Fig. 1 shows a schematic diagram of a first example communication structure of a wireless audio/video device according to an embodiment of the present application. The wireless audio/video device supports a WiFi-based wireless multimedia transmission protocol. In some embodiments, the WiFi-based wireless multimedia transmission protocol includes any one of DLNA protocol, airPlay protocol, and Miracast protocol, and modified protocols based thereon. The DLNA protocol is proposed by sony, intel, microsoft, etc., and is called DIGITAL LIVING NETWORK ALLIANCE, which enables sharing of photos, videos, and music among electronic products such as mobile phones and tablet computers. The air play protocol is to push audio or video of the iPod, iPhone, iPad and Apple Watch to the controlled device for playing. The Miracast protocol is a Wi-Fi direct based wireless display protocol. The DLNA protocol supports a one-to-one configuration of the sender and the receiver, such as a first earpiece sending to a second earpiece. The AirPlay protocol supports a one-to-many configuration of sender and receiver, such as the smart device sending audio to multiple receiving speakers. The wireless audio/video device can communicate with the intelligent device by using any one of DLNA protocol, airPlay protocol and Miracast protocol and the improved protocol based on the DLNA protocol, airPlay protocol and Miracast protocol, so that the intelligent device can push audio/video data conveniently.

As shown in fig. 1, the wireless audio/video apparatus includes a first wireless audio/video device 110 and a second wireless audio/video device 120 that are grouped and cooperate, the first wireless audio/video device 110 including a first system-on-chip 111 and the second wireless audio/video device 120 including a second system-on-chip 121. The first wireless audio/video device 110 and the second wireless audio/video device 120 may include a pair of ear phones with a first earpiece and a second earpiece, a master slave speaker, etc. Taking the example of a pair of ear phones, the first system-on-chip 111 may be provided in a first ear phone and the second system-on-chip 121 may be provided in a second ear phone.

As shown in fig. 1, the first system on a chip 111 is configured to attempt to connect to the router 130 based on configuration information of the router, the router 130 being required to build a wireless local area network on which the WiFi-based wireless multimedia transmission protocol depends. In some embodiments, the configuration information of router 130 includes a network name and password of router 130. The configuration information of the router 130 may further include information such as a media access control (Media Access Control, abbreviated MAC) address, a key, etc. of the wireless router to be connected. The configuration information through the router 130 enables identification of the router 130 and establishment of a wireless connection with the router 130 during connection of the router 130.

As shown in fig. 1, audio/video data from the smart device 140 or cloud server 150 is received via the router 130 in accordance with the WiFi-based wireless multimedia transmission protocol, with being connected to the router 130. The smart device 140 may be any one of smart electronic devices such as a mobile phone, a notebook computer, a tablet computer, an iPod, a smart watch, and the like. As shown in fig. 1, if the first system on chip 111 can be wirelessly connected to the router 130 by using the configuration information of the router 130, it is indicated that the first system on chip 111 is within the connection range of the router 130, and if the smart device 140 or the cloud server 150 can also be wirelessly connected to the router 130, the audio/video data of the smart device 140 or the cloud server 150 can be sent to the first system on chip via the router 130, so that the first system on chip 111 plays the audio/video. The audio/video data of the smart device 140 or the cloud server 150 may be forwarded directly to the second system-on-chip (not shown in fig. 1) through a router, or may be forwarded by the first system-on-chip through a WiFi connection or a bluetooth connection between the first system-on-chip and the second system-on-chip. Thus, the user can directly enjoy the experience of audio/video push playing of the wireless multimedia transmission protocol based on WiFi in the environment with the router 130.

As shown in fig. 1, in case of being not connected to the router 130, the local first soft access point 112 created according to the configuration information of the router 130 is turned on, and audio/video data from the smart device 140 is directly received via the turned-on first soft access point 112 according to the WiFi-based wireless multimedia transmission protocol; and forwarding the received audio/video data, the second system on chip 121 being configured to: the forwarded audio/video data is received. As shown in fig. 1, the first system on a chip 111 may not be connected to the router 130 because the first system on a chip 111 is not within the connection range of the router 130 or the router 130 is not operational. The first system on a chip 111 opens the local first soft access point 112 created from the configuration information of the connected router 130, which may be pre-created so that it can be opened in time when the router is not connected or the creation and opening process can be performed when the router is not connected. In the process that the first system on chip 111 and the intelligent device 140 are connected with the router 130, the intelligent device 140 stores the configuration information of the router 130, so that the first system on chip 111 can be directly connected with the first soft access point 112 under the condition that the first system on chip 111 is not connected with the router 130, and the intelligent device 140 can be directly connected with the first soft access point 112 in a wireless manner, so that a user does not need to manually input the configuration information of the router 130, and the operation of the user can be facilitated. In the case of a wireless network established by the first soft access point 112, the smart device 140 transmits audio/video data to the first soft access point 112, and the first soft access point 112 transmits audio/video data to the first system on a chip 111. The first on-chip system 111 can receive the audio/video data for playing, and then the audio/video data received by the first on-chip system 111 can be forwarded by the first soft access point 112, or can be forwarded by the first on-chip system 111 to the second on-chip system 121 through bluetooth/WIFI for playing by the second wireless audio/video device 120. In this way, in case the first system on chip 111 cannot connect to the router 130, the use of the WiFi-based wireless multimedia transmission protocol can be supported by the first soft access point 120. The limitation that the router can only be used under the networking of the router is overcome, and the router is convenient for users to use. For example, in the outdoor router-free scenario, audio data can still be pushed to the first earphone through the mobile phone, so that a user can enjoy the experience of listening to music pushed by the mobile phone through the mobile phone outdoors.

