In addition, the technical features mentioned in the different embodiments of the present application described below may be combined with each other as long as they do not conflict with each other.
The stereo playing setting method for the broadcast networking can be applied to the Bluetooth networking with a plurality of playing devices, the playing devices in the networking are grouped according to the requirements of users, and audio playing is carried out in a pairwise grouping mode and/or a 1-N mode.
The stereo playing setting method for the broadcast networking is not only suitable for wireless communication based on a Bluetooth wireless communication protocol, but also suitable for other wireless communication fields such as WIFI.
Referring to fig. 1, a flowchart illustration of a stereo play setting method for broadcast networking according to an embodiment of the present application is shown, including:
Specifically, a user selects a playing device in the broadcast networking, the selected device is a first playing device, and the selected playing device enters a stereo playing mode according to a first operation performed by the user, for example: after a user presses a 'Play' key on the playing equipment for a long time, the playing equipment enters a stereo playing mode; if the user clicks the 'start up' key and the historical team formation record is recorded on the first playing device, the first playing device directly enters the stereo playing mode.
And 102, taking the first playing device as a main playing device to carry out wireless communication connection with a sound source device.
Specifically, for convenience of description, after the first playing device enters the stereo playing mode, the first playing device is defaulted as a master playing device, the playing device is wirelessly connected to a sound source device (the sound source device is used for providing sound source signals, such as a mobile phone, a computer, an MP3, and the like), the slave device serving as the sound source device receives the signal from the sound source device and is responsible for sending corresponding channel data to another playing device (hereinafter, referred to as a second playing device) for formation with the sound source device, and when the first playing device communicates with the second playing device, the first playing device serves as the master device, and the second playing device serves as the slave device.
Illustratively, the first playing device serves as a main playing device, and sends a team formation request to other playing devices accessing the broadcast networking, so as to obtain information of available playing devices, and complete playing of stereo sound in a form of a group of 2 playing devices with another available playing device in the broadcast networking.
And 104, selecting one playing device as a slave playing device of the first playing device according to the received reply of the other device.
Specifically, there may be a plurality of playback devices available in the broadcast networking, and after sending the request for grouping, the first playback device may receive replies from a plurality of playback devices that are not grouped, and the first playback device selects one of the playback devices as its slave playback device to perform channel grouping.
For example, the method of selecting the slave playback devices may be that the first playback device selects one of the playback devices as the slave playback device for channel grouping according to a predetermined rule, such as the playback device that replies to the grouping request with the received first playback device as the slave playback device; or taking the playing device closest to the received reply as a slave playing device; or the playing device with the best signal quality in the received reply is used as the slave playing device, and the like.
According to the stereo configuration method for the broadcast networking, the main playing device can be automatically determined without manual setting of a user, and the main playing device and other devices in the broadcast networking are played together after being formed into a team, so that the playing setting of the user is greatly facilitated, and the user experience is improved.
Optionally, after determining the slave playback device according to the reply from the other device, the method further includes:
transmitting the sound channel information of the master playing device to the slave playing device;
and configuring the sound channels of the master playing device and the slave playing device according to the sound channel confirmation information sent by the slave playing device.
Illustratively, after entering the team stereo playback mode, two playback devices (e.g., two speakers and two headphones) enter a peer-to-peer communication mode in which the two playback devices communicate with each other based on a control channel (control train).
As will be understood by those skilled in the art, the Control train is a Control channel defined by the bluetooth wireless communication protocol and capable of implementing data interaction such as Control commands.
Optionally, after selecting one playing device as the slave playing device according to the received reply from the other playing devices, the method further includes:
generating a new synchronous word by the master playing device and sending the new synchronous word to the slave playing device;
after receiving the synchronization word confirmation information fed back by the slave playing device, communicating with the slave playing device based on a new synchronization word after a preset time;
the new sync word is different from a default sync word used for broadcast networking communications and is unique in the broadcast networking;
the master playback device sends a queue formation request based on the default sync word and/or communicates with the slave playback device before communicating with the slave playback device based on the new sync word.
Specifically, in the 1-N mode, all devices in the broadcast networking communicate based on a default synchronization word, and after the 1-N mode is switched to the stereo play mode, before a new synchronization word is configured, the default synchronization word in the 1-N mode used for communication between the master play device and the slave play device is communicated; for example, the master playback device sends a new sync word to the slave playback device via the default sync word.
Specifically, after the preset time, the master playback device communicates with the slave playback device based on the new sync word, which can ensure that the master playback device and the slave playback device communicate through the old sync word (such as the default sync word) before the new sync word is used, and can ensure that the master playback device and the slave playback device can receive information of each other before the team formation is completed, thereby avoiding missing information reception caused by inconsistent use time of the new sync word.
