Detailed Description
The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The master-slave mode switching method provided by the embodiment of the invention can be applied to the application environment shown in fig. 1. Specifically, the master-slave mode switching method is applied to a multimedia synchronous playing system, where the multimedia synchronous playing system may include a master device and at least one slave device, that is, the multimedia synchronous playing system may include a device in a master mode and at least one device in a slave mode, where a user may send a control instruction, including instructions of playing, pausing, and the like, to the devices in the slave mode in a multimedia playing group through the devices in the master mode, so as to implement multimedia synchronous playing. In this embodiment, it is described that the multimedia synchronous playing system includes a first device 10 and a second device 11 as shown in fig. 1 as an example, where the first device 10 and the second device 11 establish a communication connection through a wireless network, belong to the same multimedia playing group, and are used to implement that the first device 10 and the second device 11 can synchronously play multimedia files. Taking the example that the first device 10 is currently in the slave mode and the second device 11 is currently in the master mode, when determining that the first device 10 needs to be switched from the slave mode to the master mode, the first device 10 sends a switching notification to the second device 11 in the multimedia play group, where the switching notification includes information of a wireless local area network to be created by the first device 10, and then the first device 10 creates a corresponding wireless local area network, so that the second device 11 in the multimedia play group accesses the wireless local area network according to the switching notification and switches to the master mode; at this time, the second device 11 switches from the master mode to the slave mode after accessing the wireless local area network created by the first device 10 according to the switching notification sent by the first device 10. The device is rapidly switched between the master control mode and the slave mode, the switching operation is convenient, and the user experience is effectively improved. The first device 10 and the second device 11 may include, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, smart stereos, and portable wearable devices with a playing function.
Referring to fig. 2, a master-slave mode switching method provided in an embodiment of the present invention is described by taking the example that the master-slave mode switching method is applied to the first device 10 in fig. 1, and includes the following steps:
step S101: when determining that a slave mode needs to be switched to a master mode, a first device sends a switching notification, wherein the switching notification comprises wireless local area network information to be created by the first device;
here, an application APP for controlling the multimedia synchronous playing system may be installed in the first device, and a user may manage a device in a master mode and a device in a slave mode in the multimedia synchronous playing system through the application APP, including a switching mode and the like. The device in the master mode can transmit multimedia data and issue a control instruction to the device in the slave mode, so that the device in the slave mode performs corresponding processing according to the received multimedia data and the control instruction. When a user switches a mode on a user interface of the APP and the first device is currently in the slave mode, which is equivalent to that the first device determines that the slave mode needs to be switched to the master mode, indicating that the user wants to play and manage other devices in the multimedia play group through the first device at the time, the first device sends a switching notification to the other devices in the multimedia play group, where the switching notification includes information of a wireless local area network to be created by the first device, so as to notify that the other devices in the multimedia play group can join the wireless local area network created by the first device, thereby realizing that the first device is switched from the slave mode to the master mode. In one embodiment, the determining, by the first device, that a switch from a slave mode to a master mode is required includes: when the first device is in the slave mode, the first device detects whether an operation instruction for switching to the master control mode is received; if so, the first device determines that the slave mode needs to be switched to the master mode. It can be understood that a user interface for mode switching may be provided in the first device, and a user may switch the operating mode in the user interface, and if the first device is currently in the slave mode, and at this time, the user clicks a mode switching key or clicks a master mode key, the first device receives an operation instruction for switching to the master mode.