As shown in fig. 1, if the first system on chip 111 is not within the connection range of the router 130, the router 130 cannot operate, or is within the range of a new router in a mobile usage scenario, the new router cannot be connected because the first system on chip 111 does not have configuration information of the new router. Therefore, in the mobile usage scenario, the first soft access point 112 can be created by using the configuration information of the connected router, and the router networking is not required to be repeated, so that the experience that the user directly plays the audio/video based on the wireless multimedia transmission protocol of the WiFi is improved. For example, in a mobile car, the intelligent device 140 is a mobile phone, the mobile phone can directly push audio to the pair of ear phones by using the soft access point of the first earphone, the router networking is not required to be repeated, the first earphone is not required to be repeatedly connected, and the mobile use experience is convenient for users.

In some embodiments, the first system-on-chip may include a mobile chip and a WiFi communication module that may convert mobile network signals of the mobile chip into wireless signals by creating a first soft access point. Such as a 4G network signal, is converted to a wireless signal by a first soft access point. Similarly, for the second system-on-chip hereinafter, the mobile chip and the WiFi communication module may be also included to establish the second soft access point and the third soft access point.

The various components in the present application, such as the classical bluetooth communication module, the LE Audio communication module, the codec, etc., may be implemented by an SOC (system on chip), including a first system on chip and a second system on chip. For example, various RISC (reduced instruction set computer) processors IP purchased from ARM company or the like may be used as processors of the SOC to execute the corresponding functions, and may be implemented as an embedded system. In particular, there are many modules on the commercially available modules (IP), such as, but not limited to, memory, various communication modules, codecs, buffers, and the like. Other devices such as an antenna and speaker may be external to the chip. Users can implement various communication modules, codecs, etc. by constructing ASICs (application specific integrated circuits) based on purchased IPs or self-developed modules in order to reduce power consumption and cost. For example, a user may also implement various communication modules, codecs, etc. using an FPGA (field programmable gate array), which may be used to verify the stability of a hardware design. Buffers are also commonly provided for various communication modules, codecs, etc., to temporarily store data generated during processing.

In some embodiments, where the WiFi-based wireless multimedia transport protocol is the DLNA protocol, the first system on a chip is further configured to: and forwarding the received audio/video data to the second wireless audio/video device via a WiFi communication mode or a bluetooth communication mode. Returning to fig. 1, the audio/video data received by the first system-on-chip is forwarded to the second system-on-chip for playback. Under the condition of router networking, the WiFi communication mode is utilized to forward the audio, and the router has the advantage of high transmission rate. The bluetooth communication mode may be that audio is forwarded between the first earpiece and the second earpiece over a bluetooth connection. Wherein the bluetooth communication mode has the effect of reducing the power consumption of the headset forwarding. Wherein, in some embodiments, when the second wireless audio/video device is singular, the first system-on-chip is further configured to: and forwarding the received audio/video data to the second wireless audio/video device via a bluetooth communication mode. For example, the first wireless audio/video device is a master sound box, the second wireless audio/video device is a slave sound box, when only one slave sound box exists, audio/video can be forwarded to a single slave sound box one to one through a Bluetooth mode, and the wireless audio/video device has the advantage of low power consumption. And on the basis, in some embodiments, the bluetooth communication mode comprises an improved bluetooth communication mode, the improved bluetooth communication mode improves a physical layer of bluetooth, the symbol rate of the physical layer reaches n Mb/s, n comprises an integer greater than or equal to 2, and the modulation mode comprises Quadrature Phase Shift Keying (QPSK), gaussian Frequency Shift Keying (GFSK) or QAM. The improved Bluetooth communication mode is characterized in that Bluetooth protocols are multiplexed at layers above a physical layer, such as a Bluetooth medium access control (mac) layer, a Bluetooth host control interface layer and the like, the physical layer can adopt symbol rate of n Mb/s, and the modulation mode can be Quadrature Phase Shift Keying (QPSK), gaussian Frequency Shift Keying (GFSK) or QAM. The improved Bluetooth communication mode has the function of reducing transmission power consumption compared with the WIFI communication mode; compared with the classical Bluetooth communication mode, the system has higher transmission capability and can transmit audio/video data with higher code rate.

