key on the external equipment of the television according to the mapping relation, and the key value conversion is completed. That is to say, in this embodiment, a mapping relationship is established between native keys on a television remote controller and target key values, the target key values correspond to target keys on the external television device, and the functions of the native keys and the target keys are the same, so that a user can directly operate the native keys on the television remote controller during operation, and then the target key values mapped with the native keys on the television remote controller are sent to the external television device through the established mapping relationship table, thereby controlling the external television device.
For example, when the mapping relationship table is constructed, the configuration file is obtained from a DVD device (in this example, the television external device is the DVD device). Then, a mapping file is obtained from the configuration file, and each target key of the dedicated remote controller of the DVD device and a target key value corresponding to each target key are stored in the mapping file, for example, a "set key" on the dedicated remote controller corresponds to a 101 key value, and a "menu key" on the dedicated remote controller corresponds to a 102 key value. If a key instruction A is sent by a 'set key' on a television remote controller, and a 'set key' of a dedicated remote controller of DVD equipment with the same function as the 'set key' on the television remote controller is obtained from a mapping file, the 'set key' on the television remote controller corresponds to a 101 key value, and because the 'set key' on the television remote controller and the 'set key' of the dedicated remote controller of the DVD equipment have the same function, a mapping relation between the 'set key' (namely a native key) on the television remote controller and the 101 key value (namely a target key value) can be established. In the same way, the mapping relation between other native keys on the television remote controller and the target key values of the target keys with the same function on the exclusive remote controller of the DVD equipment can be constructed, so that a mapping relation table is generated. After the television receives a key instruction A sent by a user through a 'set key' on a television remote controller and the key instruction A is judged to comprise customized key request information, the 'set key' on the television remote controller is mapped to a 101 key value (namely a target key value corresponding to the 'set key' of a special remote controller of the DVD device) according to the mapping relation table, and then the mapped 101 key value is sent to the external equipment of the television so as to control the external equipment of the television.
In an embodiment, the mapping relationship table in this embodiment is preset and stored, so that when a user operates a television external device through a television remote controller later, the mapping relationship table can be directly called, and a target key value corresponding to a key of the user on the television remote controller is directly found out, thereby operating CEC.
Further, step S300, the target key value is sent to the external television device to control the external television device.
In specific implementation, after the native key value in the key instruction is converted into the target key value, the target key value can be sent to the external television equipment, and the external television equipment executes corresponding operation after receiving the target key value.
In an embodiment, if the key instruction does not satisfy the preset condition, that is, the key instruction is neither a preset key instruction nor customized key request information, the television is directly controlled according to a native key value in the key instruction. In other words, when the key instruction does not satisfy the preset condition, it indicates that the key instruction is not used for operating the external equipment of the television and is used for operating the television, so that the television is directly controlled to execute corresponding operation.
According to the control method of the external television equipment, provided by the embodiment of the invention, the key instruction can be analyzed after the key instruction sent by the remote controller of the television is received, and when the key instruction meets the preset condition, the key instruction is considered to be used for controlling the external television equipment, so that a primary key value in the key instruction needs to be converted into a target key value which can be identified by the external television equipment, and the converted target key value is sent to the external television equipment. And because the function of the target key value is the same as that of the original key value, the external television equipment can execute corresponding operation after receiving the target key value, so that the external television equipment can be controlled through the original key on the television remote controller, a customized key is not required to be arranged on the television remote controller to specially operate the external television equipment, and convenience is provided for the use of a user.
