As mobile phone applications have begun to become wireless, mobile phones can connect to multiple multimedia devices in a wireless manner (such as wifi and bluetooth), and users begin to request that the same piece of music can be played on multiple devices at the same time. For example, two real wireless bluetooth headsets are connected to the mobile phone, music is played at the mobile phone end, the music can be played on the two bluetooth headsets simultaneously, and audio received by the two bluetooth headsets has no time delay.
In some implementations, although the mobile phone can be supported to connect two bluetooth headsets and play music on the bluetooth headsets synchronously, if the mobile phone is connected with one bluetooth device (connected in a bluetooth mode), and in addition, the mobile phone is connected with an audio device (connected in a wifi mode) through wifi, because the two transmission modes are different, and the wifi transmission is easily interfered, the phenomenon that the audio transmission is asynchronous easily occurs, as a result, the two paths of sounds are asynchronous, and the actual experience of a user is very poor.
In some implementations, only audio low-delay synchronous playing of a plurality of bluetooth devices connected to a mobile phone can be realized, but audio low-delay synchronous playing between bluetooth and wifi devices cannot be realized at present. The mobile phone end plays music on the audio equipment end through the Bluetooth, but the current research is not as deep as that of playing music on the audio equipment through the Bluetooth, and the scheme is not as mature, but a part of wifi equipment exists in the actual market. In addition, the audio played by connecting the wifi device through wifi is generally fixed on a channel to work, and transmission packet loss is easily caused by interference. Therefore, music cannot be played on the Bluetooth device and the wifi device synchronously on the mobile phone well.
The foregoing description is provided for general background information and is not admitted to be prior art.

Detailed Description
As described in the background art, in some implementations, a mobile phone can only implement low-delay synchronous audio playing of multiple bluetooth devices, and cannot implement synchronous playing of multiple audio devices. For example, for bluetooth devices and wifi devices (such as wifi loudspeaker boxes) on the market, when a user connects multiple bluetooth devices with a mobile phone, multiple bluetooth devices can play audio simultaneously, but when the mobile phone connects the bluetooth devices and the wifi devices simultaneously, the audio played by bluetooth connection is relatively stable, the delay is small, transmission packet loss cannot be caused, the audio played by wifi connection is generally fixed on a channel to work, although the bandwidth is relatively high, the delay is very long, and the transmission packet loss (audio data loss) is caused by interference. When a user needs two audio devices to play audio simultaneously, a delay error exists, synchronous non-delay playing of the two audio devices cannot be realized, and the use experience of the user is reduced.

Specifically, the electronic terminal device is connected with at least two playing devices, and a user generates multimedia data on the electronic terminal device and sends audio data to the playing devices according to different rules. By adopting the technical means, the problem that various playing devices on the market cannot play multimedia data synchronously is solved, different use requirements of users can be met, the use experience of the users is greatly improved, and the satisfaction of the users is improved.