Fig. 2 shows a second exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The smart device supports a customized DLNA protocol that allows the first soft access point to act as a repeater to forward audio/video data received from the smart device to a number of wireless audio/video devices. For example, as shown in fig. 2, there are 4 wireless audio/video devices in total, the first wireless audio/video device 110 creates the first soft access point 111, and the first soft access point 111 can not only receive audio data of the smart device 140, but also forward the received audio data to the second wireless audio/video device 210, the third wireless audio/video device 220, and the fourth wireless audio/video device 230. Therefore, by the customized DLNA protocol, one-to-many transmission of audio/video data can be achieved compared to the conventional DLNA protocol. For example, the master sound box is used as a first wireless audio/video device, a plurality of slave sound boxes can be provided, and the master sound box can forward audio to other slave sound boxes, so that audio sharing between the master sound box and the plurality of slave sound boxes can be realized.

Fig. 3 shows a third exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The smart device supports a conventional DLNA protocol, and the second system-on-chip is configured to: creating and activating a local second soft access point 122 in case the first wireless audio/video device 110 is to forward audio/video data received from the smart device 140; directly receiving audio/video data from the first wireless audio/video device 110 via the second soft access point 122 turned on according to the conventional DLNA protocol; the first system on a chip 111 is further configured to: creating a new DLNA connection 160 between the first soft access point 112 and the second soft access point 122; the audio data is forwarded to the second wireless audio device 120 via the first soft access point 112 over a new DLNA connection. The conventional DLNA protocol refers to a DLNA protocol supporting a one-to-one configuration of a sender to a receiver. In this case, the smart device and the first wireless audio/video device receive audio/video data of the smart device 140 through the first soft access point 112. The second wireless audio/video device 120 is caused to receive audio/video data forwarded by the first wireless audio/video device 110 via the newly created DLNA connection 160 between the first soft access point 112 and the second soft access point 122. This enables both the first wireless audio/video device 110 and the second wireless audio/video device 120 to be able to receive audio/video data even with the conventional DLNA protocol. The implementation of the existing DLNA protocol enabled smart device 140 pushing the sharing process of audio/video data to multiple wireless audio devices is facilitated.

In some embodiments, a first soft access point and a second soft access point are simultaneously set on a first system-on-chip, and the second system-on-chip is wirelessly connected with the second soft access point; or a fourth soft access point is arranged on the first system-on-chip, and the second system-on-chip is in wireless connection with the fourth soft access point. When the second soft access point and the first soft access point are simultaneously arranged on the first system-on-chip, the first soft access point receives the audio/video data from the intelligent device, directly transmits the audio/video data to the first system-on-chip for playing, transmits the audio/video data to the second soft access point, and then forwards the audio/video data to the second system-on-chip. If both the first soft access point and the second soft access point are located on the first system-on-chip, the transmission of audio/video data may be performed by means of a wired connection. The fourth soft access point can realize the functions of the first soft access point and the second soft access point simultaneously, and the fourth soft access point can not only receive the audio/video data from the intelligent device, but also forward the audio/video data to the second system on a chip.

In some embodiments, the first system-on-chip is further configured to: after the local first soft access point is started, audio data from the intelligent equipment is directly received through the started first soft access point according to an AirPlay protocol and is forwarded to the second wireless audio/video device. The AirPlay protocol supports a one-to-many configuration of the sender and receiver, and the first soft access point may act directly as a repeater to forward received audio data to the second wireless audio/video device for playback. Compared with the conventional DLNA protocol, the method has the advantage of more convenient communication push of audio/video data.

In some embodiments, the first system on a chip is further configured to communicate continuously with the smart device in BLE communication mode to learn whether the smart device is not connected to the router; and under the condition that the intelligent device is not connected with the router, starting a local soft access point created according to the configuration information of the router, directly receiving audio/video data from the intelligent device through the started soft access point according to the WiFi-based wireless multimedia transmission protocol, and forwarding the received audio/video data. Returning to the embodiment shown in fig. 1, the first system-on-chip creates a first soft access point when the router is not connected. The first system-on-chip is not aware when the smart device is unable to connect to the router and therefore does not turn on the first soft access point, which may result in a disconnection of the wireless connection between the first system-on-chip and the smart device. Continuous communication is carried out with the first system on a chip through the intelligent device in a BLE communication mode, the first system on a chip can be timely informed of the condition of a connection router of the intelligent device, the first system on a chip is convenient to timely establish a soft access point, then the first system on a chip can continuously receive audio/video data sent by the intelligent device, and the problem that communication cannot be carried out based on a wireless multimedia transmission protocol of WiFi due to disconnection of the intelligent device and the router is avoided.