It should be noted that the first device may send the switching notification to other devices in the multimedia play group in different manners. In an embodiment, the sending, by the first device, a handover notification to other devices in the multimedia play group includes: and the first equipment broadcasts a switching notice to other equipment in the multimedia playing group through Bluetooth. It can be understood that, when the bluetooth function is turned on, the first device may broadcast the switching notification to the surrounding through its own bluetooth broadcast channel, and since the distances between the other devices in the multimedia play group and the first device are usually short, it may be considered that the first device broadcasts the switching notification to the other devices in the multimedia play group through bluetooth. Therefore, the first equipment switches the notification through Bluetooth broadcasting, the power consumption is low, and the speed is high. In an embodiment, the sending, by the first device, a handover notification to other devices in the multimedia play group includes: and the first equipment broadcasts a switching notification to other equipment in the multimedia playing group based on a wireless local area network provided by second equipment in a master control mode in the multimedia playing group. It can be understood that, in the multimedia synchronous playing system, the first device in the slave mode needs to join the wireless local area network provided by the second device in the master mode first to establish a communication connection therebetween, so as to form a private network environment, thereby realizing synchronous playing of multimedia with the second device. The first device may broadcast a handover notification to other devices in the multimedia play set based on a wireless local area network provided by the second device based on a communication connection with the second device. It should be noted that, if the first device cannot directly broadcast the switching notification to all other devices in the multimedia play group based on the wireless local area network provided by the second device in the master control mode in the multimedia play group, the broadcasting, by the first device, the switching notification to other devices in the multimedia play group based on the wireless local area network provided by the second device in the master control mode in the multimedia play group by the first device may include: and the first equipment sends a request message carrying a switching notification to second equipment based on a wireless local area network provided by the second equipment in a master control mode in the multimedia playing group, so that the second equipment broadcasts the switching notification to equipment which is in a slave mode in the multimedia playing group and is except the first equipment. It can be understood that, the first device sends a request message carrying a handover notification to the second device based on a wireless local area network provided by the second device in the master control mode in the multimedia play group, that is, based on a communication connection established between the first device and the second device, so that the second device sends the handover notification to other devices in a slave mode and in a communication connection with the second device according to the request message, and the other devices know the handover notification. Therefore, the first equipment broadcasts the switching notice to the equipment which is in the slave mode in the multimedia playing group and is except the first equipment through the second equipment, the equipment in the multimedia playing group can be ensured to be completely informed of the switching notice, and the switching accuracy is improved.
Step S102: and the first equipment creates a corresponding wireless local area network so that other equipment in the multimedia playing group can access the wireless local area network according to the switching notification and further switch to a master control mode.
Specifically, the first device creates a corresponding wireless local area network according to the wireless local area network information to be created, so that other devices in the multimedia playing group access the wireless local area network according to the wireless local area network information in the switching notification, and switching from a slave mode to a master mode is achieved.
Here, the wireless lan information may be different depending on the setting of the wireless lan. For example, when the access password of the network does not need to be set, the wireless local area network information may include only the network name; when the access password of the network needs to be set, the wireless local area network information may include a network name and an access password. In practical applications, the network name may be identification information of the first device, such as a model number. In one embodiment, the first device creates a corresponding wireless local area network, including: and the first equipment opens a hotspot and sets the network name and the access password of the hotspot according to the wireless local area network information so as to create a wireless local area network taking the first equipment as the wireless hotspot. Therefore, the first device can establish communication connection with the first device through the hot spot by starting the hot spot, and further realize that the first device is switched from the slave mode to the master mode. Meanwhile, the data transmission through the hot spot has the advantage of high speed. The first device may create a corresponding wireless local area network, or the first device may create a corresponding wireless local area network through a short-range wireless communication method such as bluetooth.
In summary, in the master-slave mode switching method provided in the above embodiment, when the first device in the slave mode needs to be switched to the master mode, the first device sends the switching notification of the to-be-created wlan information, so that other devices in the multimedia play set access the created wlan according to the switching notification, thereby switching to the master mode, implementing fast switching of the devices between the master mode and the slave mode, and being convenient and fast to operate, thereby effectively improving user experience.
