Detailed Description
Compared with the low-version Bluetooth protocol, the Bluetooth 5.0 protocol has obvious advantages in the aspects of transmission efficiency, transmission distance, power consumption and the like.
However, most smart tvs currently support only a few fixed low-version bluetooth protocols, but not other versions of bluetooth protocols, such as bluetooth 5.0 protocol, resulting in limited performance of the smart tv.
In view of the above problems, an embodiment of the present invention provides a terminal adapter, where the terminal adapter has a USB interface, a bluetooth communication module, and a data processing module, and on one hand, the terminal adapter can be connected to a terminal such as a smart television through the USB interface, and on the other hand, the terminal adapter can be connected to other bluetooth devices through the bluetooth communication module, and can be indirectly connected to the terminal such as the smart television regardless of a protocol version supported by other bluetooth devices, so as to effectively improve the performance of the terminal such as the smart television.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a terminal adapter 10, where the terminal adapter 10 may include: the USB interface 11, the Bluetooth communication module 12 and at least one data processing module 131-13M. M is a positive integer greater than or equal to 1.
The USB interface 11 is adapted to receive USB data, or send first information to be transmitted using a USB protocol;
the bluetooth communication module 12 is adapted to receive bluetooth data, or send a second message to be transmitted using a bluetooth protocol;
the data processing modules 131-13M are connected with the Bluetooth communication modules 121-12N and the USB interface 11, and are suitable for acquiring first information to be transmitted from received USB data and sending the first information to be transmitted to the Bluetooth communication module 12, or acquiring second information to be transmitted from the received Bluetooth data and sending the second information to be transmitted to the USB interface 11.
In the implementation, the terminal adapter 10 can be connected to the terminal through the USB interface 11 on the one hand, and can be connected to other bluetooth devices through the bluetooth communication module 12 on the other hand, so that the functions of the terminal can be expanded, and the performance of the terminal can be improved.
In the embodiment of the present invention, the terminal adapter 10 not only supports data transmission from other bluetooth devices to the terminal, but also supports data transmission from the terminal to other bluetooth devices, that is, the terminal adapter supports bidirectional data transmission.
Specifically, the terminal may connect to the USB interface 11 of the terminal adapter 10 through its own USB interface, and transmit USB data to the terminal adapter 10. The USB interface 11 sends the received USB data to the corresponding data processing module, the data processing module decodes the USB data to obtain corresponding data content, i.e. the first information to be transmitted, and then sends the first information to be transmitted to the corresponding bluetooth communication module, and the bluetooth communication module encapsulates the first information to be transmitted into a corresponding bluetooth data packet and sends the corresponding bluetooth data packet to the corresponding bluetooth device.
The bluetooth device can perform bluetooth pairing connection with the bluetooth communication module of the terminal adapter 10 through the bluetooth communication module of the bluetooth device, and then send corresponding bluetooth data to the bluetooth communication module of the terminal adapter 10. The bluetooth communication module of the terminal adapter 10 sends the received bluetooth data to the data processing module, the data processing module obtains the data content, that is, the second to-be-transmitted information, from the data content, and then sends the second to-be-transmitted information to the USB interface 11, and the USB interface 11 packages the second to-be-transmitted information into a corresponding USB data packet and sends the corresponding USB data packet to the terminal.
In an implementation, in order to improve the performance of the terminal, the bluetooth protocol version supported by the bluetooth communication module 12 may be higher than the bluetooth protocol version supported by the terminal. For example, when the bluetooth protocol version supported by the terminal is lower than the bluetooth 5.0 protocol, the bluetooth protocol version supported by the bluetooth communication module 12 may be the bluetooth 5.0 protocol, so that other bluetooth devices with low power consumption, longer transmission distance and higher transmission efficiency may be introduced to the terminal through the terminal adapter 10, thereby improving the performance of the terminal.
In a specific implementation, the bluetooth communication module 12 supports simultaneous connection of a plurality of bluetooth devices, that is, the terminal adapter 10 may connect a plurality of bluetooth devices through the bluetooth communication module, and the number of the connected bluetooth devices is not limited, and may be only one, or may be more than two.
For example, the bluetooth communication module 12 may perform bluetooth connection with N bluetooth devices, where N is a positive integer, that is, the terminal adapter 10 may perform bluetooth connection with N bluetooth devices simultaneously, which is equivalent to that the terminal may be externally connected with N bluetooth devices simultaneously.
In a specific implementation, only one data processing module, that is, M is 1, may be provided in the terminal adapter 10, where the bluetooth communication modules 12 are all connected to the same data processing module 131, and data transmission between the bluetooth communication module 12 and the USB interface 11 is all through the data processing module 131.
Specifically, for the USB data received by the USB interface 11, the first information to be transmitted is acquired from the received USB data by the data processing module 131 and sent to one or more of the bluetooth communication modules 12. For the bluetooth data received by the bluetooth communication module 12, the data processing module 131 obtains the second to-be-transmitted information from the received bluetooth data and sends the second to-be-transmitted information to the USB interface 11.
In another embodiment, in order to further improve the data transmission efficiency and reduce the time delay, more than two data processing modules may be disposed in the terminal adapter 10, and the data processing modules 131 to 13M and the bluetooth communication module 12, that is, M is greater than or equal to 2.
At this time, the bluetooth communication module 12 performs data transmission with the USB interface 11 through different data processing modules, respectively, so as to implement data transmission between different bluetooth devices and terminals. For example, the bluetooth communication module 12 performs data transmission with the USB interface 11 through the data processing module 132, and performs data transmission with the USB interface 11 through the data processing module 133. Therefore, when the bluetooth communication module 12 simultaneously performs data transmission with USB data, the data processing modules uniquely corresponding to each can synchronously process corresponding data, thereby reducing data processing delay.