Fig. 4 shows a fourth exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The first system on a chip 110 is further configured to: acquiring a first power of the first wireless audio/video device 110 and a second power of the second wireless audio/video device 120 during the process of directly receiving audio/video data from the smart device 140 via the turned-on first soft access point 111 according to the WiFi-based wireless multimedia transmission protocol; and determining whether the first power level is less than the second power level by at least a predetermined degree, and if so, notifying the second system-on-chip 121 to create and turn on a third soft access point 123 based on the configuration information of the router, the second system-on-chip 121 being further configured to: creating and turning on a third soft access point 123 based on the configuration information of the router in response to the notification; audio/video data from the smart device 140 is received directly via the third soft access point 123, which is turned on, according to the WiFi-based wireless multimedia transmission protocol, and the received audio/video data is forwarded to the first system on chip 111. Since the first system-on-chip 111 creates the first soft access point 112 to receive the audio/video data, and the first system-on-chip 111 needs to forward the audio/video data to the second system-on-chip 121, and the power consumption of the wireless device when transmitting the radio frequency signal is much greater than that of the receiving, the power consumption of the first system-on-chip 111 for turning on the first soft access point 112 is higher than that of the second system-on-chip 121, and the residual power of the first system-on-chip 111 is easily smaller than that of the second system-on-chip 121. The first system-on-chip 111 may obtain the second power of the second system-on-chip 121 through bluetooth communication, wiFi communication, or the like and inform the second system-on-chip 121 to create the third soft access point 123. In the determining process, the first power level and the second power level may be compared, when the first power level is determined to be less than the second power level by at least a predetermined degree, for example, the predetermined degree may be a preset value, and when the value of the first power level less than the second power level reaches or exceeds the preset value, the second system on chip 121 is notified to turn on the third soft access point 123. In some cases, the above-described predetermined value may be set smaller as the first electric quantity is smaller. Thus, the smaller the first power, the more stringent the power requirement is to be reduced, and the easier it is to switch soft access points. The second system on chip 121 is thus switched to directly receive the audio/video data of the intelligent device 140 and send the audio/video data to reduce the power consumption of the first wireless audio/video device 110, so as to prolong the service time of the first wireless audio/video device 110. It can be seen that the soft access point switching based on the first power being smaller than the second power can extend the usage time of the first wireless audio/video device 110. And, after the third soft access point 112 starts to receive the audio/video data of the smart device 140, it starts to forward the received audio/video data to the first system on chip 111, so as to avoid interruption or jamming of the audio/video played by the first system on chip 111.

The intelligent device is connected with the first soft access point or the third soft access point, and the intelligent device can only be connected with one soft access point at the same time. In the switching process, the intelligent equipment does not change the mode of pushing the audio/video data, and only perceives the interaction of information with the soft access point, and does not perceive difference for different soft access points, so that the settings of the first wireless audio/video device and the second wireless audio/video device in terms of software and hardware can be the same in the switching process, and the updating or correction in terms of software and hardware is not needed.

Fig. 5 shows a fifth exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The first system on a chip 111 is further configured to: in the case where the second system-on-chip 121 creates and turns on the third soft access point 123 and receives audio/video data from the smart device 140 via the turned-on third soft access point 123, the reception of audio/video data from the smart device 140 via the first soft access point 112 is stopped, but the first soft access point 112 is kept continuously turned on, so that the forwarding of the audio/video data that has been received to the second system-on-chip 121 can be continued until the forwarding is completed and the first soft access point 112 is turned off again; the second system-on-chip 121 is further configured to: with the first soft access point 112 off, the received audio/video data is forwarded to the first system on chip 111 via the third soft access point 123 on in accordance with the WiFi-based wireless multimedia transfer protocol. The first wireless audio/video device 110 and the second wireless audio/video device 120 perform switching as primary and secondary sides, and the first soft access point 112 is not used to receive the audio/video data of the intelligent device 140 under the condition that the third soft access point 123 of the second wireless audio/video device 120 is switched to receive the audio/video data of the intelligent device 140. But still turn on the first soft access point 112 for forwarding until the audio/video received from the smart device 140 is forwarded, the first soft access point 112 is turned off. Therefore, the wireless transmission performance can be influenced as little as possible, and the audio played on the second earphone is prevented from being interrupted or blocked. And, in the case that the first soft access point 112 is turned off, the third soft access point 123 starts to forward the received audio/video to the first system on chip 111, so that interruption or jamming of the audio/video played by the first system on chip 111 can be avoided.

Fig. 6 shows a sixth exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The first system on a chip 111 is further configured to: playing the audio/video data in case of receiving the audio/video data from the smart device 140, and storing the audio/video data in the buffer 113; with the first soft access point 112 turned on, the audio/video data in the buffer 112 is forwarded to the second system on chip 121. Taking the example of an ear-facing earphone, the first soft access point of the first earphone (the first wireless audio/video device 110) receives audio data of the smart device, on the one hand, the audio data or a part of the audio data (such as one of the left and right channels of audio data) is given to the first earphone for playing, and on the other hand, the received audio data or a part of the audio data is put in the buffer, so that the first earphone necessarily has a part of the audio data to be relayed to the second earphone (the second wireless audio/video device 120), and then the audio data in the buffer is sent to the second earphone by the first soft access point.