Illustratively, before the master playback device and the slave playback device communicate with each other based on the new sync word, the master playback device and the slave playback device perform the following operations, respectively:
the method comprises the steps that a main playing device generates a new synchronous word, the new synchronous word is sent to a slave playing device through an old synchronous word, feedback information of the slave device is received, and communication is carried out based on the new synchronous word after preset time (such as delay of 500 ms) elapses;
and the slave playing device receives the new synchronous word sent by the master device, sends feedback information to the master playing device through the old synchronous word, and performs communication based on the new synchronous word after a preset time (such as after 500ms delay).
For example, the bluetooth master playback device (Dut1) and the bluetooth slave playback device (Dut2) wirelessly communicate via bluetooth, and the channel team formation process is further described as follows:
dut1 Host generates 6 byte new synchronous word according to local Bluetooth address, and broadcasts out by default synchronous word in 1-N mode through control channel;
dut2, after receiving the synchronization word, Dut2 Host sends the synchronization word confirmation information to Dut1 through the control channel by adopting the default synchronization word, stores the new synchronization word, and after delaying for 500ms, carries out communication based on the new synchronization word;
dut1 receives the sync word confirmation message and after 500ms delays it to communicate with Dut2 based on the new sync word.
Specifically, the above steps are a synchronization word configuration process, two playing devices performing channel grouping first adopt a default synchronization word in a 1-N mode to complete channel grouping, and when the two groups are played in a left-right channel mode, in order to prevent interference by other devices in the broadcast networking, a new synchronization word is configured, and the new synchronization word is used for communication between the two paired master and slave playing devices. For example, there are 9 playing devices in the broadcast networking, the first playing device and the second playing device channel team (group 1, sync word 1), the third playing device and the fourth playing device channel team (group 2, sync word 2), the fifth playing device and the sixth playing device channel team (group 3, sync word 3), the remaining 3 playing devices continue to keep playing in 1-N mode (sync word 0), after successful configuration, the sync words 0, 1, 2, 3 are different, and each playing device and the playing device in 1-N mode do not affect each other.
It can be understood that the Host and the Controller are terms in the bluetooth software/protocol, the Host mainly refers to the upper layer bluetooth protocol software, and the Controller refers to the lower layer bluetooth protocol software; each bluetooth device has its own Host and Controller code.
Optionally, after selecting one playing device as the slave playing device according to the received reply from the other playing devices, the method further includes:
storing the new synchronous words and the successfully configured sound channel information into historical team formation information;
when configuring the sound channel of the main playing device, when the history team formation information does not exist in the main playing device, setting the current sound channel of the main playing device as a left sound channel or a right sound channel;
and when the history team forming information exists in the main playing device, taking the history sound channel stored in the history team forming information as the current sound channel of the main playing device.
Specifically, after the playing device selected by the user is used as the main device, if the historical team formation information does not exist in the main playing device, the main playing device is defaulted to play the left channel; and if the playing equipment has the historical team forming information, confirming the sound channel played by the playing equipment according to the record in the historical team forming information.
For example, if in the history team recording, the playing device selected by the user at this time plays the right channel as the slave device in the last team, then in this playing, since the user selects this playing device, the playing device enters the team stereo playing mode first, and thus the device plays the right channel as the master device in this playing.
Optionally, configuring the channels of the master playback device and the slave playback device according to the channel confirmation information sent by the slave playback device includes:
if the sound channel of the slave playing device is different from the sound channel of the master playing device, the sound channel configuration is successful;
and if the sound channel of the slave playing equipment is the same as that of the master playing equipment, adjusting the master playing equipment and the slave playing equipment to different sound channels.
Specifically, since stereo playback is required, that is, two playback devices can not be the left channel or the right channel, and they must play back different channels, it is necessary to ensure that the channels of the master playback device and the slave playback device are different when configuring.
If the master playing device is the right channel at this time, the channel information is sent to the slave playing device, and if the slave playing device is the left channel at this time, the slave playing device returns channel confirmation information, and the channel configuration is successful; if the slave playing device is also the right channel at this time, an error occurs, the user can be prompted to control the channel repetition at the end, the channel configuration can be completed by manually modifying the channels of the master playing device and the slave playing device by the user, and the channel of one of the playing devices can be automatically switched to ensure that the two playing devices play different channels to complete the configuration.
It should be noted that, there is no precedence relationship between the steps of setting the synchronization word and configuring the left and right channels in the above steps, and a new synchronization word may be configured first, and then the left and right channel information of the master playback device and the slave playback device may be configured.