Based on the same inventive concept of the foregoing embodiment, referring to fig. 3, another master-slave mode switching method provided in the embodiment of the present invention is described by taking the example that the master-slave mode switching method is applied to the second device 11 in fig. 1, and includes the following steps:
step S201: the second equipment receives a switching notice, wherein the switching notice comprises the information of the wireless local area network to be established by the first equipment;
specifically, the second device receives a switching notification broadcasted by bluetooth from the first device in the same multimedia playing group, or the second device receives a switching notification broadcasted by wireless local area network from the first device in the same multimedia playing group through the second device in the master control mode.
It should be noted that, before receiving the switching notification sent by the first device in the same multimedia play group, the second device may be in the slave mode or the master mode. When the second device is in the master control mode, the second device receives a handover notification sent by a first device in the same multimedia play group, where the handover notification may be a request message carrying the handover notification sent by the first device, and correspondingly, when the second device receives the handover notification sent by the first device, the method may further include: and the second equipment broadcasts the switching notification to other equipment in the multimedia playing group through a wireless local area network established by the second equipment. It can be understood that, when the first device cannot directly send the switching notification to other devices in the multimedia play group, the second device in the master mode may be indirectly requested to send the switching notification to other devices in the multimedia play group except the second device, and the second device broadcasts the switching notification to the devices in the slave mode in the multimedia play group except the first device, so that the switching notification can be known by all devices in the multimedia play group.
Step S202: and the second equipment accesses the wireless local area network created by the first equipment according to the wireless local area network information.
Specifically, after searching for the wireless local area network created by the first device according to the wireless local area network information, the second device sends a connection request to the first device based on the wireless local area network information to access the wireless local area network created by the first device, so as to join in a multimedia play group managed by the first device.
It should be noted that, when the second device is in the master control mode before or during receiving the switching notification sent by the first device, after the second device receives the switching notification sent by the first device, the method further includes: the second device switches from a master mode to a slave mode. At this time, if the multimedia play set continues to play the multimedia data, the second device may first control the multimedia play set to pause playing the multimedia data.
In summary, in the master-slave mode switching method provided in the above embodiment, after receiving a switching notification of wlan information to be created by a first device sent by the first device, a second device accesses the wlan created by the first device according to the switching notification, so that the first device switches from the slave mode to the master mode, thereby implementing fast switching of the device between the master mode and the slave mode, and being convenient and fast to operate, and effectively improving user experience.
Based on the same inventive concept of the foregoing embodiment, this embodiment describes in detail the technical solution of the foregoing embodiment by using a specific example, in this embodiment, taking a device in the master mode as a master and a device in the slave mode as a slave, referring to fig. 4, an interaction process of the master-slave mode switching method is as follows:
1) the host computer creates a hot spot;
here, the host may open a hotspot, generate a two-dimensional code according to the hotspot information, and display the two-dimensional code, so that the slave 1, the slave 2, the slave 3, and the like establish communication connection with the host by scanning the two-dimensional code, and the slave 1, the slave 2, and the like join the current hotspot after scanning the code to form a local area network. Here, the hotspot information may include a hotspot name, a password, and the like, so that a slave can directly connect to the hotspot by scanning the two-dimensional code.
2) The slave 1 applies for identity change;
here, when the slave 1 needs to be changed to a new master, it needs to apply for an identity change.
3) The slave 1 informs the host and the slave 2 of the hotspot information to be generated through Bluetooth broadcasting or a currently established WiFi local area network;
here, the slave 1, whether in a bluetooth broadcast mode or in an established WiFi local area network, is to transmit hotspot information prepared to be generated by itself to the master and other slaves.
4) The slave 1 creates hotspot information;
5) the host and the slave 2 are automatically connected with the hot spot created by the slave 1;
6) the slave 1 switching identity is completed.
Here, after the master automatically connects to the hotspot created by the slave 1, the identity of the master will become the slave, and the identity of the slave 1 becomes the new master.
Therefore, the identities of the host and the slave are dynamically adjusted based on WiFi hotspots or Bluetooth broadcasting and the like, and the operation is convenient and fast. The user experience is promoted.