Fig. 7 shows a seventh exemplary communication structure diagram of a wireless audio/video device according to an embodiment of the present application. The first system on a chip 111 is further configured to: in the case that the second system-on-chip 121 creates and opens the third soft access point 123 and receives audio/video data from the smart device 140 via the opened third soft access point 123, closing the first soft access point, and continuing to forward the received audio/video data to the second system-on-chip 121 via the bluetooth communication mode 170 or the modified bluetooth communication mode, so as to prevent interruption or jamming of audio played on the second wireless audio/video device 120; the second system-on-chip 121 is further configured to: in case the received audio/video data is forwarded over, the received audio/video data is forwarded to the first system on chip 111 via the bluetooth communication mode 170 or a modified bluetooth communication mode. The second system on chip 121 is not responsible for forwarding audio/video data through the third soft access point 123. The audio/video data buffered by the first system on chip 111 is transmitted to the second system on chip 121 via the bluetooth communication mode 170 or a modified bluetooth communication mode. The second system on chip 121 forwards the new audio/video data also via the bluetooth communication mode 170 or a modified bluetooth communication mode. This can greatly reduce the transmission power consumption of the first wireless audio/video device 110 and the second wireless audio/video device 120. The power consumption of the first wireless audio/video device 110 and the second wireless audio/video device 120 is reduced, and the service time of the first wireless audio/video device 110 and the second wireless audio/video device 120 is prolonged.

In some embodiments, the first system-on-chip is further configured to: playing the audio/video data and storing the audio/video data in a buffer under the condition of receiving the audio/video data from the intelligent device; the audio/video data in the buffer is forwarded to the second system-on-chip via a bluetooth communication mode or a modified bluetooth communication mode. Returning to fig. 6, the buffered data in the buffer of fig. 6 is forwarded to the second system-on-chip through the first soft access point. Unlike fig. 6, the audio/video data in the buffer may also forward the buffered data to the second system-on-chip through the bluetooth communication mode or the modified bluetooth communication mode, thereby reducing the transmission power consumption of the first system-on-chip, which is beneficial to reducing the power consumption of the first wireless audio/video device and prolonging the service time of the first wireless audio/video device.

In some embodiments, the first system-on-chip is further configured to: the configuration information of the router is stored in advance, or the configuration information of the router is obtained from the intelligent equipment; and/or the second system-on-chip is further configured to: the configuration information of the router is stored in advance, or the configuration information of the router is obtained from the intelligent device, or the configuration information of the router is obtained from the first system-on-chip. The first system-on-chip may be transmitted to the second system-on-chip by means of bluetooth communication, wiFi communication, etc. If the second system-on-chip stores the configuration information of the router or stores the configuration information of the router in advance in the process of receiving the first soft access point as a repeater for forwarding the audio/video data, the first system-on-chip does not need to be sent to the second system-on-chip. In some embodiments, the second system-on-chip creates a third soft access point based on a different configuration information of the router than the router of the first soft access point; the second soft access point is based on the different configuration information of the router from the first soft access point; the second soft access point and the third soft access point are based on the same or different configuration information of the router. Because the second soft access point and the first soft access point have a state of being simultaneously on, such as the first soft access point is likely to be responsible for forwarding buffered data even if it does not receive audio/video data from the smart device, the third soft access point and the second soft access point have a state of being simultaneously on. Creating the first soft access point may be the configuration information of a router to which the first wireless audio/video device is commonly connected with the smart device. Creating the third soft access point may be the configuration information of a router to which the second wireless audio/video device is commonly connected with the smart device. The configuration information for creating the second soft access point may be configuration information of a router to which the first wireless audio/video device and the second wireless audio/video device are commonly connected.

In one embodiment, the first system-on-chip is configured to: continuously communicating with the smart device via a BLE communication mode to learn whether the smart device is to transmit audio data; the first soft access point created locally is turned on knowing that the smart device is to send audio data and that the router is not attached. The first system-on-chip communicates continuously with the intelligent device in a BLE communication mode, and when the intelligent device is to send audio/video data to the first system-on-chip, the intelligent device notifies the first system-on-chip through the BLE communication mode. Thus, when the intelligent device does not need to send audio data to the earphone, the soft access point of the earphone can be disabled, and the BLE communication module of the earphone is still in operation. This greatly reduces the power consumption of the headset when it is on standby or when it is not needed to transmit audio data.

In one embodiment, the first system-on-chip is configured to: and judging whether the first earphone is taken out from the charging box or in the ear, and if so, starting a first soft access point which is created locally under the condition that the router becomes disconnected. When the first earpiece is removed from the charging cartridge, indicating that the first earpiece is not charged, the user may need to use the first earpiece to play audio, if at this time the first earpiece is also not connected to the router, creating a first soft access point. This may improve the user experience. When the first earphone is detected in the ear, the user may use the first earphone to play audio, if the first earphone is not connected with the router at the moment, the first soft access point is created, and if the first earphone is not in the ear, the first soft access point is closed. Therefore, the use experience of a user can be improved, and the power consumption of the earphone when the earphone is not in the ear can be reduced. In-ear detection may be achieved by mounting a capacitive sensor, an optical sensor, etc. on the headset.