Optionally, the sending the team formation request to other playing devices in the broadcast networking includes:
if the historical team formation information is stored in the first playing device, the first playing device is connected with another playing device according to the historical team formation information after entering a stereo playing mode, and stereo playing is carried out together.
Optionally, the sending the team formation request to other playing devices in the broadcast networking includes:
if the historical team formation information is stored on the playing device, the playing device is connected with another corresponding playing device in the team formation information after entering a stereo playing mode, and the playing device and the other playing device play together.
Specifically, the playing device with the historical team formation information directly enters a stereo playing mode after receiving a first operation executed by a user, and completes channel team formation by another playing device directly corresponding to the historical team formation information, and plays the audio channel with the channel configuration recorded in the historical team formation information; illustratively, the first operation is as follows: the user clicks 'power on', the user inputs an instruction to enter the broadcast networking, and the like.
Specifically, if there is a playing device a with historical team formation information, when a first operation performed by a user is received to enter a stereo playing mode and a team is formed with another playing device B, if a team formation failure occurs, for example: another playback device B is not nearby, and another playback device B has a failed lamp; under the condition, prompting a user that a problem occurs in a control end team, wherein the user can perform related manual setting, if the user does not perform related operation, a playing device A with historical team forming records cannot complete team forming within preset team forming time, generating prompting information, and automatically switching to a 1-N mode for playing; if the playing device B appears in the connection range later, the user can operate the playing device B or the playing device a to become the master device to perform the team formation again.
Specifically, if the history team formation information is stored in the main playback device, after the main playback device enters the stereo playback mode, the main playback device sends a team formation request to other playback devices in the broadcast networking based on the synchronization word in the history team formation information.
At this time, among other playing devices in the broadcast networking, the playing device which does not enter the stereo playing mode is based on the default synchronous word communication in the 1-N mode, so that the team formation request cannot be received; and if the synchronous word of one of the other playing devices is the same as the synchronous word of the main playing device, the other playing devices entering the stereo playing mode can receive the team formation request and further complete the team formation with the main playing device.
It should be noted that the playback device that first enters the stereo playback mode will be connected to the sound source device as the main playback device.
The method greatly facilitates the sound effect configuration of the user, the playing equipment with the historical team formation information automatically determines the master playing equipment, the slave playing equipment and the respective responsible sound channels after starting up, and completes the stereo playing of the two channel teams, so that the current playing equipment configuration (such as sound effect configuration under a complex scene) of the user can be quickly restored and repeatedly used without secondary setting, the user experience degree is greatly improved, and the sound configuration efficiency of the user is improved.
Exemplarily, referring to fig. 2, a process of sending a team formation request by a master playback device is shown, and the stereo playback setting method provided in the embodiment of the present application is further described:
in the 1-N mode, a user selects one playing device in a scene as a first playing device, and a first operation executed by the user enables the first playing device to enter a stereo playing mode, and the first playing device is used as a main playing device.
The first playing device broadcasts a 'team formation request' command through a control channel, receives team formation replies of other playing devices within preset time, determines one of the teamformation replies as a slave playing device, and enters playing configuration (configures a synchronous word and a sound channel).
It is understood that the playback devices in the broadcast network that have entered stereo playback mode and have been queued with other playback devices will not reply to the queue request from the first playback device, i.e., only playback devices in the broadcast network that have not been queued and/or have no history of queue records will reply to the queue request from the first playback device.
Optionally, the method further includes:
if the first playing device is in the stereo playing mode and has successfully formed a team with another playing device, the first playing device also exits the stereo playing mode when the another playing device exits the stereo playing mode.
Specifically, no matter the master playing device or the slave playing device, as long as any one of the two playing devices with the channel grouping relationship exits the stereo playing mode, the other playing device also exits the stereo playing mode, which is convenient for the user to switch between the stereo playing mode and the 1-N playing mode, and only any one device in the group needs to be switched to enter the 1-N mode, the device grouped with the device also automatically enters the 1-N mode.
Illustratively, in the stereo play mode, if the first play device needs to exit the stereo play mode based on the second operation of the user, the first play device sends an exit request to the second play device, and the second play device replies a confirmation message; the first playing device exits the stereo playing mode after receiving the confirmation message, and the second playing device also exits the stereo playing mode.
Optionally, the historical team formation information of the playing device is cleared according to a third operation performed by the user.
Illustratively, if the user presses the "Play" key on the playback device for a long time, the playback device exits the sound source team mode and clears the historical team information on the device.
Illustratively, if the first playback device deletes the historical team information (sync word and channel information) that is stored in the historical team information and that communicates with the second playback device in the stereo playback mode, based on a third operation by the user; similarly, the second playback device deletes the historical team formation information. After the stereo playing mode is entered next time, the two playing devices need to be re-queued for stereo playing.