In specific implementation, the bluetooth device connected to the bluetooth communication module 12 may be a bluetooth microphone, a bluetooth remote controller, a bluetooth speaker, or a bluetooth headset. One or more of the above-mentioned bluetooth devices may be simultaneously connected with the terminal through the terminal adapter 10.
Taking the terminal as an example of the smart television, the bluetooth microphone is connected with the smart television through the terminal adapter 10, so that the karaoke function on the smart television can be realized, and a corresponding karaoke function module does not need to be arranged in the smart television, so that the audio function of the smart television can be expanded at lower cost.
When passing through terminal adapter 10 with bluetooth speaker or bluetooth headset and being connected with the smart television, can pass through the USB interface broadcast with the sound of smart television, when the bluetooth protocol version that bluetooth speaker or bluetooth headset supported is higher, can be so that the tone quality of broadcast is better, and transmission distance is farther, and the consumption is lower, and the time delay is also shorter.
When the bluetooth remote controller and the terminal adapter 10 are connected with the smart television, the second information to be transmitted can be set as a voice search instruction, that is, the user inputs the voice search instruction through the bluetooth remote controller, and a voice search function can be added on the smart television, so that the smart television is more intelligent. Certainly, the user may also input other information through the bluetooth remote controller, and then the terminal adapter 10 outputs a corresponding Human Interface Device (HID) control command to the smart television, so as to control the smart television.
In general, the USB data output by the smart television may include identification information of a target bluetooth device, and the number of the identification information of the target bluetooth device may be only one, so that the audio data output by the smart television may be sent to a bluetooth device corresponding to the identification information of the target bluetooth device. Specifically, the USB interface 11 may send the USB data to the corresponding data processing module according to the identification information of the target bluetooth device carried in the USB data, and then the data processing module sends the acquired first information to be transmitted to the corresponding bluetooth function module, and further sends the first information to be transmitted to the corresponding bluetooth device.
In an embodiment of the present invention, through the terminal adapter 10, the audio of the smart television can also be simultaneously sent to multiple bluetooth devices, so as to implement the function of play-multiple-pair-1.
Specifically, the USB data output by the smart television may include identification information of more than two target bluetooth devices, and the identification information of more than two target bluetooth devices corresponds to different bluetooth devices respectively. The USB interface 11 sends the USB data to the corresponding data processing modules based on the identification information of the two or more target bluetooth devices, and then the data processing modules send the acquired first information to be transmitted to the corresponding bluetooth function modules, and further send the first information to the bluetooth function modules.
In another embodiment of the present invention, in order to implement the function of audio data 1 for pair-multi-play of the smart tv, data sharing indication information may be set in the USB data. The data sharing indication information is used for indicating whether the Bluetooth equipment connected with the terminal adapter shares the first information to be transmitted.
And when the data sharing indication information indicates that the connected Bluetooth equipment shares the first information to be transmitted, the first information to be transmitted is sent to the Bluetooth function module and then transmitted to each Bluetooth equipment, so that the function of sharing the audio data by all the Bluetooth equipment is realized.
When the data sharing indication information indicates that the connected bluetooth devices do not share the first information to be transmitted, the USB data may further include identification information of more than one target bluetooth device, so that only the first information to be transmitted may be sent to the bluetooth device corresponding to the identification information of the target bluetooth device.
As can be seen from the above, the terminal adapter 10 in the embodiment of the present invention can implement audio function expansion of terminals such as a smart television at a lower cost, and improve the performance of terminals such as a smart television.
Referring to fig. 2, an embodiment of the present invention further provides a communication system 20, where the communication system 20 may include a terminal 21, a bluetooth device, and the terminal adapter 10 in any of the above embodiments. The terminal adapter 10 may be connected to the terminal 21 through the USB interface and to the bluetooth device through the bluetooth communication module.
In a specific implementation, the number of the bluetooth devices is not limited, and the bluetooth device may be a bluetooth microphone 221, a bluetooth remote controller 222, a bluetooth speaker 223, or a bluetooth headset 224. Of course, other bluetooth devices are also possible, and are not limited herein.
The terminal 21 has its own USB interface, and is connected to the terminal adapter 10 via its own USB interface. The terminal adapter 10 can register and generate an audio input interface and an audio output interface in the terminal 21, so that the audio of the terminal 21 can be transmitted to the bluetooth speaker 223 or the bluetooth headset 224 through the terminal adapter 10 for playing. In addition, the terminal adapter 10 can be connected to the bluetooth remote controller 222, receive the control command sent by the bluetooth remote controller 222, decode the control command, and send the decoded control command to the terminal 21 through the USB interface.
In an embodiment, the terminal adapter 10 may further send the audio data of the terminal 21 to a plurality of bluetooth devices simultaneously, so as to implement a function of sharing audio by multiple users.
In the embodiment of the invention, the terminal can be an intelligent household device such as an intelligent television. It is understood that the specific device of the terminal is not intended to limit the present invention, and is within the scope of the present invention.
As can be seen from the above, in the communication system 20 in the embodiment of the present invention, since the terminal may be connected to the plurality of bluetooth devices through the terminal adapter 10, the audio function of the terminal such as the smart television can be extended, and under the condition that the terminal itself such as the smart television does not support a higher protocol version, the terminal such as the smart television can achieve the characteristic of supporting the higher protocol version, so that the audio function of the terminal such as the smart television can be effectively improved, and the effects of better tone quality, farther transmission, lower power consumption, and shorter delay are achieved.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