A wireless communication method according to an embodiment of the present application is specifically described below.

Fig. 8 shows a flow diagram of a wireless communication method according to an embodiment of the present application. The wireless communication method is used for supporting communication between the wireless audio/video device and the intelligent equipment based on the WiFi wireless multimedia transmission protocol. The wireless multimedia transmission protocol based on WiFi includes any one of DLNA protocol, airPlay protocol and Miracast protocol and the improved protocol based thereon. First, in step 801, a wireless audio/video apparatus is provided that includes a first wireless audio/video device and a second wireless audio/video device that are grouped and cooperate. The first wireless audio/video device and the second wireless audio/video device may include a pair of ear phones with a first earpiece and a second earpiece, a master slave speaker, etc.

Next, at step 802, an attempt is made by the first wireless audio/video device to connect to a router based on configuration information of the router that is required to build a wireless local area network on which the WiFi-based wireless multimedia transmission protocol depends. In some embodiments, the configuration information of the router includes a network name and password of the router. Before the first wireless audio/video device wants to receive audio/video data based on the wireless multimedia transmission protocol of WiFi, the first wireless audio/video device attempts to connect to the router, and then judges whether the router is available or not so as to establish a first soft access point or not in the next step. Next, steps 803 and 804 are performed.

Step 803, receiving, by the first wireless audio/video device, audio/video data from the smart device or cloud server via the router in accordance with the WiFi-based wireless multimedia transmission protocol, with the router connected. In the case of router networking, the router is responsible for forwarding audio/video data of the smart device or cloud server to the first wireless audio/video device, which receives the audio/video data. In addition, the audio/video data may be sent directly to the second wireless audio/video device via a router, such as may be forwarded to the second wireless audio/video device via a wireless connection or bluetooth connection between the first wireless audio/video device and the second wireless audio/video device.

Step 804, when the router is not connected, the first wireless audio/video device starts a local first soft access point created according to the configuration information of the router, and directly receives audio/video data from the intelligent device according to the WiFi-based wireless multimedia transmission protocol via the started first soft access point. The first wireless audio/video device may not be connected to the router because the first wireless audio/video device is not within the connection range of the router or the router is not operational, at which time a local first soft access point is created by the configuration information of the connected router. In the process that the first wireless audio/video device is connected with the router, the intelligent device stores the configuration information of the router, so that the intelligent device can be directly connected with the first soft access point in a wireless mode under the condition that the first wireless audio/video device is not connected with the router, a user does not need to manually input the configuration information of the router, and the operation of the user can be facilitated. In the case of a wireless network established by a first soft access point, the intelligent device transmits audio/video data to the first soft access point, which transmits the audio/video data to the first wireless audio/video device. The first wireless audio/video device can receive audio/video data for playing, so that the first soft access point can support the use of a wireless multimedia transmission protocol based on WiFi under the condition that the first wireless audio/video device cannot be connected with the router. The limitation that the router can only be used under the networking of the router is overcome, and the router is convenient for users to use.

The received audio/video data is then forwarded by the first wireless audio/video device to the second wireless audio/video device in step 805. In step 804, the first wireless audio/video device is used as a receiving party for transmitting the intelligent device, and the second wireless audio/video device cannot directly receive the audio/video data, so that the first wireless audio/video device forwards the audio/video data to be received to the second wireless audio/video device for playing by the second wireless audio/video device.

It should be noted that the steps 803 to 805 are not necessarily performed in the order of fig. 8, but may be performed alternately, and the execution order of the steps 803, 804, and 805 may be exchanged without affecting the logic of each other. Specifically, after the first wireless audio/video device attempts to connect to the router in step 802, it is divided into two cases, and in the case of connecting to the router, step 803 is correspondingly performed. Steps 804 and 805 are performed without connection to the router to create the first soft access point, and still transmit audio/video data based on the WiFi wireless multimedia transmission protocol.

In some embodiments, in the case where the WiFi-based wireless multimedia transmission protocol is a DLNA protocol, the received audio/video data is forwarded by the first wireless audio/video device to the second wireless audio/video device via a WiFi communication mode or a bluetooth communication mode. Returning to step 805 shown in fig. 8, the first wireless audio/video device forwards the audio or video data through a WiFi communication mode or a bluetooth communication mode. For example, audio or video data is transmitted between the first earpiece and the second earpiece via a wireless connection or a bluetooth connection. With a bluetooth connection having lower transmit power consumption than with a wireless connection. Wherein in some embodiments, when the second wireless audio/video device is singular, the received audio/video data is forwarded by the first wireless audio/video device to the second wireless audio/video device via a bluetooth communication mode. Because the conventional DLNA protocol supports one-to-one configuration, for example, the first wireless audio/video device is a master sound box, and the second wireless audio/video device is a slave sound box, when only one slave sound box exists, audio/video can be forwarded to a single slave sound box one-to-one through a Bluetooth mode, and the Bluetooth type wireless audio/video device has the advantage of low power consumption. And on the basis, in some embodiments, the bluetooth communication mode comprises an improved bluetooth communication mode, the improved bluetooth communication mode improves a physical layer of bluetooth, the symbol rate of the physical layer reaches n Mb/s, n comprises an integer greater than or equal to 2, and the modulation mode comprises Quadrature Phase Shift Keying (QPSK), gaussian Frequency Shift Keying (GFSK) or QAM. The improved Bluetooth communication mode is characterized in that Bluetooth protocols are multiplexed at layers above a physical layer, such as a Bluetooth medium access control (mac) layer, a Bluetooth host control interface layer and the like, a symbol rate of 2Mb/s can be adopted at the physical layer, and a modulation mode can be Quadrature Phase Shift Keying (QPSK), gaussian Frequency Shift Keying (GFSK) or QAM. The improved bluetooth communication mode has the effect of reducing transmission power consumption.