Example two
Based on the characteristics of the first embodiment, as shown in fig. 4, this embodiment includes another method for playing multimedia, where the method is applied to a terminal device, and specifically includes: the T1 and the electronic terminal device are connected with the Bluetooth device and the wifi device; t2, generating multimedia data by the electronic terminal equipment; t3, creating a buffer area for controlling the sending speed of the multimedia data on the electronic terminal equipment, storing the generated multimedia data in the buffer area, and sending the multimedia data to the playing module respectively; and T4, the electronic terminal equipment respectively sends the multimedia data to the playing module according to the control strategy.
Wherein the multimedia data is generated by a multimedia module of the electronic terminal device. The buffer zone comprises buffer zones of various playing modules, and in the embodiment, the created buffer zone comprises a Bluetooth device buffer zone and a wifi device buffer zone. The Bluetooth device buffer area sends multimedia data to the Bluetooth device through a Bluetooth data channel, and the wifi device sends the multimedia data to the wifi device through a wifi data channel.
After the electronic terminal device is connected with the Bluetooth device and the wifi device, 10 probe frames are respectively sent to the Bluetooth data channel and the wifi data channel, the round trip time RTT of the probe frames is respectively counted, and the round trip time RTT is used as the normal synchronization time.
In this embodiment, the round trip time of each probe frame in the bluetooth data channel is a first round trip time RTT1, which is an average value of the round trip times of each probe frame in the bluetooth data channel; the round trip time of each probe frame in the wifi data channel is a second round trip time RTT2, which is an average value of the round trip times of each probe frame in the wifi data channel.
The control strategy in the step T4 is: and after the multimedia data pass through the buffer area, the multimedia data are simultaneously or delayed for a period of time and sent to the playing module to be played. And selecting to send the multimedia data at the same time or with a delay according to the time difference of the multimedia data transmitted to each playing module by the electronic terminal equipment. The time difference is specifically: if the time for transmitting the multimedia data to the two playing modules by the electronic terminal equipment is time A and time B respectively, the transmission time difference is the absolute value of the difference value of the time A and the time B.
The control strategy specifically comprises the following steps: when the multimedia data is transmitted to the playing modules with delay (the time difference is not zero), comparing the transmission time difference of each playing module, and transmitting the multimedia data by delaying the corresponding transmission time difference so as to ensure that different playing modules play simultaneously; and when no delay exists in the transmission of the multimedia data to the playing modules (the time difference is zero), the multimedia data are simultaneously sent to different playing modules.
In this embodiment, the multimedia data is played by clicking, and the multimedia data is sent to the bluetooth data channel through the bluetooth device buffer area and is sent to the wifi data channel through the wifi device buffer area.
When the first round trip time RTT1 of the Bluetooth data channel is inconsistent with the second round trip time RTT2 of the wifi data channel, solving a first round trip time difference delta RTT1Said first round trip time difference Δ RTT1Is the absolute value of the difference between the first round trip time RTT1 and the second round trip time RTT2, i.e. Δ RTT1＝|RTT1-RTT2|。
In this embodiment, the first round trip time RTT1 is smaller than the second round trip time RTT2, and when the buffer sends the multimedia data to the wifi data channel, the buffer delays the first round trip time difference Δ RTT1And then sending the multimedia data to a Bluetooth data channel so as to enable the Bluetooth equipment and the wifi equipment to synchronously play audio. Of course, in other embodiments, if the first round trip time RTT1 is greater than the second round trip time RTT2, the buffer delays the first round trip time difference Δ RTT from the time when the buffer sends the multimedia data to the bluetooth data channel1And then, the multimedia data is sent to a wifi data channel, so that the Bluetooth device and the wifi device synchronously play audio.
Because the multimedia data played by wifi connection is generally fixed on a wifi data channel for transmission, although the bandwidth ratio is higher, the delay is very long, and the transmission packet loss is easily caused by interference. Therefore, in order to ensure the multimedia data transmission efficiency, the method for playing multimedia of the present application further includes: the electronic terminal device monitors the error rate and the packet loss rate of multimedia data transmission in the wifi data channel in different time periods, and when the error rate and the packet loss rate change value of the wifi data channel in the adjacent time period do not meet preset conditions (in this embodiment, when the error rate and the packet loss rate are continuously increased, and the increase range is continuously increased), the difference of the transmission time of the multimedia data transmission of different playing modules is re-judged and adjusted.
The method specifically comprises the following steps of monitoring the bit error rate and the packet loss rate of multimedia data transmission in wifi data channels in different time periods: monitoring values of an error rate and a packet loss rate in n fixed time periods in a wifi data channel, respectively defining the values of the error rate and the packet loss rate in each time period as T1, T2, T3,. cndot., Tn, and calculating a difference value delta T (n) between the error rate and the packet loss rate in adjacent time periods, wherein the delta T (n) is T (n +1) -T (n). In this embodiment, the fixed period is 50ms, and the n fixed periods are 5 fixed periods.
The specific steps of re-judging and adjusting the transmission time difference of the multimedia data transmitted by different playing modules are as follows: the buffer resends a number of probe frames (which may be 10) to the wifi data channel; calculating the average round trip time of each probe frame as the third round trip time RTT3 of the wifi device; the buffer adjusts a transmission time of the multimedia data according to the first round trip time RTT1 and the third round trip time RTT 3.
When the first round trip time RTT1 and the third round trip time RTT3 are consistent, the buffer zone simultaneously sends multimedia data to the Bluetooth data channel and the wifi data channel, so that the Bluetooth device and the wifi device synchronously play audio.
When the first round trip time RTT1 and the third round trip time RTT3 do not coincide, a difference between the third round trip time RTT3 and the first round trip time RTT1 is calculated, and the absolute value of the difference is used as the second round trip time difference Δ RTT2. And after the audio of the electronic terminal equipment starts to play, the multimedia data enters a buffer zone. The buffer zone sends multimedia data to the wifi data channel, and the buffer zone delays a second round-trip time difference delta RTT2And then sending the multimedia data to a Bluetooth data channel so as to enable the Bluetooth equipment and the wifi equipment to synchronously play audio. In other embodiments, the buffer transmits multimedia data to the bluetooth data channel, the buffer delaying a second round trip time difference Δ RTT2And then, the multimedia data is sent to a wifi data channel, so that the Bluetooth device and the wifi device synchronously play audio.
In addition, the present application also provides an electronic terminal device using the method for synchronously playing audio by multiple playing modules, the electronic terminal device is implemented based on a system for synchronously playing audio by multiple playing modules, the system for synchronously playing audio by multiple playing modules comprises: the device comprises an audio module, a buffer module, a data channel module and a control module.