In some embodiments, the wireless communication method further comprises: customizing DLNA protocol to allow the first soft access point to act as a repeater to forward audio/video data received from the smart device to a plurality of wireless audio/video devices; a custom DLNA protocol is used as the WiFi-based wireless multimedia transmission protocol. Compared with the conventional DLNA protocol, the customized DLNA protocol can realize one-to-many transmission of audio/video data by using the first soft access point as a repeater. For example, the master sound box is used as a first wireless audio/video device, a plurality of slave sound boxes can be provided, and the master sound box can forward audio to other slave sound boxes, so that audio sharing between the master sound box and the plurality of slave sound boxes can be realized.

In some embodiments, the wireless communication method further comprises: conventional DLNA protocol is used as WiFi-based wireless multimedia transmission protocol; creating and activating a local second soft access point by the second wireless audio/video device in case the first wireless audio/video device is to forward audio/video data received from the smart device; creating a new DLNA connection using the first soft access point and the second soft access point; forwarding, by the first wireless audio/video device, the audio/video data to the second wireless audio device over a new DLNA connection. The conventional DLNA protocol refers to a DLNA protocol supporting a one-to-one configuration of a sender to a receiver. In this case, the smart device and the first wireless audio/video device receive audio/video data of the smart device through the first soft access point. And enabling the second wireless audio/video device to receive the audio/video data forwarded by the first wireless audio/video device through the newly created DLNA connection between the first soft access point and the second soft access point. Thus, even through the conventional DLNA protocol, it is possible to realize that both the first wireless audio/video device and the second wireless audio/video device can receive audio/video data.

In some embodiments, the wireless communication method further comprises: using an AirPlay protocol as the WiFi-based wireless multimedia transmission protocol; after a local first soft access point is started, the first wireless audio/video device directly receives audio data from the intelligent equipment through the started first soft access point according to an AirPlay protocol; forwarding, by the first wireless audio/video device, the audio data to the second wireless audio/video device via the turned-on first soft access point. The AirPlay protocol can relay and send audio/video data to a plurality of receivers, and has the advantage of more convenient communication pushing of the audio/video data compared with the conventional DLNA protocol. And thus may be sent directly to the second wireless audio/video device via the first soft access point that is turned on. Of course, in order to save power consumption, the first wireless audio/video device may also forward the received audio/video data to the second wireless audio/video device via the bluetooth communication mode.

In some embodiments, the wireless communication method further comprises: and carrying out continuous communication in a BLE communication mode with the intelligent device by the first wireless audio/video device so as to know whether the intelligent device is not connected with the router. Returning to the process shown in fig. 8, a first soft access point is created without the first wireless audio/video device connected to the router. But in case the smart device cannot connect to the upper router, it is just as impossible to transmit audio/video data using the WiFi-based wireless multimedia transmission protocol. Therefore, the intelligent device continuously communicates with the first wireless audio/video device in a BLE communication mode, the condition of a connection router of the intelligent device can be timely known, the first wireless audio/video device is convenient to establish a soft access point, then the first wireless audio/video device can continuously receive audio/video data sent by the intelligent device, and the problem that communication cannot be carried out based on a wireless multimedia transmission protocol of WiFi due to the fact that the intelligent device is disconnected with the router is avoided.

Fig. 9 shows a flow diagram of a wireless communication method according to another embodiment of the present application. Firstly, in step 901, in a process that a first wireless audio/video device directly receives audio/video data from the smart device via an opened first soft access point according to the WiFi-based wireless multimedia transmission protocol, a first electric quantity of the first wireless audio/video device and a second electric quantity of a second wireless audio/video device are obtained. Because the first wireless audio/video device creates the first soft access point to receive the audio/video data, and the first wireless audio/video device also needs to forward the audio/video data to the second wireless audio/video device, the power consumption of the wireless device when transmitting the radio frequency signal is far greater than that of the wireless device, so that the power consumption of the first wireless audio/video device is higher than that of the second wireless audio/video device, and the residual electric quantity is easier to be smaller than that of the second wireless audio/video device. It is therefore necessary to acquire a first power of the first wireless audio/video device and a second power of the second wireless audio/video device in step 901, respectively.

Next, at decision step 902, a determination is made as to whether the first charge is less than the second charge by at least a predetermined amount. If the result of the decision step 902 is yes, i.e. if the difference between the first power level and the second power level has reached a value or a predetermined value, it is indicated that the first wireless audio/video device may not be suitable as a forwarding device in the following. In some cases, the above-described predetermined value may be set smaller as the first electric quantity is smaller.

Next, step 903 is performed, where a third soft access point is created and turned on by the second wireless audio/video device based on the configuration information of the router. Because the electric quantity of the first wireless audio/video device is smaller, and the electric quantity of the second wireless audio/video device is relatively larger, then the third soft access point of the second wireless audio/video device is started, and then the third soft access point is used as forwarding equipment.

Next, step 904 is performed, by the second wireless audio/video device, directly receiving audio/video data from the smart device via the third soft access point turned on according to the WiFi-based wireless multimedia transmission protocol. The third soft access point uses configuration information of the router to which the intelligent device is connected. Thus, after the third soft access point is created, the intelligent device can be directly connected with the third soft access point to realize seamless switching, and from the perspective of the intelligent device, audio/video data is always sent to the wireless audio/video device, and the first wireless audio/video device or the second wireless audio/video device is not distinguished. The settings of the first wireless audio/video device and the second wireless audio/video device in terms of software and hardware can be the same during the switching process, and no upgrades or modifications in terms of software and hardware are required.

Step 905 then proceeds to forward the received audio/video data by the second wireless audio/video device to the first wireless audio/video device. Therefore, the first wireless audio/video device is not responsible for forwarding data, but only receives data, so that the power consumption is reduced, the power consumption is convenient to reduce, the service time is prolonged, and the use experience of a user is improved. It can be seen that the soft access point switching based on the first power being smaller than the second power can extend the usage time of the first wireless audio/video device 110.

As shown in fig. 5, in some embodiments, the wireless communication method further comprises: in the case that the second wireless audio/video device creates and opens a third soft access point and receives audio/video data from the intelligent device via the opened third soft access point, stopping the first wireless audio/video device from receiving the audio/video data from the intelligent device via the first soft access point, but keeping the first soft access point continuously opened so that the received audio/video data can be continuously forwarded to the second wireless audio/video device until the forwarding is completed and then closing the first soft access point; forwarding, by the second wireless audio/video device, the received audio/video data to the first wireless audio/video device via the turned-on third soft access point in accordance with the WiFi-based wireless multimedia transmission protocol, with the first soft access point turned off. Taking the primary second earphone as an example, the first soft access point is no longer utilized to receive the audio/video data of the intelligent device. But still turning on the first soft access point to forward until the audio/video received from the smart device is forwarded, and turning off the first soft access point. Therefore, the wireless transmission performance can be influenced as little as possible, and the audio played on the main second earphone is prevented from being interrupted or blocked. And under the condition that the first soft access point is closed, the third soft access point starts to forward the received audio/video to the first system-on-chip, so that interruption or blocking of the audio/video played by the first system-on-chip can be avoided.

As shown in fig. 7, in some embodiments, the wireless communication method further comprises: closing the first soft access point under the condition that the second wireless audio/video device creates and opens a third soft access point and receives audio/video data from the intelligent device through the opened third soft access point; continuing, by the first wireless audio/video device, forwarding of the audio/video data that has been received to the second wireless audio/video device via a bluetooth communication mode or a modified bluetooth communication mode; and forwarding, by the second wireless audio/video device, the received audio/video data to the first wireless audio/video device via the bluetooth communication mode or a modified bluetooth communication mode, in the event that the forwarding of the received audio/video data is completed. Unlike fig. 5, the first soft access point is not utilized for forwarding audio/video data, and is turned off, and the bluetooth communication mode or modified bluetooth communication mode is utilized for forwarding audio/video data buffered in the first wireless audio/video device. Moreover, the second wireless audio/video device also forwards newly received audio/video data via a bluetooth communication mode or a modified bluetooth communication mode. This can reduce the power consumption of the first wireless audio/video device and the second wireless audio/video device for forwarding.

In some embodiments, the wireless communication method further comprises: playing, by the first wireless audio/video device, audio/video data from the smart device upon receiving the audio/video data, and storing the audio/video data in a buffer; forwarding, by the first wireless audio/video device, audio/video data in a buffer to the second wireless audio/video device via a bluetooth communication mode or a modified bluetooth communication mode. Taking an example of an ear phone, the first soft access point of the first earphone receives audio data of the intelligent device, on one hand, the audio data or part of the audio data (such as one channel data of left and right channels) is sent to the first earphone for playing, on the other hand, the received audio data or part of the audio data is placed in a buffer, and the audio/video data in the buffer can be forwarded to the second earphone through a Bluetooth communication mode or an improved Bluetooth communication mode, so that the transmitting power consumption of the first earphone is reduced.
